Stearoyl-coenzyme A desaturase 1 (SCD1) is the key limiting enzyme in the synthesis of monounsaturated fatty acids, and plays a crucial role in the regulation of oleic acid. In this study, 165 ten-week-old Cherry Valley ducks were used to investigate single nucleotide polymorphisms (SNPs) in the 5' regulatory region of the SCD1 gene, and their associations with duck serum biochemical levels and fatty acid composition.
This study investigated the haplo-block structure, haplotype sharing, and diversity in extensively raised chicken populations of Southern Africa. Two hundred ninety village chickens from Malawi (N = 30), South Africa (N = 132), and Zimbabwe (N = 128) were included in the study, from which 649, 2104, and 2442 haplo-blocks were observed, respectively. The majority of haplo-blocks were smaller than 25 kb in size and only five blocks were more than 2000 kb in size.
The aim of this study was to determine whether single nucleotide polymorphisms (SNPs) in APM1 contribute to disorders of lipid metabolism in hypertensive disorder complicating pregnancy (HDCP). The study included 178 pregnant women with HDCP and 243 healthy pregnant controls. Using PCR-restriction fragment length polymorphism, we detected the frequencies of genotypes, alleles, and haplotypes of two SNPs, +45T>G (rs2241766) and +276G>T (rs1501299), in APM1.
