This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This review evaluates existing research on Keratin 15 to assess its validity as a marker for epidermal stem cells, reporting no new results.

This study found that activin affects both stromal cells and keratinocytes in skin morphogenesis and repair, with dose-dependent effects on keratinocytes demonstrated through transgenic mouse models.

This study found that human skin expresses proenkephalin, whose expression is upregulated by environmental stress and varies in pathological conditions, increasing in psoriasis and decreasing in melanocytic tumors.

This study found that dysregulation of the folliculin-p0071 interaction may lead to changes in cell adhesion and signaling, contributing to conditions like emphysema and renal cell carcinoma.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study found that ectopic expression of Whn in transgenic mice caused impaired differentiation in epidermis and hair follicles, with hair growth defects and severe urinary tract issues leading to hydronephrosis.

This paper discusses the hypothesis that anti-acne agents may work by reducing FGFR2 signaling, and emphasizes FGFR2's potential role in acne pathogenesis, but it reports no new experimental findings.

This case study reported a 23-year-old woman with chronic myeloid leukemia who developed permanent hair loss after chemotherapy and did not respond to topical minoxidil treatment.

This study found that daily consumption of soft drinks significantly increases the risk of moderate-to-severe acne in adolescents, particularly if sugar intake from these drinks exceeds 100 grams per day.

This study suggests that melatonin may have a radioprotective role against X-ray-induced skin damage in rats, as evidenced by milder injury markers in pretreated animals.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study found that disrupting Smad4 signaling in young mice led to overactivation of follicle stem cells, causing hyperplasia and depletion of the stem cell niche.

This study found that procyanidin B-2 may promote hair growth by reducing expression and inhibiting translocation of PKC isozymes in murine hair epithelial cells.

In this study, proliferative and necrotizing feline otitis externa in four domestic shorthair cats improved with topical 0.1% tacrolimus treatment, despite previous ineffective therapies.

This review discusses the potential roles of calcium in the regulation of pluripotent and tissue-specific stem cells but reports no new experimental results, highlighting areas for future research.

This study found that using ectopic expression of CD24 is a promising approach for selecting genetically modified human epidermal stem cells for safe cutaneous gene therapy in cancer-prone conditions.

This review discusses the epidemiology, clinical manifestations, and pathogenesis of autoimmune skin diseases and their associations with thyroid diseases, reporting no new clinical results.

This review discusses recent advances in the genetic understanding of inherited hair and nail disorders and reports no new clinical results.

This study documented the progression of exfoliative cutaneous lupus erythematosus in German shorthaired pointers and found generally poor responses to therapies, including immunomodulatory drugs and a TNF-α inhibitor.

This study found that acne inversa is primarily an epithelial-driven disease, with cyst-forming tendrils causing inflammation due to rupture and the release of debris, highlighting limitations of punch biopsies for analysis.

This review discusses the relationship between zinc deficiency and skin disorders, emphasizing zinc transporters' roles, but it reports no new clinical results; the authors highlight potential benefits of regulating zinc levels via transporters.

This study found that keratoacanthoma of the lip likely arises from outer root sheath cells, based on the presence of specific keratin markers and periodic acid-Schiff staining patterns.

In this study, symmetrical acrokeratoderma was observed to frequently occur alongside ichthyosis vulgaris, with no specific therapy available for the condition.

This review assessed the potential of mesenchymal stem cell therapy to enhance burn wound healing, highlighting its capabilities in promoting angiogenesis, reducing inflammation, and regenerating damaged tissues, while identifying preclinical and clinical challenges that need addressing to optimize treatment outcomes.

In this study, researchers identified a new dominant mutation in Hairless mice, called Pied, resulting from a deletion in the Adam10 gene, which causes freckle-like skin pigmentation by inhibiting melanocyte expansion.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

This review discusses updates in the genetics and clinical understanding of congenital ichthyosis and highlights the addition of N-acetylcysteine and topical enzyme replacement to the treatment options, without providing new clinical results.

This review explores the potential use of plucked hair follicles in regenerative medicine and diagnostics but presents no new research findings.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.
