This review discusses how Western diet may contribute to acne vulgaris through insulin signaling and metabolomic changes, promoting a dietary approach for management, but reports no new experimental results.

This study found that dermal Shh signaling regulates specific dermal papilla signatures essential for maintaining hair follicle development, suggesting that the Shh-Noggin signaling loop is crucial for hair morphogenesis.

This review discusses the roles of androgens and androgen receptors in skin-related disorders and suggests that targeting androgen receptors may be a more effective treatment strategy.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

This review summarizes recent multidisciplinary advances in sebaceous gland research and highlights potential novel therapeutic strategies for skin diseases, but it reports no new clinical results.

This review classifies mutant mice with hair abnormalities into six categories, providing an annotated table that serves as a reference for understanding the molecular controls of hair growth.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study found that deleting the miRNA processing enzymes Drosha and Dicer from mouse skin epithelial cells disrupted normal hair follicle development and maintenance, leading to follicular degradation and stem cell loss during the growth phase.

This study found that silencing clock genes BMAL1 or PER1 in human hair follicles increased melanin content and melanocyte activity, suggesting these genes influence pigmentation.

This review summarizes 15 years of clinical and experimental research advancements in hidradenitis suppurativa, highlighting its recognition as a uniquely healable inflammatory skin disease but reports no new clinical results.

This article reviews the hormonal and medication-related factors associated with acne development but does not present new research findings.

This study found that mice with a specific loss of DNA methyltransferase 1 showed uneven epidermal thickness, reduced hair regeneration, and progressive alopecia, emphasizing DNA methylation's role in stem cell homeostasis.

This review discusses the chronic nature of acne and its association with various systemic diseases, but reports no new clinical findings, highlighting the need for further study on its nutritional or genetic links.

This review summarizes existing knowledge on the role of FOXN1 as a key regulator of thymic epithelial cell lineage and function, reporting no new experimental results.

The study reports that Fgf18 and Tgf-β2 signaling pathways in hair follicle stem cells have opposing effects on the timing of hair cycle transitions, influencing the shift from telogen to anagen phases.

Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.

This study found that the transcription factors Msx2 and Foxn1 are crucial for maintaining Notch1 expression in the hair follicle matrix, which is necessary for proper hair differentiation.

In this study, topical application of fibroblast growth factors was found to promote hair growth by inducing and prolonging the anagen phase in telogenic C57BL/6 mice, suggesting potential as hair growth-promoting agents.

This review discusses recent findings on hair follicle morphogenesis and regeneration, focusing on molecular signals and stem cells, and suggests that understanding these processes may aid in developing new strategies for wound healing.

This study demonstrates that canonical Wnt signaling is crucial for maintaining thymic epithelial microenvironments in postnatal thymus, possibly by affecting TEC progenitor cells.

This study found that mice lacking the Vitamin D receptor showed disrupted hair follicle cycling, which was partially restored with hedgehog signaling pathway activation, suggesting a role for this pathway in follicle regulation independent of vitamin D.

This review presents updated tables of mouse mutants with hair growth abnormalities to aid in understanding the molecular mechanisms of human hair disorders, but reports no new clinical results.

This study analyzed skin from 538 knockout mouse mutants and identified 50 with epidermal phenotypes, providing valuable insights into genetic conditions and systemic effects related to skin abnormalities.

This review examines the role of retinoic acid synthesis in hair follicles and sebaceous glands, focusing on its localization and function during normal and disease states, but reports no new results.

This study suggests that Botox injections may increase hair count and reduce hair loss in men with androgenetic alopecia, potentially through increased blood flow and oxygen to the scalp.
