- Primary cutaneous T-lymphomas (CTCL), particularly in their early stages, frequently present with clinical and histopathologic features that overlap with atopic dermatitis (AD) and psoriasis, contributing to diagnostic delay and ineffective, or even deleterious, treatment approaches. Thus, minimally invasive molecular tests capable of distinguishing CTCL from benign inflammatory dermatoses are urgently needed. - Source: PubMed

This review focuses on testicular-level evidence regarding the effects of microplastics, bisphenol compounds, and air pollution on male reproductive health, with an emphasis on spermatogenic and testicular somatic cell mechanisms. Microplastics have been detected in human testicular tissue, with a causal pathway established linking gut microbiota dysbiosis, immune activation, and blood-testis barrier disruption. Bisphenol A substitutes show comparable or greater reproductive toxicity than BPA, with BCAT1-mediated ferroptosis identified as a novel testicular injury mechanism. For air pollution, spermatogenesis stage I (70-90 days prior to semen collection) has been pinpointed as the critical PM2.5 exposure vulnerability window, with metal constituents of traffic-derived PM2.5 as the primary toxicity drivers. Future research should prioritize prospective cohort studies and clinical intervention trials targeting these emerging mechanistic pathways. - Source: PubMed

Guo AndongLu YiGuo YeLi Hongjun - Myofibroblasts are the cells responsible for collagen production, leading to tissue fibrosis. Because 20.5% of the total amino acids in collagen are proline, myofibroblasts must acquire a well-developed proline-producing mechanism during their differentiation. However, the detailed mechanism for myofibroblasts to acquire and keep the developed proline biosynthesis machinery remains obscure. Here, we show branched-chain amino acid transaminase 1 (Bcat1) is up-regulated in a substantial subset of Postn-expressing proto-myofibroblast-like fibroblasts, transitional cells en route to fully differentiated myofibroblasts, as well as in myofibroblasts in the fibrotic heart and liver of mice and humans and promotes the proline production. The branched-chain amino acid (BCAA) production by BCAT1 promotes SMAD3 phosphorylation via HDAC5 phosphorylation at Ser488, thereby enhancing SMAD3-dependent transcription of proline biosynthesis-related genes, Aldh18a1, Pycr1, and Eprs, in proto-myofibroblast-like fibroblasts and myofibroblasts. In BCAT1-deficient mice, expression of proline biosynthesis-related genes is significantly attenuated in their hearts after myocardial infarction, resulting in decreased cardiac fibrosis. Moreover, BCAT1 inhibitor treatment of mice with myocardial infarction reduces cardiac fibrosis. Our results identified a BCAT1-mediated pathway that promotes collagen production via proline biosynthesis regulation in proto-myofibroblast-like fibroblasts and myofibroblasts, which may provide a therapeutic target for cardiac fibrosis. - Source: PubMed

Using datasets from The Cancer Genome Atlas and the Genotype-Tissue Expression project, we analyzed BCAT1 expression, prognosis, genetic alterations, immune infiltration, and functional enrichment across 33 cancer types. The primary endpoints were overall survival (OS) and disease-free survival (DFS). Statistical significance was primarily defined as P < .05. For analyses involving multiple correlations across cancer and immune cell types, the false discovery rate < 0.05 was applied. BCAT1 was significantly upregulated in most malignancies, and high expression was associated with worse OS and DFS in multiple cancer types. BCAT1 expression correlated with reduced CD8+ T cell infiltration and increased cancer-associated fibroblast accumulation across several tumors. Enrichment analyses suggested BCAT1 involvement in RNA metabolism and intracellular protein processing. BCAT1 was significantly upregulated in most malignancies, and high expression was associated with worse OS and DFS in multiple cancer types, including adrenocortical carcinoma (hazard ratio = 6.3) and lower-grade glioma (hazard ratio = 2.6) (all log-rank P < .05), highlighting its potential as a pan-cancer biomarker and therapeutic target. The present findings are associative and require further experimental and external validation. - Source: PubMed

To address the limitation, this study proposes a novel multi-target free DNA methylation model and evaluated its risk stratification performance for CRC in high-risk populations. - Source: PubMed
