| Popis: | Vomeronasal 1 receptors (V1R) are a family of receptors for intraspecies chemosignals, including pheromones, and are expressed in the olfactory epithelium (OE) and vomeronasal organ (VO). Even in the well-studied rodents, it is unclear which members of the V1R family cause sexual polymorphisms, as there are numerous genes and it is difficult to quantify their expressions individually. Bovine species carry only 34 V1R homologs, and the OE and VOs are large enough to sample. Here, V1R expression was quantified in the OE and VOs of individual bovines. Based on the 34 gene sequences, we obtained a molecular dendrogram consisting of four clusters and six independent branches. Semi-quantitative RT-PCR was used to obtain gene expression profiles in the VOs and OE of 5 Japanese Black bulls, 5 steers, 7 estrous heifers and 6 early luteal-phase heifers. Ten genes showed significant between-group differences, and 22 showed high expression in VOs than in OE. The bulls showed higher expression of one gene more in OE and another in VOs (both P |
