This study found that mutant Cx43 impairs fibroblast function during wound healing and reduces hair follicle cell proliferation, likely contributing to hair growth defects in ODDD patients.

This study demonstrated that tight junction barriers exist in human hair follicles but are less tight in hair follicle keratinocytes than in interfollicular keratinocytes, highlighting claudin-1's key role in follicle barrier function and growth.

This review outlines the structure and functions of the skin, emphasizing its role as a physical and immune barrier, its moisture regulation, the influence of its microbiome, and the supportive functions of its layers and adnexa.

This chapter examines how toxins such as inorganic arsenic, dioxin, and bacterial toxins can disrupt the balance of keratinocyte stem cell regeneration and differentiation, affecting skin barrier maintenance.

This study suggests that decreased PPARgamma function may trigger the pathogenesis of lichen planopilaris, and PPARgamma-targeted therapy could be a potential treatment method.

Increasing m6A levels can improve skin cell growth and wound healing.

This review discusses the molecular and functional aspects of the nude gene in skin biology, providing insights into its role and evolutionary development, but reports no new results.

This study found that loliolide enhanced hair growth-related functions in 3D dermal papilla spheroids by activating AKT/β-catenin signaling pathways, with increased expression of related growth factors and genes.

This study identified mutations in the SREBF1 gene that impair SREBP1 function, potentially contributing to IFAP syndrome by affecting skin, hair, and eye development.

This review discusses the role of microRNAs in skin function and potential therapeutic applications, emphasizing their importance in wound healing and disease management, though it reports no new experimental findings.

This study found that acid and alkaline phosphatases serve different functions in Beagle dog skin, with ALP primarily involved in growth processes and ACP in phospholipid breakdown.

This study examines various growth factors' roles in hair cell function and suggests insulin-like growth factor may stimulate hair growth, while the precise mechanism of growth inhibition remains unclear.

This study found that thyroid-stimulating hormone receptors are functionally expressed in various skin cells, implying potential physiological and pathological roles in skin, especially in conditions like autoimmune diseases.

This review examines how vitamin D and its receptor regulate various skin functions, such as cell differentiation and immunity, and explores the mechanisms involved, without reporting new clinical results.

This study found that RXRα plays a critical role in hair cycling and keratinocyte functions in mice, likely through its interaction with VDR in epidermal cells.

In this study, the researchers found that alopecia in VDR null mice is likely due to issues with hair cycle initiation rather than defects in keratinocyte proliferation or differentiation.

This study suggests that alopecia in vitamin D receptor null mice is due to impaired initiation of the hair cycle rather than defects in keratinocyte proliferation or differentiation.

This review discusses current knowledge about the TRPV3 ion channel's role in skin functions and diseases, highlighting its potential as a therapeutic target for pain and itch, though suitable ligands are limited.

This review discusses the roles of store-operated Ca 2+ entry proteins in skin cell function and their links to various skin diseases, but it reports no new results.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This review discusses recent advances in how proinflammatory cytokines affect epidermal stem cell function during skin wound healing and introduces potential therapies targeting these cells and cytokines.

This review discusses the role of the Slug transcription factor in various epidermal functions and its distinction from the related Snail factor, without presenting new research findings.

This review examines the role of vitamin D and its receptor in skin functions, exploring mechanisms regulating proliferation, differentiation, immunity, and tumor suppression, without reporting new research findings.

In this study, researchers observed that the absence of a functional vitamin D receptor in mice leads to impaired hair follicle regeneration due to defects in keratinocyte stem cells, resulting in alopecia.

This study found that bikunin is expressed in human keratinocytes and may play a role in regulating keratinocyte function during mitosis or inflammation.

This study found that in squamous cell carcinomas, the inhibition of the tumor-suppressor function of TAp73β by ΔNp63α occurs through promoter squelching, not direct protein interaction.

This study found that arachidonic acid may promote hair growth by enhancing dermal papilla cell function and stimulating the anagen phase in C57BL/6 mice.

This study found that the SVpgC2a keratinocyte cell line, used as a model for dysplastic epithelium, showed increased apoptosis, proliferation, and aberrant keratin expression compared to normal keratinocytes from buccal mucosa.

This study found that erythropoietin promotes hair growth by stimulating dermal papilla cells with functional erythropoietin receptors, enhancing hair shaft elongation and anagen phase in cultured human hair follicles and in mice.

This study highlights emerging research on lactate's biological roles in skin health, emphasizing its function as a signaling molecule that regulates skin barrier and immunity, and notes its therapeutic potential for skin conditions such as tumors and inflammatory diseases.
