Multifaceted Role of Keratins in Epithelial Cell Differentiation and Transformation

This review summarizes research on the synthesis and gene regulation of keratin in hair follicles, noting that coordinated gene activity is essential for hair follicle differentiation and normal hair growth, with gene clusters suggesting possible global regulatory domains.

In this study, researchers found that contrary to expectations, keratin 10 domains did not reduce cell proliferation and instead increased tumor development in genetically modified mice.

This study found that transgenic mice expressing human keratin K8 in the epidermis showed increased progression of skin lesions toward malignancy, suggesting a role for K8 in the development of invasive skin cancer.

This study found that in mice, deleting the keratin 10 gene enhances sebocyte differentiation and increases secretion of sebum and certain lipids without affecting proliferation-associated keratins.

Keratin filaments are crucial for cell structure and protection, with ongoing discoveries about their genes and functions.

This study found that ectopic expression of the lymphoid-enhancer factor can induce K17 protein in the skin, suggesting a link between skin development and wound repair processes in mice.

In a transgenic mouse model, this study found that overexpression of keratin 16 in skin keratinocytes led to hyperkeratosis and increased EGF receptor signaling, altering skin cell behavior and structure.
