Magic™ Anti-RBP4 monoclonal antibody, clone C693N

Aim: Adipokines are associated with several oxidative stress-related diseases and pathologic conditions. We aimed to assess the association between antioxidants and adipokines in obese adults. Methods and Materials: In this cross-sectional study, a total of 160 obese women were included. Body composition and anthropometric characteristics were measured. Dietary intakes were assessed by 3-day, 24-h dietary recall. Blood samples were obtained following an overnight fasting. Serum concentrations of adipokines including progranulin, retinol binding protein 4 (RBP4) and Angiopoietin-related growth factor 6 (ANGPTL6) was measured using an enzyme-linked immunosorbent assay. ANCOVA and the linear regression model analysis was performed to assess the relationship between Progranulin, RBP4, AnGPTL6, and antioxidants. Results: Mean age of included women was 39.31 +/- 12.10. Mean and standard deviation for BMI was 35.05 +/- 4.26 in this obese population. There was a positive significant association between ANGPTL6 and vitamin D intake (p < 0.001). Also, there was a marginal association between RBP4 and vitamin A (p = 0.063) intake, but after adjustment age, and fat mass, we found a significant association (p = 0.008). However, the associations between dietary antioxidants, progranulin, and ANGPTL6 were not statistically significant. Conclusions: ANGPTL6 and RBP4 levels directly associated with dietary vitamins D and A intake, respectively. But, according to the results, the association between ANGPTL6 and vitamin D was bidirectional. The suggested associations probably can be useful in the development of interventional studies for management of chronic diseases. (c) 2019 Diabetes India. Published by Elsevier Ltd.

BackgroundObesity is closely associated with colorectal cancer (CRC), but the underlying mechanism is unclear. We thus evaluated the expression of the adipokine gene family in CRC tissues and its clinicopathological implications. MethodsCorrelations between the mRNA expression levels of the adipokine gene family (ADIPOQ, ADIPOR1/2, LEP, LEPR, RETN, RETNLB, RBP4, SFRP5, NAMPT, and SPP1) in CRC tissue and clinicopathologic factors were analyzed using data from The Cancer Genome Atlas database. ResultsTissue samples from 369 patients were analyzed, and 82 deaths occurred during follow-up (median, 670 days). Overall, mortality was associated with positive venous invasion, higher TNM stage, and increased ADIPOR1 (adiponectin receptor 1 gene) and SPP1 (secreted phosphoprotein gene 1) mRNA expression. Higher ADIPOR1 (odds ratio [OR]: 3.29, 95% confidence interval [CI]: 1.33-8.13) and SPP1 (OR: 2.31, 95%CI: 1.49-3.59) levels were independently associated with increased mortality. A Kaplan-Meier survival analysis showed shorter overall survival times in patients with higher ADIPOR1 (P=0.006) and SPP1 (P<0.001) expression. ConclusionsUpregulation of ADIPOR1 and SPP1, among the adipokine gene family, in cancer tissue is associated with poor survival in CRC, suggesting a potential mechanism linking obesity and CRC. ADIPOR1 and SPP1 expression could become useful prognostic indicators after further validation.
