General Information

General Information Comment Organism
malfunction downregulation of PI3K-C2beta in breast cancer cell lines reduces colony formation, induces cell cycle arrest and inhibits tumor growth, in particular in an estrogen-dependent in vivo xenograft. PI3K-C2beta inhibits breast cancer cell invasion in vitro and breast cancer metastasis in vivo Homo sapiens
physiological function class II phosphoinositide 3-kinase C2beta regulates a novel signaling pathway involved in breast cancer progression. Isozyme PI3K-C2beta regulates breast cancer cell growth in vitro and in vivo, PI3K-C2beta expression in breast tissues is correlated with the proliferative status of the tumor. Analsis of the mechanism of the PI3K-C2beta-dependent regulation of cell cycle progression and cell growth revealed that PI3K-C2beta regulates cyclin B1 protein levels through modulation of microRNA miR-449a levels. PI3K-C2beta may represent a key molecular switch that regulates a rate-limiting step in breast tumor progression and therefore it may be targeted to limit breast cancer spread. PI3K-C2beta regulates cyclin B1 expression through modulation of miR-449a, miR-449a levels are downregulated in primary human breast cancer samples, and cyclin B1/miR-449a expression through modulation of LEF1/beta catenin pathway in MDA-MB-231 cells.
