Imatinib metylase is the first choice treatment for BCR/ABL positive chronic myelogenous leukemia (CML). However, as some CML patients develop resistance to imatinib therapy, there is a significant interest in development of alternative treatment strategies, such as identifying targets other than BCR/ABL that may participate in CML. Previously, we demonstrated strong PCNA up-regulation in CML patients. To further study its role in CML pathogenesis, we performed silencing of PCNA expression followed by array experiments. PCNA inhibition led to down-regulation of CDK1, CDK4, PLK1, ERK3, JNK1, STAT5, and several inhibitors of apoptosis (DAXX, Mdm2, survivin). The following genes were up-regulated: CDK inhibitors p21 and p19-INK4D, pro-apoptotic FAST kinase, fibronectin, etc. However, as PCNA affects cell growth in naturally proliferating cells as well as in cancerous cells, it seems to act a secondary role relating to proliferation activity of leukemic cells.
