Triple Negative Breast Cancer Huaier Aqueous Proliferation Apoptosis In vivo Figures Figure 1 Figure 2 Figure 3 Figure 4 Figure 5 Figure 6 Introduction The survival rate of breast cancer patients has grown dramatically as early identification of the disease and the development of tailored treatment. However, breast cancer remains the top cause of cancer deaths among women globally[1]. TNBC is a complex and heterogeneous malignancy that lacks ER, PR and HER2 gene amplification, making it unsuitable for endocrine and targeted treatment[2]. Compared with other forms of cancer, the biological features of TNBC have a greater risk of invasiveness and recurrence[3]. TNBC patients have a considerably elevated risk of metastasis within 5 years of diagnosis[4], and around 46% of TNBC patients will have distant metastases[5]. Women with TNBC had a greater rate of pathological complete remission(PCR) after neoadjuvant chemotherapy, as well as longer-lasting outcomes and a lower recurrence rate[6]. However, when the illness persists after therapy, the overall survival rate of TNBC patients is lowered[7]. Adjuvant chemotherapy of traditional Chinese medicine(TCM) has become a systemic treatment method for TNBC patients. Huaier Aqueous has been widely used as a traditional Chinese herbal medicine for many diseases for thousands of years[8, 9]. More and more studies have demonstrated that Huaier Aqueous can induce apoptosis, autophagy[10], immunoregulation[11]. This biological mechanism varies with tumor types, so it has generated many scholars to examine the molecular basis of Huaier Aqueous anti-cancer[12]. Huaier Aqueous assume a vital part in the adjuvant medicine about TNBC patients. To particular, Huaier Aqueous inhibits TNBC stem cell-like characteristics by inactivating the ERα-36 signaling pathway[13]. Chen Y checked that Huaier Aqueous repressed the burgeoning about TNBC in BALB/c-nu mice in vivo experiments[14]. However, Huaier Aqueous possesses multiple targets, and its anti-tumor mechanism is not thoroughly understood. Therefore, this experiment analyzed the molecular targets of the Huaier Aqueous anti-tumor process. Materials And Methods Huaier Aqueous acquired from Qidong GAITISNLI(Jiangsu, China).

Results 3.1 Huaier Aqueous and Adriamycin inhibit MDA-MB-231 cells proliferation and promote cell apoptosis The results of CCK-8 experiments showed that MDA-MB-231 cell survival rates decreased in a time-dose-dependent way. Huaier Aqueous had IC 50 values of 8.391±0.398mg/ml and 5.245±0.519mg/ml in MDA-MB-231 cells after 24 and 48 hours. Furthermore, the IC 50 of Adriamycin on MDA-MB-231 cells after 24 hours and 48 hours was 0.480±0.319ug/ml and 0.343±0.465ug/ml(Fig1a and b). Flow cytometry showed that 0.5, 1, 2, 4, 6, 8 mg/ml Huaier Aqueous early (2.69%, 2.12%, 3.27%, 4.38%, 10.33%, 14.06% VS 2.08%), late (1.87%, 3.30%, 3.70%, 3.78%, 13.92%, 21.11% VS 1.47%) and total (4.56%, 5.42%, 6.97%, 8.16%, 24.25%, 35.17% VS 3.55%) apoptosis rates were the same as those of the control group(P<0.05) (Fig1c). 0.1, 0.2, 0.3, 0.4, 0.5ug/ml Adriamycin early (4.74%, 5.18%, 5.60%, 6.30%, 6.50% VS 2.73%), late (3.71%, 4.17%, 4.61%, 4.50%, 5.93% VS 1.30%) and total (8.45%, 9.35%, 10.21%, 10.80%, 12.43% VS 4.03%) apoptosis rates(P<0.05) (shown in Fig. 1. d). Western blot investigation demonstrated that examination with those control group, distinctive focuses from claiming Huaier Aqueous and Adriamycin down-regulated the statement for anti-apoptotic protein Bcl-2, same time those statement of pro-apoptotic proteins Bax and Caspase9 were up-regulated(Fig1e and f). Based on the above experimental results, it was determined that the low, medium and high concentrations of Huaier Aqueous were 0.5mg/ml, 2mg/ml, 6mg/ml, and the concentration of Adriamycin was 0.3ug/ml. 3. 2 Huaier Aqueous inhibits PI3K/AKT/mTOR signaling pathway in MDA-MB-231 cells In order to examine the role of PI3K/AKT/m TOR pathway in TNBC cells. Western blot results shows that as the concentration of Huaier Aqueous increased, the expression of pathway-related proteins p-PI3K and p-AKT1 was down-regulated and 6 mg/ml Huaier Aqueous can significantly inhibit the expression of p-PI3K and p-AKT1 (Fig2a). In comparison to the Huaier Aqueous 6mg/ml group, Western blot findings revealed that 30uM 740Y-P and 5mM SC79 up-regulated the expression of p-PI3K, p-AKT1, and mTOR protein, with significant differences(P<0.05) (Fig2b). 3.3 Huaier Aqueous inhibits the migration and invasion of MDA-MB-231 cells The Wound healing test results show that a academic noticeable differences between the blank control group and each experimental groups (P<0.05) (Fig3a). The Transwell test results show , blank control group:100±5.315, 0.3ug/ml Adriamycin group: 32.131±5.020, 0.5mg/ml Huaier Aqueous group: 82.641±3.099, 2mg/ml Huaier Aqueous group: 58.475±3.684, 6mg/ml Huaier Aqueous group: 13.547±1.898 (P<0.05) (Fig3b). The 48-hour wound healing percentages of MDA-MB-231 cells treated with 30uM 740Y-P and 5mM SC79 are 37.88±1.60 and 31.53±2.06 respectively(Fig3c). There was a academic noticeable differences(P<0.05) with the wound healing percentage of 6mg/ml Huaier Aqueous -8.91±0.37. Transwell test results revealed that the percentages of the number of cells passing through the basement membrane in each group(Fig3d) were: blank control group: 100±2.16, 6mg/ml Huaier Aqueous group: 16.30±3.27, 30uM 740Y-P group: 135.50±8.91, 30uM 740Y-P+6mg/ml Huaier Aqueous group: 75.59±5.78, 5mM SC79 group: 126.20±4.32, 5mM SC79+6mg/ml Huaier Aqueous group: 91.55±8.38(P<0.05). 3.4 Huaier Aqueous blocks the S phase of the MDA-MB-231 cell cycle and promotes its apoptosis MDA-MB-231 expression in the S phase of the cell cycle was determined using flow cytometry. MDA-MB-231 cells in S phase dropped from 47.71% to 32.65%, 17.64%, and 16.07%, compared to the blank control group(P<0.05). The percentage of 0.3ug/ml Adriamycin decreased from 47.71% to 27.57%(P<0.05) (Fig4a). The qPCR results show that Huaier Aqueous demonstrated a concentration-dependent down-regulation of CyclinD1 gene expression when compared to the control group(Fig4b). Western blot results showed that contrasted with the control group, the higher the concentration of Huaier Aqueous, the more pronounced the inhibition of CyclinD1 expression (Fig4c). Flow cytometry shows that 0.5, 2, 6mg/ml Huaier Aqueous early (7.30%, 8.40%, 10.40% VS 3.60%), late (7.30%, 12.00%, 12.60% VS 3.70%) and total (14.60%, 20.40%, 23.00% VS 7.30%) apoptosis rates were academic differences from those of the control group (P<0.05) (Fig4d). The Huaier Aqueous groups effectively inhibited the anti-apoptotic gene Bcl-2 and promoted the expression of the apoptotic genes Bax and Caspase9 when compared to the control group, according to the qPCR results (Fig4e). Different concentrations of Huaier Aqueous decreased the expression of anti-apoptotic protein Bcl-2 and increased the expression of pro-apoptotic proteins Bax and Caspase9 in MDA-MB-21 cells, according to Western blot results (Fig4f). 3.5 Huaier Aqueous blocked MDA-MB-231 cell cycle and promoted apoptosis by the PI3K/AKT/mTOR pathway Flow cytometry results showed that MDA-MB-231 cells treated with 740Y-P and SC79, the proportion of MDA-MB-231 cells in S phase rose from 28.85% to 49.17% and 34.18%(P<0.05). Compared with 6mg/ml Huaier Aqueous, the 740Y-P+6mg/ml Huaier Aqueous group rose to 26.27%, and the SC79+6mg/ml Huaier group rose to 25.55%(P<0.05) (Fig5a). qPCR method detect that 30uM 740Y-P, 5mM SC79 stimulated the expression of CyclinD1 and comparison with 6mg/ml Huaier Aqueous(P<0.05) (Fig5b). The 740Y-P group and SC79 group up-regulated the expression of protein CyclinD1. The 30uM 740Y-P+6mg/ml Huaier Aqueous and 5mM SC79+6mg/ml Huaier Aqueous groups increased CyclinD1 expression, which was academic noticeable differences from the Huaier Aqueous group (P<0.05) (Fig5c). Flow cytometry demonstrated that 30uM 740Y-P, 5mM SC79, 30uM 740Y-P+6mg/ml Huaier Aqueous and 5mM SC79+6mg/ml Huaier Aqueous early (1.57%, 1.47%, 2.19% and 3.09%) late (1.59%, 1.29%, 2.16%, and 3.20%) and total (3.16%, 2.76%, 4.35%, and 6.29%) apoptosis rates were academic noticeable differences from those in the Huaier Aqueous group(P<0.05) (Fig5d). The up-regulation of Bcl-2 gene expression was significantly increased in the 740Y-P and SC79 groups compared to the Huaier Aqueous group, whereas the down-regulation of Bax and Caspase9 genes(P<0.05) (Fig5e). The apoptotic proteins Bax and Caspase9 were downregulated in the 740Y-P and SC79 groups, while the anti-apoptotic protein Bcl-2 was upregulated in the SC79 group. 30uM 740Y-P+6mg/ml Huaier Aqueous group,5mM SC79+6mg/ml Huaier Aqueous group apoptosis proteins Bax and Caspase9 were reduced, while anti-apoptotic protein Bcl-2 was increased(P<0.05) (Fig5f). 3.6 In vivo experiments verify that Huaier Aqueous inhibits PI3K/AKT/mTOR pathway and exerts anti-tumor effect The results show that 6mg/ml Huaier Aqueous can inhibit the growth of tumors, 740Y-P promotes tumor proliferation, 740Y-P+6mg/ml Huaier Aqueous comparison with Huaier Aqueous group, tumor tissues proliferate again(Fig6a). The HE chemical staining demonstrated that Huaier Aqueous causes tumor tissue necrosis, and 740Y-P promotes the proliferation of TNBC tumor tissue (Fig6f). Huaier Aqueous down-regulated the expression of PI3K, mTOR, anti-apoptotic gene Bcl-2, and cell cycle CyclinD1, and up-regulated the expression of pro-apoptotic genes Bax and Caspase9, according to the results of qPCR tests. The 740Y-P group had higher levels of AKT, mTOR, and CyclinD1 expression than the control group (P<0.05) (Fig6b and c). Huaier Aqueous reduces the expression of p-PI3K, p-AKT1, anti-apoptotic protein Bcl-2, and cell cycle CyclinD1 protein, while increasing the expression of pro-apoptotic protein Bax and Caspase9. The 740Y-P+6mg/ml Huaier Aqueous group down-regulated Bax and Caspase9 expression while up-regulating p-PI3K, Bcl-2, and CyclinD1 (P<0.05) (Fig6d,e,g and h). The results of Tunel analyzes demonstrated that the Huaier Aqueous group and the 6mg/ml Huaier Aqueous+740Y-P group significantly promoted tumor tissue apoptosis (P<0.05) (Fig6i). Discussion In subsequent years, Huaier Aqueous has demonstrated to inhibit the proliferation of a variety of cancer cells. Examples involve gastric cancer[15], hepatocellular carcinoma[16], ovarian cancer[17], colorectal cancer[18], and melanoma[19]. However, the anti-tumor mechanism of Huaier Aqueous has not been entirely elucidated. The wound healing and transwell results are consistent with the results of Qi[20], Wang[21], Gao[22], etc., which established that Huaie Aqueous inhibited breast cancer proliferation and migration. The PI3K pathway mediates key cell functions, including growth, proliferation, survival and angiogenesis[23]. Activation of oncogenic mutations is an attractive drug target for many malignant tumors[24]. Mutations in PIK3CA can cause tumor transformation and promote cancer progression. According to sources, PIK3CA mutations account for about 18%, 17% -33% of cervical cancer, 39% of endometrial cancer, and 12% of ovarian cancer[25]. A considerable amount of evidence states that the effects of AKT involve facilitating growth factor-induced cell survival and inhibiting apoptosis. Caspase-9 is the promoter of apoptosis, and it triggers a cascade of caspase family proteins to trigger apoptosis[26]. Bax and Bcl-2 are essential regulators in the PI3K/AKT/mTOR pathway[27]. This study are comparable to those ofss Zhang[9] and Wang[28], which clearly confirms that Huaier Aqueous promotes MDA-MB-231 cell apoptosis by the PI3K/AKT/mTOR signaling pathway. Currently, Cyclin D1 has been identified as a proto-oncogene[29]. The primary function of Cyclin D1 is to enhance cell proliferation. Cyclin D1 overexpression plays a role in promoting diverse types of cancers such as mantle cell lymphoma[30] and head and neck cancer[31]. Cyclin D1 functions in the S phase of the cell cycle. The overexpression of Cyclin D1 can accelerate the transition of cells from G1 phase to S phase, contributing to uncontrolled cell proliferation, while the decrease of Cyclin D1 expression can prompt cells to suppress S phase[32]. Those results shows that TNBC cells regulate proliferation by the PI3K/AKT/mTOR signaling pathway. But the conclusions about cell cycle arrest are not the same. Zhang et al.[9] found that MCF-7 cell cycle block G0/G1 phase was suppressed by Huaier Aqueous treatment, but no changes in MDA-MB-231 cell cycle block were found. Ding et al.[33] Huaier Aqueous prevented G0/G1 phase arrest by down-regulating cell cycle regulatory proteins in MCF-7 and MDA-MB-468 cells. Therefore, the in vivo experiment of Huaier Aqueous treatment of TNBC demands continued verification and confirmation. Conclusion Huaier Aqueous inhibits the proliferation and migration of MDA-MB-231 cells. What's more disrupts the cell cycle on S phase, thereby encouraging cell apoptosis. In addition, Huaier Aqueous inhibits the cell cycle and pushes apoptosisof MDA-MB-231 cells via PI3K/AKT/mTOR pathway.

However, breast cancer remains the top cause of cancer deaths among women globally[1]. TNBC is a complex and heterogeneous malignancy that lacks ER, PR and HER2 gene amplification, making it unsuitable for endocrine and targeted treatment[2]. Compared with other forms of cancer, the biological features of TNBC have a greater risk of invasiveness and recurrence[3]. TNBC patients have a considerably elevated risk of metastasis within 5 years of diagnosis[4], and around 46% of TNBC patients will have distant metastases[5]. Women with TNBC had a greater rate of pathological complete remission(PCR) after neoadjuvant chemotherapy, as well as longer-lasting outcomes and a lower recurrence rate[6]. However, when the illness persists after therapy, the overall survival rate of TNBC patients is lowered[7].\u003c/p\u003e \u003cp\u003eAdjuvant chemotherapy of traditional Chinese medicine(TCM) has become a systemic treatment method for TNBC patients. Huaier Aqueous has been widely used as a traditional Chinese herbal medicine for many diseases for thousands of years[8, 9]. More and more studies have demonstrated that Huaier Aqueous can induce apoptosis, autophagy[10], immunoregulation[11]. This biological mechanism varies with tumor types, so it has generated many scholars to examine the molecular basis of Huaier Aqueous anti-cancer[12]. Huaier Aqueous assume a vital part in the adjuvant medicine about TNBC patients. To particular, Huaier Aqueous inhibits TNBC stem cell-like characteristics by inactivating the ERα-36 signaling pathway[13]. Chen Y checked that Huaier Aqueous repressed the burgeoning about TNBC in BALB/c-nu mice in vivo experiments[14]. However, Huaier Aqueous possesses multiple targets, and its anti-tumor mechanism is not thoroughly understood. Therefore, this experiment analyzed the molecular targets of the Huaier Aqueous anti-tumor process.\u003c/p\u003e"},{"header":"Materials And Methods","content":"\u003cp\u003eHuaier Aqueous acquired from Qidong GAITISNLI(Jiangsu, China).

However, the anti-tumor mechanism of Huaier Aqueous has not been entirely elucidated.

Activation of oncogenic mutations is an attractive drug target for many malignant tumors[24]. Mutations in PIK3CA can cause tumor transformation and promote cancer progression. According to sources, PIK3CA mutations account for about 18%, 17% -33% of cervical cancer, 39% of endometrial cancer, and 12% of ovarian cancer[25]. A considerable amount of evidence states that the effects of AKT involve facilitating growth factor-induced cell survival and inhibiting apoptosis. Caspase-9 is the promoter of apoptosis, and it triggers a cascade of caspase family proteins to trigger apoptosis[26]. Bax and Bcl-2 are essential regulators in the PI3K/AKT/mTOR pathway[27]. This study are comparable to those ofss Zhang[9] and Wang[28], which clearly confirms that Huaier Aqueous promotes MDA-MB-231 cell apoptosis by the PI3K/AKT/mTOR signaling pathway.\u003c/p\u003e \u003cp\u003eCurrently, Cyclin D1 has been identified as a proto-oncogene[29]. The primary function of Cyclin D1 is to enhance cell proliferation. Cyclin D1 overexpression plays a role in promoting diverse types of cancers such as mantle cell lymphoma[30] and head and neck cancer[31]. Cyclin D1 functions in the S phase of the cell cycle. The overexpression of Cyclin D1 can accelerate the transition of cells from G1 phase to S phase, contributing to uncontrolled cell proliferation, while the decrease of Cyclin D1 expression can prompt cells to suppress S phase[32]. Those results shows that TNBC cells regulate proliferation by the PI3K/AKT/mTOR signaling pathway. But the conclusions about cell cycle arrest are not the same. Zhang et al.[9] found that MCF-7 cell cycle block G0/G1 phase was suppressed by Huaier Aqueous treatment, but no changes in MDA-MB-231 cell cycle block were found. Ding et al.[33] Huaier Aqueous prevented G0/G1 phase arrest by down-regulating cell cycle regulatory proteins in MCF-7 and MDA-MB-468 cells.
