a b s t r a c tObjective: Adipocytokines have been reported to contribute to the pathogenesis of colorectal cancer (CRC). The aim of this matched case-control study was to explore circulating novel adipocytokines, such as serum visfatin, omentin-1 and vaspin levels in patients with CRC. Method: Serum visfatin, omentin-1, and vaspin levels were measured in 69 subjects (39 patients with colorectal cancer and 30 age-and sex-matched healthy controls) using enzyme-linked immunosorbent assay (ELISA) methods. Results: Compared with the controls, patients with CRC had significantly higher circulating omentin-1 (203.23 vs 9.12 ng/ml, p < 0.0001) visfatin (4.03 vs 2.01 ng/ml, p < 0.0001) and vaspin (0.54 vs 0.31 ng/ ml, p = 0.015) levels. After adjustment for covariates (age and body mass index), patients with CRC had significantly higher serum omentin-1 (p < 0.0001), visfatin (p < 0.0001), and vaspin (p = 0.040) levels than the control group. Furthermore, the results did not change when age and waist-to-hip ratio were considered as covariates in the general linear models. Conclusions: The observed higher levels of omentin-1, visfatin, and vaspin in patients with CRC, independent of measures of obesity, suggest that these adipocytokines may have a potential role in the development of CRC through mechanisms other than the indirect mechanisms that are active in the association between obesity and CRC.
IL-6 and TNF-alpha proinflammatory cytokine gene polymorphisms could change individual susceptibility to IBS and might have a role in pathophysiology of disease.
As the severity of nonalcoholic fatty infiltration increases, the incidence of abnormal hepatic vein waveforms increases and hepatic artery resistance index decreases.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
