RESUMO
INTRODUCTION: Genetic variations in the calpain 10 gene (CALPIN-10), single nucleotide polymorphisms-43 (SNP-43), have increased the risk of type 2 diabete mellitus (T2DM) and coronary artery disease (CAD). METHODS: We studied the control and CAD groups for association of association of SNP-43 in the CALPIN-10 gene with T2DM and other risk factors of its complications. Overall, we examined 452 individuals, 224 patients with CAD and 228 healthy subjects for CAD in Iranian population. All the subjects were genotyped for the CALPIN-10, SNP-43 by polymorphism chain reaction (PCR) and restriction fragment length polymorphism (RFLP) methods, using biochemical methods to detect fasting glucose and other biochemical factors in the blood sample. We assessed frequencies of SNP-43 alleles between CAD and normal population groups. RESULTS: In CAD patients, the GG allele was significantly associated with T2DM and GG allele was causing high level of glucose. But in control group, there was no relationship between them. Between clinical and biochemical risk factors with different genotypes there was no significant difference in the compared group. CONCLUSION: The results of our study suggest no significant association between SNP-43 and the risk of T2DM. In other words, CALPIN-10 did not show a major diabetes gene pool capacity in normal southern Iranian population.
RESUMO
INTRODUCTION: Endothelial lipase (EL) is a protein from the triglyceride lipase family which plays an important role in high-density lipoprotein (HDL) metabolism. One of the most frequently studied variants is 584C/T which causes the amino acid threonine at codon 111 to convert to isoleucine. Many studies have shown the association of this variant with HDL-C level and CAD disease. METHODS: The population of this study consists of 140 patients (all males) with angiographically confirmed coronary artery disease (CAD) and 80 controls. Polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) was carried out for genotyping of LIPG 584C/T. Data were analyzed using SPSS. RESULTS: The results of the study indicated that the frequency of T allele was significantly lower among CAD patients than among controls (0.27 vs 0.36, P = .004). However, no significant correlation was found between the 584C/T variant and serum HDL-C level. Multivariate regression analysis confirmed that the T allele is significantly associated with CAD disregarding the age, hypertension, hypercholesterolemia, diabetes and HDL-C (OR = 0.494, 95% CI = 0.253- 0.968, P =.040). CONCLUSION: It was concluded that the T allele was associated with protection from CAD in Fars province independent of HDL-C level.
RESUMO
Crude extracts or phytochemicals obtained from some plants have potential anti-cancer properties. Teucrium persicum is an Iranian endemic plant belonging to the Lamiaceae family which has traditionally been used to relieve abdominal pains. However, the anti-cancer properties of this species of the Teucrium genus have not been investigated previously. In this study, we have used a highly invasive prostate cancer cell line, PC-3, which is an appropriate cell system to study anti-tumor properties of plants. A methanolic extract obtained from T persicum potently inhibited viability of PC-3 cells. The viability of SW480 colon and T47D breast cancer cells was also significantly decreased in the presence of the T persicum extract. Flow cytometry suggested that the reduction of cell viability was due to induction of apoptosis. In addition, the results of wound healing and gelatin zymography experiments supported anti-cell invasion activity of T persicum. Interestingly, sublethal concentrations of T persicum extract induced an epithelial-like morphology in a subpopulation of cells with an increase in E-Cadherin and ß-Catenin protein levels at the cell membrane. These results strongly suggest that T persicum is a plant with very potent anti-tumor activity.
