    Abstract

    ROS Induction Targets Persister Cancer Cells with Low Metabolic Activity in NRAS-Mutated Melanoma

    The authors used multiomics analyses to reveal that NRAS-mutated melanoma cells adopt a mesenchymal phenotype with a quiescent metabolic program to resist cellular stress induced by MEK inhibition.

    Abstract

    Discovery of Clinically Used Octenidine as NRAS Repressor That Effectively Inhibits NRAS-Mutant Melanoma

    Investigators developed a novel cell-based method for large-scale screening of NRAS G4 ligand using the G-quadruplex-triggered fluorogenic hybridization probe and successfully identified the clinically used agent Octenidine as a potent NRAS repressor.

    AbstractGraphical Abstract

    Serine and One-Carbon Metabolism Sustain Non-Melanoma Skin Cancer Progression

    Expression and protein analysis of normal skin and non-melanoma skin cancer samples showed the alteration of the expression of two enzymes involved in the serine metabolism and one-carbon metabolism.

    Narrative Review of the Pathogenesis of Stasis Dermatitis: An Inflammatory Skin Manifestation of Venous Hypertension

    Because inflammation is a key driver of the signs and symptoms of stasis dermatitis (SD), several of the highlighted biomarkers of inflammation represent potential opportunities to target and interrupt molecular pathways of cutaneous inflammation and, therefore, remediate the signs and symptoms of SD.
