The research identified six functional hair keratin genes and four pseudogenes, providing insights into hair formation and gene organization.

This study used proteomic techniques to analyze human hair proteins, revealing keratin heterogeneity and identifying posttranslational modifications, such as cysteine trioxidation and methylation.

This study suggests that human keratin fiber matrix has a well-defined nano-scale grainy structure rather than being amorphous, with grain size influenced by chemical treatments, temperature, humidity, and follicle-level factors.

This case report describes an ossifying pilomatrixoma found in a 15-year-old girl, confirmed via histopathological examination after imaging indicated a subcutaneous mass on her cheek.

This study found that androgen impacted glucocorticoid signaling in the mouse brain only in the prefrontal cortex and substantia nigra, suggesting limited interaction between these hormones at high corticosterone levels.

In this study, pilomatricoma, a benign skin tumor from hair follicle matrix cells, is highlighted as an important consideration when diagnosing painless, firm subcutaneous nodules, with accurate diagnosis relying on histopathological examination.

This case study reports on a rare benign skin tumor known as Pilomatricoma in the lower left orbital region of a 32-year-old male, highlighting its characteristic histopathological features and emphasizing the importance of surgical excision for successful treatment and minimal recurrence risk.

This study identified a mutation in the KRTHB6 gene in two monilethrix families of Indian origin, linking specific genetic variations to different severities of hair defects within the families.

This study analyzed the genetics of the patchiness phenotype in New Zealand rabbits and found that the gene KRT82, with identified SNPs in its promoter, may serve as a potential biomarker for breeding these rabbits.

In this study, researchers observed that reproductive experience in female rats altered fear memory and medial prefrontal cortex (mPFC) activity, with pregnant and parous rats showing impaired fear recall compared to nulliparous controls, highlighting the influence of pregnancy-related neurosteroids on cognitive function and brain activity.

This study identified genetic, biological, and technical factors that influence circRNA expression in the human brain, connecting these factors to potential genetic risk for diseases like schizophrenia and type II diabetes.

This study found that tinea capitis was the most common cause of scalp hair loss in children, affecting over half of cases, followed by alopecia areata, seborrheic dermatitis, and other conditions.

This study identified the presence of recognizable organelles, such as lysosomes and mitochondria, in both the keratinized fiber and the hardened inner root sheath of the Romney wool follicle.

This study found that human hair exhibits significant deformation in its intermediate filaments under strain, with recovery taking about 1000 minutes, suggesting a self-healing period post-mechanical stress. Additionally, cuticle scales deform much less than the cortex, and the Poisson ratio aligns with soft matter properties.

In this study, researchers successfully cloned the KAP24.1 gene from sheep to analyze its expression in skin and hair follicles, finding that Mountain-type Hetian sheep showed the highest levels of expression and that androgen concentration significantly influenced KAP24.1 protein expression.

This research found that Dlx3 plays a central role in hair formation and regeneration, with its absence leading to alopecia through disrupted differentiation and signaling pathways.

mHa2 and mHa3 keratins have different structures and roles in mouse hair and tongue tissues.

This study identified and characterized a murine type II hair keratin, demonstrating its presence in specific cells of hair and tongue tissues.

This study describes the presence of holes in hair fibers, absent in hair follicles, likely forming from daily care actions and removal of extractable substances.

This case report describes an 18-year-old man with pili annulati, characterized by a "shagreened" appearance of the hair shaft with alternate bright and dark bands and wide holes throughout the cortex.

This study identifies a specific cell population, PDGFRα+/Sca1+/CD34+ mesenchymal cells, which play a crucial role in regenerating hair follicles by promoting the downgrowth phase of the hair cycle, offering insights into organ morphogenesis and stem cell niches essential for adult hair regeneration.

This article discusses the biology of cosmetic aging and the chemical pathways involved, emphasizing research advancements that aid clinicians in rejuvenating skin and increasing scalp hair density, but it provides no new results.

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.

K39 and K40 are the last keratins expressed in hair development, completing the hair keratin catalog.

This study found that transcription factors HOXC13, LEF1, and FOXN1 repress DSG4 transcription, with the Notch pathway possibly involved in maintaining DSG4 expression in hair follicles.

This study observed that lipids in human hair accumulate in specific areas and do not significantly impact water permeability, highlighting the utility of AFMIR for studying complex biomaterials.

In this study, the researchers identified the specific subcellular localization of the protein S100A3 in the endocuticle and cortex of human hair shafts.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

This study found that specific genetic changes in both coding and noncoding regions may have independently driven the evolution of hairlessness in various mammalian species through accelerated evolution.
