Deskripsi

The PI(3,4)P2 4-phosphatase, INPP4B, functions as a tumour suppressor in triple negative breast cancer. Here, the authors show that INPP4B enhances proliferation and growth of PIK3CA-mutant ER+ breast cancers by promoting PI3Kα-dependent late endosome formation and trafficking that leads to the activation of Wnt/β-catenin signalling.
