This preprint studied UTP23 (UTP23 small subunit processome component) as a prognostic biomarker in breast cancer by analyzing TCGA and GEO datasets for UTP23 mRNA, Human Protein Atlas for protein expression, and by relating high vs low UTP23 to overall survival, differential gene expression, and pathway enrichment (GO/KEGG and GSEA), along with immune infiltration estimates (ssGSEA and TIMER). The authors found UTP23 upregulated in breast cancer versus normal tissues, that higher UTP23 expression was associated with poorer overall survival, and that UTP23 expression correlated with humoral immune response signals and positively with immune cell infiltration. In vitro, knocking down UTP23 with siRNAs inhibited proliferation of the breast cancer cell lines MDA-MB-231 and HCC-1806; a key caveat is that the work is based largely on in silico analyses using public datasets plus limited cell-line validation and is not peer reviewed. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

Abstract Background Breast cancer is one of the malignant tumors with a high incidence and mortality rate among women worldwide, and its prevalence is increasing year by year, posing a serious health risk to women. UTP23 (UTP23 Small Subunit Processome Component) is a nucleolar protein that is essential for ribosome production. As we all know, disruption of ribosome structure and function results in improper protein function, affecting the body's normal physiological processes and promoting cancer growth. However, little research has shown a connection between UTP23 and cancer. Methods We analyzed the mRNA expression of UTP23 in normal tissue and breast cancer using The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database, and the protein expression of UTP23 using The Human Protein Atlas (HPA) database. Next, we examined the relationship between UTP23 high expression and Overall Survival (OS) using Kaplan-Meier Plotters and enriched 980 differentially expressed genes in UTP23 high and low expression samples using GO/KEGG and GSEA to identify potential biological functions of UTP23 and signaling pathways that it might influence. Finally, we also investigated the relationship between UTP23 and immune infiltration and examined the effect of UTP23 on the proliferation of human breast cancer cell lines by knocking down UTP23. Results We found that UTP23 levels in breast cancer patient samples were noticeably greater than those in healthy individuals and that high UTP23 levels were strongly linked with poor prognoses ( P  = 0.008). Functional enrichment analysis revealed that UTP23 expression was connected to the humoral immune response. Besides, UTP23 expression was found to be positively correlated with immune cell infiltration. Furthermore, UTP23 knockdown has been shown to inhibit the proliferation of human breast cancer cells MDA-MB-231 and HCC-1806. Conclusion Taken together, our study demonstrated that UTP23 is a promising target in detecting and treating breast cancer and is intimately linked to immune infiltration.

UTP23 TCGA Breast cancer Biomarker immune infiltration Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Figure 7 Figure 8 Introduction Breast cancer is a frequent disease among women all over the world, with an average of one in four women getting the diagnosis. It has seriously threatened the health of women around the world [ 1 – 3 ] . The National Cancer Institute of the United States proposed the concept of tumor molecular typing in 1999; four types of breast cancer were identified luminal A, luminal B, human epidermal growth factor receptor2 enriched (HER2), and triple-negative/basal-like breast cancer [ 4 – 7 ] . The mainstay of breast cancer treatment has involved surgical resection, chemotherapy, radiation, and targeted therapy. Conventional chemotherapy drugs including paclitaxel、anthracyclines and alkylating agents, easily lead to systemic side effects and toxicities, whereas targeted drug therapy is expensive and out of reach for most families [ 8 , 9 ] . Moreover, patients who are resistant to conventional treatment will experience rapid declines in quality of life and survival rates [ 10 , 11 ] . Therefore, finding new prognostic and predictive biomarkers is critical for patients to improve outcomes. UTP23 (UTP23 Small Subunit Processome Component) is necessary for the early processing of 18S ribosomal RNA and is mildly associated with preribosomal particles [ 12 ] . Moreover, it was discovered that UTP23 has the predicted PIN domain [ 13 ] . Research shows that the PIN domain is an endoribonuclease that participates in RNA degradation and processing aspects. One of UTP23's most important functional modules is its N-terminal helix 1, which may play a role in rRNA binding to the pre-90S ribosome [ 14 , 15 ] . Cell homeostasis and ribosome synthesis are intimately linked, dysregulation of any of these processes is likely to cause cell death and uncontrolled cell growth [ 16 ] . UTP23 was previously recognized as one of the most significant nuclear regulatory genes [ 17 ] . Furthermore, there is evidence that ovarian cancer patients with UTP23 overexpression are significantly more sensitive to paclitaxel [ 18 ] . However, there are no studies on its role in breast cancer. To learn more about the part UTP23 plays in the emergence of breast cancer, this study examined UTP23 mRNA and protein expression in breast cancer patients by using data from the TCGA database and confirmed it as a potential target for breast cancer treatment. Furthermore, GO/KEGG analysis discovered that UTP23 was probably connected to the humoral immune response. Finally, we investigated UTP23 expression on a selection of breast cancer cell lines, showing that knockdown of UTP23 effectively inhibited the growth of either HCC1806 or MDA-MB-231 breast cancer cells. In conclusion, We determined that UTP23 is a very promising target for breast cancer therapy through database mining and bioinformatics analysis, which was further supported by in vitro knockdown of UTP23. Methods Cell lines Cells were purchased from ATCC, all identified by Short Tandem Repeat (STR), MDA-MB-231 culture conditions: DMEM/F12 medium (GIBCO, USA) plus 10% FBS, 37 degrees 5% CO2; HCC-1806 culture conditions: RPMI 1640 medium (GIBCO, USA) plus 10% FBS, 37 ℃ 5% CO2. Reagent Nontargeting siRNA (siNC) and siRNA (siUTP23#1 and siUTP23#2) and were purchased from Shanghai Generay Biotech Co., Ltd (Shanghai, China) and stored at -20 ℃ away from light. The sequence of NC is 5′-UUCUCCGAACGUGUCACGUTT-3′. The sequences of siUTP23#1 and siUTP23#2 are 5′-GGUUGUUUCUCCAGGUAAATT-3′and 5′-GGUAGUGUUUGGAUUGCAATT-3′. RNA isolation and qRT-PCR assay The primes were obtained from Shanghai Generay Biotech Co., Ltd (Shanghai, China). All reagents mentioned below were obtained from Vazyme Biotech (Nanjing, China). The total RNA was extracted from cells using TRIzol Reagent. The cDNA was reverse transcribed with the HiScript QRT SuperMix. The isolated mRNA quantity was measured with the SYBR Green master mix. The primes sequences used were: UTP23 forward GCTTCTTCCGCAACAACTTCG; UTP23 reverse CCTTTCCCAATGTTTCTAGCTCT; GAPDH forward TCACCACCATGGAGAAGGC; GAPDH reverse GCTAAGCAGTTGGTGGTGCA. The qRT-PCR was performed as previously described [ 19 ] . cell proliferation assay The cells infected with indicated siRNA were performed using 200,000 cells per well in a 6-well plate for 24h. Then cells were plated in a 96-well microplate with 2,000 cells and 200uL medium per well. On days 1,2,3,4, the MTT assay determined the values. MTT assays were performed as previously described [ 20 ] . Clone formation assays Cells in good condition at logarithmic growth stage were spotted into 6-well plates at a density of 1000 cells per well, cultured for 10 days, the supernatant was discarded, washed twice with PBS, and stained with 1% crystal violet solution. Public datasets and data processing RNA-seq data of breast cancer tissues were obtained from The Cancer Genome Atlas (TCGA) database. The Data were processed using the software R 3.6.3 version: the "ggplot2" package was used for data visualization, the “stat” package was used for single gene correlation analysis, and the “ComplexHeatmap” package was used to visualize the heatmap, “DESeq2” package was used for single gene difference analysis. Enrichment analysis with the “clusterProfile” package, and difference analysis with the “limma” package. Single gene difference analysis The breast cancer patients were split into two groups according to median UTP23 expression levels: the UTP23 high expression group and the UTP23 low expression group. R “DESeq2” package was used for single gene difference analysis. |log2(FC)|>1, and a P values < 0.05 were considered a statistically different result. Functional enrichment analysis The R “clusterProfiler” package was used for Gene ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. GSEA 2.0 was used to analyze gene sets derived from the MSigDBCollection or published gene signatures. Survival analysis The impact of UTP23 high expression on clinical outcomes of breast cancer patients were analyzed using Kaplan-Meier plots ( http://kmplot.com/analysis ). Immune cell infiltration analysis The association between UTP23 and immune cell infiltration was examined using the ssGSEA (single sample GSEA) algorithm. The relevance of related gene expression and immune cell infiltration was investigated through the Tumor Immune Estimation Resource (TIMER) database ( https://cistrome.shinyapps.io/timer ). Statistical analysis The results are the mean ± standard deviation (SD). A p-value of 0.05 was considered statistically significant on GraphPad Prism 8.0. Results UTP23 was upregulated in BRCA The pan-cancer analysis of UTP23 showed that UTP23 was significantly overexpressed in almost all tumors (Fig.1A), including Breast invasive carcinoma (BRCA)、Cholangiocarcinoma (CHOL)、Colon adenocarcinoma (COAD)、Lymphoid Neoplasm Diffuse Large B-cell Lymphoma (DLBC)、Esophageal carcinoma (ESCA)、Glioblastoma multiforme (GEM)、Head and Neck squamous cell carcinoma (HNBC)、Kidney renal clear cell carcinoma (KIRC)、Acute Myeloid Leukemia (LAWL)、Brain Lower Grade Glioma (LGG)、Liver hepatocellular carcinoma (LIHC)、Lung adenocarcinoma (LUAD)、Lung squamous cell carcinoma (LUSC)、Ovarian serous cystadenocarcinoma (OV)、Pancreatic adenocarcinoma (PAAD)、Rectum adenocarcinoma (READ)、Skin Cutaneous Melanoma (SKCM)、Stomach adenocarcinoma (STAD)、Testicular Germ Cell Tumors (TGCT)、Thyroid carcinoma (THCA)、Thymoma (THYM)、Uterine Corpus Endometrial Carcinoma (UCEC)、Uterine Carcinosarcoma (UCS). Analysis of the TCGA database showed that the expression of UTP23 mRNA in tumor tissues was much higher than that in normal tissues (Fig.1B) and their corresponding adjacent tissues (Fig.1C). The same results also appeared in the analysis of the GSE22820 and GSE36295 datasets (Fig.1D-E). Furthermore, we discovered that UTP23 levels were generally higher in white patients than in other ethnic groups, and there was no significant difference in UTP23 levels in tissues of patients who received radiation therapy versus those who did not (Fig.1F-G). The content of UTP23 protein in tumor tissue was also significantly higher than that in normal tissue (Fig.2). High UTP23 expression has adverse effects on BRCA survivors 1083 cancer patients were identified based on the median value for the expression level of UTP23 mRNA in BRCA, with 542 being categorized as high and 541 as low. A detailed description of the clinicopathological features can be found in Table 1. Kaplan-Meier analysis revealed that patients with high UTP23 expression in the TCGA-BRCA data set had poorer overall survival (OS) than those with low expression ( P =0.008, Fig.3A). We also analyzed the OS of T stage, N stage, and M stage, and found that UTP23 expression was strongly correlated with OS in early disease in the early stage of the disease, while the relationship with prognosis was not very significant in the later stage of the disease (Fig.3B-G). Subgroup analysis indicated that there was a significant correlation between OS and UTP23 expression in patients who did not receive radiation therapy, but not in patients who did (Fig.3H-I). Furthermore, multivariate analysis showed that PAM50 and age were also very substantially related to overall survival. Patients with Her2 positive and basal breast cancer had worse overall survival, and those older than 60 years also had worse overall survival than younger patients (Table.2).

A volcano plot illustrates the DEGs' expression profiles (Fig.4A). Additionally, we analyzed the co-expressed genes of UTP23, in which RAD21 was the most associated gene with UTP23 expression (Fig.4B), and it has been previously shown to be associated with poor prognosis in breast cancer, which adds to the evidence that UTP23 may be associated with poor prognosis in breast cancer [21] . In the analysis of DEGs enriched in GO analysis and KEGG pathways, we found that the biological process in which UTP23 most likely to be involved included humoral immune respond、defense response to bacterium、antimicrobial humoral response, and the molecular function it was most likely to affect were endopeptidase inhibitor activity、hormone activity、receptor ligand activity and the cellular component it was most likely to affect were nucleosome、high-density lipoprotein particle、cornified envelope (Fig.4C). Genes associated with each signaling pathway were plotted in Fig.4D. The top 6 GO items and KEGG objects enriched for DEGs are shown in Fig.4E and Fig.4F, respectively. We also performed a GSEA analysis and found that the top 9 data sets with the most significant relationship with UTP23 were signaling by Rho GTPases, M phase, cell cycle checkpoints, neuronal system, deubiquitination, DNA repair, signaling by wnt, transmission across chemical synapses, chromatin-modifying enzymes (Table3, Fig.5). Furthermore, we draw UTP23-interaction proteins in the BRCA tissue network by using the STRING database (Fig.6A) and showed their co-expression scores with UTP23 (Fig.6B).

Figure.7A shows the relationship between immune cell infiltration and UTP23 mRNA expression. UTP23 expression was positively correlated with Th2 cells ( P <0.001, r=0.332) and Tcm ( P <0.001, r=0.332), and negatively correlated with pDC ( P <0.001, r=-0.456) and CD8 + T cells ( P <0.001, r=-0.253), while Tem ( P =0.983, r=0.001) had no relationship with UTP23 expression (Fig.7). Furthermore, the enrichment scores corroborate previous findings, with higher UTP23 expression associated with higher enrichment scores of Tcm, Th2 cells, T helper cells, and Tgd (Fig. 7G). Inhibition of UTP23 can effectively inhibit the proliferation of breast cancer cells To confirm that UTP23 is an important target for breast cancer treatment, we carried out qRT-PCR of UTP23 on multiple breast cancer cells, the results showed that the UTP23 expression in breast cancer was indeed higher than that in normal breast cells MCF10A, especially the triple-negative breast cancer cell lines HCC-1806, MDA-MB-231, etc (Fig.8A). Subsequently, we confirmed that knockdown of UTP23 can effectively inhibit the proliferation of HCC-1806 and MDA-MB-231 by growth curve assay (Fig.8D-E) and clone formation assay (Fig.8F-G). Discussion Ribosome synthesis is a complex, highly dynamic cellular metabolic process that requires many conserved assembly factors, and approximately fifty ribosomal proteins (r-protein) bind to ribosomal RNA (rRNA) during co-transcriptional processes [ 22 – 25 ] . UTP23 is a new small subunit processing component, which is a conserved protein factor involved in the early assembly of ribosomal small subunits and plays an important role in the ribosome assembly process, structurally important regions include the C-terminal tail, zinc finger, helix α1, and the highly conserved PIN domain [ 15 ] . Studies early on focused mainly on the structure and function of UTP23, with few attempting to determine how it contributes to tumorigenesis and progression [ 15 , 26 ] . Here, we analyzed UTP23 with the TCGA database, GEO database and HPA database and found that its mRNA and protein expression in breast cancer was significantly higher than that in normal tissues, and its expression did not differ significantly between radiation therapy and non- radiation therapy patients, which means that if a patient is treated with radiation, it does not make UTP23-targeted drugs any less effective in treating him. For those who are fighting breast cancer, this is crucial. In addition, through Kalan-Meier analysis, we found that poor patient outcomes were associated with high UTP23 expression in breast cancer, and UTP23 was more significantly associated with poor patient prognosis in the early stage of the disease, suggesting its potential as a diagnostic and prognostic indicator. In other words, it is possible to dramatically increase the early diagnosis rate of breast cancer by identifying UTP23 expression in the early stages of the disease. However, it is necessary to further verify whether UTP23 can serve as a useful diagnostic and prognostic marker for different stages of breast cancer progression. In the research, functional enrichment analysis revealed that UTP23 may be involved in the humoral immune response, defense response to the bacterium, antimicrobial humoral response, which suggested that UTP23 may be closely related to the human immune system. Besides, GSEA analysis showed that UTP23 expression was related to signaling by Rho GTPases, M phase, cell cycle checkpoints, neuronal system, deubiquitination, DNA repair, signaling by wnt, transmission across chemical synapses, and chromatin-modifying enzymes. ssGSEA showed that UTP23 expression has a positive correlation with the infiltration of immune cells, including Tcm, Th2 cells and T helper cells. We also explored gene networks connected to UTP23 with STRING, noticing that KRR1 got the highest score, which has been previously reported as a type of tumor-associated antigens (TAAs) and has the potential to be used as a target for tumor vaccines [ 27 ] . But whether UTP23 can play a role as a TAA in tumor immunotherapy needed further investigation. To further explore the specific role of UTP23 in breast cancer, we analyzed the mRNA expression of UTP23 in a series of human breast cancer cells by qRT-PCR, and the results showed that UTP23 was significantly higher in breast cancer cells than in human normal breast cells. UTP23 knockdown significantly inhibited the proliferation of human breast cancer cells HCC1806 and MDA-MB-231, proving that it is a very potential new target for breast cancer. We also highlight the need to further explore the specific mechanism of UTP23 in the progression of breast cancer. Cancer has always been the leading cause of death in humans. Although medical technology has enabled humans to overcome many diseases, cancer remains an untapped resource [ 28 ] . Novel tumor therapies, such as antibody-coupled drugs, immune checkpoint inhibitors, tumor vaccines, and adoptive cellular immunotherapy, have emerged in recent years [ 29 – 32 ] . The well-known CAR-T therapy is a type of relay immune cell therapy that entails isolating autologous tumor-infiltrating lymphocytes (TIL) or peripheral blood lymphocytes from tumor patients, sorting them, expanding them, activating them in vitro, and then re-transfusing them into the patient to obtain anti-tumor immunity [ 33 , 34 ] . The substantial relationship between UTP23 and immune infiltration examined in this work leads to the conclusion that further research on UTP23 is urgently required since it may have huge application in cellular immunotherapy. In recent years, due to COVID-19, people have paid unprecedented attention to vaccines, and tumor vaccines have also become a hot track in tumor immunity [ 35 ] . According to studies, tumor cells contain tumor antigens that the immune system can recognize to distinguish them from healthy ones [ 36 – 38 ] . By expressing particular, immunogenic tumor antigens (such as peptides, DNA, and RNA) with the assistance of adjuvants such cytokines and chemokines, which in turn kill and eliminate tumor cells, tumor vaccines can activate or increase the body's natural anti-tumor immunity [ 39 , 40 ] . Interestingly, KRR1, which has previously been identified as a novel tumor-associated antigen, received the highest score in the STRING database analysis of UTP23-interacting proteins. This suggests that UTP23 is likely to be a noveltumor-associated antigen as well. Furthermore, based on the results of the bioinformatics analysis, we carried out experimental validation and verified that knockdown of UTP23 could successfully reduce the proliferation of breast cancer cells. Conclusions According to our findings, UTP23 was strongly expressed in breast cancer tissues and associated with poor outcomes, suggesting it may be useful both as a diagnostic and prognostic marker for breast cancer. In addition, UTP23 also be related to immune infiltration, and future research should be conducted to investigate the role of UTP23 in the breast cancer immunotherapy. Finally, we confirmed by knocking down UTP23 in HCC-1806 and MDA-MB-231 cells that inhibition of UTP23 significantly inhibited the proliferation of breast cancer cells Thus, we highlight UTP23 as a promising target for treating breast cancer in this study.

However, there are no studies on its role in breast cancer.\u003c/p\u003e \u003cp\u003eTo learn more about the part UTP23 plays in the emergence of breast cancer, this study examined UTP23 mRNA and protein expression in breast cancer patients by using data from the TCGA database and confirmed it as a potential target for breast cancer treatment. Furthermore, GO/KEGG analysis discovered that UTP23 was probably connected to the humoral immune response. Finally, we investigated UTP23 expression on a selection of breast cancer cell lines, showing that knockdown of UTP23 effectively inhibited the growth of either HCC1806 or MDA-MB-231 breast cancer cells. In conclusion, We determined that UTP23 is a very promising target for breast cancer therapy through database mining and bioinformatics analysis, which was further supported by in vitro knockdown of UTP23.\u003c/p\u003e "},{"header":"Methods","content":" \u003cdiv id=\"Sec3\" class=\"Section3\"\u003e \u003ch2\u003eCell lines\u003c/h2\u003e \u003cp\u003eCells were purchased from ATCC, all identified by Short Tandem Repeat (STR), MDA-MB-231 culture conditions: DMEM/F12 medium (GIBCO, USA) plus 10% FBS, 37 degrees 5% CO2; HCC-1806 culture conditions: RPMI 1640 medium (GIBCO, USA) plus 10% FBS, 37 ℃ 5% CO2.\u003c/p\u003e \u003c/div\u003e \u003cdiv id=\"Sec4\" class=\"Section3\"\u003e \u003ch2\u003eReagent\u003c/h2\u003e \u003cp\u003eNontargeting siRNA (siNC) and siRNA (siUTP23#1 and siUTP23#2) and were purchased from Shanghai Generay Biotech Co., Ltd (Shanghai, China) and stored at -20 ℃ away from light.

Analysis of the TCGA database showed that the expression of UTP23 mRNA in tumor tissues was much higher than that in normal tissues (Fig.1B) and their corresponding adjacent tissues (Fig.1C). The same results also appeared in the analysis of the GSE22820 and GSE36295 datasets (Fig.1D-E). Furthermore, we discovered that UTP23 levels were generally higher in white patients than in other ethnic groups, and there was no significant difference in UTP23 levels in tissues of patients who received radiation therapy versus those who did not (Fig.1F-G). The content of UTP23 protein in tumor tissue was also significantly higher than that in normal tissue (Fig.2).\u0026nbsp;\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eHigh UTP23 expression has adverse effects on BRCA survivors\u003c/strong\u003e\u003c/p\u003e\n\u003cp\u003e1083 cancer patients were identified based on the median value for the expression level of UTP23 mRNA in BRCA, with 542 being categorized as high and 541 as low. A detailed description of the clinicopathological features can be found in Table 1. Kaplan-Meier analysis revealed that patients with high UTP23 expression in the TCGA-BRCA data set had poorer overall survival (OS) than those with low expression (\u003cem\u003eP\u003c/em\u003e=0.008, Fig.3A). We also analyzed the OS of T stage, N stage, and M stage, and found that UTP23 expression was strongly correlated with OS in early disease in the early stage of the disease, while the relationship with prognosis was not very significant in the later stage of the disease (Fig.3B-G). Subgroup analysis indicated that there was a significant correlation between OS and UTP23 expression in patients who did not receive radiation therapy, but not in patients who did (Fig.3H-I). Furthermore, multivariate analysis showed that PAM50 and age were also very substantially related to overall survival. Patients with Her2 positive and basal breast cancer had worse overall survival, and those older than 60 years also had worse overall survival than younger patients

and low UTP23 expression and found 980 differentially expressed genes (DEGs, |log2(FC)|\u0026gt;1, p.adj\u0026lt;0.05), of which 675 genes were significantly upregulated while 305 genes were significantly downregulated. A volcano plot illustrates the DEGs\u0026apos; expression profiles (Fig.4A). Additionally, we analyzed the co-expressed genes of UTP23, in which RAD21 was the most associated gene with UTP23 expression (Fig.4B), and it has been previously shown to be associated with poor prognosis in breast cancer, which adds to the evidence that UTP23 may be associated with poor prognosis in breast cancer\u003csup\u003e[21]\u003c/sup\u003e. In the analysis of DEGs enriched in \u0026nbsp;GO analysis and KEGG pathways, we found that the biological process in which UTP23 most likely to be involved included humoral immune respond、defense response to bacterium、antimicrobial humoral response, and the molecular function it was most likely to affect were endopeptidase inhibitor activity、hormone activity、receptor ligand activity and the cellular component it was most likely to affect were nucleosome、high-density lipoprotein particle、cornified envelope (Fig.4C). Genes associated with each signaling pathway were plotted in Fig.4D. The top 6 GO items and KEGG objects enriched for DEGs are shown in Fig.4E and Fig.4F, respectively. We also performed a GSEA analysis and found that the top 9 data sets with the most significant relationship with UTP23 were signaling by Rho GTPases, M phase, cell cycle checkpoints, neuronal system, deubiquitination, DNA repair, signaling by wnt, transmission across chemical synapses, chromatin-modifying enzymes (Table3, Fig.5). Furthermore, we draw UTP23-interaction proteins in the BRCA tissue network by using the STRING database (Fig.6A) and showed their co-expression scores with UTP23 (Fig.6B).\u003c/p\u003e\n\u003cp\u003e\u003cstrong\u003eTable 3\u0026nbsp;\u003c/strong\u003eReactome pathway enriched in high- and low-risk groups by using GESA.\u003c/p\u003e\n\u003ctable

For those who are fighting breast cancer, this is crucial. In addition, through Kalan-Meier analysis, we found that poor patient outcomes were associated with high UTP23 expression in breast cancer, and UTP23 was more significantly associated with poor patient prognosis in the early stage of the disease, suggesting its potential as a diagnostic and prognostic indicator. In other words, it is possible to dramatically increase the early diagnosis rate of breast cancer by identifying UTP23 expression in the early stages of the disease.

UTP23 (UTP23 Small Subunit Processome Component) is a nucleolar protein that is essential for ribosome production. As we all know, disruption of ribosome structure and function results in improper protein function, affecting the body's normal physiological processes and promoting cancer growth. However, little research has shown a connection between UTP23 and cancer.\u003c/p\u003e\u003ch2\u003eMethods\u003c/h2\u003e \u003cp\u003eWe analyzed the mRNA expression of UTP23 in normal tissue and breast cancer using The Cancer Genome Atlas (TCGA) database and Gene Expression Omnibus (GEO) database, and the protein expression of UTP23 using The Human Protein Atlas (HPA) database. Next, we examined the relationship between UTP23 high expression and Overall Survival (OS) using Kaplan-Meier Plotters and enriched 980 differentially expressed genes in UTP23 high and low expression samples using GO/KEGG and GSEA to identify potential biological functions of UTP23 and signaling pathways that it might influence. Finally, we also investigated the relationship between UTP23 and immune infiltration and examined the effect of UTP23 on the proliferation of human breast cancer cell lines by knocking down UTP23.\u003c/p\u003e\u003ch2\u003eResults\u003c/h2\u003e \u003cp\u003eWe found that UTP23 levels in breast cancer patient samples were noticeably greater than those in healthy individuals and that high UTP23 levels were strongly linked with poor prognoses (\u003cem\u003eP\u003c/em\u003e\u0026thinsp;=\u0026thinsp;0.008). Functional enrichment analysis revealed that UTP23 expression was connected to the humoral immune response. Besides, UTP23 expression was found to be positively correlated with immune cell infiltration. Furthermore, UTP23 knockdown has been shown to inhibit the proliferation of human breast cancer cells MDA-MB-231 and HCC-1806.\u003c/p\u003e\u003ch2\u003eConclusion\u003c/h2\u003e \u003cp\u003eTaken together, our study demonstrated that UTP23 is a promising target in detecting and treating breast cancer and is intimately linked to immune infiltration.\u003c/p\u003e","manuscriptTitle":"UTP23 is a promising prognostic biomarker and is associated with immune infiltration in breast cancer","msid":"","msnumber":"","nonDraftVersions":[{"code":2,"date":"2022-10-12 14:24:01","doi":"10.21203/rs.3.rs-2040046/v2","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}},{"code":1,"date":"2022-09-09 18:58:02","doi":"10.21203/rs.3.rs-2040046/v1","editorialEvents":[{"type":"communityComments","content":0}],"status":"published","journal":{"display":true,"email":"[email protected]","identity":"researchsquare","isNatureJournal":false,"hasQc":true,"allowDirectSubmit":true,"externalIdentity":"","sideBox":"","snPcode":"","submissionUrl":"/submission","title":"Research Square","twitterHandle":"researchsquare","acdcEnabled":true,"dfaEnabled":false,"editorialSystem":"","reportingPortfolio":"","inReviewEnabled":false,"inReviewRevisionsEnabled":true}}],"origin":"","ownerIdentity":"d51b2bfe-1445-4f58-857d-430f21235e58","owner":[],"postedDate":"October 12th, 2022","published":true,"recentEditorialEvents":[],"rejectedJournal":[],"revision":"","amendment":"","status":"posted","subjectAreas":[],"tags":[],"updatedAt":"2022-12-23T08:44:29+00:00","versionOfRecord":[],"versionCreatedAt":"2022-10-12 14:24:01","video":"","vorDoi":"","vorDoiUrl":"","workflowStages":[]},"version":"v2","identity":"rs-2040046","journalConfig":"researchsquare"},"__N_SSP":true},"page":"/article/[identity]/[[...version]]","query":{"redirect":"/article/rs-2040046","identity":"rs-2040046","version":["v2"]},"buildId":"cBFmMYwuxLRRLfASyISRj","isFallback":false,"isExperimentalCompile":false,"dynamicIds":[84888],"gssp":true,"scriptLoader":[]}
