This study found that Fos protein expression is closely linked to epithelial cell differentiation, particularly during cornification and cell death, with overexpression observed in keratinization-blocked mutant epidermis.

In this study, in vitro growth of human hair follicles did not alter hair keratin expression patterns, maintaining follicle integrity and proper keratinization similar to in vivo conditions.

This review discusses isotretinoin's effectiveness against severe acne vulgaris and its associated side effects, including teratogenicity and hair loss, but it reports no new experimental results.

The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This article discusses loose anagen syndrome, highlighting its characteristics, diagnostic methods, and spontaneous improvement over time, but provides no new clinical results.

This study found that 5α–reductase activity is higher in infrainfundibular keratinocytes compared to interfollicular epidermal keratinocytes, suggesting a potential role in acne-related follicular changes.

This study found that distinct glycoconjugate expression patterns in human hair follicle cells suggest complex carbohydrate metabolism, revealing a unique sugar moiety in outer root sheath cells not present in other keratinocytes.

This study suggests that spiny keratoderma may be an ectopic hair formation on palms and soles, based on keratinization patterns observed using antikeratin antibodies and electron microscopy.

This study examined the expression patterns of various cytokeratins in the outer root sheath of human anagen hair follicles, noting distinct differentiation patterns and localization of keratin markers.

This study observed that the keratinization pattern of trichilemmal cysts in two Japanese women may originate from the proliferation of the outer root sheath in the follicular isthmus of anagen hairs.

This study found that VEGF-deficient keratinocytes can form tumors using different aneuploidy and signaling patterns, highlighting VEGF's role beyond angiogenesis in tumor cell growth and survival.

This study found that different types of seborrheic keratosis demonstrate diverse differentiation patterns, highlighting its undifferentiated and hyperproliferative state with varying keratinization directions.

This study investigated the immunohistochemical characteristics of keratin proteins in epidermal appendages, finding variable staining patterns in different skin structures and tumor cells, which suggests differences in keratinization.

This case report describes an 8 cm giant pilomatricoma on a 67-year-old man's scalp, revealing distinct transcriptional patterns related to hair follicle factors and keratin through spatial gene expression analysis.

Norfolk Terriers have a genetic skin defect causing scaling and blisters due to a keratin issue.

This review discusses the structure, types, and distribution of keratins and their role in tissue fragility disorders, particularly within the oral cavity, without presenting new clinical findings.

This study found that the Meibomian gland shares structural and cytokeratin composition similarities with hair follicles, and plays a role in hyper-keratinisation observed in obstructive Meibomian gland dysfunction.

This study explored proteomics to investigate protein changes during protein synthesis and keratinization in maturing wool fiber, but the relationship to fibre development remains largely unknown.

In this study, researchers observed that spontaneously mutated mice with a hair loss phenotype exhibited significant differential expression of genes related to keratinization and hair follicle formation, suggesting these mice could model human alopecia for future research and treatment development.

Cortisone may help hair regrow by altering the local environment, with regrowth starting 3-4 weeks after treatment, but its use is not widely recommended.
