This study found that super-enhancers are essential for hair follicle stem cell identity, lineage commitment, and plasticity in mice, with SOX9 being a key regulator of these chromatin dynamics.

This study found that the cytokeratin patterns in skin epithelia can distinguish between different types, with basal-cell epitheliomas showing a striking similarity to the pilosebaceous tract.

This study found that Wnt signaling in the hair follicle is crucial for coordinating the behavior of epithelial and melanocyte stem cells, which drives hair regeneration and melanocyte differentiation in mice.

This review discusses the identification and characteristics of melanocyte stem cells, emphasizing their role in hair pigmentation, greying, and skin repigmentation, but reports no new research findings.

Hair growth and pigmentation in mice involve specific stages crucial for research.

This study observed that serum levels of oestradiol, testosterone, and androstenedione increase rapidly with the onset of puberty and continue to rise after menarche, with anovulatory cycles being common in early postmenarchal girls.

This review discusses the development, regulation, and aging of the human hair follicle pigmentary system and suggests potential for reversing hair graying by manipulating follicle melanocytes in vitro, but reports no clinical results.

This study found that trilostane was effective in resolving symptoms such as polyuria and polydipsia in many dogs with pituitary-dependent hyperadrenocorticism, with significant hormone level reductions observed.

This article discusses mouse genetic studies to explore factors influencing melanogenesis, highlighting pH and cysteine's roles, and proposes a hypothesis for human hair color diversity; it reports no new results.

This study found that estrogen receptor beta, not alpha, is the main mediator of estrogen action in human skin and hair follicles, suggesting a distinct role in these tissues.

This article discusses the challenges in hair follicle pigmentation research compared to epidermal melanocytes and highlights the limitations of relying on mouse models, but reports no new experimental findings.

This study found that expressing certain PIN proteins in Arabidopsis root hairs inhibited growth by decreasing auxin levels, while PIN5 slightly stimulated growth, demonstrating differential effects on auxin transport.

This study found trilostane to be an effective and generally safe treatment for improving symptoms in dogs with pituitary-dependent hyperadrenocorticism.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that ultrasonography improved preoperative diagnosis rates of pilomatricoma to 76% by identifying specific features such as inner echogenic foci and a peripheral hypoechoic rim.

This study found that combining near-infrared laser phototherapy with indocyanine green application may improve acne vulgaris by reducing active lesions and inflammation without side effects.

This study describes how feather pigmentation in birds is regulated by melanocyte distribution, differentiation, and patterned agouti expression, contributing to diverse and adaptive color patterns.

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

Pityriasis rubra pilaris is a rare skin disorder with reddish-orange patches and thickened skin, needing better treatment understanding.

This narrative review discusses lichen planus pigmentosus, including its variations, associated triggers, and management strategies, but reports no new clinical results.

This abstract outlines dermatological topics related to skin pathology and does not provide any new research findings.

In this study, disruptions in phospholipase A2 activity in Arabidopsis thaliana significantly impaired the plasma membrane localization of PIN proteins, affecting auxin transport and root development.

This review explores how androgens and growth hormone influence the development of terminal hairs and sebaceous glands, attributing variability in hirsutism and acne to differing genetic sensitivities to androgens, but reports no new experimental data.

This study found that the Dun camouflage color in horses is due to TBX3 expression, which causes uneven pigment deposition, whereas non-dun coat colors result from regulatory mutations affecting TBX3 expression.

Oral dutasteride and topical pimecrolimus can safely and effectively treat Frontal Fibrosing Alopecia, leading to significant hair regrowth.

In this study, status epilepticus in rats induced P450scc in hippocampal glia, which was associated with a delayed onset of spontaneous seizures, while inhibiting neurosteroid synthesis accelerated seizure onset if P450scc was significantly increased.

Small white dots on the scalp seen with a dermoscope correspond to sweat ducts and vary with different hair disorders.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

Pioglitazone may help treat lichen planopilaris, but more research is needed.

This article discusses the role of neurohormones and neuropeptides in hair follicle pigmentation and outlines promising neuroendocrinological strategies to address greying and damage, but reports no new clinical results.
