This study found that elevated androgens in the brains of glioblastoma patients are produced by tumor cells, and overexpressing Sirt1 reduces these levels, thereby delaying tumor progression more effectively than conventional therapy in mouse models.

This review details the expression and diverse functions of melatonin receptors in non-neural tissues and reports no new clinical findings, emphasizing their potential as therapeutic targets across various physiological and pathological processes.

This chapter discusses the structure and function of the skin, detailing its protective roles and the layers that comprise it, but reports no new research findings.

In this study, researchers found that disrupting the PRL gene in mice led to earlier hair molting, especially in females, suggesting that PRL inhibits murine hair cycle events.

This study found that human follicular papilla cells in the scalp produce leptin and express functional leptin receptors, suggesting leptin's significant role in hair biology.

This study found that disrupting the PRL gene in mice alters the timing of hair cycling events, causing earlier molts and changes in hair characteristics, particularly affecting female mice more significantly.

This study found that intrinsic feedback loops are crucial for maintaining the function of human dermal papilla cells during hair growth, highlighting the importance of autocrine signaling and niche reprogramming for advancing hair follicle biology and regenerative therapies for hair loss.

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.

The study found that prolactin expressed in human scalp hair follicles acts as an autocrine modulator, inhibiting hair growth and promoting hair follicle regression, which may contribute to hair loss in hyper-prolactinemia patients.

This study suggests that TGF-alpha may function in an autocrine or juxtacrine manner rather than promoting cell proliferation during hair growth cycles in ferrets and sheep.

This article reviews the various functions of the skin, its structure, and the impact that damage or disorders can have on both skin function and interpersonal communication, without presenting new experimental findings.

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 investigated the interdigital glands of moose, detailing their unique green hair coloration and the function of sebaceous and sweat glands, particularly during the rut period.

This review summarizes existing literature on PDGF's role in adipose-derived stem cells, highlighting PDGFRβ's functions in inhibiting white adipocyte differentiation and promoting proliferation and angiogenesis.

This review highlights that vitamin D is increasingly recognized for its roles in skin health, including treatment of psoriasis, potential applications in conditions like atopic dermatitis, and possible prevention of skin malignancies, as observed in various studies linking low levels to autoimmune skin diseases.

This article reviews the role of VEGF in hair follicle growth and cycle modulation but concludes that its specific molecular mechanisms in hair follicle growth remain unclear.

This article discusses the potential of using human hair follicles as a model to study prolactin's regulation and activities but reports no new experimental findings; the authors suggest further research in this area.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

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 article explains the structure and multifunctional roles of the human skin, including its protective, regulatory, and sensory functions, but does not report new research findings.

This narrative review discusses the structure and functions of the skin, focusing on its barrier role, self-repair, thermoregulation, and immune functions, and reports no new experimental results.

The skin protects the body, regulates temperature, senses touch, and makes vitamin D.

In this study, the combination of exercise and finasteride improved ovarian morphology and hormone levels in rats with polycystic ovary syndrome more effectively than either treatment alone.

This review discusses the potential link between long-term transdermal exposure to sex hormones from antiperspirants and increased breast and prostate cancer rates, calling for further research to confirm this theory.

This study reports the effective use of botulinum toxin A in treating multiple facial apocrine hidrocystomas in a 29-year-old man, a case not previously documented in English-language literature.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

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 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 study found that gonadal dysfunction is very common in premenopausal women with acromegaly and may be caused by hyperprolactinemia, GH/IGF-I excess, or tumor effects.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.
