PTK2 and AL amyloidosis: AA showed inhibition of cell proliferation and growth by arresting the progression of cell cycle in a time- and concentration-dependent manner and led to G2/M phase and reduced expression of focal adhesion kinase (FAK) and phosphorylated-FAK mediated signal transduction in multiple myeloma cells; RPMI 8226 (Zhang H. R. et al., 2013; Zhang J. et al., 2013).
