Abstract

Accumulating evidence indicates that activation of the peroxisome proliferator-activated receptor-gamma (PPAR-gamma) dampens the inflammation cascade and inhibits tumor growth of the lung, suggesting that it has tumor suppressor functions. We performed a case-control study of 500 incident lung cancer cases and 517 age- and sex frequency-matched cancer-free controls in a Chinese population to investigate the role of 11 selected single nucleotide polymorphisms (SNPs) of PPAR-gamma in the etiology of lung cancer. We found that decreased lung cancer risk was statistically significantly associated with seven SNPs (P = 0.0004 for rs13073869 and 0.0130 for rs1899951 in a dominant model; P = 0.0310 for rs4135247 in a log-additive model; and P = 0.0468 for rs2972162, 0.0175 for rs709151, 0.0172 for rs11715541 and 0.0386 for rs1175543 in an overdominant model). Consistent with these results of single-locus analysis, both the haplotype and the diplotype analyses revealed a protective effect of the haplotype 'AGA' and 'AAA' of rs13073869, rs1899951 and rs4135247. Furthermore, we observed a statistically significant interaction between the rs1899951 and cigarette smoking. Our results indicate that PPAR-gamma polymorphisms and their interact...Continue Reading

Aneurysm

Aneurysms are outward distensions or bulges that occurs in a weakened wall of blood vessels. Discover the latest research on aneurysms here.

Aortic Aneurysm

An aortic aneurysm is the weakening and bulging of the blood vessel wall in the aorta. This causes dilatation of the aorta, which is usually asymptomatic but carries the risk of rupture and hemorrhage. Find the latest research on aortic aneurysms here.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
