GADD45GIP1 and leukemia: CRIF1 siRNA administration in Jurkat cells also reversed BMSCs co-culture induced G0/G1 cell arrest, showing as a decrease in G0/G1 cell population (25.89±2.71%, p<0.05) and an increase in G2/M cells (21.51±3.45%, p<0.05), indicating that depletion of CRIF1 promoting the cell cycle progress in the leukemia cells.
