Glucokinase (GCK) plays a key role in glucose homeostasis. Gestational diabetes mellitus increases the risk of gestational complications in pregnant women and fetuses. We screened for mutations in coding and flanking regions of the GCK gene in pregnant women with or without gestational diabetes in a Brazilian population. A sam.. Read More»

Research has shown that genetic polymorphisms in biotransformation enzymes, such as CYP1A1 and GSTM1, are related to a greater or lesser susceptibility to various cancers. We made an analysis of CYP1A1m1 SNP and GSTM1 null genotypes in a family group (71 members) related by consanguinity who had an unusually high incidence of .. Read More»

High-altitude pulmonary edema (HAPE) is a life-threatening condition caused by acute exposure to high altitude. Accumulating evidence suggests that genetic factors play an important role in the etiology of HAPE. However, conclusions from association studies have been hindered by limited sample size due to the rareness of this disease. It is known that mitoch.. Read More»

The aim of this study was to evaluate different methods used in genomic selection, and to verify those that select a higher proportion of individuals with superior genotypes. Thus, F2 populations of different sizes were simulated (100, 200, 500, and 1000 individuals) with 10 replications each. These consisted of 10 linkage groups (LG) of 100 cM each, cont.. Read More»

Periostin, also called osteoblast-specific factor 2, is an important regulator of bone, cardiac development, and wound healing. A recent study revealed that periostin plays an important role in tumor development and is upregulated in a wide variety of cancers. However, little is known about periostin in swine. Therefore, the cDNA sequence of the porcine p.. Read More»

The mannan-binding lectin gene (MBL) participates as an opsonin in the innate immune system of mammals, and single nucleotide polymorphisms (SNPs) in MBL cause various immune dysfunctions. In this study, we detected SNPs in MBL2 at exon 1 using polymerase chain reaction single-strand conformation polymorphism analysis and DNA sequencing techniques in 825 Chi.. Read More»

The peroxisome proliferator-activated receptor gamma (PPAR-Ã?³) is a key molecule in adipocyte differentitation; it transactivates multiple target genes in lipid metabolic pathways. Using PCR-SSCP and DNA sequencing, we evaluated a potential association of an SNP (72472 Gï¹¥T in exon7) of the bovine PPAR-Ã?³gene with carcass and meat quality traits in 6.. Read More»

Diabetic nephropathy is the leading cause of end-stage kidney disease in the world. Many single nucleotide polymorphisms (SNPs) have been associated with diabetic nephropathy. SNPs at the 4.1 protein ezrin, radixin, moesin domain 3 (FRMD3) and cysteinyl t-RNA synthetase (CARS) genes have a well-established relationship with diabetic nephropathy. However, .. Read More»

The peroxisome proliferators-activated receptor-γ coactivator-1α (PGC-1α) is a candidate gene for meat quality traits because of its prominent role in muscle fiber type switching and determination. We investigated the effects of the PGC-1α gene on chicken skeletal muscle fiber type switching and on othe.. Read More»
