This study suggests that the C-terminal of AHF is crucial for its binding to keratin bundles and modulating the keratin meshwork in hair follicles.

A new EDA gene mutation was found in a Chinese family with a specific skin disorder.

This study found that loss of Ptch1 function in mouse skin's basal cells is sufficient to rapidly induce tumors resembling human basal cell carcinoma, suggesting Ptch1 as a key tumor suppressor.

This study used developing mouse hair follicles to explore early epithelial bud formation, finding that the Rho GTPase regulator ARHGEF3 plays a crucial role in regulating cell fate and cadherin patterning, with knockouts showing disrupted morphology and increased straight hair follicle growth.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

Hair shaft malformation contributes to Central Centrifugal Cicatricial Alopecia.

This study reports a case of a child with congenital skin fragility, alopecia, and cardiomyopathy due to compound heterozygous mutations in the DSP gene causing desmoplakin deficiency.

This study identified a heterozygous de novo mutation in the ODC1 gene causing a new disorder characterized by overgrowth and developmental delay, and suggests that DFMO treatment may help manage elevated ODC activity and putrescine levels.

This study demonstrated that HOXC13 directly influences hair keratin gene expression by binding to specific DNA motifs, suggesting its role in early hair follicle differentiation.

This study found that overexpressing CRABP1 in dermal papilla cells promotes their proliferation and influences key genes in the Wnt/β-catenin signaling pathway, which may offer insights into mechanisms controlling hair follicle development.

hHb1, hHb3, and hHb6 mRNAs start expressing at the same time in hair follicles.

The researchers reported that disrupting ATRA signaling by deleting RDHE genes in the hair follicle led to altered hair follicle cycles, composition, and gene expression, indicating RDHEs' role in hair follicle signaling coordination.

This study revealed that Patched receptors establish a Hedgehog signaling gradient in developing hair follicles, which may influence their formation and potentially offer a diagnostic tool for distinguishing Hedgehog-driven tumors.

This study demonstrated that mitochondrial function in keratinocytes is crucial for maintaining skin homeostasis and hair follicle development, as its impairment led to disrupted hair morphogenesis and early death in mice.

This case study reported a neonate of Indian descent with localized hypotrichosis type 1 due to a likely pathogenic deletion in the DSG4 gene, marking the first such case from India.

This study found that inhibiting the enzyme ornithine decarboxylase (ODC) prevented UVB-induced basal cell carcinomas in a mouse model, suggesting ODC is a potential target for chemoprevention strategies.

Deleting Crif1 in mouse skin disrupts skin balance and hair growth.

This study concluded that CNGC14 is a calcium-permeable channel crucial for polarized tip growth in Arabidopsis root hairs, but other channels may also influence the observed calcium influx.

In this study, researchers identified CENPV as a new CYLD interacting partner that localizes to primary cilia and regulates acetylated tubulin levels, offering insights into the pathogenesis of skin appendage tumors.

This study found that Arabidopsis thaliana mutants with altered AtRBOHC/RHD2 enzyme function showed abnormal protein regulation linked to increased drought sensitivity due to disrupted plasma membrane protein balance and cytoskeleton changes, as revealed through proteomic analysis and advanced microscopy.

This study found that the activity of CD73, an enzyme expressed in the hair follicle epithelium, may regulate human hair growth by modulating adenosine production.
