Recent studies have shown that RNase H2 function is also needed for successful DNA repair through NHEJ events where DNA pol ยต uses ribonucleotides during the gap filling stage. Mammalian RNase H2 is composed of three subunits, RNASEH2A, RNASEH2B and RNASEH2C. There have been studies suggesting changes in expression of these genes in various cancers of breast, prostate, colon, liver, and kidney. In this study, we have investigated the functional role of RNASEH2A and RNASEH2B in leukemic T-cells, MOLT4 and Jurkat. shRNA mediated knockdown of RNASEH2A/ RNASEH2B expression led to reduced cell survival and increase in apoptotic cell population. Importantly, knockdown of RNASEH2A or RNASEH2B, led to cell cycle arrest at S phase and increased number of 53BP1 foci due to abrogation of NHEJ. Interestingly, RNASEH2A or RNASEH2B depleted cells showed significantly retarded DSB repair kinetics compared to scrambled shRNA control, when exposed to ionizing radiation suggesting that NHEJ is abrogated due to loss of RNASEH2 activity in T-ALL cells. Thus, we uncover the importance of RNase H2 function in leukemic cells and suggest that it can be targeted for cancer therapy."xsd:string |
