N2 - Normally, in human cells, both DNA single- strand breaks (SSBs) and double-strand breaks (DSBs) arising due to exogenous and endogenous DNA damaging agents, are efficiently repaired by base excision repair (BER) and several DSB repair pathways, correspondingly. However, mutations in genes involved in DNA repair or extensive DNA damage caused by exogenous or endogenous mutagens may lead to the accumulation of unrepaired DNA strand breaks (SBs). Accumulation of the persistent SBs results in genomic instability and may lead to many human diseases including cancer. Unlike BER deficiency, that causes downregulation of NHEJ genes and initiates cell death, the knockdown of XRCC4, key NHEJ gene has a less dramatic effect on the expression of BER genes.
