In this study, α-MSH and cyclic AMP were found to stimulate melanogenesis in hair follicle cultures, while cyclic GMP and melatonin inhibited melanin production but not tyrosinase activity.

This study presents a method for extracting and measuring cyclic AMP in small amounts of skin tissue, finding varying levels in the dermis, epidermis, and hair follicles.

In this study, the pharmacological action of dobutamine on rabbit retinae was found to be distinct from that of other dopamine analogs like apomorphine and N-methyl-dopamine.

Interleukin-1β stops hair growth by increasing cyclic AMP levels.

Melatonin stops melanin production after tyrosinase action, with cyclic GMP mimicking this effect.

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.

Diazoxide, minoxidil sulphate, and cromakalim relax rat blood vessels by opening K+ channels, with some differences in their actions.

This study found that 17β-estradiol inhibited RANTES production in human keratinocytes by suppressing nuclear factor κB activity, suggesting a potential mechanism for 17β-estradiol's modulation of psoriasis-related inflammation.

Human hair follicles have a unique metabolism that changes between growth stages and may contribute to baldness.

This review discusses the uncommon but potentially serious cutaneous reactions to beta-adrenergic blockers and the uncertain pathogenesis, with no new clinical results reported.

In this study, 17β-estradiol increased VEGF production in differentiated THP-1 cells, while dihydrotestosterone counteracted this effect by modulating adenylate cyclase activity.

This study found that the L457(3.43)R mutation in the human luteinizing hormone receptor increases phosphodiesterase activity, reducing hormonal response despite elevated basal cAMP levels.

This review discusses the evolution of scientific understanding and treatment approaches for androgenetic alopecia, from androgen metabolism to the potential of biologic response modifiers, reporting no new clinical findings.

This study demonstrated that α-phellandrene promotes dermal papilla cell proliferation through a cAMP-mediated pathway and upregulates VEGF expression, suggesting its potential use in hair loss prevention.

Coffee and tea might help hair growth in balding individuals, but side effects and alternative uses are being considered.

This article reviews the types and characteristics of adrenal cortex tumors, including their hormone secretion and detection as incidental findings, but presents no new research results.

Caffeine in Alpecin shampoo may help prolong hair root activity and reduce hair loss.

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 narrative review discusses the hormonal control of hair growth, particularly focusing on dihydrotestosterone and its role in the pilosebaceous unit and androgen-related hair conditions, and does not report new findings.

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 study found that altering CDK4 expression in mice affects the population of keratinocyte stem cells, suggesting a correlation with susceptibility to skin papillomas.

This review examines the antitumor effects of metformin and highlights discrepancies between basic and clinical study results, noting that these may be due to different dosing levels.

This abstract does not provide specific findings or results.

This study explored the structure and function of lipocalin prostaglandin D synthase, revealing its dual role in substrate catalysis and as a lipophilic ligand carrier, potentially informing future drug delivery design.

This study found that AtT-20 pituitary cells with higher cAMP-dependent kinase activity had larger calcium currents and significantly increased beta-endorphin release compared to cells with lower kinase activity.

This case report highlights a successful treatment with granulocyte colony-stimulating factor for cyclic neutropenia in a 16-year-old girl experiencing recurring oral aphthae and fever.

This review discusses the emerging roles of transit-amplifying cells in tissue regeneration and cancer formation, highlighting their significance beyond a mere transitional state in hair follicles and the hematopoietic system.

This study observed that human hair follicles with a completely destroyed bulb can regenerate after being grafted onto immunodeficient mice, entering a shortened dystrophic telogen followed by anagen phase.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This study found that overexpression of sPLA2-IIA in homozygous mice resulted in cyclic alopecia, a halt in hair follicle cycling, and impaired wound healing due to complete loss of hair follicle stem cells.
