Polymorphism of ACE gene as the genetic predisposition of coronary artery disease in Eastern India.

Aim: A case control study was designed to assess whether the prevalence of ACE gene polymorphism has any role in the development of CAD.

Methods: The study included unrelated 217 cases with CAD and 255 healthy controls. PCR was done using primers followed by agarose gel electrophoresis for study of different ACE gene polymorphisms.

Polymorphisms of CYP1A1, GSTM1 and GSTT1 Loci as the Genetic Predispositions of Oral Cancers and Other Oral Pathologies: Tobacco and Alcohol as Risk Modifiers.

Polycyclic aromatic hydrocarbons of tobacco require activation by phase I enzymes, such as cytochrome-P4501A1 (CYP1A1) to become an ultimate carcinogen, which are subjected to detoxification by phase II enzymes, especially glutathione S-transferases (GSTs). A study was designed to find whether genetic predisposition are risk modifiers of oral pathologies. The study included 102 cases with Oral Cancers (OCs), 68 cases with nonmalignant pathologies, 100 cases as control group.

Polymorphisms of methylenetetrahydrofolate reductase gene as the genetic predispositions of coronary artery diseases in eastern India.

Background: Gene-environment interaction is an important aspect in the development of coronary artery disease (CAD). The mutation (677C-T) of methylenetetrahydrofolate reductase (MTHFR) gene results in a decrease of the enzyme activity that leads to mild hyperhomocysteinemia. Elevated plasma level of homocysteine has been recognized as an independent risk factor for cardiovascular disease.

Cytogenetic monitoring in human oral cancers and other oral pathology: the micronucleus test in exfoliated buccal cells.

Oral cancer is a lifestyle-related cancer, with tobacco as a primary factor. Progression of oral cancer develops over several years from the stage of leukoplakia, erythroplakia, etc. A micronucleus test was applied to oral mucosal cells, considering them as the target site for carcinogens and cytogenetic damage.
