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.

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 ...

Cannabinoids shift the basal ganglia microRNA m6A methylation profile towards an anti-inflammatory phenotype in SIV-infected rhesus macaques

Communications Biology
Epitranscriptomic modifications [N6-methyladenosine (m6A)] regulate various diseases, including cancer and inflammation. Despite their functional relevance in neural development and differentiation, the role of m6A modifications in HIV neuropathogenesis ...

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 ...

Lysine l‐Lactylation: Bridging Metabolism, Chromatin and Disease

Cell Proliferation, EarlyView.
Enzymatic regulation of KL‐la. The enzymatic regulation of KL‐la involves two distinct pathways for L‐lactate accumulation: intracellular production through glycolysis‐derived pyruvate conversion by lactate dehydrogenase (LDH) or direct cellular uptake via monocarboxylate transporters (MCTs). These L‐lactate pools fuel two distinct lactylation pathways—

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 ...

Contrasting effects of different molecular crowding environments on base‐pair opening/closing dynamics of DNA triplex structures

The FEBS Journal, EarlyView.
Base‐pair opening and closing regulate nucleic‐acid structure, stability, and function, but how these motions behave under intracellular molecular crowding remains unclear. Using NMR, we quantified these dynamics in a DNA triplex under two crowder‐reconstituted environments that mimic cellular crowding.

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.

Understanding exosomes in regenerative dentistry

Periodontology 2000, EarlyView.
Abstract Background Regenerative dentistry is shifting from cell‐based strategies to cell‐free biologics capable of orchestrating intricate tissue repair. Exosomes, nanosized extracellular vesicles carrying bioactive molecular payloads, have emerged as central modulators of intercellular communication.

Hypoxia and hypercapnia elicit overlapping but distinct skeletal muscle toxicities

The Journal of Physiology, EarlyView.
Abstract figure legend Hypoxia and hypercapnia cause overlapping skeletal muscle phenotypes, including atrophy, change in myofibre metabolic profile and myogenic response to injury. Both signals operate via distinct cellular pathways. Abstract Skeletal muscle dysfunction is strongly associated with elevated mortality in acute and chronic pulmonary ...
