High MTHFR promoter methylation levels in men confer protection against ischemic stroke
2020-04-29
The MTHFR gene encodes methylenetetrahydrofolate reductase required for the metabolism of homocysteine (Hcy) – a previously reported independent risk factor for ischemic stroke (IS). In this study, we first aimed to clarify the association between DNA methylation leve
Oxygen-glucose deprivation and reoxygenation on human cerebral organoids alters expression related
2020-04-01
Ischemic stroke is one of the most common neurological disease. However, the impact of ischemic stroke on human cerebral tissue remains largely unknown; due to a lack of ischemic human brain samples. In this study, we used cerebral organoids derived from human induced pluripotent stem cells to eva
Genome-wide association study and fine mapping reveals candidate genes for birth weight
2020-03-27
Birth weight of pigs is an important economic factor in the livestock industry. The identification of the genes and variants that underlie birth weight is of great importance. In this study, we integrated two genotyping methods, single nucleotide polymorphism (SNP) chip analysis and restriction site associated DNA sequencing (RAD-seq) to genotype genome-wide SNPs. In total, 45,175 and 139,634 SNPs were detected with the SNP chip and RAD-seq, respectively. The genome-wide association study (GWAS) of the combined SNP panels identified two significant loci located at chr1: 97,745,041 and chr4: 112,031,589, that explained 6.36% and 4.25% of the phenotypic variance respect
