Abstract Background Fat deposition is an important economic consideration in pig production. The amount of fat pigs seriously affects production efficiency, quality, and reproductive performance, while also affecting consumers’ choice pork. Weighted gene co-expression network analysis (WGCNA) effective genetic studies. Therefore, this study aimed to identify modules that co-express genes associ...

Animal breeders have made widespread use of assisted reproductive technologies to accelerate genetic improvement programs aimed at obtaining more, better and cheaper food products. Selection approaches have traditionally focused on Mendel's laws of inheritance using parental phenotypic characteristics and quantitative genetics approaches to choose the best parents for the next generation, regar...

of loss of function of paternal and maternal allele-specific genes, respectively (Dittrich et al., 1996). Many imprinted genes here, including SNRPN, are unmethylated on the paternal chromosome but methylated on the maternal chromosome. Mutations within the SNRPN exon 1 region cause PWS, and those that occur further upstream and affect certain RNA (BD) transcripts cause AS. The imprinting cente...

The effects of different dietary energy levels [100 and 170% for maintenance (M) and high energy (1.7M), respectively] on metabolic, endocrine, and reproductive parameters were evaluated in nonlactating Bos indicus (Gir; n=14) and Bos taurus (Holstein; n=14) cows submitted to ultrasound-guided ovum pick-up followed by in vitro embryo production. The oocyte donor cows were housed in a tiestall s...

Insulin-like growth factor II (IGF-II) and phosphomannosylated glycoproteins bind to distinct sites on the same receptor, the IGF-II/mannose 6-phosphate receptor (IGF2R). Analysis of truncated receptors (minireceptors) has been used to map the IGF-II binding site within the receptor's extracytoplasmic domain, which consists of 15 homologous repeats. A minireceptor consisting of repeat 11 contai...
