Peptides from preselected regions of the herpes simplex virus DNA polymerase were used to generate monospecific antisera to defined regions of the enzyme. The antisera were used to localize the polymerase within the infected cell and to determine the time of synthesis during productive infection. Comparison with a neutralizing polyclonal antiserum was used to show the specificity of the peptide antisera. By using the antisera the stabilities of the DNA polymerase, the alkaline nuclease, and the major DNA-binding protein were determined, and the state of phosphorylation of the DNA polymerase was compared with each of these proteins.

There is an increasing need for biomarkers of senescent cell burden to facilitate the selection of participants for clinical trials. p16 is encoded by the CDKN2A locus, which produces five variant transcripts in humans, two of which encode homologous p16 proteins: p16, encoded by p16_variant 1, and p16ɣ, encoded by p16_variant 5. While distinct quantitative polymerase chain reaction primers can be designed for p16_variant 5, primers for p16_variant 1 also measure p16_variant 5 (p16_variant 1 + 5).

Background: Chronic active Epstein-Barr virus (CAEBV) infection is a rare disease in which the Epstein-Barr virus (EBV) persists and replicates, causing chronic symptoms and fatal complications. The treatment of CAEBV is still evolving. Our case report showed a new therapy for CAEBV.

Cholangiocarcinoma (CCA) is a biliary tract carcinoma that is challenging to treat due to its heterogeneity and limited treatment options. Genetic alterations in DNA damage response (DDR) pathways and homologous recombination (HR) defects are common in CCA. This has prompted interest in the use of ataxia telangiectasia and Rad3-related protein (ATR) and poly(ADP-ribose) polymerase (PARP) inhibitors to treat CCA.

Catalytic subunit of DNA polymerase ζ (REV3), involved in translesion-replication is evolutionarily conserved from yeast and plants to higher eukaryotes. However, a large intermediate domain is inserted in REV3 of humans and mice. The domain has "DUF4683" region, which is significantly similar to human neurite extension and migration factor (NEXMIF).

Background: Progressive external ophthalmoplegia (PEO) is a classic manifestation of mitochondrial disease. However, the link between its genetic characteristics and clinical presentations remains poorly investigated.
Methods: We analysed the clinical, pathological and genetic characteristics of a large cohort of patients with PEO, based on the type of their mtDNA variations.
