OBJECTIVE Recent studies suggest an involvement of the obese (OB) gene and its product leptin in the regulation of body fat. Since adults with growth hormone deficiency (GHD) have a high body fat mass which can be normalized with recombinant human (rh) GH therapy, we investigated whether GH influences serum leptin directly or indirectly via its lipolytic effect. DESIGN Fourteen adults with GH...

Data from 3,593 beef heifers and 4,079 of their steer paternal half-sibs were used to estimate genetic parameters of and among female growth and reproductive traits and male carcass traits. Estimates of heritability for adjusted 205-d weight, adjusted 365-d weight, age at puberty, calving rate, and calving difficulty measured on females were .16, .38, .47, .19, and .18, respectively; estimates ...

Previous studies have demonstrated positive-inotropic effects of calcitonin gene-related peptide (CGRP), but the mechanisms remain unclear. Therefore, two experiments were performed to determine the physiological correlates of the positive-inotropic effects of CGRP. Treatments designed to antagonize the effects of physiologically active CGRP₁₋₃₇ included posttreatment with CGRP₈₋₃₇ and pretreat...

STATs are a family of latent transcription factors that reside in the cytoplasm of resting cells. The STAT1 transcription factor gene located on the chromosome 2 at interval 60 to 63 cM. This factor upon stimulation with INF gamma, dimerizes and translocate to the nucleus where mediates transcriptional regulation. In this study, we estimated the allele and genotype frequencies of STAT1/Pag<...

to test the effect of culling herd life from the breeding goal function, 4 different selection indices were established as: index 1: using milk production (milk), fat percentage of milk (fat%) and rear udder height (ruh); index 2: using milk , fat% and fore teat placement (ftp), index 3: using milk, fat% and fore udder attachment (fua); and index 4: using milk, fat%, ruh, ftp and fua) under two...

Calcitonin gene-related peptide (CGRP; official name CALCA) has a variety of functions and exhibits both angiogenic and anti-inflammatory properties. We previously reported the angiogenic effects of the CGRP family peptide adrenomedullin in oxygen-induced retinopathy; however, the effects of CGRP on ocular angiogenesis remain unknown. Herein, we used CGRP knockout (CGRP(-/-)) mice to investigat...

UNLABELLED BACKGROUND Aerobic capacity (VO2max) is highly dependent upon body composition of an individual and body composition varies with ethnicity. The purpose of this study was to check the concurrent validity of the non-exercise prediction equation developed by Jackson and colleagues (1990) using percentage body fat as a variable in Asian Indian adults. METHODS One hundred twenty coll...

OBJECTIVE Receptor activity-modifying proteins (RAMPs) 1, 2, and 3 are unusual accessory proteins that dictate the binding specificity of two G protein-coupled receptors involved in energy homeostasis: calcitonin gene-related peptide (CGRP) and amylin receptors. These proteins are expressed throughout the central nervous system (CNS), including in the brain regions involved in the regulation of...
