TGF-β signaling is essential for new hair growth after wounds.

This study suggests that Gambogic Amide may act as an anti-hair greying and hair growth-promoting molecule in human hair follicles in vitro by maintaining pigmentation and stimulating hair shaft elongation.

Overexpressing the epigen gene in mice leads to enlarged sebaceous glands and greasy fur.

This study found that ephrin-A3 accelerates hair follicle development and increases hair follicle density in neonatal mice, suggesting its involvement in hair growth regulation.

This study found that the leaf extract of Tectona grandis and its major bioactive constituents moderately inhibit the 5α-reductase enzyme, which is linked to androgenetic alopecia, and also possess anti-inflammatory properties, showing promise as dual-action candidates for managing this condition.

A deep learning model was developed to help diagnose trichothiodystrophy by analyzing hair patterns.

This study concluded that CNS1-dependent peripheral Tregs do not significantly impact type 1 diabetes in the NOD mouse model, with thymus-derived Tregs being the primary regulators.

This invention reports piperazine derivatives as potent inhibitors of type 3 17β-hydroxysteroid dehydrogenase, suggesting potential therapeutic applications in treating prostate cancer, acne, and androgenic alopecia.

In this study, TRPV1 signaling was found to play a critical, previously unrecognized role in human sebocyte biology, and targeting this pathway may offer a new approach for managing inflammatory sebaceous gland disorders like acne.

In laboratory studies on mice, Abstract UT-018, a stem cell chemoattractant formulation, was reported to significantly enhance wound healing and promote hair regeneration through mechanisms involving improved tissue formation, collagen organization, and follicular development.

GFC is more effective than PRP for treating hair loss.

This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This study generated a Dct-H2BGFP mouse model that allows for effective identification and isolation of melanocytic cells in vivo, facilitating research into their molecular and biological properties.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This study reported that topical ω‐0‐acylceramide improved skin barrier function in Jack Russell Terriers with TGM1-deficient autosomal recessive congenital ichthyosis, normalizing skin pH and reducing transepidermal water loss.

This study presents the G4 transgenic mouse model, which suggests a direct link between polycystic ovary syndrome and the Gm10800 gene, offering a valuable tool for understanding the disease and testing treatments.

This study found that genes encoding mouse high-glycine/tyrosine proteins show distinct spatial and temporal expression patterns in hair follicles, suggesting diverse protein distribution during hair growth cycles.

This study found that the Chinese herb Ligustrum lucidum may enhance expression of hair growth-related genes, HGF and VEGF, in cultured mouse hair follicles.

In this study, TC-1 cells, resembling stromal cells formed by epithelial-mesenchymal transition, significantly affected the behavior of normal human keratinocytes, supporting the role of stromal cells in tumor progression.

In this study, intradermal injection of botulinum toxin was associated with increased hair growth in men with androgenetic alopecia through the suppression of TGF-β1 secretion from dermal papilla cells.

This study found that γδTregs can prevent and treat alopecia areata in a mouse model with human scalp transplants, suggesting potential for cell-based therapies in autoimmune diseases like alopecia.

This study suggests that proteins CHI3L1 and CXCL5, secreted by recovery-state dermal papilla cells, may promote hair growth by stimulating the proliferation of outer root sheath cells.

This study found that cPPARγ and dnPPARγ isoforms are differentially expressed in healthy human skin, suggesting that PPARγ modulators may have compartment-specific effects depending on isoform presence.

This study found that conditional expression of TGFβ1 in mice affects epidermal and hair follicle growth, with chronic expression causing severe alopecia and a negative feedback loop involving Smad7.

This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

This study found that the Arabidopsis cation chloride cotransporter CCC1 is critical for regulating pH in the trans-Golgi network/early endosome, impacting plant growth and stress response.

This study reported that IL-6/STAT3 signaling influences p63 isoform expression in keratinocytes and is involved in wound-induced hair follicle neogenesis, highlighting the interplay between immune and developmental pathways.

In this randomized, placebo-controlled study, Titagen® was found to improve skin, hair, and nail health in adults consuming 5g daily, and reduce pain and improve quality of life for osteoarthritis patients taking 10g daily, without related adverse events.
