This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

Hair follicles in people with alopecia have lower levels of a key blood vessel growth protein.

This study optimized conditions for extracting saponins from Eclipta prostrata, achieving maximum yield with specific ethanol concentration, time, temperature, and liquid/solid ratio.

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 the historical and current use of ribosome-inactivating protein-expressing plants in traditional medicine across various cultures and regions, highlighting their role despite a lack of scientific validation.

This review discusses recent research and applications of RADA16 and RADA16-based peptide scaffolds in biomedicine, including their roles in tissue repair and drug delivery, but reports no new clinical results.

Oestrogen and thyrotropin-releasing hormone affect prolactin and its receptor in human skin and hair, suggesting new treatment options for related conditions.

This review explores the potential of using genetically-manipulated stem cells as both therapeutic agents and gene delivery vehicles for enhanced wound regeneration, but it reports no new clinical results.

In this study, DHT was found to inhibit hair growth in mice by decreasing IGF-I production in dermal papillae through reduced sensory neuron stimulation.

This study found that the protein hairless acts as both a corepressor and coactivator of the vitamin D receptor, influencing gene transcription in a ligand-selective manner.

This study found that 0.7% apple procyanidin oligomers applied externally for six months significantly increased hair growth in men with male pattern baldness compared to placebo, with no observed adverse effects.

This study identified overexpression of certain immune-related genes and underexpression of genes in specific signaling pathways in premature androgenetic alopecia, suggesting potential new therapeutic targets.

The conclusion is that androgenetic alopecia and senescent alopecia have unique gene changes, suggesting different causes and potential treatments for these hair loss types.

Minoxidil reduces lysine hydroxylase in skin cells.

In this study, the methanol extract of Cercidiphyllum japonicum heartwood was found to stimulate the proliferation of mouse hair epithelial cells, with several isolated compounds showing significant proliferative activities.

In this study, researchers found that ligand homodimerization controls the receptor binding specificity of the FGF9 subfamily, preventing off-target activation of FGFR "b" isoforms.

Researchers found an RNA transcript that might help control a growth factor linked to tumor development.

This review discusses the cosmetic use and safety of Hypericum Perforatum Extract and Oil, finding that current data are insufficient to support their safety in formulations due to a lack of comprehensive testing.

This study found that resveratrol and fisetin promoted hair growth in mice by inducing telomerase reverse transcriptase expression, which activates hair follicle stem cells and transitions follicles from a resting to a growth phase.

This review discusses the role of steroid sulfatase in steroid hormone metabolism and highlights the need for more research on its expression and regulation, especially regarding hormone-dependent tumors.

This study found that IFN-γ plays a critical role in T cell activation and the pathogenesis of alopecia areata in C3H/HeJ mice.

This review discusses the effects of minoxidil on human skin fibroblasts, reporting its potential to inhibit lysyl hydroxylase activity and DNA synthesis, suggesting it may have antifibrotic applications for collagen-related skin conditions.

In this study, partially purified apple polyphenols were found to inhibit preadipocyte differentiation in mouse cells by reducing GPDH activity and triglyceride accumulation.

This report describes a case of Birt-Hogg-Dube syndrome with manifestations including multiple fibrofolliculomas, acrochordons, and renal oncocytoma.

This study identified a new gene, mrp4, in mice, which suggests it may have a unique role in the growth and development of hair follicles in the ears and tails.

This study found that Prosopis farcta is a rich source of phenolic compounds with strong antioxidant activity, suggesting its potential for use in food, beverage, feed, and pharmaceutical applications.

In this study, applying deer antler velvet extract-loaded niosomes and microspicules serum to the scalp significantly improved hair growth, melanin content, and skin hydration over 14 to 30 days without causing skin irritation.

In this study, EGCG from green tea promoted mink hair follicle growth and cell proliferation at specific concentrations, potentially through activation of Shh and AKT signaling pathways.

This study found that thermal hair-straightening devices significantly damaged the cuticle and cortex of virgin Asian and Caucasian hair, with Asian hair experiencing more protein loss than Caucasian hair.

This study found that a papain-containing cream had a significantly greater depilatory effect and altered skin morphology more than a papain-containing gel when applied to mice.
