AKT1 and neoplasm: Phosphatase and tensin homolog (PTEN) negatively regulate intracellular levels of phosphatidylinositol-3,4,5-trisphosphate (PIP3) in cells and functions as a tumor suppressor by negatively regulating protein kinase B (PKB/AKT) signaling pathway (Worby and Dixon, 2014; Yehia et al., 2020).
