Effect of Inulin Intervention on Metabolic Control and Methylation of and Genes in Patients with Type 2 Diabetes Mellitus.

Background And Aims: Currently, treatments are being sought to improve the control of type II diabetes mellitus (T2DM), and inulin has been shown to be effective in reducing glucose levels and other metabolic control parameters. These effects on metabolic control may be associated with changes in the epigenetic modulation of genes of the insulin pathway. Therefore, our objective is to determine the effect of agave inulin in metabolic control parameters and in and genes' methylation in T2DM patients.

Use of Natural Products on the Control of and Production of Aflatoxins In Vitro and on Tomato Fruit.

affects fresh and dry fruit and vegetable products, and its toxic metabolites, namely aflatoxins, cause serious damage in humans. The objective of this research study was to evaluate the effect of commercial natural products as well as edible and nanostructured chitosan coatings on the development of and on the production of aflatoxins in vitro and in tomato. Treatments were as follows: chitosan 1%, chitosan coating, chitosan nanostructured coating, Citrocover 1% (citrus seed extract), Resinadher 0.

Association of the Promoter Methylation and the rs12917 Polymorphism of MGMT with Formation of DNA Bulky Adducts and the Risk of Lung Cancer in Mexican Mestizo Population.

O-Methylguanine-DNA methyltransferase (MGMT) is an enzyme that repairs the DNA damage caused by the tobacco habit, and low activity of this enzyme has been associated with a risk of lung cancer (LC). Our objective was to determine the association of the promoter methylation and the rs12917 polymorphism of MGMT with formation of DNA bulky adducts and the risk of LC in the Mexican Mestizo population. In this study are included 431 subjects.

CHRNA3 rs1051730 and CHRNA5 rs16969968 polymorphisms are associated with heavy smoking, lung cancer, and chronic obstructive pulmonary disease in a mexican population.

Background And Purpose: Smoking is a major public health problem worldwide. Polymorphisms in CHRNA3, CHRNA5, and CHRNB4 receptors play a critical role in nicotine dependence, lung cancer (LC) risk, and chronic obstructive pulmonary disease (COPD). This study characterized the CHRNA3 rs1051730 and CHRNA5 rs16969968 polymorphisms in a Mexican population and its association with nicotine dependence, LC, and COPD.

Polymorphisms associated with the risk of lung cancer in a healthy Mexican Mestizo population: Application of the additive model for cancer.

Lung cancer is the leading cause of cancer mortality in Mexico and worldwide. In the past decade, there has been an increase in the number of lung cancer cases in young people, which suggests an important role for genetic background in the etiology of this disease. In this study, we genetically characterized 16 polymorphisms in 12 low penetrance genes (AhR, CYP1A1, CYP2E1, EPHX1, GSTM1, GSTT1, GSTPI, XRCC1, ERCC2, MGMT, CCND1 and TP53) in 382 healthy Mexican Mestizos as the first step in elucidating the genetic structure of this population and identifying high risk individuals.
