    Abstract

    Discrimination of Hand-Foot Skin Reaction Caused by Tyrosine Kinase Inhibitors Based on Direct Keratinocyte Toxicity and Vascular Endothelial Growth Factor Receptor-2 Inhibition

    The authors explained the incidence of hand-foot skin reaction in patients treated with tyrosine kinase inhibitors by focusing on keratinocyte toxicity and inhibition of vascular endothelial growth factor receptor, which played an essential role in angiogenesis.

    AbstractGraphical Abstract

    Trehangelins Ameliorate Inflammation-Induced Skin Senescence by Suppressing the Epidermal YAP-CCN1 Axis

    Researchers described a possible mechanism involved in skin aging focusing on the effect of trehangelins on epidermal cellular communication metwork factor 1 (CCN1).

    Regeneration of Collagen Fibrils at the Papillary Dermis by Reconstructing Basement Membrane at the Dermal–Epidermal Junction

    Investigators suggested that reconstructing the basement membrane promoted the secretion of platelet-derived growth factor consisting of two B subunits by epidermal keratinocytes, leading to increased collagen expression at the papillary dermis.

    Reduced Expression of Collagen 17A1 in Naturally Aged, Photoaged, and UV-Irradiated Human Skin In Vivo: Potential Links to Epidermal Aging

    Scientists found that matrix metalloproteinases were responsible for ultraviolet (UV)-mediated collagen 17A degradation in both in vitro keratinocytes and in vivo mouse skin.

    Abstract

    KLHL24-Mediated Hair Follicle Stem Cells Structural Disruption Causes Alopecia

    Investigators demonstrated that Kelch-like protein 24 (KLHL24) played a role in hair maintenance by regulating the cytoskeleton structure of hair follicle stem cells (HFSCs) and highlighted the importance of the ubiquitin-proteasome system in the stability of HFSCs.

    TSLP Impairs Epidermal Barrier Integrity by Stimulating the Formation of Nuclear IL-33/Phosphorylated STAT3 Complex in Human Keratinocytes

    Researchers stimulated post-confluent human keratinocytes and living skin equivalent with TSLP to investigate the role of nuclear IL-33 in TSLP-induced epidermal barrier defects.

    AbstractGraphical Abstract

    Decursin Prevents Melanogenesis by Suppressing MITF Expression through the Regulation of PKA/CREB, MAPKs, and PI3K/Akt/GSK-3β Cascades

    Decursin exhibited no cytotoxicity and significantly reduced intracellular tyrosinase activity and melanin content in B16F10 melanoma cells.
