A quantitative trait locus for oleic fatty acid content on Sus scrofa chromosome 7.

A partial genome scan using microsatellite markers was conducted to detect quantitative trait loci (QTLs) for 10 fatty acid contents of backfat on 15 chromosomes in a porcine resource population. Two QTLs were discovered on Sus scrofa chromosome 4 (SSC4) and SSC7. The QTL on SSC4 was located between marker loci sw1336 and sw512, and this QTL was detected (P < 0.

Klotho is a genetic risk factor for ischemic stroke caused by cardioembolism in Korean females.

An aging-suppressor gene, klotho, is a candidate factor for vascular disease because its deficiency leads to impaired endothelium-dependent vasodilation and impaired angiogenesis. We investigated the association of polymorphisms in klotho with ischemic stroke. We searched for sequence variants in promoter and exons of klotho gene.

Sequence variants of ACE, AGT, AT1R, and PAI-1 as genetic risk factors for vascular dementia.

Sequence variants of angiotensin converting enzyme (ACE) insertion/deletion (I/D), angiotensinogen (AGT) T235M, angiotensin II type 1 receptor (AT1R) A1166C, and plasminogen activator inhibitor-1 (PAI-1) 4G/5G were analyzed to see their genetic associations with vascular dementia as its candidate genetic risk factors involving renin-angiotensin and fibrin systems. While the ACE I/D, AT1R A1166C, and PAI-1 4G/5G did not contribute to the genetic susceptibility to vascular dementia (P>0.05), a significant association with vascular dementia was shown in the T235M polymorphism of AGT.

Haplotype analysis of single nucleotide polymorphisms in VEGF gene for vascular dementia.

A case-control study was performed to identify single nucleotide variants of vascular endothelial growth factor (VEGF) gene associated with vascular dementia. Seven SNPs in promoter, 5'-UTR, 3'-UTR, and introns of VEGF gene were identified in 24 Koreans. Three of them, -1154G/A, -7C/T, and 13553C/T, were selected based on allele frequency and linkage disequilibrium (LD), and genotyped in 207 vascular dementia patients and 207 control subjects.

Analysis of the SREBF2 gene as a genetic risk factor for vascular dementia.

A case-control study was performed to examine the association between vascular dementia and the polymorphisms of the human gene encoding sterol regulatory element binding protein-2 (SREBF2) that regulates cholesterol metabolism. The 16 genetic variants of SREBF2 were identified in 24 Koreans, and 5 out of 16 variants were genotyped in 207 vascular dementia patients and 207 control subjects. Significant association with vascular dementia was shown in 34995G/T with the GT genotype (odds ratio [OR] = 1.
