Decreased myo-inositol, phosphatidylinositol 4,5-bisphosphate (PIP2) and phosphatidylinositol 3,4,5-trisphosphate (PIP3) contents and AKT phosphorylation level were observed after SMIT1 silencing, yet increased after SMIT1 overexpression in DLBCL cells. The gene discussed is AKT1; the disease is diffuse large B-cell lymphoma.
