Abstract 1349: NSAIDs: Multiple roles in multiple environments

Abstract

Abstract Non steroidal drugs are mainly known for their activities and use as anti-inflammatory, antipyretic compounds. But, in recent observations, they are exposed to use as an effective alternative compounds to prevent or stimulate different metabolic activities and help in preventing various neoplastic progression. They have specific role in controlling estrogen metabolism during breast cancer progression. Sometimes, they are used as an apoptotic induction in various cancers. Their role in hypoxia induced proliferation is also showing promising results. Different NSAIDs will help to induce the activities of various tumor suppressor genes. As chronic inflammation increases the risk for various cancers, therefore, it is important to eliminate inflammation through anti-Inflammatory compounds where NSAIDs are playing a vital role. Most of them are acting to prevent inflammation either via selective or non-selective COX based mechanism. The non-selective COX inhibitor sulindac and the COX-2 selective inhibitor etodolac etc. have been shown to prevent the formation and cause regression of adenomas in patients with familial polyposis. Unfortunately, COX-1 and/or COX-2 inhibition and depletion of physiologically important prostaglandins is associated with gastrointestinal, renal and cardiovascular toxicities that limit the use of NSAIDs and COX-2 inhibitors for cancer chemoprevention In this particular study, we are using various NSAIDs in a radiation-induced estogren treated breast cancer model to establish their role in differential expression of various cancer related genes selected from different cell cycle pathways microarray. Selection of biomarkers from these altered genes will help to develop a valid strategy for cancer prevention through precision based molecular targeted therapy.
