Abstract
INTRODUCTION Given the suggested metabolic regulatory effects of stress-responsive genes and based on the impacts of early-life stress on HPA axis development, this study aimed to characterize the maternal separation (MS) impact on the communication between glucose metabolism and HPA axis dysregulations under chronic social defeat stress (CSDS). METHODS During the first 2 weeks of life, male Wistar rats were either exposed to MS or left undisturbed with their mothers (Std). Starting on postnatal day 50, the animals of each group were either left undisturbed in the standard group housing (Con) or underwent CSDS for 3 weeks. There were four groups (n = 10/group): Std-Con, MS-Con, Std-CSDS, and MS-CSDS. RESULTS Early and/or adult life adversity reduced β-cell number, muscular FK506-binding protein 51 (FKBP51) content, and BMI in adulthood. The reduction of β-cell number and BMI in the MS-CSDS rats were more profound than MS-Con group. CSDS either alone or in combination with MS reduced locomotor activity and increased and decreased corticotropin-releasing factor type 1 receptor (CRFR1) content, respectively, in hypothalamus and pancreas. Although, under CSDS, MS intensified HPA axis overactivity and reduced isolated islets' insulin secretion, it could promote resilience to depression symptoms. No differences were observed in hypothalamic Fkbp5 gene DNA methylation and glucose tolerance among groups. CONCLUSION MS exacerbated HPA axis overactivity and the endocrine pancreas dysfunctions under CSDS. The intensified corticosterone secretion and the diminished content of pancreatic CRFR1 protein could be involved in the reduced β-cell number and islets' insulin secretion under CSDS. The decreased muscular FKBP51 content might be a homeostatic response to slow down insulin resistance development under chronic stress.

AN ACAD BRAS CIENC 2022; 94:e20210673.

Abstract
Chronic alcohol consumption affects various neurotransmitters, especially those implicated in the transitioning to alcohol use disorders (particularly dopaminergic and CRFergic systems). Few studies have investigated moderate alcohol consumption and its harmful consequences. The objective of this work was to analyze behavioral and neurochemical (dopaminergic and CRFergic systems) alterations during chronic moderate alcohol consumption. Twelve male Wistar rats were submitted to an intermittent alcohol ingestion protocol (alcohol group) for four weeks. The control group consisted of six rats. Open Field and Elevated Plus Maze tests were used for analysis of motor and anxiety-like behaviors. Immunohistochemistry analysis was performed in dopaminergic and CRFergic systems. Animals exposed to alcohol consumed moderate doses, chronic and intermittently. Behavioral tests detected fewer fecal boli in the alcohol exposed group, and immunohistochemical analysis indicated fewer dopamine-immunoreactive cells in the ventral tegmental area, and more CRF-immunoreactive cells in the anterior cingulate cortex and dorsolateral septum in this group. Thus we concluded that Wistar rats that consumed moderate doses of alcohol voluntarily and chronically showed a discreet anxiolytic effect in behavior, and a hypodopaminergic and hyperCRFergic neurochemical condition, which together are strong inducers of alcohol consumption predisposing to the development of alcohol use disorder (AUD).

A single ovarian stimulation, as performed in assisted reproductive technologies, can modulate the anxiety-like behavior and neuronal activation in stress-related brain areas in rats.

Abstract
Infertility affects about 8 to 12% of couples of childbearing age around the world, and is recognized as a global public health issue by the WHO. From a psychosocial perspective, infertile individuals experience intense psychological distress, related to emotional disorders, which have repercussions on marital and social relationships. The symptoms persist even after seeking specialized treatment, such as assisted reproductive technologies (ART). While the stress impact of ART outcome has been comprehensively studied, the role of supraphysiological concentrations of gonadal hormones on stress response, remains to be elucidated. This study aimed to evaluate the effect of a single ovarian stimulation on the stress response in rats. To mimic the context of ART in rodents, female rats were submitted to the superovulation (150 UI/kg of PMSG and 75 UI/kg of hCG) and then to psychogenic stress (restraint stress for 30 min/day, repeated for three days). Anxiety-like behavior was evaluated in the elevated plus-maze, and neuronal activation in the stress-related brain areas assessed by Fos protein immunoreactivity. Corticosterone, estradiol, progesterone and corpora lutea were quantified. Data were analyzed using Generalized Linear Model (GzLM). Our findings indicate anxiolytic-like and protective effects of supraphysiological concentrations of gonadal hormones induced by a single ovarian stimulation on stress response. An activation of hypothalamus-pituitary-adrenal response inhibitory pathways, with participation of the prefrontal cortex, basomedial amygdala, lateral septum, medial preoptic area, dorsomedial and paraventricular hypothalamus, was detected.
