Sex-specific adaptive homeostasis in D. melanogaster depends on increased proteolysis by the 20S Proteasome: Data-in-Brief
Adaptive homeostasis enables rapid cellular signaling, leading to transcriptional and translational modifications (Davies, 2016) [1]. The Proteasome is one of the main cellular proteolytic enzymes that plays an essential role in the rapid clearance of oxidatively damaged cellular proteins, and is highly responsive to oxidative stress. Upon exposure to even very low, signaling levels of oxidants...
متن کاملSexual dimorphism in oxidant status in spontaneously hypertensive rats.
Male spontaneously hypertensive rats (SHR) have a blunted pressure-natriuresis relationship and enhanced oxidative stress compared with female SHR. Furthermore, oxidative stress contributes to abnormal renal Na+ handling and renal damage in hypertension. The aim of this study was to determine whether a sex difference exists in renal inner medullary hydrogen peroxide (H2O2) levels and/or antioxi...
متن کاملIntersex Modifying Genes in Wild Strains of Drosophila Melanogaster.
HE sex determining mechanism in diploid Drosophila melanogaster is T completely stable. No intersexual individuals are produced from hybridizing strains of D. melanogaster collected from widely separated geographical localities. In Lymantria, on the contrary, GOLDSCHMIDT (1934) has shown that the potencies of the X chromosome sex gene differs in races from Europe and Japan. The degree of sexual...
متن کاملManipulation of feeding regime alters sexual dimorphism for lifespan and reduces sexual conflict in Drosophila melanogaster
Sexual dimorphism for lifespan (SDL) is widespread, but poorly understood. A leading hypothesis, which we test here, is that strong SDL can reduce sexual conflict by allowing each sex to maximize its sex-specific fitness. We used replicated experimental evolution lines of the fruit fly, Drosophila melanogaster, which had been maintained for over 360 generations on either unpredictable 'Random' ...
متن کاملLongevity in Some Wild Type and Hybrid Strains of Drosophila melanogaster
It is known that aging is a multifactorial mechanism composed of both genetic and environmental components. The main evolutionary theories of aging are antagonistic pleiotropy and mutation accumulation, neither of which has substantial experimental support yet. In this study, the longevities of three wild type strains of Drosophila melanogaster and F1 hybrids derived from them were determined. ...
