This study concluded that among men with normal testosterone levels, a small increase in serum dihydrotestosterone may reduce symptoms of hypogonadism, suggesting its potential diagnostic use after ruling out hypogonadism.

This study found that high-dose pterostilbene potentially reduced prostate hyperplasia and had strong antioxidant effects in male rats with benign prostatic hyperplasia, suggesting it might be more effective than vitamin C and resveratrol in similar contexts.

This review discusses the similarities between wound healing and embryonic development, focusing on signaling pathways and their potential for developing new wound healing strategies, and reports no new clinical results.

This review investigates molecular mechanisms behind PCOS pathogenesis and discusses potential therapies, but reports no new clinical results.

High testosterone to epitestosterone ratio in hair could predict male-pattern baldness.

This source reviews mechanisms and existing treatments for hair aging, highlighting factors like oxidative stress and DNA repair defects that affect hair follicle and stem cell function, and discusses research limitations and future directions in the field.

This research examined krill oil's effects on benign prostatic hyperplasia and found that it inhibited the growth of prostate cells in vitro and reduced prostate size and weight in a BPH rat model, suggesting potential as a prophylactic or therapeutic agent for BPH.

This study demonstrated that blocking the Sonic hedgehog signaling pathway in mice led to reversible inhibition of body coat hair morphogenesis, while whisker development was unaffected.

This review summarizes the current understanding of Wnt signaling in relation to its roles in tissue regeneration and cancer progression and discusses recent medical advancements targeting this pathway for therapeutic purposes.

This review discusses the role of Wnt/β‐catenin signaling in stem and cancer stem cell maintenance and its involvement in the development and regeneration of various organs, but reports no new experimental results.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This study found that exercise decreases the expression of 5αR1, thereby enhancing the PI3K/AKT signaling pathway in PCOS rats.

In this study, overexpression of YAP1 was found to promote adipogenic differentiation of goat adipose-derived mesenchymal stem cells by up-regulating LATS2 expression and activating the Hippo pathway's negative feedback loop.

This study found that hair from mice with the Naked trait mutation has significantly lower levels of glycine and tyrosine, suggesting a deficiency in a specific protein fraction.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

In this study, researchers overexpressed Lrig3 in mouse skin and observed hair loss linked to changes in skin protein profiles and signaling pathways, suggesting a potential role for Lrig3 in maintaining skin homeostasis.

This review discusses various therapeutic strategies targeting platelet-derived growth factor signaling in diseases like cancer and atherosclerosis, and evaluates existing treatments without presenting new clinical data.

This review discusses the importance of androgen production and metabolism in hyperandrogenism, the use of specific serum markers for diagnosis, and the need for improved assays for clinical testing, but reports no new results.

This review discusses the pathways of androgen biosynthesis and reports no new findings, highlighting the need to understand the interplay between the classic and backdoor pathways.

This study suggests that in SZ95 sebocytes, a pathway for DHT biosynthesis does not require testosterone as an intermediate, potentially impacting the treatment of androgen-sensitive skin conditions.

This study suggests that UMPP activation is a key signaling pathway in differentiating primary and secondary hair follicles in cashmere goats.

This study observed that the NOTCH signaling pathway may contribute to the development of fibrosis in systemic sclerosis by affecting epithelial cell changes, and inhibiting this pathway could prevent fibrosis in experimental models.

This article reviews the roles and mechanisms of stem and progenitor cell migration in adult organs for tissue homeostasis and regenerative medicine, but reports no new experimental results.

This review discusses emerging targets for developing drugs to treat hair loss and reports no new clinical results; the authors emphasize the potential for therapies that regenerate hair follicles.

This study found that inhibiting AP1 transcription factor activity in the suprabasal epidermis of mice alters keratinocyte gene expression, reducing barrier integrity and mimicking human keratoderma.

In this laboratory study, procyanidin B2 inhibited early plant growth and biochemical responses in wheat seedlings treated with lipopolysaccharides from Azospirillum brasilense, suggesting that plant response activation requires LPS recognition by plant cells.

This review assessed experimental studies on herbs used for alopecia, identifying potential mechanisms involving hair cycle management and keratinocyte processes, but highlighted a need for improved evidence on quality control and toxicity of these herbal treatments.

In this study, injectable platelet-rich fibrin (i-PRF) was found to enhance the proliferative, migratory, and hair-inducing abilities of dermal papilla cells more effectively than platelet-rich plasma through the TGF-β/Smad pathway.

In this animal study, PRF enhanced the repair of chronic wounds in rats by reducing inflammation and promoting collagen deposition and new blood vessel formation, potentially through activating the Wnt/β-catenin signaling pathway.
