myostatin (mstn), also known as growth and differentiation factor-8 (gdf8), is a member of the transforming growth factor beta (tgf-?) superfamily that decreases growth in mammals. a single nucleotide polymorphism (snp) in the myostatin (gdf8) 3'utr of oar2 has been known as responsible for muscular hypertrophy in foreign breeds. in this study, in order to identify single nucleotide polymo...
background: hypospadias is one of the most common congenital abnormalities in the male which is characterized by altered development of urethra, foreskin and ventral surface of the penis. androgen receptor gene plays a critical role in the development of the male genital system by mediating the androgens effects. objective: in present study, we looked for new variations in androgen receptor pro...
BACKGROUND/AIMS We consider the situation that multiple genetic variants are underlying a heritable trait and assume that each contributes to the trait only to a small degree. The aim is to develop a statistical test for disease association of these multiple variants. METHODS We expect that p values resulting from a genome-wide case-control association analysis will fall into two classes: tho...
In 2013 Zhou et al. concluded that Salmonella enterica serovar Agona represents a genetically monomorphic lineage of recent ancestry, whose most recent common ancestor existed in 1932, or earlier. The Abstract stated 'Agona consists of three lineages with minimal mutational diversity: only 846 single nucleotide polymorphisms (SNPs) have accumulated in the non-repetitive, core genome since Agona...
Several studies have reported that the number of crossovers increases with maternal age in humans, but others have found the opposite. Resolving the true effect has implications for understanding the maternal age effect on aneuploidies. Here, we revisit this question in the largest sample to date using single nucleotide polymorphism (SNP)-chip data, comprising over 6,000 meioses from nine cohor...
Dark field imaging was employed to visualize and quantify complementary DNA-induced gold nanoparticle aggregation at the single-particle level, with a detection limit of 100 fM DNA, which allows the highly sensitive detection of single nucleotide polymorphisms (SNPs). Results suggested that the aggregation process is consistent with the cluster-cluster model.
OBJECTIVE To standardize the single nucleotide polymorphism array (SNPa) method in acute myeloid leukemia/myelodysplastic syndromes, and to identify the similarities and differences between the results of this method and karyotyping. METHODS Twenty-two patients diagnosed with acute myeloid leukemia and three with myelodysplastic syndromes were studied. The G-banding karyotyping and single nuc...
