microRNA‐mediated control of cell fate specification and patterning in Marchantia polymorpha

New Phytologist, EarlyView.
The gemma developmental program in Marchantia polymorpha is coordinated by MpMIR166‐mediated repression of MpC3HDZ and auxin homeostasis. Summary MicroRNAs (miRNAs) are small non‐coding RNA molecules essential for growth and development in eukaryotes. In plants, the master gene DICER‐LIKE 1 (DCL1) catalyzes the biogenesis of miRNAs by processing double‐

Mapping the Bioenergetic Landscape of Oral Cancer Stem Cells: A Systematic Review

Oral Diseases, EarlyView.
ABSTRACT Objectives Oral squamous cell carcinoma (OSSC) remains highly lethal, with resistance largely driven by cancer stem cells (CSCs). Mitochondrial reprogramming supports CSC redox control, self‐renewal, and survival. This systematic review aimed to synthesize mitochondrial mechanisms sustaining CSCs in OSCC and evaluate their therapeutic ...

Phototherapies mediated by metallic nanoparticles and near‐infrared radiation in skin cancer: A systematic review

Photochemistry and Photobiology, EarlyView.
Recent studies demonstrate that near‐infrared (NIR—750–980 nm)‐mediated photodynamic (PDT) and photothermal (PTT) therapies, combined with metallic nanoparticles (MNPs), show promising results against skin cancer, particularly melanoma, in both in vitro and in vivo models.

Radiobiology studies of gold nanoparticle‐enhanced radiosensitization in proton therapy

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Approximately 50%$\%$ of newly diagnosed cancer patients worldwide receive radiotherapy, most commonly with X‐rays. Proton therapy has emerged as a promising alternative, offering complementary advantages over conventional X‐rays due to its highly localized energy deposition at the Bragg peak, thereby reducing radiation exposure to ...

Conditioned Medium from Irradiated Keratinocytes as a Tool for Investigating Communication within the Melano‐epidermal Unit

Current Protocols, Volume 6, Issue 7, July 2026.
Abstract Keratinocytes and melanocytes form the melano‐epidermal unit, whose communication is essential for maintaining the integrity, homeostasis, and functionality of the skin. This interaction is mediated by keratinocytes’ release of various soluble factors, which modulate key processes in melanocytes such as melanogenesis, proliferation, adhesion ...
