This article reviews the complex signaling pathways between epithelial and mesenchymal cells crucial for hair follicle morphogenesis, highlighting the Wnt pathway's role as a master regulator without reporting new experimental findings.

This study found that normal human melanocytes can be protected from apoptosis through both PI 3-kinase/Akt-dependent and independent pathways, with insulin and TPA offering nearly complete protection.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This review discusses the immune roles of keratinocytes in wound healing and chronic wound inflammation, emphasizing their potential impact on chronic wound pathology and highlighting areas for future research.

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 review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This study reports that adipose-derived stem cells can protect against radiation-induced dermatitis in rats by reducing apoptosis through lowering Cathepsin F expression, suggesting a potential new therapeutic approach.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

This review discusses the current understanding of androgen biosynthesis, mechanisms of action, and their roles in human biology, as well as related congenital and acquired disorders, but it reports no new research findings.

This study found that c-Jun is essential for vitamin D receptor expression, and the vitamin D receptor inhibits c-Jun-dependent cell death through non-classical mechanisms independent of vitamin D3.

This review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

This study found distinct gene expression patterns in the blood of alopecia areata patients, suggesting involvement of immune processes and new pathways like Wnt signaling and apoptosis in disease pathogenesis.

Acankoreoside J from Acanthopanax koreanum may help promote hair growth.

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

This study found that ATM protein plays a crucial role in protecting human hair follicle melanocytes from oxidative stress, which is linked to the greying of hair.

This paper reviews the role of endoplasmic reticulum stress and the unfolded protein response in Hutchinson-Gilford progeria syndrome-related atherosclerosis, especially in vascular smooth muscle cells, but reports no clinical findings; intervention in these pathways is suggested as a potential therapeutic strategy.

In this study, Epimedii Folium extract was found to enhance melanin production and promote pigmentation through mechanisms involving the MAPK/ERK1/2 pathway in both in vitro and in vivo models.

This study found that hair follicle stem cells in the hairpoor mouse, a model for Marie-Unna hypotrichosis, lose their quiescent state, leading to a disordered hair cycle and contributing to alopecia.

In this study on fine-wool sheep, researchers found that overexpressing the TGFBR1 gene decreased proliferation of dermal papilla cells by influencing multiple signaling pathways, suggesting TGFBR1 as a negative regulator in hair follicle development.

This study identified specific keratin-associated protein genes that are highly expressed in different varieties and sexes of Angora goats, providing insights for improving mohair development through targeted breeding strategies.

This study found that adenosine promotes hair growth by stimulating the Wnt/β-catenin pathway in cultured human dermal papilla cells through activation of the adenosine receptor.

This research suggests that the barley protein RACB supports cell polarity functions rather than interfering with immunity, as it aids nucleus positioning during fungal attack rather than affecting early immune responses.

This study reports that in MRL mice, loss of p53 does not impair ear regeneration, suggesting p21's potential role in this process may involve the Tgfb/Smad pathway.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

This review discusses the effects of photobiomodulation, particularly its potential to reduce inflammation in various conditions, but it does not report new clinical findings.

This study found that sorafenib was active against desmoid tumors, with 25% of patients achieving a partial response and 70% maintaining stable disease.

This study found that activation or inhibition of Wnt/β-catenin and Notch signaling pathways in rats can alter wound healing, possibly by affecting epidermal stem cell activity and keratinocyte behavior.

Caspase-3 helps control cell growth and organ size by activating YAP.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study reports that overexpressing the BMP antagonist noggin in mice inhibits eyelid opening by reducing apoptosis and delaying cell differentiation in the eyelid epithelium.
