Telomeres and Estrogens: The Unholy Nexus in Pathogenesis of Atherosclerosis.

Atherosclerosis (AS) is a complex inflammatory process and is categorized as a multifactorial disease involving the interplay of genetic and environmental factors. There are many factors which play role in predisposition and development of AS. In this review we have tried to address the basic pathophysiology of AS lesions and the role played by two important factors - telomeres and estrogens in the development of this disease.

RAD51 G135C gene polymorphism and risk of colorectal cancer in Kashmir.

RAD51 - a DNA double-strand breaks repair gene plays an important role in homologous recombination, a process frequently involved in cancer transformation. The aim of this study was to compare the distribution of the genotype of the RAD51 G135C polymorphism between colorectal cancer (CRC) patients and controls. We also tested the association between the G135C polymorphism of the RAD51 gene and the risk of CRC, and various clinicopathological parameters.

Mismatch repair pathway: molecules, functions, and role in colorectal carcinogenesis.

The microsatellite instability (MSI) pathway is one of the important mutational pathways that play a critical role in colorectal carcinogenesis. About 15% of colorectal cancers (CRCs) are characterized by MSI. MSI tumors usually arise because of a genetic defect in mismatch repair (MMR) genes, one of the main DNA-repairing systems.

Colorectal cancer: molecular mutations and polymorphisms.

Colorectal cancer (CRC) is one of the major causes of mortality and morbidity, and is the third most common cancer in men and the second most common cancer in women worldwide. The incidence of CRC shows considerable variation among racially or ethnically defined populations in multiracial/ethnic countries. The tumorigenesis of CRC is either because of the chromosomal instability (CIN) or microsatellite instability (MIN) or involving various proto-oncogenes, tumor-suppressor genes, and also epigenetic changes in the DNA.

Colorectal cancer: a researcher's perspective of the molecular angel's gone eccentric in the Vale of Kashmir.

Colorectal cancer (CRC), being the most common cancer, is the major cause of mortality and morbidity worldwide. In Kashmir, CRC has been found to be the third most common gastrointestinal cancer after esophageal and gastric. The etiology of CRC involves two pathways: chromosomal instability (CIN) and microsatellite instability.
