"PIP5K1alpha was associated with poor patient outcome in triple-negative BC. It increased expression of pSer-473 AKT and invasiveness of triple-negative MDA-MB-231 cells. Inhibition reduced expression of pSer-473 AKT and its downstream effectors in xenograft tumors. In ER(+) cancer cells PIP5K1alpha acted on pSer-473 AKT and was in complexes with VEGFR2 serving as co-factor of ER-alpha to regulate activities of targe..."xsd:string
