Age- and Sex-Specific Regulation of Serine Racemase in the Retina of an Alzheimer's Disease Mouse.

Purpose: Changes associated with Alzheimer's disease (AD) may have measurable effects on the retina, which may facilitate early detection due to the eye's accessibility. Retinal pathology and the regulation of serine racemase (SR) were investigated in the retinas of APP(SW)/PS1(∆E9) mice.

Methods: SR in the retinas and the content of D-serine in the aqueous humor were analyzed.

Complex management of GS (Good's syndrome) with persistent COVID-19 infection and polymicrobial infections: A case report.

This case report highlights the diagnostic and therapeutic complexities faced by a 56-year-old female with Good's syndrome (GS), who presented with persistent Coronavirus Disease 2019 (COVID-19) infection alongside spp, , and co-infection, which collectively contributed to severe pulmonary involvement. The report further emphasizes a multifaceted treatment approach, incorporating antivirals, antifungals, antimicrobials, immunoglobulins, and antifibrotic therapy, which ultimately led to an improvement in the patient's condition. It underscored the intricate challenges of managing immunocompromised patients with multiple concurrent infections.

Photocatalytic [3 + 2]-annulation sodium tetraarylborate: a fundamental approach for synthesizing 1,4,2-diazaborole analogs.

Substantial advancements have been achieved in the field of photocatalytic borylation utilizing 4c-7e Lewis base-boryl radicals. However, the utilization of 3c-5e neutral boryl radicals for C-B bond formation remains relatively underexplored due to their inherent instability. In this study, we successfully demonstrated the direct construction of C-B bonds using sodium tetraarylborate as a key reagent.

Catalytic-independent functions of the Integrator-PP2A complex (INTAC) confer sensitivity to BET inhibition.

Chromatin and transcription regulators are critical to defining cell identity through shaping epigenetic and transcriptional landscapes, with their misregulation being closely linked to oncogenesis. Pharmacologically targeting these regulators, particularly the transcription-activating BET proteins, has emerged as a promising approach in cancer therapy, yet intrinsic or acquired resistance frequently occurs, with poorly understood mechanisms. Here, using genome-wide CRISPR screens, we find that BET inhibitor efficacy in mediating transcriptional silencing and growth inhibition depends on the auxiliary/arm/tail module of the Integrator-PP2A complex (INTAC), a global regulator of RNA polymerase II pause-release dynamics.

Integrating genetics and transcriptomics to characterize shared mechanisms in digestive diseases and psychiatric disorders.

Digestive and psychiatric disorders tend to co-occur, yet mechanisms remain unclear. Leveraging genetic and transcriptomic data integration, we conduct multi-trait analysis of GWAS (MTAG) and weighted gene co-expression network analysis (WGCNA) to explore shared mechanism between psychiatric and gastrointestinal disorders. Significant genetic correlations were found between these disorders, especially in irritable bowel syndrome (IBS), gastroesophageal reflux disease (GERD), depression (DEP), and neuroticism (NE).
