This study found that HPV8-induced actinic keratoses may mechanistically involve Lrig1+ hair follicle keratinocyte stem cells, with the E6 gene promoting downstream STAT3 activity in a mouse model.

This study found that 5-bromo-3,4-dihydroxybenzaldehyde (BDB) promoted hair growth in rat vibrissa follicles by activating Wnt/β-catenin and autophagy pathways and inhibiting the TGF-β pathway in dermal papilla cells.

This study found that the 5α-steroid metabolite profile in men with inherited 5α-reductase deficiency is similar to those taking the drug finasteride, suggesting the gene affects multiple steroid substrates.

PP405 may help hair growth by activating hair follicle stem cells.

In this study, transgenic mice expressing a truncated form of latent transforming growth factor-β-binding protein exhibited altered hair cycles due to increased active transforming growth factor-β, impacting keratinocyte proliferation and hair cycle phases.

This study found that finasteride effectively inhibits the enzymatic activity of human steroid 5 alpha reductase type II in newly established CHO cell lines.

In this study, researchers observed that acute stress increased levels of the enzyme 5αR2 in the medial prefrontal cortex of male rats, affecting stress reactivity, but this effect was not seen in females.

This study suggests that BTP levels in cerebrospinal fluid might help diagnose CIDP and predict therapy response but require validation in larger cohorts.

This study found that using SH-SY5Y cell lysate in Western blot analysis may improve the diagnosis of Satoyoshi syndrome by providing more consistent and clear immunoreactive band patterns compared to brain homogenate, potentially leading to earlier diagnosis and treatment.

This study found that the Hr gene loss and positive selection for the FGF5 gene in cetaceans likely contributed to hair loss as these animals adapted to aquatic environments.

In this case report, researchers described a female child with total alopecia due to a mutation in the SNRPE gene, emphasizing the need for updated genetic testing as knowledge advances to avoid diagnostic delays in hereditary nonsyndromic hypotrichosis.

This study reported that depleting the pro-apoptotic protein Bax in hair follicle stem cells enables these cells to kill nearby viable cells by sequestering TNFα, which increases the stem cell pool and accelerates tissue regeneration, suggesting potential implications for therapies targeting tissue repair and cancer.

This study reported that heterozygosity for FHIT affects mice's susceptibility to spontaneous alopecia areata and to certain preneoplastic lesions induced by benzo[a]pyrene, but does not change how they respond to budesonide and N-acetyl-L-cysteine.

This case report describes a 12-year-old boy with severe skin scaling due to novel compound heterozygous null truncation mutations in the TGM1 gene, resulting in loss of transglutaminase 1 activity.

This study found that Smad4 is crucial for satellite cell amplification during skeletal muscle regeneration, with aged cells exhibiting less Smad4 and reduced regenerative capability in mice.

The Trichodysplasia spinulosa virus protein can cause abnormal hair growth in mice.

This study identified intramembrane proteolysis as a key feature of Astrotactin2 maturation, providing insights into its role in planar cell polarity hair patterning.

This study found significantly higher P-Smad2 levels in both lesional and nonlesional skin of organ transplant recipients, suggesting elevated TGF-β signaling might contribute to their increased cancer susceptibility.

This study concluded that specific SNPs in the TRPS1 gene significantly alter its protein structure, affecting interactions and contributing to the development of congenital hypertrichosis.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study observed that mice with a whole-body deficiency of Cystathionine-β-synthase developed severe hyperhomocysteinemia and related mild symptoms without increased mortality, indicating HHCy may not directly cause end organ damage.

This study found that two new progesterone derivatives showed higher antiandrogenic effects and 5α-reductase inhibition than finasteride in hamsters, particularly reducing seminal vesicle weight and flank organ size.

This study observed that K5Cre +/+ transgenic mice develop a distinct phenotype characterized by wavy hair, curly whiskers, and an increased rate of papilloma malignant transformation.

In this study, researchers found that the cell surface protein Lrig1 plays a crucial role in regulating the suppressive function of regulatory T cells, suggesting it as a potential target for treating autoimmune diseases, as evidenced by experiments in mouse models.

This study found that platelet lysate significantly improved hair growth and follicle performance in both experimental settings and AGA patients, showing results comparable to platelet-rich plasma.

ABS-201 may effectively promote hair growth in men by targeting the prolactin receptor.
