Sex-specific genetic effects influence variation in body composition

Genetic basis of sex - specific color pattern variation in Drosophila

Cold acclimation in Peromyscus: individual variation and sex effects in maximum and daily metabolism, organ mass and body composition.

We studied metabolic and organ mass responses to thermal acclimation (7 weeks at 5 degrees C or 23 degrees C) in deer mice, Peromyscus maniculatus. Cold acclimation resulted in significantly higher maximal oxygen consumption in thermogenesis (V(O(2)max)) and daily mean oxygen consumption (V(O(2)mean)), an increase in the mass of most visceral organs, a lower absolute body fat and a marginally s...

Conservation of Regional Variation in Sex-Specific Sex Chromosome Regulation.

Regional variation in sex-specific gene regulation has been observed across sex chromosomes in a range of animals and is often a function of sex chromosome age. The avian Z chromosome exhibits substantial regional variation in sex-specific regulation, where older regions show elevated levels of male-biased expression. Distinct sex-specific regulation also has been observed across the male hyper...

Sex Steroid Metabolism and Body Composition

Background: The bioactive androgens testosterone (T) and dihydrotestosterone (DHT) regulate bone and fat mass in men. The effects of androgens are largely determined by the rate of their synthesis and inactivation. Irreversible conjugation of androgens or androgen metabolites by UDP glucuronosyltransferases (UGTs) into water-soluble glucuronidated androgen metabolites plays an important role in...

Sex-specific association of anthropometric measures of body composition with arterial stiffness in a healthy population

BACKGROUND Anthropometric measures of body composition and arterial stiffness are commonly used as indicators of cardiovascular risk. Little is known, however, about the association of the anthropometric measures with arterial stiffness, especially in a healthy, generally non-obese population. MATERIAL/METHODS In a sample of 352 healthy subjects (200 premenopausal women), 3 arterial stiffness...
