Ionophore Antibiotics Inhibit Type II Feline Coronavirus Proliferation In Vitro.

Feline coronaviruses (FCoVs) infect cats worldwide and cause severe systemic diseases, such as feline infectious peritonitis (FIP). FIP has a high mortality rate, and drugs approved by the Food and Drug Administration have been ineffective for the treatment of FIP. Investigating host factors and the functions required for FCoV replication is necessary to develop effective drugs for the treatment of FIP.

The number of glutamines in the N-terminal of the canine androgen receptor affects signalling intensities.

Most male dogs are castrated at young ages, making them easy to rear following androgen deprivation. Although the incidence of canine prostate cancer is low, several patients have resistance to androgen therapy and poor clinical prognosis. These outcomes are similar to those of end-stage human androgen-independent prostate cancer.

Novel canine isocitrate dehydrogenase 1 mutation Y208C attenuates dimerization ability.

Isocitrate dehydrogenase 1 (IDH1) mutations are common in gliomas, acute myeloid leukemia, and chondrosarcoma. The mutation 'hotspot' is a single arginine residue, R132. The R132H mutant of IDH1 produces the 2-hydroxyglutarate (2-HG) carcinogen from α-ketoglutarate (α-KG).

The canine RAD51 mutation leads to the attenuation of interaction with PALB2.

RAD51 forms a complex with BRCA2 and plays a central role in the DNA damage response pathway that is associated with homologous recombination. The structures of RAD51 and its homologues are highly conserved from prokaryotes to higher eukaryotes. Although a large number of BRCA2 mutations have been reported, there are only a few reports on the mutations of RAD51, which have been shown in humans and dogs.
