Tumor‐Derived Exosomal piR‐hsa‐28212 Promotes Lymphatic Metastasis in Breast Cancer

Cancer Science, EarlyView.
Breast cancer–derived exosomal piR‐hsa‐28212 promotes lymphangiogenesis and lymph node metastasis by activating VEGFC/VEGFR3 signaling. It stabilizes TBX1 mRNA in lymphatic endothelial cells and METTL3 protein in tumor cells, enhancing VEGFR3 expression and VEGFC secretion.

SERPINE1 Alternative Polyadenylation Influences Gastric Cancer Prognosis via N6‐Methyladenosine Modification

Cancer Science, EarlyView.
Multi‐omics integration of the transcriptomic APA landscape and m6A modifications identifies key prognostic genes. Their biological functions and molecular mechanisms in promoting tumor progression are comprehensively validated through in vitro assays. ABSTRACT Alternative polyadenylation (APA) and N6‐methyladenosine (m6A) methylation are critical post‐

YBX1 Promotes Malignant Progression of HNSCC via Stabilizing NSUN2‐m5C Modified ATF4 mRNA

Cancer Science, EarlyView.
The diagram depicts the core axis and the key finding: “Targeting YBX1/NSUN2 abrogates HNSCC progression”. Within left‐sided HNSCC cells, NSUN2 mediates m5C methylation on the CDS of ATF4 mRNA; YBX1 then specifically recognizes and binds this modified site, augmenting ATF4 mRNA stability, which ultimately promotes cancer cell proliferation, migration ...

AI techniques have facilitated the understanding of epitranscriptome distribution

Cell Genomics
N6-methyladenosine (m6A), the most prevalent internal mRNA modification in higher eukaryotes, plays diverse roles in cellular regulation. By incorporating both sequence- and genome-derived features, Fan et al.1 designed a novel Transformer-BiGRU ...

m6A‐Mediated Stabilization of MRPS23 Drives NSCLC Progression Via HSPA8 and ERK Signaling Modulation

Cancer Science, EarlyView.
MRPS23 mRNA is m6A‐methylated by WTAP and stabilized by IGF2BP3, leading to increased MRPS23 protein. MRPS23 physically interacts with HSPA8, and this interaction is functionally associated with activation of the RAS–RAF–MEK–ERK pathway, ultimately promoting NSCLC cell proliferation and tumor progression.

YTHDF3 Enhances Osteogenic Differentiation of Bone Marrow Mesenchymal Stem Cells in Osteoporosis by Promoting TBX19 Expression

Cell Proliferation, EarlyView.
In this study, OP‐BMSCs were successfully isolated from OVX osteoporotic rats. Mechanistic investigations revealed that the RNA‐binding protein YTHDF3 significantly upregulates Tbx19 expression by enhancing the stability of Tbx19 mRNA. Elevated Tbx19 levels, in turn, activate key osteogenic molecules, effectively promoting the differentiation of OP ...

Targeting m6A Modifications Regulating Ferroptosis Offers Novel Therapy in Diseases

Cell Proliferation, EarlyView.
m6A RNA modification regulates ferroptosis by balancing iron metabolism, lipid peroxidation, and antioxidant defenses. Dysregulated m6A signaling disrupts pro‐ and anti‐ferroptotic factors, leading to excess ROS, Fe3+ accumulation, and lipid peroxidation–driven cell death. Targeting m6A‐mediated ferroptotic regulation represents a promising therapeutic

Proteostasis of organelles in aging and disease

The FEBS Journal, EarlyView.
Cells rely on regulated proteostasis mechanisms to keep their internal compartments functioning properly. When these mechanisms fail, damaged proteins accumulate, disrupting organelles, such as the nucleus, mitochondria, endoplasmic reticulum, Golgi, and lysosomes, as well as membraneless organelles, such as stress granules, processing bodies, the ...

GSK3α‐mediated regulation of the RNA demethylase fat mass and obesity‐associated protein (FTO) during murine spermatogenesis

The FEBS Journal, EarlyView.
FTO regulates mRNA stability and translational efficiency through its m6A‐demethylation activity. GSK3 functions as an upstream regulator of FTO, leading to its inhibition via phosphorylation. In male germ cells, FTO activity is kept in check by GSK3α.

Epigenetic Regulation in the Pathogenesis of Periodontitis

Journal of Periodontal Research, EarlyView.
The aim of this narrative literature review was to identify epigenetic marks associated with periodontitis and to place them in a biological context. The literature was reviewed based on pre‐defined criteria. Cell type specific chromatin and mRNA modifications were included.
