This study identifies specific localization patterns of androgen, estrogen, and progesterone receptors in human skin, which could be crucial for understanding their roles in skin biology and pathology.

This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that the transcription factor Gata6 regulates the sebaceous duct lineage identity and plays a crucial role in epidermal wound healing by enabling dedifferentiation and broader lineage capabilities in post-mitotic cells.

This review discusses the diverse roles and characteristics of epidermal and dermal stem cells in skin regeneration and aging, highlighting their potential applications in regenerative medicine and reports no new clinical results.

This study found that absence of the vitamin D receptor in keratinocytes impairs canonical Wnt signaling and leads to alopecia due to defects in keratinocyte stem cells.

This review discusses the histopathology of male-pattern baldness and highlights ongoing disputes over several aspects, including sebaceous gland size and follicle loss, reporting no new clinical findings.

This review covers follicle-targeting drug delivery systems, exploring their potential for improving localized and systemic therapies, and highlights the need for further research into follicle penetration mechanisms.

This review examines the role of hair follicles and sebaceous glands in percutaneous drug delivery but does not report new clinical results; it calls for further exploration of follicle-targeting therapies.

This review discusses skin changes during pregnancy, highlighting both pregnancy-specific and common physiologic changes, but reports no new clinical findings.

This review explores the impact of vitamin D deficiency on the skin from a dermatological perspective, but reports no new clinical results.

This study found that Rac1 is crucial for maintaining the integrity of hair follicle structure but is not needed for skin epidermis maintenance in mice.

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 review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

This review summarizes recent research on the skin microbiome's role in acne development and how antibiotic treatments affect skin microbes, but it reports no new clinical results.

This study found that disrupting Adam10 in the epidermis led to severe skin and multi-organ abnormalities, implicating Adam10 as crucial for proper Notch signaling and skin maintenance.

Fgfr2b helps maintain healthy skin and prevent cancer.

EGF receptors are crucial for skin cell growth and decrease with age.

In this study, ethosomes were found to improve the skin penetration of a model lipophilic drug more effectively than liposomes or hydroethanolic solutions, suggesting a unique mechanism involving the breakdown of vesicles in the skin.

This study reports the successful differentiation of mouse induced pluripotent stem cells into keratinocytes that can regenerate skin and its structures in an in vivo environment.

Phospholipase Cδ1 is crucial for normal skin and hair development.

This study suggests that finasteride's effect on promoting hair growth in men with androgenetic alopecia may be due to its inhibition of 5aR2 localized in hair follicles.

This review explores the role of hormones in pilosebaceous units and associated skin disorders, focusing on androgen action, without presenting new clinical findings.

This study identified WNT10A as crucial for adult epithelial cell proliferation and differentiation, suggesting β-catenin pathway activation may help address regenerative defects in WNT10A mutation patients.

This study found that G protein-coupled estrogen receptor enhances melanin synthesis in melanoma cells through cAMP-PKA-MITF-TYR signaling, suggesting its potential as a drug target for chloasma treatment.

In this study, the researchers observed that male pattern alopecia is characterized by miniature follicles, enlarged sebaceous glands, and an increased number of mast cells, without significant abnormalities in enzyme activity.

This study demonstrates that hair follicle bulge stem cells can transition into other stem cell compartments, indicating their role in maintaining both hair follicles and sebaceous glands.

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

This review outlines the classification, histopathologic presentation, and pathogenetic concepts of scarring and nonscarring alopecias, reporting no new clinical results and emphasizing the need for clinicopathologic correlation.

This study reported that antimicrobial and topical retinoid therapies led to significant changes in the lipid profiles of sebaceous follicular infundibulum, with increased triglycerides and ceramide subfractions observed.

This study found that in hamster flank organs, 17βC inhibited enlargement caused by topical testosterone but not by DHT, suggesting potential use in androgen-related skin disorders like acne.
