Abstract:
We studied plasma calcitonin gene-related peptide (CGRP) levels in obese women before (n = 24) and after (n = 13) weight loss, and in normal weight controls (n = 15). Furthermore, the influence of two isocaloric meals (high carbohydrate vs. high fat) on plasma CGRP concentrations was studied. The CGRP concentration in the obese group (32.26 +/- 2.01 pg/ml) was significantly (p less than 0.0001) higher than in the control group (21.64 +/- 0.15 pg/ml). After weight loss (14.3 +/- 0.72% of original weight) CGRP concentrations remained unchanged. Only the high-fat meal caused a significant (p less than 0.02) rise in CGRP levels. Our results indicate that elevated plasma CGRP levels may constitute a primary phenomenon in obese women, and that fat intake may be associated with increased CGRP secretion.

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
