Research Abstract

There are two types of cancer associated genomic instabilities, i.e., either microsatellite or chromosomal instabilities, which develop dependent on either proficient or deficient in mismatch repair (MMR) function. Here we found that chromosomal instability is triggered by DNA replication stress-associated lesions in the presence of MMR and that senescence associated risk elevation of both genomic instabilities is ascribed to H2AX diminution during senescing process.
