Inner Mongolia; Metabolic lipid disorders; Polymorphism; PPARg2-Pro12Ala; Primary hypertension

In order to determine whether Pro12Ala polymorphism of the peroxisome proliferator-activated receptor γ2 (PPARγ2) gene contributes to susceptibility to primary hypertension and metabolic lipid disorders, 482 unrelated subjects from Inner Mongolia were studied, including 137 healthy normotensive (controls) and 345 hypertensive subjects. PCR-RFLP was used to determine the genotypes of ... more

Biomphalaria; Genetic variability; Polymorphism; RAPD-PCR; Schistosoma mansoni

Despite the implementation control programs, schistosomiasis continues to spread throughout the world. Among modern control strategies, vector control is currently being emphasized. Within this context, analysis of the genetic variability of intermediate host snails (Biomphalaria spp) is important because it allows identification of specific sequences of the genome of this ... more

Breast cancer; Drug therapy; Genetic; Glutathione transferase; Polymorphism

The glutathione S-transferase (GST) family consists of phase II detoxification enzymes that catalyze the conjugation of toxic substances, such as chemotherapeutic agents, to glutathione. We examined whether GSTT1/GSTT1“null”, GSTM1/GSTM1“null” and GSTP1Ile105Ile/GSTP1Ile105Val polymorphisms are associated with different response rates to neoadjuvant ... more

Beefmaster; Charolais; IGF1; Polymorphism; SNP IGF1/SnaBI

The IGF1 gene (insulin-like growth factor 1) is a candidate gene for marker-assisted selection strategies. A single nucleotide polymorphism in the promoter region (IGF1/SnaBI) has been reported to be associated with production traits in several cattle breeds. Here, we report its allelic frequencies in Charolais and Beefmaster breeds; we confirm its association with three growth ... more

ACE gene; Obstructive sleep apnea syndrome; Polymorphism

Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system, and there are reports in the literature describing its role in the development of cardiovascular system diseases, with I/D polymorphism of the ACE gene. We examined the relationship between a patient group with obstructive sleep apnea syndrome (OSAS) and a control group in terms of I/D ... more

Bladder cancer; CCR2-V64I; Chemokines; MCP-1 A-2518G; Polymorphism

Chemokines are potent proinflammatory cytokines that are implicated in numerous inflammatory diseases. Proinflammatory gene polymorphisms lead to variations in the production and concentration of inflammatory proteins. We investigated a possible association between polymorphisms in chemokine and chemokine receptor genes (MCP-1 A-2518G and CCR2-V64I) and bladder cancer risk. Genotypes were ... more

Abnormal Hb; Anemia; Hemoglobinopathies; Polymorphism; thalassemia

We looked for abnormal hemoglobins in blood samples sent for diagnosis of anemia. Identification of the hemoglobins was made using electrophoretic, chromatographic and molecular procedures. The 2020 blood samples were of patients from various regions of Brazil and from some other Latin American countries. Among the abnormal hemoglobins that we found, 3.5% are known to be rare, while 51% ... more

Colorectal cancer; Kashmir; Polymorphism; Restriction digestion; RFLP; TP53

Two TP53 gene polymorphisms at codon 47 (TP53 Pro47Ser) and at codon 72 (TP53 Arg72Pro) have been associated with susceptibility to various cancers. We carried out a case-control study and examined the genotype distribution of TP53 Pro47Ser and Arg72Pro single nucleotide polymorphisms (SNPs), using a PCR-RFLP approach, to determine if these two SNPs are ... more

Elderly; HDL cholesterol; Lipoprotein lipase; Polymorphism; Triglycerides

Lipoprotein lipase is essential for triglyceride hydrolysis. The polymorphisms S447X in exon 9 and HindIII in intron 8 have been associated with lower triglyceride levels and lower cardiovascular risk in adult men. We examined the association of these lipoprotein lipase polymorphisms with high-density lipoprotein (HDL) and triglyceride levels in elderly men. Blood samples were ... more

Cerebrovascular disease; Meta-analysis; Methylenetetrahydrofolate reductase; Polymorphism; Stroke

Several independent studies have reported the role of the methylenetetrahydrofolate reductase gene (MTHFR) A1298C polymorphism in strokes, but the results are inconclusive. To derive a more precise estimation of the relationship, a meta-analysis was performed in the present study. In this meta-analysis, a total of 13 studies, including 1974 cases and 2660 controls, were selected ... more
