| Abstract | Genetic polymorphisms are defined as changes within the DNA sequences of genes that have frequencies in the population higher than 1%. The glutathione S-transferases play an important role in the cellular detoxification systems involved in oxidative stress that can lead to accumulation of reactive oxygen species. Epidemiological studies have suggested that individuals with homozygous deletion of glutathione S-transferase mu 1 (GSTM1) and glutathione S-transferase theta 1 (GSTT1) are at higher risk of developing several types of neoplasias. The p53 protein is highly expressed in tumors and transformed cells, and the p53 is a classical tumor suppressor gene involved in regulating cell growth and development. In this study, we investigated the prevalence of polymorphisms in the p53, GSTM1, and GSTT1 genes in a population from Goiânia. We evaluated the polymorphisms of these genes in peripheral blood samples. The null or present polymorphism of GSTM1 and GSTT1 genes and Arg/Pro of the p53 gene were analyzed. Our results revealed a higher frequency of the GSTM1-null polymorphism (72.4%) than the GSTM1-present genotype (27.6%). For GSTT1, we observed higher frequency for the null genotype (65.5%) compared to the present genotype (34.5%). Analysis of p53 gene polymorphisms showed a higher frequency for the genotype Arg/Pro (66%) and a lower frequency for the Arg/Arg (23%) and Pro/Pro (11%) genotypes. It is essential to understand polymorphism frequencies in different populations and to evaluate the role of genetic polymorphisms and their effects on health. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
