This study found that somatic mosaic mutations in the doublecortin gene may cause subcortical band heterotopia in male patients, and molecular analysis using hair roots is a useful detection method.

Keratin in mouse hair follicles is complex and plays specific roles.

In this study, researchers found that AGD1 is crucial for membrane recruitment during root hair development in Arabidopsis thaliana, with its pleckstrin homology domain essential for targeting specific plasma membrane regions.

This study found that root hair length and density in rice are controlled by distinct genomic regions, with 18 regions identified but no overlap between the traits.

This study developed a non-destructive X-ray fluorescence technique to quantitatively analyze elemental content in human hair and constructed a database of element concentrations in healthy Swedish, Caucasian individuals.

This study found that hair root sheaths can be accurately typed for erythrocyte acid phosphatase, adenylate kinase, and adenosine deaminase, consistent with blood typing results from the same donors.

The study found that sonication washing of hair roots with fewer than 50 visible nuclei could reduce the number of nuclei available for DNA extraction and STR typing, suggesting that for laboratories focused on nuDNA analysis, a gentler washing method might be adequate.

This study found that hair canal and follicle diameters, outer root sheath area, and terminal-to-vellus hair ratios were significantly reduced in androgenetic alopecia patients compared to normal controls.

This study observed that interferon β secreted by dermal papilla cells may negatively regulate the growth of outer root sheath cells in hair follicles.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

This study found that shed hairs from the root significantly outnumber broken hairs during hair fall, particularly in Chinese male and female participants, with shedding predominantly occurring during washing.

This study provides evidence for K1 and K10 derivatives' presence in the inner root sheath and hair cuticle, suggesting that these hair follicle parts may follow familiar keratinization principles.

This study found that KAP7.1 and KAP8.2 genes were significantly more expressed in secondary hair follicles than primary follicles, suggesting their role in regulating cashmere fiber diameter.

This research observed that during the catagen phase, the inner root sheath of hair follicles becomes an early target, highlighting its potential role in maintaining hair follicle homeostasis.

This study suggests that the inner root sheath plays a significant role in maintaining hair follicle homeostasis during the catagen phase's early stages.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This study found that in androgenetic alopecia patients, there is enhanced expression of type 2 TGF-β and type II receptors in hair follicles, suggesting a link to hair growth cycle changes.

In this study, researchers observed distinct morphological differences in hair follicles of mutant mouse genotypes, influenced by the expression levels of keratin2-6g, which is essential for proper hair follicle development.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This study detailed the structure and amino acid composition of sheep trichohyalin, noting its presence in various tissues and suggesting a possible functional role beyond structural support in hair follicles.

This study found that DNA is present at low levels in human hair shafts, with higher amounts near the root, and that its levels decrease after surfactant washing and colorant treatments.

This study observed that in Japanese females, hair lipid composition showed significant correlations, suggesting CH and CERs may act as a barrier against sebum-derived lipids.

This study used single-cell RNA sequencing to map the cellular composition of sheep hair follicles, revealing differentiation pathways and potential molecular mechanisms for wool curvature, which may inform sheep breeding.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

This study found that the S100A3 gene is exclusively expressed in hair follicle cells differentiating into hair shaft components in mice, suggesting its important role in hair formation.

In this study, Satura® Rosta remedy was found to significantly increase hair follicle size, hair root volume, and skin thickness in mice, potentially by prolonging the anagen phase, with notable hair regrowth observed in older mice with alopecia.

This study found that the vitamin D receptor is crucial for initiating the postnatal hair follicular cycle in mice, preventing alopecia associated with its inactivation.

This study found that the Gsdma3 gene is necessary for normal hair follicle differentiation in mice, with its mutation leading to progressive hair loss and defects in hair structure.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.
