In this study, topical application of Thuja orientalis extract promoted hair growth by inducing the anagen phase and increasing hair follicle size and number in telogenic mice.

This study suggests that frontal fibrosing alopecia is a highly inflammatory disease involving TH1 and JAK-STAT pathways, without reduced hair keratins, highlighting JAK-STAT signaling as a potential therapeutic target.

In this study, Wnt-3a was found to play an important role in partially maintaining and expanding epithelial skin stem cells in vitro, suggesting potential for in vitro stem cell culture without feeder cells.

This review provides guidance on using two-photon microscopy for real-time and long-term visualization of stem cell activity in live mice skin, focusing on its application in researching skin and stem cell biology.

This narrative review describes the components of human hair and their nutritional importance but reports no clinical results; the authors suggest dietary sulfur amino acids are essential for hair health.

This study found that Rubus coreanum extract promotes hair growth in mice, but its effects are not due to inhibition of specific enzymatic activities or growth factor expression.

This study found that TGFbeta is a key pathway causing age-related loss of dermal fat's antimicrobial function, suggesting that targeting TGFBR might help restore skin defense against infections in older age.

This review discusses the biology and development of skin melanocytes, but reports no new clinical findings.

This review examines apoptotic and anti-apoptotic mechanisms in skin homeostasis and related diseases but presents no new research findings.

This study found that normal human melanocytes can be protected from apoptosis through both PI 3-kinase/Akt-dependent and independent pathways, with insulin and TPA offering nearly complete protection.

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 review discusses how neuroendocrine pathways influence keratin regulation in human skin and hair follicles and suggests these pathways as potential targets for new treatments of skin disorders, but reports no clinical results.

Acankoreoside J from Acanthopanax koreanum may help promote hair growth.

This study observed that reduced activation of SMAD2/3 proteins in cutaneous squamous cell carcinoma tissue compared to adjacent tissue may indicate a tumor suppressor role in disease progression.

This study found that patients with acne vulgaris had higher serum IGF-1 levels and more intense FoxO1 and mTOR expression than controls, suggesting their role in acne pathogenesis.

This study identified distinct gene expression patterns in wool follicle bulbs that may play important roles in wool follicle cycling and regeneration in sheep.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study found that transgenic mice expressing a mutant CYLD protein lacking deubiquitinase function showed signs of premature aging and spontaneous tumor development, likely due to over-activation of specific molecular pathways and chronic inflammation.

This study found that VEGFR-2 activation may play a role in hair follicle differentiation, proliferation, and apoptosis by co-expressing with several key proteins in normal human scalp skin.

This study identified a specific genetic variant in the CCHCR1 gene that may contribute to alopecia areata through impaired keratinization, suggesting an alternative mechanism beyond autoimmune causes.

This study reviews the role of the zinc finger protein CXXC5 in cellular signaling and its implications for cancer, discussing how its dysregulation is linked to various physiological and pathological processes, as well as potential therapies targeting CXXC5.

This study reports that high expression of proteins ST14 and TMEFF1 in ovarian cancer correlates with higher tumor malignancy and worse prognosis, and reveals an interaction where ST14 regulates TMEFF1 to promote cancer cell proliferation, migration, and invasion.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This study found that doxorubicin induces hair follicle apoptosis through TRAIL receptor signaling, providing insights for managing chemotherapy-induced hair loss.

This study identified a mutant in Arabidopsis with shorter root hairs due to early growth cessation, implicating the IRE gene in regulating root hair growth duration.

This review discusses the role of oxidative stress in hair greying and suggests that understanding melanocyte susceptibility at different follicular locations may help develop therapies for preventing and reversing the process; it reports no new experimental results.

This study identified key genes and pathways involved in the growth and development of forest musk deer hair follicles, providing insights into molecular regulation and laying groundwork for future research on related diseases.

This study found that colchicine treatment significantly reduced hair fiber elongation in cultured hair follicles and altered protein expression and activity in dermal papilla cells, suggesting a role for the ubiquitin-proteasome system in its effects.

In this study, silencing P-cadherin in human scalp hair follicles reduced melanogenesis and associated protein expression, suggesting P-cadherin is crucial for normal hair pigmentation via GSK3β-mediated Wnt signaling.

This study found that carbonic anhydrase II was significantly upregulated in human keratinocytes when treated with toll-like receptor 3 agonist and Th2 cytokines, suggesting its potential role in inflammatory skin conditions.
