Sex Chromosome Turnover in Moths of the Diverse Superfamily Gelechioidea
(Oxford University Press, 2019-04-08)
Sex chromosomes play a central role in genetics of speciation and their turnover was suggested to promote divergence. Invertebrates, sex chromosome–autosome fusions resulting in neo-sex chromosomes occur frequently in male ...
Sex-steroid rapid action and its role in invasiveness and metastasis of breast cancer
(Springer, 2012)
Sex steroids, particularly estrogen and progesterone, promote normal breast tissue growth and differentiation. Prolonged exposure of estrogen and/or progesterone is well-documented to be the risk factor for breast cancer ...
Tracking the evolution of sex chromosome systems in Melanoplinae grasshoppers through chromosomal mapping of repetitive DNA sequences
(BioMed Central, 2013-08)
Background: The accumulation of repetitive DNA during sex chromosome differentiation is a common feature of many eukaryotes and becomes more evident after recombination has been restricted or abolished. The accumulated ...
Switching attraction to inhibition: Mating-induced reversed role of sex pheromone in an insect
(Company of Biologists, 2010-09)
In the moth, Agrotis ipsilon, newly mated males cease to be attracted to the female-produced sex pheromone, preventing them from re-mating until the next night, by which time they would have refilled their reproductive ...
Role of Sex Hormones in Cytoskeletal Structure: Implications in Cellular Lifespan
(Bentham Science Publishers, 2019)
The cytoskeleton is composed of intracellular structures that maintain cellshape, interconnect organelles to each other, often attached to the cell membrane and isinvolved in signaling pathways. Sex steroids are effective ...
Physiopathology of diabetes: role of endocrine glands in experimental diabetes
(Consejo Nacional de Investigaciones Científicas y Técnicas, 1961)
In the normal or diabetic condition the liver plays a fundamental homeostatic role, since it is the organ that produces glucose and thus governs the blood sugar level (28). The glucose output from the liver is increased ...
Spatial sex segregation in the dioecious grass Poa ligularis in northern Patagonia: The role of environmental patchiness
(Springer, 2002-01)
We examined the effect of environmental patchiness on the spatial segregation of the sexes in the dioecious anemophilus grass Poa ligularis. Because the species is sensitive to grazing, a better understanding of environmental ...
Sex hormone binding globulin during an annual reproductive cycle in the hepatopancreas and ovary of pejerrey (Odontesthes bonariensis)
(Academic Press Inc Elsevier Science, 2019-02)
In the present study, we determined the hepatopancratic shbg transcript abundance and ovarian immunoreactive Shbg (ir-Shbg) localization in pejerrey females at different gonadal stages during an annual ovarian cycle. In ...
The role of sex steroids on cellular events involved in vascular disease
(Pergamon-Elsevier Science Ltd, 2012-11)
In this work we checked the hypothesis whether estrone, progesterone, and testosterone are able to modulate the interactions between platelets, monocytes, and endothelial cells either under basal or inflammatory conditions. ...
