Persister State-Directed Transitioning and Vulnerability in Melanoma

[Nature Communications] The authors established a doxycycline-titratable system for genetic induction of permanent intratumor expression of KDM5B and screened for chemical agents that phenocopy this effect.

Inhibition of USP14 Enhances Anti-tumor Effect in Vemurafenib-Resistant Melanoma by Regulation of Skp2

[Cell Biology and Toxicology] In vitro, the effect of the combination regimen of vemurafenib and b-AP15 on vem-sensitive and vem-resistant melanoma has been investigated by wound healing, colony formation, transwell invasion assay, flow cytometry, lysosome staining, and ROS detection.

Lattice-Patterned Collagen Fibers and Their Dynamics in Axolotl Skin Regeneration

[iScience] Researchers succeeded in visualizing collagen-producing cells and produced collagen using the axolotl skin, which is highly transparent. The visualized dermal collagen had a lattice-like structure.

The ASIC3-M-CSF-M2 Macrophage-Positive Feedback Loop Modulates Fibroblast-to-Myofibroblast Differentiation in Skin Fibrosis Pathogenesis

[Cell Death & Disease] The polarization of M2 macrophages transduced by the acid-sensing ion channel 3 (ASIC3)-macrophage colony-stimulating factor (M-CSF) signal promoted the differentiation of fibroblasts into myofibroblasts through transforming growth factor β1 (TGF-β1), thereby producing an ASIC3-M-CSF-TGF-β1 positive feedback loop.

Three-Dimensional Imaging for the Analysis of Human Epidermal Melanocytes

[Pigment Cell & Melanoma Research] The purpose of this study was to standardize 3-D imaging and quantification for the evaluation of epidermal melanocytes.

Non-Melanoma Skin Cancers: Physio-Pathology and Role of Lipid Delivery Systems in New Chemotherapeutic Treatments

[Neoplasia] The characteristics of non-melanoma carcinoma is discussed, describing the main existing treatments, together with the contribution of lipid delivery systems as an innovative approach to increase the effectiveness of topical therapies for non-melanoma carcinomas.

Proximity between LAG-3 and the T Cell Receptor Guides Suppression of T Cell Activation and Autoimmunity

[Cell] To exploit LAG-3’s proximity to T cell receptor (TCR) and maximize LAG-3-dependent T cell suppression, scientists developed an Fc-attenuated LAG-3/TCR inhibitory bispecific antibody to bypass the requirement of cognate peptide-MHC class II.

Chemosensor Receptors Are Lipid-Detecting Regulators of Macrophage Function in Cancer

[Nature Immunology] Researchers conducted an unbiased genome-wide CRISPR screen of primary macrophages. Their study confirmed the function of known regulators in tumor associated macrophage responses and revealed new insights into the behavior of these cells.

A Genome-Wide Association Study Integrated With Single-Cell and Bulk Profiles Uncovers Susceptibility Genes for Nasopharyngeal Carcinoma Involved in Tumorigenesis Via Regulation of T Cells

[Genome Biology] Scientists performed in-depth bioinformatic analysis and functional experiments for EOMES, finding that the nasopharyngeal carcinoma-risk alleles of four functional SNPs upregulate EOMES expression by promoting the activity of regulatory elements in T cells.
