| Abstract | Background: The signalling pathway Fas and FasL system plays a fundamental role in the regulation of apoptotic cell death and any disturbance of this pathway has been shown to promote immune escapeand tumorigenesis. Many types of cancers show reduced expression of FAS and elevated FasL expression. The Fas21377G/A, and FasL2844T/C polymorphisms might be associated with increased risk of lung cancer.Objective: The interplay between genetic polymorphisms could participate in cancer development. This study aimed to examine the contribution of Fas21377AA and FasL2844CC genotypes to risk of developing lung cancer.Subjects and methods: A case-control study was conducted on 20 non small cell lung cancer (NSCLC) cases and 40 controls. Genotyping of Fas 21377AA and FasL 2844CC Single nucleotide polymorphisms (SNPs) by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) were done to all subjects.Results: The distribution of Fas and FasL genotypes showed a higher frequency of Fas AA genotype among patients compared to controls with an increased risk of lung cancer (OR 5.28; CI:1.35–20.65, P value .01). No statistically significant difference was found between patients and controls groups in respect to FasL genotypes. Gene to gene interaction between Fas and FasL genotypes showed significant differences between the patients and controls groups. As regards the combination between FasL TT+CT & Fas AA, FasL CC & Fas GG+GA and FasL CC & Fas AA genotypes where patients carrying FasL CC or Fas AA genotypes have increased risk to develop lung cancer, (OR 10.28, 95% CI; 1.68–62.74, P value .01), (OR 72, 95% CI; 5.55–132.99, P value .001) and (OR 9, 95% CI; 1.5–53.86, P value .01) respectively. The FasL-CC genotype showed 2.25 folds increased risk to develop lung cancer in non-smoker patients, P = .008. No correlation was found between the pathological types, the stage of lung cancer and the Fas and FasL genotypes.Conclusion: The interaction of the cell death pathwaygenes Fas and FasL polymorphisms could be associated with the risk of lung cancer, in the same respect Fas AA genotype could also potentiate this risk |

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.
