Atypical antipsychotics including aripiprazole (ARI) or enriched environment can ameliorate disturbances connected to PTSD. This study was aimed to reveal whether ARI treatment supplemented by improved living conditions, i.e. toy rotation (TR), will ameliorate behavioral outcomes and reverse assumed changes in neurogenesis more effectively than sole ARI treatment in a single prolonged stress (SPS) animal model of PTSD. <b>Methods.</b> Adult male Sprague-Dawley rats weighing 176-200 g were randomly assigned to 5 experimental groups: (1) VEH - control non-stressed animals injected with vehicle (VEH, 2% Tween 20 in the saline); (2) SPS - animals exposed to SPS injected with VEH; (3) SPS+ARI - SPS animals injected with ARI (5 mg/kg in VEH); (4) SPS+TR - SPS animals exposed to TR and injected with VEH; (5) SPS+ARI+TR - SPS animals exposed to TR and injected with ARI. Animals in TR groups were housed in the standard cages with two toys per cage, which were replaced every other day. Elevated plus maze (EPM), open field (OF), and novel object recognition test (NOR) were used to assess the anxiety-like behavior and learning/memory. Changes in gene and protein expression of selected neurogenic markers (BDNF, GFAP, Sox2, DCX, NeuN) and transcription factors (ΔFosB, pCREB) in the subventricular zone (SVZ) and the gyrus dentatus (GD) of the hippocampus were determined by semi-quantitative real-time PCR and immunohistochemistry, respectively. <b>Results.</b> SPS animals showed increased anxiety-like behavior that was suppressed by TR and ARI+TR treatment combination. Although SPS did not affect the expression of studied neurogenic markers, ARI treatment increased the expression of doublecortin in the SVZ and TR increased expression of NeuN in the GD of PTSD-like animals. TR enhanced ARI effect on NeuN expression in the SVZ. SPS induced increase of ΔFosB positive cells, which was reduced by ARI+TR complementary treatment. <b>Conclusions.</b> Obtained results indicate that TR, in contrary to ARI, suppressed the anxiety-like behavior in PTSD-like animals.

The present study aims to investigate the regulation of the IRS2 gene expression in normal human astrocytes and U87MG glioblastoma cells by hypoxia and ER stress in the context of the native stress hormone hydrocortisone, which is widely used for the co-treatment of glioblastoma. &lt;b&gt;Methods.&lt;/b&gt; The normal human astrocytes (line NHA/TS) and U87MG glioblastoma cells were used.

Recent studies have highlighted the critical role of the circadian rhythm, the body's internal biological clock, in the pathogenesis of diabetes. The circadian system regulates glucose metabolism, insulin secretion, and energy homeostasis. Modern lifestyle factors such as sleep disturbances shift work and irregular eating patterns disrupt circadian rhythms promoting insulin resistance and glucose intolerance. At the molecular level, mutations or altered expression of clock genes contribute to diabetes development. Clinical and experimental evidence suggests that maintaining the circadian integrity can reduce the diabetes risk and the chronotherapy time-based treatment approaches may enhance the therapeutic efficacy. The future advances including genetic profiling, AI-assisted monitoring and microbiota modulation hold promise for improved diabetes management. This review comprehensively examines the relationship between diabetes and circadian disruption emphasizing the importance of circadian biology in preventing and treating the metabolic diseases.</p>","PeriodicalId":11650,"journal":{"name":"Endocrine regulations","volume":"59 1","pages":"206-216"},"PeriodicalIF":0.0,"publicationDate":"2025-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145488231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
