Uterine angiomyofibroblastoma in a domestic cat: A need of precise diagnosis for proper perioperative management.

Angiomyofibroblastoma (AMFB) is rarely reported in humans as well as domestic animals, especially in the female genital tract. This painless tumour is characterised by the proliferation of spindle or ovoid tumour cells with myofibroblastic differentiation, which often cluster around thin-walled blood vessels. This report presents a case of feline AMFB for the first time.

Protein Microplastic Coronation Complexes Trigger Proteome Changes in Brain-Derived Neuronal and Glial Cells.

The extensive distribution of microplastics (MPs) in the environment and their food chain contamination urgently necessitates a deeper understanding of their molecular-level impact on physiological responses. This study employed a mass spectrometry-based proteomics approach to investigate the potential risks, mechanisms of associated cellular processes, and biological reactions to preformed protein-MPs coronation and intact MPs using brain-derived neuronal and glial cells. Our findings indicate that MPs can adsorb proteins and form a heterogeneous corona layer when interacting with biological fluids such as serum.

Research approaches for exploring the hidden conversations of G protein-coupled receptor transactivation.

G protein-coupled receptor (GPCR) signaling is a crucial physiological mechanism that encompasses a wide range of signaling phenomena. Although traditional GPCR signaling involves G protein or arrestin-related activation, other modes such as biphasic activation, dimer or oligomeric activation, and transactivation have also been observed. Herein, we focus on the increasingly recognized process of GPCR-transactivation.

Identification of potential Abl kinase inhibitors using virtual screening and free energy calculations for the treatment of chronic myeloid leukemia.

The NLRP3 inflammasome in microglia regulates repetitive behavior by modulating NMDA glutamate receptor functions.

Neuroinflammation is a well-established risk factor for various neurological disorders and cognitive decline. However, the precise molecular mechanisms linking inflammation with neuropsychiatric symptoms remain unclear. Here, using NLRP3 (NOD-like receptor family, pyrin domain-containing protein 3) conditional knockin (cKI) mice harboring a D301N point mutation originating in patients with autoinflammatory diseases, we found that activation of the NLRP3 inflammasome by administration of lipopolysaccharide induced anxiety-like and repetitive behaviors frequently found in patients with neuropsychiatric disorders, as well as increasing NMDAR (N-methyl-D-aspartate receptor)-mediated excitatory synaptic functions in the medial prefrontal cortex of mice.

PRPF4 Knockdown Suppresses Glioblastoma Progression the p38 MAPK and ERK Signaling Pathways.

Background/aim: Pre-mRNA processing factor 4 (PRPF4), a core protein of U4/U6 small nuclear ribonucleoproteins (snRNPs), is crucial for maintaining their structure by interacting with PRPF3 and Cyclophilin H. Beyond its role in splicing, PRPF4 has been implicated in cell survival, apoptosis, and oncogenesis. Although PRPF4 mutations have been associated with retinitis pigmentosa, its role in glioblastoma (GBM) remains unclear.

Disrupted intestinal mucosal barrier mediated by alcohol consumption aggravates systemic microplastic accumulation.

Waste plastics are degraded into microplastics (MPs), which are easily accumulated in the human body through digestive tracts, via the food chain. Alcohol is a widely consumed chemical throughout the world with the ability to alter the intestinal barrier. For this reason, this study was aimed to investigate exact relevance between alcohol consumption and organ distributions of MPs in an ethanol feeding animal model characterized by disrupted intestinal mucosal barriers.

Veratramine Inhibits the Cell Cycle Progression, Migration, and Invasion via ATM/ATR Pathway in Androgen-Independent Prostate Cancer.

Prostate cancer (PC) is the second leading cause of cancer-related death among men. Treatment of PC becomes difficult after progression because PC that used to be androgen-dependent becomes androgen-independent prostate cancer (AIPC). Veratramine, an alkaloid extracted from the root of the genus, has recently been reported to have anticancer effects that work against various cancers; however, its anticancer effects and the underlying mechanism of action in PC remain unknown.

A preliminary study about the potential risks of the UV-weathered microplastic: The proteome-level changes in the brain in response to polystyrene derived weathered microplastics.

The growing use of plastic materials has resulted in a constant increase in the risk associated with microplastics (MPs). Ultra-violet (UV) light and wind break down modify MPs in the environment into smaller particles known as weathered MPs (WMPs) and these processes increase the risk of MP toxicity. The neurotoxicity of weathered polystyrene-MPs remains unclear.
