This study observed that higher prenatal androgen loads were associated with more severe alcohol dependence in male patients and linked to behaviors of pregnant women that may influence their children’s androgen exposure.

Mutations in the ACTB gene cause Becker’s nevi and may lead to muscle issues in Becker’s nevus syndrome.

This study suggests that αMSH may play a regulatory role in human dermal papilla cells, potentially influencing immune and inflammatory responses in hair follicles, which could contribute to inflammatory alopecia.

This review evaluates various kits for isolating platelet-rich plasma using established processing standards and finds they enable compliance with consensus quality criteria; ongoing research is needed to refine these procedures for improved consistency and safety.

AGD1 is important for root hair development in Arabidopsis, working with phosphoinositide signaling and the actin cytoskeleton.

This study observed that in hormone-starved prostate cancer cells, the androgen 5alpha-dihydrotestosterone rapidly induces matriptase activation and shedding, which involves androgen receptor signaling and requires both transcription and protein synthesis.

This study found that the JMJD3/NF-κB-Notch1 pathway plays a crucial role in regulating keratinocyte migration and skin wound healing, with Notch1 affecting key genes involved in cell migration.

This study found that activin A significantly enhances wound healing by stimulating granulation tissue formation and re-epithelialization in mice, and suggests potential in developing treatments for stroke and brain trauma.

This study found that PPAR alpha, -delta, and -gamma are expressed in human hair follicle cells, and clofibrate exhibited a beneficial effect on hair follicle survival in culture within a specific concentration range.

This study found that after injury, the bone marrow microenvironment's increased Wnt10b expression supports hematopoietic stem cell regeneration by enhancing Wnt signaling, revealing a vital interaction during recovery.

This study found that dual 5α-reductase inhibitors in rats decreased sperm quality and led to reduced pregnancy success, suggesting potential for use in male contraception.

This article contains additional supporting information available online but presents no new research findings.

This study found that Acvr1b signaling is crucial for both hair follicle development and cycling in mice, with the genetic disruption leading to hair loss and a thickened epidermis.

This study found that mouse FLRG protein, a secreted glycoprotein, is expressed in certain tissues and plays a role distinct from follistatin during wound healing, suggesting different functions in vivo.

This study found that subcutaneous isotretinoin in male hamsters reduced sebaceous gland size without affecting other androgen-dependent skin structures, while etretinate had no effect.

This study observed that Aconiti Ciliare Tuber extract may promote hair growth in mice by activating the Wnt/β-catenin signaling pathway.

In this study, the researchers reported that activin B combined with bone marrow-derived mesenchymal stem cells enhanced wound healing and hair follicle regeneration in rats by promoting cell migration through the ERK and JNK pathways.

This review discusses the role of activin signaling in hair follicle formation, hair growth cycling, and skin healing, but presents no new clinical findings.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

This study found that activin B promotes epithelial wound healing in mice through the RhoA-Rock-JNK-cJun signaling pathway, suggesting a potential therapeutic role for activin B in wound repair.

This study found that extracellular vesicles from stimulated human dermal fibroblasts enhanced hair follicle growth ex vivo by activating dermal papilla cells and involving the Norrin and β-catenin pathways.

This study found that activating liver X receptors with an agonist reduced skin fibrosis in experimental models, particularly in inflammation-driven conditions, by inhibiting macrophage infiltration and interleukin-6 release.

In this study, pioglitazone treatment in patients with lichen planopilaris showed limited success, with significant improvement seen in only a minority of cases.

This study found that hypaphorine alters cytoskeletal organization in Eucalyptus globulus root hairs, contributing to reduced root hair elongation by possibly disrupting vesicle delivery needed for growth.

This study found that adrenal sex hormone levels were elevated in neutered dogs with hypercortisolemia, except for testosterone, highlighting the importance of ruling out hypercortisolemia when diagnosing adrenal hyperplasia syndrome.

This study reported that patients with alopecia areata experienced significant increases in work productivity loss and activity impairment due to worsening emotional symptoms, highlighting a need for better treatments.

In this study, Treg depletion impaired skin wound healing in mice, potentially by altering the cytokine environment and expanding certain T-cell populations, disrupting the normal healing process.

This research found that activating a KrasG12D mutation in mice led to skin thickening, papillomas, and hair growth issues, suggesting that even rare KRAS mutations can mimic human RAS/MAPK syndrome symptoms.

In this study, mannosylerythritol lipids from soybean oil notably increased fibroblast and papilla cell viability, suggesting potential as a hair growth agent.

This study found that women with polycystic ovary syndrome have significantly higher plasma levels of thrombin-activatable fibrinolysis inhibitor and other hemostatic markers compared to age- and BMI-matched healthy controls.
