Molecular Mechanisms of Rett Syndrome: Emphasizing the Roles of Monoamine, Immunity, and Mitochondrial Dysfunction.
Cells
December 2024
Department of Neurobiology, University of Alabama at Birmingham, Birmingham, AL 35294, USA.
Rett syndrome (RTT), which predominantly affects females, arises in most cases from mutations in the () gene. When MeCP2 is impaired, it disrupts the regulation of numerous genes, causing the production of dysfunctional proteins associated with various multi-systemic issues in RTT. In this review, we explore the current insights into molecular signaling related to monoamines, immune response, and mitochondrial function, and their implications for the pathophysiology of RTT.

Background: Changan Granule (CAG) is a drug product developed from a traditional Chinese medicine (TCM) empirical prescription for diarrhea-predominant irritable bowel syndrome (IBS-D). The action mechanism and effective compounds of CAG in the treatment of IBS-D are not well understood.
Purpose: This study aimed to investigate the effectiveness, action mechanism and effective compounds of CAG for treating IBS-D.
Biotin Mitigates Alcohol Withdrawal-Induced Anxiety and Depression by Regulating Serotonin Metabolism, BDNF, Inflammation, and Oxidative Stress in Rats.

Department of Biology and Microbiology, Faculty of Medical Laboratory Technology, Khatam Al-Nabieen University, Kabul, Afghanistan.
Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.
Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.
Acute administration of NLX-101, a Serotonin 1A receptor agonist, improves auditory temporal processing during development in a mouse model of Fragile X Syndrome.

Graduate Neuroscience Program, University of California, Riverside, CA, USA.
Background: Fragile X syndrome (FXS) is a leading known genetic cause of intellectual disability and autism spectrum disorders (ASD)-associated behaviors. A consistent and debilitating phenotype of FXS is auditory hypersensitivity that may lead to delayed language and high anxiety. Consistent with findings in FXS human studies, the mouse model of FXS, the Fmr1 knock out (KO) mouse, shows auditory hypersensitivity and temporal processing deficits.

Gut Pathog
December 2024
Department of Pharmacology, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal, Karnataka, 576104, India.
Background: Maintaining gut microbial homeostasis is crucial for human health, as imbalances in the gut microbiota (GM) can lead to various diseases, including metabolic syndrome (MS), exacerbated by the use of antipsychotic medications such as olanzapine (OLZ). Understanding the role of the GM in OLZ-induced MS could lead to new therapeutic strategies. This study used metagenomic analysis to explore the impact of OLZ on the GM composition and examined how probiotics can mitigate its adverse effects in a rat model.
