- 5-Methylcytosine (mC) is a widespread mRNA modification that regulates gene expression and is frequently dysregulated in cancer. Here, we used phage display to identify peptides that bind an NSUN2 consensus RNA sequence in either its unmodified (UN2-RNA) or mC-modified (MN2-RNA) form. A single peptide, un2p1 (TDYSTHRLSHSL), was selectively enriched against both targets. Biophysical analyses demonstrated that un2p1 binds this RNA sequence with high affinity and that mC incorporation reduces binding by approximately ninefold, indicating that cytidine methylation acts as a biochemical switch for peptide-RNA recognition. Sequence alignments mapped un2p1 to a conserved structural loop and catalytic domain region within NSUN2, suggesting that the peptide functions as a molecular mimic of the endogenous RNA-recognition interface. In A549 lung adenocarcinoma cells, un2p1 treatment reduced global mC levels and downregulated the oncogenic chaperonin CCT5, consistent with disruption of NSUN2-dependent Wnt/β-catenin signaling. These effects were attenuated in non-malignant HEK293 cells, which exhibited a compensatory increase in mC levels and preserved viability. Together, these findings identify un2p1 as a sequence-specific, methylation-sensitive RNA-binding peptide that modulates the mC epitranscriptome and selectively impairs lung cancer cell viability, highlighting a substrate-centric strategy for targeting NSUN2-mediated oncogenic pathways. - Source: PubMed

Kang KuoWei LinfengLi XuanxuanWang ShalongHuang ChanghaoWu Zhiwei - Heart failure with preserved ejection fraction (HFpEF) is an increasingly common form of heart failure (HF) that is best understood as a systemic, multiorgan syndrome rather than a disease of left-ventricular filling alone. This review has three specific aims: first, to synthesize genetic and molecular pathways that are most relevant to non-ischemic HFpEF; second, to distinguish HFpEF-enriched mechanisms from evidence extrapolated from ischemic cardiomyopathy or HFrEF; and third, to consider translational implications for populations with high consanguinity, including the Kingdom of Saudi Arabia. The available evidence indicates that chronic inflammatory signaling involving CCL2, CCL5, TLR3, PTGS2/COX-2, IL-6/JAK/STAT3, NF-kB, and NLRP3 acts upstream of endothelial dysfunction, nitric-oxide/cGMP/PKG impairment, mitochondrial reactive oxygen species generation, and fibroblast activation. Extracellular-matrix regulators including ASPN, COL1A1, and MMP2 then amplify collagen deposition and myocardial stiffness, whereas mitochondrial genes and proteins such as ATP5C1 contribute to impaired oxidative phosphorylation, reduced ATP reserve, defective fatty-acid oxidation, and blunted mitophagy. Protein-quality-control pathways involving HSP90AA1, CCT2/CCT5, PSMA3, and stress-responsive STAT3 further link metabolic stress to proteotoxic injury. Epigenetic mechanisms, including DNA methylation and microRNAs such as miR-155, miR-1297, and miR-4649-3p, add a regulatory layer that may improve risk stratification but remains insufficiently validated for routine clinical use. In high-consanguinity settings, recessive cardiomyopathy variants can cluster in families and contribute to earlier NIHF presentations; however, population-level HFpEF-specific variant frequencies remain limited, and findings from HFrEF or dilated cardiomyopathy should be interpreted as candidate pathway evidence rather than definitive HFpEF markers. Translationally, SGLT2 inhibitors, mineralocorticoid-receptor antagonism, biomarker panels, and structured genetic evaluation provide the most clinically actionable bridge from molecular mechanisms to precision HFpEF care. - Source: PubMed

Abou Al-Saud Sara - Inferring gene regulatory networks (GRNs) from single-cell RNA sequencing (scRNA-seq) data is fundamentally challenged by severe data sparsity, where pervasive dropout events obscure true regulatory signals and compromise the reliability of downstream inference. Existing supervised methods, while leveraging prior network structures, remain highly susceptible to this noise due to their end-to-end learning paradigm. To address this bottleneck, we propose SGMHA, a novel two-stage framework that decouples representation learning from link prediction. Specifically, SGMHA first employs a self-supervised graph masked autoencoder (GraphMAE) to learn robust gene representations by reconstructing randomly masked expression values, thereby mitigating sparsity-induced distortions. Subsequently, an MHA (multi-head attention)-based fine-tuning module integrates these pre-trained representations with raw expression data to accurately infer directed regulatory links. Extensive benchmarking across seven scRNA-seq datasets demonstrates that SGMHA consistently outperforms eight state-of-the-art methods in both area under the receiver operating characteristic curve (AUROC) and area under the precision-recall curve (AUPRC). Applying SGMHA to breast cancer metastasis revealed context-specific GRNs and identified 26 high-confidence candidate drivers. Among these, six (NDUFAF4, ENY2, CCT5, PGK1, DCTPP1, and H2AFZ) were validated as prognostic biomarkers, with their mechanistic roles in metastatic adaptation detailed through multi-omics integration. Collectively, SGMHA provides an accurate, scalable, and biologically interpretable tool for GRN inference, holding strong promise for biomarker discovery in complex diseases. - Source: PubMed
