Background: Chemerin, encoded by the retinoic acid receptor responder 2 (RARRES2) gene is an adipocytesecreted protein with autocrine/paracrine functions in adipose tissue, metabolism and inflammation with a recently described function in vascular tone regulation, liver, steatosis, etc. This molecule is believed to represent a critical endocrine signal linking obesity to diabetes. There are no data available regarding evolution of RARRES2 in non-human primates and great apes. Expression profile and orthology in RARRES2 genes are unknown aspects in the biology of this multigene family in primates. Thus; we attempt to describe expression profile and phylogenetic relationship as complementary knowledge in the function of this gene in primates. To do that, we performed A RT-PCR from different tissues obtained during necropsies. Also we tested the hypotheses of positive evolution, purifying selection, and neutrality. And finally a phylogenetic analysis was made between primates RARRES2 protein. Results: RARRES2 transcripts were present in liver, lung, adipose tissue, ovary, pancreas, heart, hypothalamus and pituitary tissues. Expression in kidney and leukocytes were not detectable in either species. It was determined that the studied genes are orthologous. Conclusions: RARRES2 evolution fits the hypothesis of purifying selection. Expression profiles of the RARRES2 gene are similar in baboons and chimpanzees and are also phylogenetically related. © 2015 González-Alvarez et al.

Objective: To determine the prevalence of the metabolic syndrome (SM) and its components in teenagers from the metropolitan area of Monterrey Nuevo Leon, Mexico (AMM). Method: A transversal research involving 254 teenage students from 10 to 19 years old. To research investigated their personal characteristics, anthropometrics measures, glucose, triglycerides and cholesterol HDL. The SM definition was adapted from the one suggested by the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATPIII). Results: The SM prevalence was 9.4 % (IC95%: 5.8 to 13.0), there was not a difference between the sexes. The prevalence among each SM component was: 24.4% for high triglycerides, 20.1% for abdominal obesity, 19.0% for cholesterol of lipoproteins of a high density (HDL-c) low, 11.4 % for high glucose and for high blood pressure (9.1% diastolic and 5.9% systolic). The prevalent SM phenotypes were corporal mass (IMC) (OR = 4.93, IC95%: 2.26, 10.73) and the IMC interaction of the teenager with a family history of obesity (OR = 1.37, IC95%: 1.0, 1.87). It was observed that those with a family history of diabetes type 2 only experienced a marginal effect. Conclusion: The SM prevalence in teenagers from AMM is high it was an alarming situation if it continues into adulthood. The existence of obesity in relatives of the first and second grade, altogether with teenager IMC are important prediction factors of SM. © 2010 Instituto Nacional de Cardiología Ignacio Chávez.
