- Protein arginine methyltransferase 3 (PRMT3) is a key member of the PRMT family that catalyzes the arginine methylation of proteins, thereby modulating their structure, localization, or interactions and influencing essential physiological processes, such as cell growth and signal transduction. Its dysregulation is closely associated with tumorigenesis and neurological disorders. PRMT3 is critically involved in cellular processes, such as cell growth, invasion, and apoptosis, making it a promising target for drug discovery. In this review, we summarized the structure and biological functions of PRMT3, particularly the mechanism of action in human diseases. We also evaluated the co-crystal structure of PRMT3 inhibitors. Furthermore, we examined the recent advancements in the development of PRMT3 modulators, including isoform-selective and partially isoform-selective PRMT3 inhibitors as well as PRMT3-targeting PROTACs, from a rational design perspective. Finally, we discussed the existing challenges and future directions in PRMT3-targeted drug discovery. - Source: PubMed

Yu DongminHe KangMai CunjunLi Meifang - Protein arginine methyltransferases are key epigenetic regulators and promising targets for cancer therapy. PRMT4 plays an important role in transcriptional regulation and tumor progression, yet selective inhibition remains challenging because type I PRMTs share highly conserved catalytic sites. The success of allosteric inhibitors targeting PRMT3 and PRMT6 suggests that selective modulation through regulatory sites outside the catalytic pocket may also be feasible for PRMT4. Motivated by this rationale, we investigated whether PRMT4 undergoes conformational transitions between active and inactive states and whether it contains allosterically targetable pockets capable of regulating its enzymatic activity. Using an integrated computational strategy, we characterized the conformational dynamics and allosteric regulation mechanisms of PRMT4. Structural analysis identified a molecular switch involving order and disorder transitions of the N terminal helices that governs the active inactive transition. Free energy landscape analysis supported that this transition is thermodynamically accessible. We identified a PRMT3 like allosteric pocket, Cavity 1, whose targeting is predicted to disrupt inter chain communication and impair cofactor binding and active site organization. Dynamic residue network analysis further supported Cavity 1 as a functional allosteric site. We also identified a PRMT4 specific pocket, Cavity 2, with a distinct selectivity profile. These findings validate the active inactive switch and identify two druggable allosteric sites. Although experimental validation is required, this work provides a computational framework for the rational design of PRMT4 selective allosteric inhibitors. - Source: PubMed

Zhang XiHao YanglinHan DongJin XinShang XiaokeZhang LiGan ZhengYe WeicongWang SongLi XiaohanLi RanZheng KexiaoLiu YinghuanZou ZifengTao ZetongLi YilongWang YongjunXia JiahongWu Jie - Age-related macular degeneration (AMD) is a leading cause of blindness in developed countries and a growing global health concern. The multifactorial nature of AMD calls for integrative multi-omics approaches. We summarize studies employing multi-omics in AMD. A comprehensive search in PubMed and Scopus databases identified 561 records with multi-omics criteria, of which duplicates, unrelated and unavailable articles were excluded, resulting in 33 reports. Quality was assessed following the Office of Health Assessment and Translation (OHAT) method, and data was synthesized through standardized evidence tables. Across the reviewed reports, multi-omics approaches were applied to non-clinical and clinical samples, including ocular and systemic fluids. Methodological trends included the widespread use of causal inference approaches (e.g., Mendelian randomization and Bayesian colocalization) and increasing adoption of spatial and single-cell resolution techniques. Converging molecular patterns consistently suggested inflammation, complement activation, angiogenesis, lipid dysregulation, and mitochondrial dysfunction as key processes underlying AMD. Integration of genetic risk with proteomic and metabolomic alterations, enabled the identification of candidate diagnostic and prognostic biomarkers such as carboxyethylpyrrole and PRMT3. Additionally, this review revealed opportunities for personalized medicine in AMD patient stratification, improvement of prediction models, and therapeutic personalization; however, heterogeneity was noted across studies, particularly regarding sample source (systemic vs. ocular), analytical platforms, integration strategies, and ancestry representation. Despite this variability, this review illustrates how integrating multiple omics layers provides a comprehensive and multidimensional understanding of AMD pathology, advancing research towards better diagnosis, prognosis, and therapeutics for these patients. - Source: PubMed

Castro-Fernández Diana CarolinaCañizo-Outeriño AntonioCuartero-Martínez AndreaGil-Martinez MariaMondelo-Garcia CristinaGonzález-Barcia MiguelÁlvarez-Barrios AnaFernández-Ferreiro Anxo - Obesity impairs metabolic flexibility-the capacity to adapt to fluctuating energy demands. Emerging evidence suggests that dietary interventions, particularly time-restricted feeding (TRF), may help restore this flexibility. In this study, we demonstrate that feeding upregulates PRMT3 and asymmetric dimethylarginine (ADMA)-containing proteins via insulin-pAKT signaling, while fasting reduces their expression. Pharmacological inhibition of PRMT3 attenuates diet-induced obesity (DIO) and enhances adipocyte glycolysis in male mice. Mechanistically, PRMT3 drives the expression of citrate transporter SLC25A1 during feeding through direct arginine methylation. A 16:8 TRF regimen normalizes PRMT3 and ADMA levels while suppressing SLC25A1 expression. Notably, PRMT3 inhibition recapitulates the metabolic benefits of 16:8 TRF and improves metabolic flexibility. Furthermore, adipocyte-specific deletion of Slc25a1 in male mice protects against DIO and enhances insulin sensitivity. Collectively, these findings identify PRMT3-mediated arginine methylation in vWAT as a nutrient-responsive regulatory axis that impairs metabolic flexibility in obesity, which is a potential therapeutic target. - Source: PubMed
