IGF-1; PCR-SSCP; SNP

The IGF-1 gene has been implicated as a candidate gene for the regulation of pig growth traits. We analyzed exons 3 and 4 of IGF-1 gene polymorphisms of the Banna mini-pig (28), the Tibetan mini-pig (30), the Junmu pig (55), and L. Yorkshire species (50) using PCR-SSCP. Three genotypes in exon 3 and 6 genotypes in exon 4 were observed, among which, one single nucleotide polymorphism, ... more

Growth hormone gene; PCR-SSCP; Wistar-Imamichi rat

We successfully cloned the Wistar-Imamichi (WI) rat growth hormone gene (GenBank accession: GQ890681), which contained 5 exons and 4 introns. Using the polymerase chain reaction-single-strand conformation polymorphism (PCR-SSCP) technique, a novel missense substitution single nucleotide polymorphism was identified and tested for Hardy-Weinberg equilibrium with the χ2 test. This ... more

Goat; Growth traits; Myostatin gene (MSTN); PCR-SSCP; Polymorphism

Mutations in the myostatin (MSTN) gene can inactivate its expression and result in a non-functional protein, which leads to dramatic muscularity and a “double-muscling” phenomenon in many species. Using gene sequencing and polymerase chain reaction-single-strand conformation polymorphism methods, polymorphisms of the MSTN gene were investigated as a candidate marker for ... more

ARMS-PCR; Genotyping; mutations; PCR-SSCP; PRNP alleles; Sheep

Anti-scrapie breeding programs have been initiated to screen for scrapie-resistant sheep based on ovine prion protein gene (PRNP) genotypes at codons 136, 154 and 171 in many countries, especially European Union member states. However, investigation of sheep PRNP genotypes is limited in China, despite the large number of sheep breeds. We analyzed 432 sheep of five different breeds from ... more

GFI1B gene; Growth trait; Indigenous Chinese goats; PCR-RFLP; PCR-SSCP

This study aimed to investigate polymorphisms of the eighth exon in the GFI1B gene among three indigenous Chinese goat breeds (QianBei Ma goats, GuiZhou white goats, and GuiZhou black goats). Furthermore, association analysis was conducted between these polymorphisms and growth traits. Polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP), direct DNA ... more

Body measurement traits; Cattle; MyoG; Polymorphisms

Using PCR-SSCP and DNA sequencing technology, we examined the association of single nucleotide polymorphisms (SNPs) in the bovine MyoG gene with body measurement traits in 779 individuals of six native Chinese cattle breeds, namely Luxi, Luxi × Simmental crossbred, Nanyang, Xia’nan, Jiaxian red, and Qinchuan. A novel SNP, T314C, was detected. Allelic frequencies of MyoG- ... more

eNOS; Essential hypertension; Han population; Haplotype; SNPs

Endothelial nitric oxide synthase (eNOS) plays an important role in maintaining blood pressure homeostasis and vascular integrity. Polymorphisms in the eNOS gene have been found to be associated with hypertension in different human populations, including Northern and Southern Chinese Han populations. To examine the relationship of three eNOS gene polymorphisms, T-786C ( ... more

Cattle; CYP21; Genotype-phenotype association; IGF2; SNPs

We analyzed two single nucleotide polymorphisms (SNPs) of the IGF2 and CYP21 genes in Nellore cattle participating in the Brazilian Animal Breeding Program. The SNPs were found in exon 6 of the IGF2 (insulin-like growth factor 2) gene (RFLP/MboII) as well as in the promoter region of the CYP21 (steroid 21-hydroxylase) gene (RFLP/HpaII) ... more

CART gene; Goats; Microsatellites; Reproduction traits; SNPs

Polymorphisms of the CART gene were investigated by PCR-single-strand conformation polymorphism analysis in 540 samples from 10 goat breeds. Ten novel single-nucleotide polymorphisms as well as three microsatellites were detected; a mutation, 77T→C, led to an amino acid change (Leu→Ser). Associations between polymorphic loci and reproductive traits were analyzed in Chuandong White, ... more

Allelic frequency; Genetic polymorphisms; Hemoglobin S; PCR-RFLP; Sickle cell disease; SNPs

Sickle cell anemia is an affection that causes chronic inflammation, with consequences for vaso-occlusion, oxidative stress and cytokine production. Genetic polymorphisms in markers involved in this process can modulate the inflammatory response, including polymorphisms -308G/A of TNFA (tumor necrosis factor alpha) and -509C/T of TGFB1 (transforming growth factor beta 1), reported to ... more
