GABAA receptors; Isoflurane sensitivity; Median effective dose; Mice; SNP

GABAA receptors are chloride channels in the brain that are activated by binding with g-aminobutyric acid (GABA). The cDNA sequences of GABAA receptor subunits from two strains of mice with different sensitivities to isoflurane were compared to identify nucleotide mutations. Included 80 mice from two strains with different sensitivities to isoflurane on C57BL/6 ... more

Amazon; Buffaloes; Exon 1; Melatonin; Reproduction characteristics; SNP

The objective of this study was to sequence part of the exon 1 in the melatonin receptor 1A gene (MTRN1A) in buffaloes to detect a novel polymorphism with which to associate reproductive characteristics, such as age at first birth and the interval between births, in buffaloes from the northeastern region of the State of Pará (Brazil). Buffalo hair samples (77) were collected from ... more

LHCGR isoforms; Reproduction; Zebu

The aim of this study was to screen for variability in the luteinizing hormone/choriogonadotropin receptor (LHCGR) and to determine the occurrence of LHCGR mRNA isoforms in two dairy breeds of cattle. Granulosa cells from dominant ovarian follicles were recovered from 16 Gir and 16 Holstein cows, and total RNA was extracted. Complementary DNA was synthesized and PCR was ... more

Nuclear factor kappa B; Repeated implantation failure; Single nucleotide polymorphism; SNP

Despite more than a century of intensive study, the mechanisms of successful pregnancy remain unclear. Recent research suggests that NF-κB (nuclear factor kappa B) plays an important role in embryo implantation. In the current study, we aimed to identify SNPs that contribute to genetic susceptibility for recurrent implantation failure (RIF). Thus, we examined the potential associations ... more

Buffalo; Haplotype; MC4R gene; Milk production; SNP

Melanocortin-4 receptor (MC4R) is associated with feed intake, growth, fatness, and carcass composition in many domestic animals. The aim of this study was to evaluate the association of single nucleotide polymorphisms (SNPs) in MC4R with milk production traits in water buffalo. Eight SNPs were identified by direct polymerase chain reaction sequencing of samples from 18 ... more

Bovine respiratory disease; Feedlot; Finishing; SNP

The objective of the present study was to evaluate single nucleotide polymorphisms (SNPs) located in two quantitative trait locus (QTL) regions (BTA 6 and BTA 20) that are associated with bovine respiratory disease (BRD). A population of 323 crossbred steers sired by five purebred sire breeds during 2010-2013 (Angus, Braford, Braunvieh, Charolais, and Simmental) were evaluated for BRD ... more

Blanco Orejinegro; Creole cattle; Growth traits; Romosinuano; SNP

Colombian creole cattle have important adaptation traits related to heat tolerance and reproductive and productive efficiency. Romosinuano (ROMO) and Blanco Orejinegro (BON) are the most common breeds used by Colombian cattle breeders. Growth traits are of prime importance in these animals, which are mainly raised for beef production. Genes encoding growth hormone, growth hormone receptor ... more

Buffalo; Genotype; Milk; PCR-SSCP; SNP

Water buffaloes (Bubalus bubalis) are quite well adapted to climatic conditions in the Amazon, and in this biome, they are noted for the considerable amount of meat and milk they produce and how hard they are able to work. Because of a lack of research dedicated to improving the rearing of buffaloes in the Amazon, the objective of this study was to genetically characterize the ... more
