research The Phenotypic and Genotypic Spectra of Ichthyosis With Confetti Plus Novel Genetic Variation in the 3′ End of KRT10
Ichthyosis with confetti is a genetic skin disorder with consistent ectodermal malformations and various KRT10 gene mutations.
research Building Models for Keratin Disorders
Krt16-deficient mice help understand skin disorders like PC and FNEPPK.
research Reversible Activation of c-Myc in Skin
The study investigated the effects of activating the protooncogene c-Myc in adult skin epidermis. Researchers used a switchable form of c-Myc protein, c-MycER, to target the suprabasal epidermis. Activation of c-MycER led to rapid proliferation and disrupted differentiation of keratinocytes, resulting in papillomatosis and angiogenesis, which are similar to hyperplastic actinic keratosis, a precancerous condition. Importantly, these premalignant changes regressed spontaneously when c-MycER was deactivated, indicating that the effects were reversible.
research The Effect of Finasteride on the Expression of Vascular Endothelial Growth Factor and Microvessel Density: A Possible Mechanism for Decreased Prostatic Bleeding in Treated Patients
Finasteride may reduce prostate bleeding by lowering blood vessel growth factor levels and blood vessel density in certain prostate areas.
research Ornithine decarboxylase expression in cutaneous papillomas in SENCAR mice is associated with altered expression of keratins 1 and 10.
The study investigated the expression patterns of ornithine decarboxylase (ODC) and keratins in early papillomas in SENCAR mice to identify markers for early skin tumorigenesis. Tumors were induced using 7,12-dimethylbenzanthracene and promoted with 12-O-tetradecanoylphorbol-13-acetate. In early papillomas, keratin K1 showed patchy staining, while K10 was minimally expressed, contrasting with their normal expression in mildly hyperplastic epidermis. ODC expression was intense and diffuse in suprabasal cells of papillomas, correlating with decreased K1 and K10 expression, indicating altered differentiation. These findings suggested that high ODC expression and reduced K1 and K10 could serve as markers for early tumorigenesis in mouse skin.
research Gomez–Lopez-Hernandez Syndrome: Two New Cases and Review of the Literature
The document adds two cases of Gomez-Lopez-Hernandez syndrome and suggests including trigeminal anesthesia and scalp alopecia as key diagnostic criteria.

Aging reduces stem cell activation, leading to hair loss in mice lacking a specific enzyme.
research Epidermal cell proliferation and modulation of the protective potency of dexamethasone against phorbol ester-induced ornithine decarboxylase activity
The study investigated the effects of dexamethasone (DXME) on mouse skin treated with 12-O-tetradecanoyl-phorbol-13-acetate (TPA). DXME, when applied after TPA, inhibited both the dermal inflammatory reaction and the induction of epidermal ornithine decarboxylase (ODC) activity. During the hyperplastic stage, DXME continued to counteract inflammation but only weakly inhibited ODC induction. Interestingly, in DXME-protected skin, the hyperplastic stage was delayed, and TPA strongly induced ODC activity in the epidermal cell layer before this stage. The study suggested that as the proliferation process was induced, epidermal cells became more sensitive to TPA, potentially becoming less reliant on inflammatory factors for ODC induction.
