Focal Adhesion Kinase as a Potential Target in AML and MDS.

ABSTRACT: Although overexpression/activation of focal adhesion kinase (FAK) is widely known in solid tumors to control cell growth, survival, invasion, metastasis, gene expression, and stem cell self-renewal, its expression and function in myeloid leukemia are not well investigated. Using reverse-phase protein arrays in large cohorts of newly diagnosed acute myeloid leukemia (AML) and myeloid dysplastic syndrome (MDS) samples, we found that high FAK expression was associated with unfavorable cytogenetics (P = 2 × 10^-4) and relapse (P = 0.02) in AML. FAK expression was significantly lower in patients with FLT3-ITD (P = 0.0024) or RAS (P = 0.05) mutations and strongly correlated with p-SRC and integrinβ3 levels. FAK protein levels were significantly
