This article reviews the genetic and protein interactions involved in hair growth, highlighting regulatory sequences, expression patterns, and potential genetic modifications, but presents no new experimental findings.

This study concluded that heterozygosity for CYP21 mutations is associated with higher mean and free testosterone levels in women but does not significantly increase their risk of developing clinically evident hyperandrogenism.

This study found that the PLC2 gene plays a critical role in auxin-mediated root development in Arabidopsis, influencing root growth and PIN2 distribution.

This study found that NFI-C plays a crucial role in the transition from the telogen to anagen phase of the hair follicle cycle, affecting hair growth initiation in mice.

This study found that overexpression of the transcription factor NFIC may enhance the proliferation and differentiation of stem cells from the apical papilla, suggesting its potential role in dentin/root regeneration.

This study designed a 66 K SNP chip using solution hybrid selection for cashmere goats, reporting SNP call rates between 95.3% and 99.8% and demonstrating its utility in genomic analyses, suggesting potential application for other species.

This study describes a method for labeling and tracking hair follicle stem cells in mouse skin using a Cre/lox recombination system with tamoxifen, providing insights into stem cell behavior and contribution to tissue regeneration.

This study identified a novel splice site mutation in the LIPH gene associated with autosomal recessive woolly hair, contributing to understanding the genetic basis of this condition.

This study demonstrated that human dermal mesenchymal stem cells can be differentiated into cardiomyocytes using 5-azacytidine, suggesting potential future applications for treating myocardial infarction.

This study reported that heterozygous carriers of a mutation in the human hairless gene did not differ from healthy homozygotes in the pattern of androgenetic alopecia.

This study found that the Plcd3(mNab) mutation in mice worsens the alopecia caused by Plcd1 loss, suggesting synergistic effects between Plcd1 and Plcd3 on hair follicle health.

In this study, researchers identified a novel STS gene (c.287G > A; p.W96*) mutation in Pakistani individuals with X-linked ichthyosis, expanding the understanding of its genetic causes and aiding in genetic counseling.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.

This study found that cashmere has a significantly smaller mean fiber diameter compared to sheep and goat wool, and identified key proteins that may influence this difference.

In this study, researchers found that heterozygous carriers of a mutation in the hairless gene showed no difference in the pattern of androgenetic alopecia compared to unaffected individuals.

This study found that TLR2 expression in hair follicle stem cells is crucial for hair follicle maintenance and regeneration, with TLR2-dependent activation potentially offering new therapeutic approaches for hair loss prevention through mechanisms involving immune pathways and CEP administration.

This study suggests that Annexin A2 isoform 2 might play a role in regulating the proliferation and growth of dermal papilla cells, potentially impacting the hair follicle growth cycle.

In this study, the expression of Gnαs was significantly higher in black mice compared to white mice, suggesting its potential involvement in coat color formation in mice.

This study found that patients with androgenetic alopecia showed distinct scalp bacterial imbalances compared to healthy individuals, which were associated with unhealthy lifestyles. These microbial changes might contribute to follicular inflammation, potentially accelerating hair loss in these patients.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

This study reported that, in a laboratory setting, araliadiol derived from Centella asiatica activated antioxidant pathways, mitigating urban particulate matter-induced oxidative stress and skin damage.

This study reported a significant association between the SNP rs2479106 in the DENND1A gene and PCOS in Saudi Arabian females, while no association was found for SNPs rs10818854 and rs10986105.

In this study investigating goat herds in Zambia, both mange and orf were detected, but with low occurrence linked to diagnostic challenges and mild clinical signs; further research, especially in conditions favoring mange mites, is recommended to better understand and manage these diseases.

This study found that hair with lower levels of keratin associated proteins reduced the foreign body response in mouse subcutaneous implant tests compared to hair with higher keratin levels.

This study found that alopecia areata patients with a CCHCR1 gene variant had higher recurrence rates and structural abnormalities in hair compared to those without the variant.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.

This study identified changes in transcription factor gene expression across various signaling pathways during inner ear hair cell regeneration in birds, revealing patterns and potential new pathways for future investigation.

In this study, thymosin beta4 over-expression in transgenic mice was linked to accelerated hair growth and abnormal tooth development, suggesting roles in hair and tooth physiology.

In this study, researchers found that petroleum ether extract of Eclipta alba significantly stimulated follicular keratinocyte proliferation and reduced TGF-β1 expression in nude mice, suggesting potential use for certain types of alopecia.
