This review discusses the formation and structure of the cornified cell envelope in the epidermis, highlighting biochemical pathways and genetic factors, but presents no new experimental results.

Feathers become harder as they develop due to a change in keratin type.

This study found that CTCF is crucial for proper skin and hair follicle development in mice, affecting keratinocyte differentiation and gene expression in keratin loci.

This study found that the unique crest feather formation in Polish chickens is driven by a 195-bp duplication in the HoxC10 gene region, which alters gene expression by modifying the genomic structure, suggesting a mechanism for diverse integumentary appendages in birds.

In this study, forced expression of the transcription factor cDermo-1 in chicken dermis led to the formation of ectopic feather buds and enhanced feather growth, demonstrating its role in initiating skin appendage development.

This study suggests that the CXCL8 gene may regulate cashmere fineness in Liaoning cashmere goats, providing new insights into the cellular mechanisms of cashmere growth and quality.

In this study, Msx2-deficient mice showed progressive hair loss due to shortened anagen phase and prolonged catagen and telogen phases, resulting in cyclic alopecia with structurally abnormal hair shafts.

This study found that mice deficient in the enzyme cathepsin L exhibited impaired degradation of autophagolysosomal content, leading to an accumulation of large, abnormal vesicles in various tissues.

In this study, researchers found that the cornification process in the nuptial pads of Xenopus frogs involves the expression of the type II hair keratin homolog, krt59, and is regulated by the transcription factor hoxc13, showing similarities to mammalian hair evolution.

This review discusses the structure and assembly of the cornified cell envelope in stratified squamous epithelial cells and various disorders leading to barrier defects, but reports no new findings.

This study provides evidence that ILC1-like cells can induce alopecia areata in previously healthy human hair follicles, challenging the view that it is solely an autoantigen-dependent autoimmune disease.

This study reported that CXCL12 may have a dual role in alopecia areata, where decreased levels could impair angiogenesis and disrupt vascular support to hair follicles, while its overexpression might exacerbate autoimmune attacks on hair follicles, contributing to hair loss.

This study found that Cathepsin E plays a crucial role in keratinocyte terminal differentiation, affecting epidermis formation and homeostasis in mice.

This study introduced ElixirSeeker2, a computational framework for designing anti-aging peptides, and found that some newly identified peptides significantly delayed cellular senescence and enhanced cellular and locomotor functions in aged Caenorhabditis elegans.

This study found that a specific mutation in the mouse RXRalpha gene significantly impacts immune responses and causes hair loss and skin cysts.

In this study, researchers analyzed skin tumors from patients with CYLD cutaneous syndrome and found that loss of CYLD function is linked to changes in cellular signaling pathways, particularly NF-κB signaling, and leads to increased secretion of specific extracellular matrix proteins.

This study found that misexpression of Hoxc8 in mice led to ectopic mammary development and suggests Hox genes may play crucial roles in the regional specification and initiation of cutaneous accessory organs.

A woman developed a severe skin reaction called toxic epidermal necrolysis after taking the antibiotic cephalexin.

This study found that CNGC 6, CNGC 9, and CNGC 14 are crucial for maintaining calcium oscillations necessary for normal root hair growth in plants, with mutations leading to defects like swelling and bursting.

In this study, inducible whole-body Acly-knockout mice revealed that ACLY is essential for skin homeostasis, as its deficiency led to increased sebum production and skin abnormalities, indicating a vital role for cytosolic acetyl-CoA synthesis in preserving skin barrier integrity and systemic lipid regulation.

This study found that the co-ablation of C/EBPalpha and C/EBPbeta in adult mouse skin disrupted sebocyte differentiation and epidermal homeostasis, highlighting their critical roles in these processes.

This review discusses the role of the CXXC5 protein as a transcription factor and signaling coordinator, noting its involvement in embryonic development, tissue homeostasis, and diseases such as tumorigenesis, but reports no new experimental findings.

This study identified Sciellin, a new protein precursor to the cornified envelope in keratinocytes, with unique solubility properties hinting at its potential role in envelope assembly.

This study found that cepharanthine and its structural analogues may stimulate hair growth by promoting the proliferation of human dermal papilla cells and increasing VEGF expression in vitro.

This study demonstrated that switching aE-catenin to aT-catenin in murine skin substantially rescued hyperproliferative and pre-cancerous conditions, but led to partial baldness, indicating potential functional discrepancies.

In this study, researchers identified loss of function variants in the HR gene as likely causes of the distinct roaning hair coat seen in lykoi cats.

Krox20 is important for cell differentiation in the brain and hair follicles.

This study concluded that dilated cardiomyopathy in Ctsl-deficient mice is mainly due to the lack of cathepsin L in cardiomyocytes, with additional heart stress from the fur defect.

In this mouse study, the absence of the Ascl4 gene did not affect the development of hair follicles, teeth, or mammary glands, suggesting it is non-essential for these processes.

This study found that Hoxc13 gene expression, influenced by melatonin, was associated with hair follicle activity in Cashmere goats, with in vitro evidence suggesting effects on genes relevant to follicle development.
