Homologous recombination is a largely error-free DNA repair mechanism conserved across all domains of life and is essential for the maintenance of genome integrity. Not only are the mutations in homologous recombination repair genes probable cancer drivers, some also cause genetic disorders. In particular, mutations in the Bloom (BLM) helicase cause Bloom Syndrome, a rare autosomal recessive disorder characterized by increased sister chromatid exchanges and predisposition to a variety of cancers.

Upon infection, human papillomavirus (HPV) manipulates host cell gene expression to create an environment that is supportive of a productive and persistent infection. The virus-induced changes to the host cell's transcriptome are thought to contribute to carcinogenesis. Here, we show by RNA-sequencing that oncogenic HPV18 episome replication in primary human foreskin keratinocytes (HFKs) drives host transcriptional changes that are consistent between multiple HFK donors.

Identification of chromosomal abnormalities is an important issue in animal breeding and veterinary medicine. Routine cytogenetic diagnosis of domestic animals began in the 1960s with the aim of identifying carriers of centric fusion between chromosome 1 and 29 in cattle. In the 1970s, chromosome banding techniques were introduced, and in the 1980s, the first cytogenomic techniques, based on the development of locus- and chromosome-specific probes, were used.

Its medical importance has made it a subject of numerous efforts to understand their biology. One such effort, was the development of a high-quality reference genome (AaegL5).

Upon mismatch detection, MSH complexes recruit the PCNA- stimulated endonuclease Mlh1-Pms1/PMS2 (yeast/human), which nicks the DNA to allow downstream proteins to remove the mismatch. Past work has shown that although Mlh1-Pms1 is an ATPase and this activity is important , ATP is not required to nick DNA.
