Skin diseases encompass a diverse range of conditions with significant psychological and physiological impacts. N6-methyladenosine (m6A) RNA methylation is a key epitranscriptomic modification that regulates gene expression by influencing RNA stability, splicing, translation, export, and degradation. Recent studies have highlighted the crucial role of m6A modification in the pathogenesis and progression of various skin diseases. M6A modification affects critical biological processes of the skin, such as inflammation, immune response, and cellular aging. This review systematically explores the landscape of m6A modification in non-tumor skin diseases, elucidating its regulatory roles and therapeutic implications, including wound healing, scar and keloid, skin aging, psoriasis, systemic lupus erythematosus, acne vulgaris, rosacea, chronic actinic dermatitis, and scleroderma. The intricate mechanisms of m6A modification can lead to the development of novel diagnostic biomarkers and therapeutic strategies, ultimately improving patient outcomes.

Floods constitute one of the most widely described natural phenomena worldwide, and their frequency is increasing due to the consequences of climate change. Floods pose risks to the affected populations, including an increase in communicable diseases mainly due to population displacement and overcrowding, deficiencies in hygiene and dietary measures and difficulties accessing health care. The most frequently reported infectious diseases in the context of these disasters are gastrointestinal and respiratory diseases and diseases resulting from wound infection.

Purpose: We developed software that can analyze central lung distance (CLD) and central skin distance (CSD) in deep inspiration breath hold (DIBH) irradiation and verified the reproducibility of the DIBH irradiation method in our hospital.

Methods: CLD and CSD were analyzed using In-house software using cine images acquired during treatment; intra- or inter-fractional motion was calculated from the obtained data and compared with other reports using systematic error (ΔΣ) and random error (Δσ).

Results: The ΔΣ and Δσ were 1.

Fc-mediated immune stimulating, pro-inflammatory and antitumor effects of anti-HER2 IgE against HER2-expressing and trastuzumab-resistant tumors.

J Immunother Cancer

March 2025

St. John's Institute of Dermatology, School of Basic & Medical Biosciences & KHP Centre for Translational Medicine, King's College London, London, UK

Background: Anti-human epidermal growth factor receptor 2 (HER2) IgG1-based antibody therapies significantly improve cancer prognosis, yet intrinsic or acquired resistance to fragment antigen-binding (Fab)-mediated direct effects commonly occurs. Most resistant tumors retain antigen expression and therefore remain potentially targetable with anti-HER2 therapies that promote immune-mediated responses. Tumor-antigen-specific IgE class antibodies can mediate powerful immune cell-mediated effects against different cancers and have been shown to activate IgE Fc receptor-expressing monocytes.
