MAPK Inhibitor‐Tolerant Persister Cells in Melanoma: Mechanisms and Therapeutic Vulnerabilities

Cancer Science, EarlyView.
Melanoma response to MAPK inhibition progresses from drug‐sensitive cells to drug‐tolerant persister states, which enable survival through adaptive signaling, metabolic rewiring, and phenotypic plasticity. These persister cells serve as an intermediate reservoir from which resistant tumors ultimately emerge. ABSTRACT Though major advancements have been

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.

Regulatory effect of N6-methyladenosine on tumor angiogenesis

Frontiers in Immunology
Previous studies have demonstrated that genetic alterations governing epigenetic processes frequently drive tumor development and that modifications in RNA may contribute to these alterations. In the 1970s, researchers discovered that N6-methyladenosine (m6A) is the most prevalent form of RNA modification in advanced eukaryotic messenger RNA (mRNA) and

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 ...

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.

CRISPR/dCas13(Rx) Derived RNA N6‐methyladenosine (m6A) Dynamic Modification in Plant

Advanced Science
N6‐methyladenosine (m6A) is the most prevalent internal modification of mRNA and plays an important role in regulating plant growth. However, there is still a lack of effective tools to precisely modify m6A sites of individual transcripts in plants. Here,
