This study achieved successful cloning of the ovine keratin associated protein 6-1 gene, which may facilitate future research on transgenic animals and hair follicle gene regulation.

This study identified a new transcriptional repressor, Zfp157, as a target of Stat6 in the mammary gland, expressing in various tissues during mouse embryogenesis and adulthood.

This study demonstrates that Krt15 marks long-lived, multipotent, and injury-resistant crypt cells in the small intestine, which may serve as the cell of origin in intestinal cancer.

This study identified a radio-resistant population of Krt15+ stem cells in the mouse small intestine that can initiate tumors, suggesting potential targets for colon cancer therapy.

Human melanocytes in skin and hair follicles don't express keratin 16 or 6 naturally.

This study found that regulatory sequences crucial for inducing K6a expression in response to epidermal injury are located in specific upstream regions of the K6a gene in transgenic mice.

This study identified two key pentapeptide quasi-repeats in human keratin-associated proteins, which are similar to motifs found in sheep wool.

This study reports identifying 12 candidate genes potentially involved in regulating hair follicle development in cashmere goats, which could contribute to improving cashmere production.

This study observed that both ritlecitinib and brepocitinib improved scalp biomarkers in patients with alopecia areata, with associations to hair regrowth seen in this phase 2a trial.

In this study, the researchers reported extensive gene loss and high pseudogenization rates of α-keratin genes in cetaceans compared to terrestrial mammals, likely linked to hair loss and aquatic adaptations.

This study observed that differences in the expression of genes related to lipid metabolism may play a major role in determining wool fiber diameter in sheep.

This study found that oral JAK3 and TYK2/JAK1 inhibitors improved clinical outcomes in alopecia areata patients by reducing immune responses and enhancing hair keratin expression, with stronger effects in those with shorter disease duration.

This study constructed a model using serum levels of BMP2, CD8A, PRF1, and XCL1 as a non-invasive biomarker to accurately predict recurrence in patients with alopecia areata.

This study found that blocking autophagy in Atg7-deficient mouse hair keratinocytes altered the molecular composition of hair shafts by increasing the abundance of proteins involved in protein turnover while keratins remained unchanged, highlighting autophagy's role in reducing non-cytoskeletal protein concentrations in hair.

This study described a method using sodium dodecanoate and high levels of reductant to process hair shaft proteomes, allowing analysis of genetic, developmental, and forensic information beneficial to various scientific fields.

This study identified changes in immune activation, ferroptosis, and structural genes in alopecia areata subtypes, suggesting molecular markers that might help understand disease variability and guide future treatments.

BrdU speeds up hair follicle aging and reduces hair quality.

In this study, researchers using a UVB-induced mouse model identified the gene COL7A1 as a novel marker for hair luster, finding that minoxidil, caffeine, and biotin effectively restored its expression, indicating potential therapeutic strategies.

This study investigated the genetic factors influencing cashmere quality differences between Jiangnan cashmere goats and Changthangi pashmina goats, identifying 4,942 differentially expressed genes and highlighting 24 key genes related to hair follicle development and cashmere fiber formation.

This study analyzed proteomic changes in Jiangnan cashmere goats' secondary hair follicles and found that the PLIN2 gene significantly impacts hair follicle growth cycles by affecting dermal papilla cell proliferation, offering insights into breeding strategies to enhance cashmere yield.

In this review, researchers examined the molecular diversity and expression patterns of major skin appendage proteins, like keratins and EDC proteins, in tetrapods, highlighting recent findings in reptiles and birds and identifying knowledge gaps for future research.

In this case series, low-dose oral metformin was associated with improvements in symptoms and gene expression changes in Black female patients with treatment-resistant central centrifugal cicatricial alopecia, suggesting a potential therapeutic role for metformin in managing this condition.

Brepocitinib improves cicatricial alopecia and reduces key immune markers.

This study found that hair membrane fluidity is low in the cuticle but high in the cortex and medulla, with treatments like ionic surfactants and oleic acid increasing fluidity in hydrated hair; however, dehydration significantly reduces fluidity throughout the hair.

In this study, researchers analyzed the skin proteome of Alpine Merino sheep to identify proteins and pathways related to wool fiber diameter, finding that cyclic adenosine monophosphate and certain signaling pathways may play a role in this trait.

This study found that tannin improved symptoms of contact dermatitis in mice and may have positively influenced hair-related gene expression related to hair growth impediments caused by dermatitis.

This study found that hepatic KRT79 expression is regulated by PPARA and is significantly associated with liver stress, suggesting it may serve as a diagnostic marker for liver diseases.

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 identified a new heterozygous missense variant in CST6 associated with autosomal dominant keratosis follicularis spinulosa decalvans in an Austrian family, affecting epidermal differentiation and hair formation.

This study sequenced a related gene to KRT2.9 called KRT2.13, which encodes a type II keratin protein not expressed in the hair follicle, and found significant sequence homology suggesting possible gene conversion or conservation of functional sequences.
