Abstract

Progesterone (P4) plays a pivotal role in regulating the Cancer progression of various types, including breast Cancer, primarily through its interaction with the P4 receptor (PR). In PR-negative breast Cancer cells, P4 appears to function in mediating Cancer progression, such as cell growth. However, the mechanisms underlying the roles of P4 in PR-negative breast Cancer cells remain incompletely understood. This study aimed to investigate the effects of P4 on cell proliferation, gene expression, and signal transduction in PR-negative MDA-MB-231 breast Cancer cells. P4-activated genes, associated with proliferation in breast Cancer cells, exhibit a stimulating effect on cell growth in PR-negative MDA-MB-231 cells, while demonstrating an inhibitory impact in PR-positive MCF-7 cells. The use of arginine-glycine-aspartate (RGD) peptide successfully blocked P4-induced extracellular signal-regulated kinase 1/2 (ERK1/2) activation, aligning with computational models of P4 binding to Integrin αvβ3. Disrupting Integrin αvβ3 binding with RGD peptide or anti-integrin αvβ3 antibody altered P4-induced expression of proliferative genes and modified P4-induced cell growth in breast Cancer cells. In conclusion, Integrin αvβ3 appears to mediate P4-induced ERK1/2 signal pathway to regulate proliferation via alteration of proliferation-related gene expression in PR-negative breast Cancer cells.
