    • Adrenalectomy regulates apoptotic-associated genes in rat hippocampus 
      Greiner Gebauer, Monika Marcela; Cárdenas Muñoz, Sergio Patricio; Parra, C.; Bravo, Jaime F.; Avalos, Ana María; Paredes Vargas, Alfonso; Lara Peñaloza, Hernán; Fiedler Temer, Jenny (HUMANA PRESS INC, 2001-08)
      Morphological studies of granular neurons of the hippocampus have shown that adrenalectomy (ADX) induces the cell death of granular neurons, an effect prevented by corticosterone replacement. We addressed the hypothesis ...
    • Chronic-intermittent cold stress in rats induces selective ovarian insulin resistance 
      Dorfman, Mauricio; Ramirez, Victor D.; Stener-Victorin, Elisabet; Lara Peñaloza, Hernán (2009)
      In rat ovary chronic cold stress increases sympathetic nerve activity, modifies follicular development, and initiates a polycystic condition. To see whether there is a relationship between the previously described changes ...
    • Cold stress induces metabolic activation of thyrotrophin-releasing hormone-synthesising neurones in the ... 
      Fiedler Temer, Jenny; Jara, P.; Luza, S.; Dorfman, M.; Grouselle, D.; Rage, F.; Lara Peñaloza, Hernán; Arancibia, S. (BLACKWELL PUBLISHING, 2006-05)
      Recent studies suggest thyrotrophin-releasing hormone (TRH) serves as a neurotransmitter and thereby provides a functional vegetative connection between the brain and the ovary. In the present study, magnocellular neurones ...
    • Corticosterone differentially regulates bax, bcl-2 and bcl-x mRNA levels in the rat hippocampus 
      Cárdenas Muñoz, Sergio Patricio; Parra, C.; Bravo, Jaime F.; Morales, P.; Lara Peñaloza, Hernán; Herrera-Marschitz Muller, Mario; Fiedler Temer, Jenny (ELSEVIER SCI IRELAND LTD, 2002-10-04)
      It has previously been shown that adrenalectomy (ADX) produces apoptosis in the granule cell of the dentate gyrus (DG), and that this effect is prevented by corticosterone replacement. Thus, we have investigated how this ...
    • Dopamine in human follicular fluid is associated with cellular uptake and metabolism-dependent generation ... 
      Saller, Sabine; Kunz, L.; Berg, D.; Berg, U.; Lara Peñaloza, Hernán; Urra, J.; Hecht, S.; Pavlik, R.; Thaler, C.J.; Mayerhofer, A. (Oxford University Press, 2014)
      studyquestion: Is the neurotransmitter dopamine (DA) in the human ovary involved in the generation of reactive oxygen species (ROS)? summary answer: Human ovarian follicular fluid contains DA, which causes the generation ...
    • Effects of long-term adrenalectomy on apoptosis and neuroprotection in the rat hippocampus 
      Andrés, Sergio; Cárdenas, Sergio; Lecocq Parra, Claudio; Bravo, Javier; Greiner, Monika; Rojas, Paulina; Morales, Paola; Lara Peñaloza, Hernán; Fiedler Temer, Jenny (2006)
      Reduction in corticosterone by acute adrenalectomy (5 d) promotes apoptosis in dentate gyrus (DG) granular neurons, an effect concomitant with variations in the expression of the Bcl-2 gene family implicated in apoptotic ...
    • Estrous cycle disruptor effect of an ethanolic extract from Buddleja globosa leaves and its main component ... 
      Parada, Mirtha; Valenzuela Barra, Gabriela; Delporte, Carla; Lara Peñaloza, Hernán (Universidad de Santiago de Chile, 2014)
      The estrous cycle disruptor effect of an ethanolic extract (EMATst) from Buddleja globosa leaves and standardized in its main component (verbascoside) was determined in rats after the subcutaneous administration of EMATst. ...
    • Readthrough acetylcholinesterase (AChE-R) and regulated necrosis: pharmacological targets for the regulation ... 
      Blohberger, J.; Kunz, L.; Einwang, D.; Berg, U.; Berg, D.; Ojeda, SR.; Dissen, GA.; Fröhlich, T.; Arnold, GJ.; Soreq, H.; Lara Peñaloza, Hernán; Mayerhofer, A. (Nature, 2015)
      Proliferation, differentiation and death of ovarian cells ensure orderly functioning of the female gonad during the reproductive phase, which ultimately ends with menopause in women. These processes are regulated by several ...
    • Role of RFRP-3 in the development of cold stress-induced polycystic ovary phenotype in rats 
      Squicciarini, V.; Riquelme, R.; Wilsterman, K.; Bentley, G. E.; Lara Peñaloza, Hernán (NLM (Medline), 2018)
      2018 Society for Endocrinology RFamide-related peptide (RFRP-3) is a regulator of GnRH secretion from the brain, but it can also act in human ovary to influence steroidogenesis. We aimed to study the putative local role ...
    • Testis of prepubertal rhesus monkeys receives a dual catecholaminergic input provided by the extrinsic ... 
      Mayerhofer, Artur; Danilchik, Michael; Pau, K. Y.Francis; Lara Peñaloza, Hernán; Russell, Lonnie D.; Ojeda, Sergio R. (Society for the Study of Reproduction, 1996)
      The mammalian testis is innervated by extrinsic catecholaminergic nerves and responds to catecholamines with steroid secretion. Although the primate testis has also been shown to be innervated, potential differences in the ...
