Down regulation of tumour biomarkers in colon cancer cells with IRNA PFK-1 plus metformin.

Purpose: Metformin has been widely used for the treatment of Type 2 Diabetes Mellitus (T2DM), hyperglycemia and polycystic ovarian syndrome. Recent studies have suggested the potential of this substance as a cancer chemopreventive agent. We evaluated the antitumoral effect of iRNA-PFK-1 and the combined therapy iRNA-PFK-1 + metformin in RKO p53-positive cells.

The 482Ser of PPARGC1A and 12Pro of PPARG2 Alleles Are Associated with Reduction of Metabolic Risk Factors Even Obesity in a Mexican-Mestizo Population.

The aim of this study was to investigate the relationship between functional polymorphisms Gly482Ser in PPARGC1A and Pro12Ala in PPARG2 with the presence of obesity and metabolic risk factors. We included 375 individuals characterized as Mexican-Mestizos and classified by the body mass index (BMI). Body dimensions and distribution of body fat were measured.
