Gene expression profiles of some prognostic markers in a human breast cell line (MCF7) exposed to Curcumin nanoparticles and nanocapsules

1. ABSTRACT Introduction Worldwide, cancer is a significant public health problem. Curcumin exhibits anti-inflammatory, antiproliferative, and anticancer properties when used in medicine. Investigated study for Curcumin’s chemopreventive mechanism against human malignancies, this research examined the cellular and molecular alterations generated by curcumin modified compound in breast cancer (MCF-7) cell lines. Oncogenic EGFR and VEGFR2 mutations lead to the formation, invasion, and maintenance of malignant phenotypes in humans, including breast cancer. Studied prognostic markers such as C-myc and Ki67 in breast cancer, and the apoptotic gene as Caspase-3 have been done. Aim of the work The purpose of this study is to determine the therapeutic efficacy of curcumin nanoparticles and nanocapsules in breast cancer cell lines (MCF7). Materials and methods We used real-time PCR to assess the expression of the C-myc, Ki67, EGFR, VEGFR2, and Caspase-3 genes in MCF7 cells treated with Curcumin nanoparticles and nanocapsules. Results Curcumin nanoparticles and nanocapsules boosted apoptotic cell populations considerably regardless of the nanotechnology used. Additionally, the mRNA expression analysis results indicated that the mechanism activated by curcumin nanocapsules involved the upregulation of the oncogenes EGFR and VEGFR2. In comparison to curcumin nanoparticles, curcumin nanocapsules significantly reduced the expression of Ki67 and c-myc mRNAs in breast cancer cells. The mRNA expression study revealed that curcumin nanocapsules produce an increase in the apoptotic Caspase-3 gene production compared to cells treated with curcumin nanoparticles. Conclusion This work demonstrates that curcumin nanoparticles created using a novel mechanical process can be employed successfully as an anticancer agent. These findings add to our understanding of the molecular mechanisms behind curcumin nanocapsules’ anticancer activity in breast cancer.
