    The HPV8 E6 Protein Targets the Hippo and Wnt Signaling Pathways as Part of Its Arsenal to Restrain Keratinocyte Differentiation

    Investigators reported that the human papillomavirus type 8 (HPV8) E6 protein could subvert Hippo signaling by activating Transcriptional Enhanced Associate Domain transcriptional programs that inhibited the expression of keratinocyte differentiation markers.

    Scalp Bacterial Species Influence SIRT1 and TERT Expression in Keratinocytes

    To evaluate scalp bacteria’s effect on human keratinocyte cellular activity, including that of the hair follicular keratinocytes, the expression of several longevity genes was examined using HaCaT cells.

    IL-6 Trans-Signaling in a Humanized Mouse Model of Scleroderma

    Investigators tested whether the MISTRG6 strain of humanized mice could be transplanted with healthy or scleroderma human skin grafts. They found that healthy and scleroderma skin grafts retained skin and bone marrow–derived immune cells.

    GREB1 Isoform 4 Is Specifically Transcribed by MITF and Required for Melanoma Proliferation

    Researchers showed that the expression of the growth regulation by estrogen in breast cancer 1 (GREB1) splicing variant, isoform 4, was mediated by microphthalmia-associated transcription factor (MITF) in melanoma cells.

    Inhibitory Effect of Sanguisorba hakusanensis Makino Ethanol Extract on Atopic Dermatitis-Like Responses in NC/Nga Mice and Human Keratinocytes

    Scientists investigated anti-atopic and anti-inflammatory activities of Sanguisorba hakusanensis ethanol extract both in vivo using NC/Nga mice and in vitro using human HaCaT keratinocytes.

    An In Vitro Investigation of L-Kynurenine, Quinolinic Acid, and Kynurenic Acid on B16 F10 Melanoma Cell Cytotoxicity and Morphology

    Researchers investigated the effects of exogenous kynurenine compounds on melanoma cells in vitro. They found that the various exogenous kynurenine compounds each displayed different levels of cytotoxicity, which were cell-line specific.
