Sex differences in body fluid homeostasis: Sex chromosome complement influences on bradycardic baroreflex response and sodium depletion induced neural activity
(Pergamon-Elsevier Science Ltd, 2015-12)
Clinical and basic findings indicate that angiotensin II (ANG II) differentially modulates hydroelectrolyte and cardiovascular responses in male and female. But are only the activational and organizational hormonal effects ...
Study of chromosomal and nucleolar aspects in testes of Nysius californicus (Heteroptera: Lygaeidae)
(2007-05-18)
In Nysius californicus (family Lygaeidae, subfamily Orsillinae), a pest commonly known as the seed bug, the chromosome complement is 2n = 16 (12A + 2m + XY), testes are formed by seven seminiferous tubules covered by an ...

Sex chromosome complement contributes to sex differences in bradycardic baroreflex response
(Hypertension, 2011)
To investigate whether sex chromosome complement modulates bradycardic baroreflex response and contributes to the angiotensin II– bradycardic baroreflex sex differences, we used the four core genotype mouse model in which ...
Estradiol-dependent axogenesis and Ngn3 expression are determined by XY sex chromosome complement in hypothalamic neurons
(Nature Research, 2020-12)
Hypothalamic neurons show sex differences in neuritogenesis, female neurons have longer axons and higher levels of the neuritogenic factor neurogenin 3 (Ngn3) than male neurons in vitro. Moreover, the effect of 17-β-estradiol ...
Histone deacetylase gene expression is regulated by sex chromosome complement in the amygdala of the developing mouse brain
(2020)
Sexual differentiation of the rodent brain depends mainly on the action of androgens secreted by the fetal testis during the perinatal critical period (E17-P10). Recently, the role of genetic factors derived from sex ...
Chromosome complement and meiosis in three species of the Neotropical bug genus Antiteuchus (Heteroptera, Pentatomidae, Discocephalinae)
(Sociedade Brasileira de Genética, 2006-12)
Orcein staining of spermatocytes was used to study the meiotic behavior of holocentric chromosomes in three member of the genus Antiteuchus (commonly known as stink bugs). We describe and illustrate the karyotype of ...
Regulation of aromatase expression in the anterior amygdala of the developing mouse brain depends on ERβ and sex chromosome complement
(Nature Publishing Group, 2017-12-13)
During development sex differences in aromatase expression in limbic regions of mouse brain depend on sex chromosome factors. Genes on the sex chromosomes may affect the hormonal regulation of aromatase expression and this ...
Chromosome evolution in the erythrinid fish, Erythrinus erythrinus (Teleostei : Characiformes)
(Nature Publishing Group, 2004-08-01)
The genus Erythrinus belongs to the family Erythrinidae, a neotropical fish group. This genus contains only two described species, Erythrinus erythrinus being the most widely distributed in South America. Six samples of ...
Single Origin of Sex Chromosomes and Multiple Origins of B Chromosomes in Fish Genus Characidium
(Public Library Science, 2014-09-16)
Chromosome painting with DNA probes obtained from supernumerary (B) and sex chromosomes in three species of fish genus Characidium (C. gomesi, C. pterostictum and C. oiticicai) showed a close resemblance in repetitive DNA ...
