In this study, researchers found that the thyroxine receptor agonist TDM10842 accelerated the onset of anagen, a hair growth phase, in C3H mice, potentially through activation of the Wnt/beta-catenin and Hedgehog pathways, with Pclaf playing a key role in this process.

This review highlights the critical role of microRNAs in regulating hair follicle biology, significantly impacting wool and cashmere development by modulating gene expression and signaling pathways in sheep and goats.

This study found that, despite confirming MC1R expression and functional cAMP signalling, α-MSH treatment did not alleviate UVA-induced stress in adult dermal fibroblasts, suggesting that α-MSH-MC1R may not directly protect against UVA-induced photoaging in these cells.

This case study reported a unique instance of a benign adrenal adenoma co-secreting cortisol and DHEA-S, which initially mimicked PCOS symptoms. Surgical removal resulted in significant clinical improvement, confirming the diagnosis of cyclic adrenal Cushing's syndrome.

This review highlights the hair follicle's structural and functional properties as an effective route for delivering active compounds in treating hair disorders, focusing on emerging carrier technologies to enhance targeted transfollicular delivery.

This study discovered that calcium dependent protein kinase 1 (CPK1) directly activates cyclic nucleotide-gated channels 5, 6, and 9, promoting root hair growth in Arabidopsis by regulating Ca²⁺ signaling.

In this study, researchers observed that mutant mice with a genetic hair loss condition exhibited significant differential expression of genes related to keratinization and hair follicle formation, providing insights into potential strategies for understanding and treating alopecia.

In this study, researchers observed that spontaneously mutated mice with a hair loss phenotype exhibited significant differential expression of genes related to keratinization and hair follicle formation, suggesting these mice could model human alopecia for future research and treatment development.

This study found that tribuloside, a flavonoid from Tribulus terrestris L., enhances melanin production in human melanocytes, zebrafish, and human skin samples without causing toxicity, potentially through inhibiting PDE to increase cAMP levels and promote the melanin biosynthesis pathway.

In this study, researchers analyzed the skin proteome of Alpine Merino sheep to identify proteins and pathways related to wool fiber diameter, finding that cyclic adenosine monophosphate and certain signaling pathways may play a role in this trait.

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

This study achieved regeneration of hair follicle-like structures and erector muscle of hair in vitro by simulating cellular organization and applying mechanical stimuli.

This study developed in vitro methods to regenerate hair follicles and erector muscles by mimicking their native structures and mechanical conditions, reconstructing hair follicle-like structures and forming muscle-like tissues.

Vitamin D receptor is crucial for hair growth, not vitamin D itself.

This review examines the effectiveness of current treatments for androgenetic alopecia, offering plastic surgeons evidence-based guidance for choosing safe and effective options, but reports no new results.

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.

In this study, a two-year-old black Dobermann pinscher with progressive dorsal hair loss and folliculitis showed a partial response to prolonged omega-3/omega-6 fatty acid treatment.

In this study on fine-wool sheep, researchers found that overexpressing the TGFBR1 gene decreased proliferation of dermal papilla cells by influencing multiple signaling pathways, suggesting TGFBR1 as a negative regulator in hair follicle development.

This laboratory study found that dendrobium officinale polysaccharide (DOP) stimulated hair follicle and hair growth in mice by activating the WNT signaling pathway.

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.

In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.

This study found that loss of Ptch1 function in mouse skin's basal cells is sufficient to rapidly induce tumors resembling human basal cell carcinoma, suggesting Ptch1 as a key tumor suppressor.

This study found that transgenic mice overexpressing E2F1 in their epidermis developed skin tumors, confirming in vivo that deregulated E2F1 activity can contribute to tumor development.

This study found that deleting β-catenin in epidermis-specific VDR knockout mice did not prevent UVB-induced skin tumors, indicating β-catenin does not compensate for VDR's role in tumor suppression.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This study reported that exposure to 1,763 MHz radiofrequency radiation stimulated hair growth in vitro by inducing insulin-like growth factor-1 expression in cultured human dermal papilla cells.

This study reported that tryptanthrin, a compound found in indigo naturalis, effectively suppresses non-melanoma skin cancer in mice by reducing inflammation, inhibiting cell proliferation, and blocking specific signaling pathways associated with tumor growth.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

In this study, exosome-mimetic nanovesicles derived from neural progenitor cells promoted hair follicle regeneration in mice by activating the Wnt/β-catenin signaling pathway.

This study found that dexamethasone treatment reduced cell viability and growth factor expression in human dermal papilla cells, suggesting it inhibits hair growth.
