Función y biogénesis mitocondrial. Diferencias entre géneros

Abstract

The main goal of this thesis has been focused on the study of gender differences in the mitochondrial morphology, function and biogenesis both in brown adipose tissue (BAT) and in liver, through the analysis of the several mitochondrial subpopulations isolated by means of the fractionation of the whole mitochondrial population. Results have reflected that the gender dimorphism stated in mitochondrial population both in BAT and in liver could be attributed to the existence to more highly differentiated mitochondria in female rats, which could be the result of a different mitochondrial biogenesis process between genders. Since the existence of a common factor which influences this process in both tissues could be hypothesized, sexual hormones could be one of the main factors responsible for the differences described in the present work
