Prognostic and clinico-pathological significance of BIN1 in breast cancer

Bridging integrator 1 (BIN1) is a potential tumor suppressor that behaves as silent or misplaced in breast, prostate, skin, lung, and colon cancers. Previous studies noted decreased BIN1 expression in breast cancer (BC). Despite this, BIN1's role in breast cancer is not well understood and remains to be elucidated. Here, we computationally analyzed BIN1 expression and its prognostic role in BC using various databases. Specifically, we found a down-regulated expression profile for the BIN1 gene in different BC subtypes using Oncomine, TCGA, and bcGenExMiner v4.2 web. The expression of BIN1 was found to be associated with various clinico-pathological conditions including estrogen receptor (ER), progesterone receptor (PR) basal-like subtype, and triple-negative breast cancer (TNBC) based on analysis of the bcGenExMiner v4.2…
