This case study of a cat with pancreatic carcinoma and paraneoplastic alopecia found that removing the internal tumor reversed hair loss, but symptoms reappeared as the cancer metastasized.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This study demonstrated that cultured human dermal papilla cells can induce full hair follicle formation when combined with neonatal foreskin keratinocytes in a grafted dermal-epidermal construct on mice.

This review discusses prolactin production and regulation in human skin and hair follicles, highlighting its potential broader implications but reports no new empirical results.

This study concluded that an endogenous circannual rhythm of prolactin secretion in mouflon influences their seasonal hair growth and moulting cycle, which varies under different photoperiodic and melatonin treatments.

Finasteride increases hair density in female androgenetic alopecia, but individual results may vary.

This review discusses the role of estrogens in hair follicle cycling and the skin, highlighting the need for more research on estrogen signaling pathways and their interactions with other factors in hair biology.

This study found that only eumenorrheic polycystic ovary syndrome patients showed a temporal coupling between kisspeptin and luteinizing hormone pulsatile secretions.

In this study, red ginseng extract and its ginsenosides enhanced human hair follicle cell proliferation and countered dihydrotestosterone-induced suppression, suggesting potential to promote hair growth.

This review explores the complex relationship between thyroid hormones and skin, discussing potential mechanisms and known interactions but reports no new clinical results, emphasizing the need for further research.

In a study on muscle regeneration in mice, researchers found that platelet-secreted CXCL7 is crucial for recruiting neutrophils to injury sites, aiding early muscle repair and optimal regrowth, suggesting potential therapeutic uses for boosting muscle healing.

This study found that stem cells derived from spinal and bulbar muscular atrophy patients exhibited reduced androgen receptor levels and HDAC6, providing potential insights into the disease mechanism for future therapies.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

This letter discusses the potential connection between androgenetic alopecia and COVID-19, suggesting a possible new therapy, but it reports no new results.

This review discusses the steroidogenic properties of human skin and suggests that impaired steroidogenesis may be linked to conditions like acne, rosacea, atopic dermatitis, and androgenic alopecia, but reports no new clinical results.

This study found that overexpressing human Bcl-2 in mice protected epidermal keratinocytes from UVB-induced apoptosis but unexpectedly increased apoptosis during hair follicle regression and chemotherapy.

This study identified thyrotropin-releasing hormone (TRH) as a stimulant of wound healing in both frog and human skin models, suggesting it as a potential neuroendocrine wound repair promoter.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This study found that Florida manatees have unique types of specialized nerve endings in their vibrissae, which assist in their sensory and manipulative functions in aquatic environments.

This review discusses the broadening scope of botulinum toxin applications beyond traditional uses, highlighting its effects on non-neuronal cells and potential in treating various dermatological conditions, without reporting new clinical findings.

This study observed that epidermal growth factor and fibroblast growth factor have distinct roles in sheep skin, with EGF involved in differentiation and FGF in bulb proliferation and fiber growth.

This review explores the relationship between hair follicles and wound healing, emphasizing the importance of translating scientific findings into practical therapies for chronic wounds, but it reports no new experimental results.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This study observed that nuclear β-catenin expression in non-small-cell lung carcinomas correlates with increased proliferation and loss of key cell-cycle checkpoints, suggesting an oncogenic advantage.

This review discusses the challenges and potential solutions in studying Demodex mites and their possible pathogenic role in human skin disorders but reports no new findings.

This study found that leptin acts as an inducer of the anagen phase in hair follicles, suggesting its role as a potential player in hair biology.

This article reviews the potential role of prolactin as a neuroendocrine modulator in skin biology and pathology, discussing its relevance for conditions such as psoriasis and hair growth, but reports no new clinical findings.

This review discusses post-SSRI sexual dysfunction and post-finasteride syndrome, highlighting unknowns about their true incidence and underlying causes, and reports no new clinical results.

This study found that combining platelet-rich plasma with adipose-derived mesenchymal stem cells significantly improved diabetic wound healing in rats by enhancing angiogenesis and modulating the Notch signaling pathway.

This study observed that autologous bone marrow derived mononuclear cells and follicular stem cells were both safe and effective for improving resistant alopecia areata and androgenetic alopecia, with no serious adverse events.
