Abolition of the sex difference in Ngn3 by estradiol is depending on sex chromosome complement
Tomé, Karina; Cisternas, Carla Daniela; Scerbo Jaureguiberry, Maria Julia; Cambiasso, María Julia (Universidad Nacional de Córdoba, 2014)A growing body of evidences indicates that some sexually dimorphic traits cannot be solely explained as a result of gonadal steroid action during the critical period of brain masculinization (E18-PN10). Neurogenin 3 ... -
Activation of erk1/2 and axogenesis induced by estradiol depend on different calcium pools in male rat hypothalamic neurons in vitro
Cabrera Zapata, Lucas Ezequiel; Cambiasso, María Julia (2016)Estrogens generate a wide diversity of rapid “non-classical” effects which occur in a range from some seconds to few minutes (Arevalo et al., 2012), including the triggering of Ca2+ signals (Wong et al., 2012) and the ... -
Establecimiento de una técnica de cultivo de fibroblastps pulpares de rata
Soto, Sabrina Noelia; Cambiasso, María Julia (Sociedad Argentina de Investigación Odontológica, 2017)El objetivo de este trabajo fue desarrollar y poner a punto una técnica de cultivo celular que permita obtener un cultivo enriquecido en fibroblastos pulpares de rata con la finalidad de estudiar su respuesta frente a ... -
Histone deacetylase gene expression is regulated by sex chromosome complement in the amygdala of the developing mouse brain
Sosa, Camila; Cisternas, Carla Daniela; Conti, Romina Paula; Cambiasso, María Julia (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 ... -
Role of sex chromosome complement in the regulation of aromatase expression in developing mice brain
Cisternas, Carla Daniela; Arévalo, María Ángeles; Garcia-Segura, Luis Miguel; Cambiasso, María Julia (2016)During the critical period of sexual differentiation there are sex differences in brain aromatase expression that are time and regionally specific. Some of these sex differences cannot be explained by organizational — ... -
Role of X-linked genes on sex differences in neurogenin 3 expression in developing hypothalamic neurons
Cisternas, Carla Daniela; Arévalo, María Ángeles; Garcia-Segura, Luis Miguel; Cambiasso, María Julia (2016)Our previous findings indicate that sex chromosome complement regulates the generation of sex differences in mouse hypothalamic neuronal development. Higher expression of neurogenin 3 (Ngn3) in XX neurons mediates sex ... -
Sex differences in GABA-mediated calcium influx in hypothalamic neurons
Mir, Franco Rafael; Wilson, Carlos; Cambiasso, María Julia (2018)GABAA receptor (GABAAR) activation exerts trophic actions in immature neurons through depolarization of resting membrane potential gating the opening of voltage-dependent calcium channels. Previous results from our lab ... -
Sex differences in gene expression of X-linked histone demethylase Kdm6a in embryonic hypothalamic neurons
Cabrera Zapata, Lucas Ezequiel; Sosa, Camila; Cambiasso, María Julia (2018)Kdm6a and Kdm5c are histone demethylases that play an important role as epigenetic regulators of gene transcription by removing the di- and tri-methylation of Lys27 or Lys4 on histone H3 (H3K27me2/me3 - H3K4me2/me3). Both ... -
Sex differences in X-linked gene expression in embryonic hypothalamic neurons
Cabrera Zapata, Lucas Ezequiel; Cisternas, Carla Daniela; Cambiasso, María Julia (Sociedad Argentina de Investigación en Neurociencias, 2017)Although sex hormones are usually considered the main architects of sexual dimorphisms, recent studies have demonstrated that sex chromosomes can also induce sex differences in somatic gene expression in the absence of ... -
Sexual dimorphism in renal angiotensin receptors gene expression: sex chromosome complement involvement
Dadam, María Florencia; Cambiasso, María Julia; Porcari, Ciantia Yamilia; Godino, Andrea; Vivas, Laura Marta; Caeiro, Ximena Elizabeth (2016)The process of biological sex differentiation involves genetic and hormonal developmental steps. Clinical and basic findings indicate that the angiotensinergic system differentially regulates hydroelectrolyte and ...
