Alteration of gene expression profile following PPP2R5C knockdown may be associated with proliferation suppression and increased apoptosis of K562 cells

J Hematol Oncol. 2015 Apr 12:8:34. doi: 10.1186/s13045-015-0125-5.

Abstract

We reported that knockdown of PPP2R5C by siRNA led to proliferation inhibition and apoptosis induction in K562 cells. In this study, we further characterized the gene expression profiles after PPP2R5C suppression by microarray analysis. Genes which participate in the MAPK, PI3K/AKT, and JAK/STAT pathways, were mainly altered in the K562 cells. We propose that the mechanism for proliferation inhibition and increased apoptosis of K562 cells following PPP2R5C suppression may be related to the alteration of expression profiles of BRAF, AKT2, AKT3, NFKB2 and STAT3 genes.
