PDLIM5 and cancer: The proteins expressed only in the DMEM group were PDLIM5 (proteins phosphorylated by AMPK activation that suppress cell migration [46]), PDLIM7 (a key protein of scaffolds for the formation of multiprotein complexes [47]), Integrin alpha 5 (ITGA5), ASS1 (an enzyme involved in the clearance of nitrogenous waste via the urea cycle and de novo arginine biosynthesis [48]), FHL1 (inhibits the growth of cancer cells via G1/S cell cycle arrest [49]), and voltage-dependent anion channel 3 (VDAC3).
