A flood of new knowledge and discoveries in the basic science of keratins and keratinization has appeared in the past several years. This review summarizes this recent information with a focus on the epithelial keratin polypeptides, keratin intermediate filaments, keratohyaline granule proteins, cell envelope formation and cell envelope proteins, "soft"

Keratins, as a group of insoluble and filament-forming proteins, mainly exist in certain epithelial cells of vertebrates. Keratinous materials are made up of cells filled with keratins, while they are the toughest biological materials such as the human hair, wool and horns of mammals and feathers, claws, and beaks of birds and reptiles which usually ...

FOR the purposes of another investigation, it has been found necessary to devise a method of iodinating the tyrosine side-chains of keratin exclusively and completely. With aqueous solutions of iodine (0.1 N), no more than 75 per cent of the tyrosine of wool was iodinated under the best conditions used (64 hr. at 22.2° C. and pH 9).

The keratins and their disorders
American Journal of Medical Genetics Part C: Seminars in Medical Genetics, 2004AbstractDiseases caused by mutations in gene encoding keratin intermediate filaments (IF) are characterized by a loss of structural integrity in the cells expressing those keratins in vivo. This is manifested as cell fragility, compensatory epidermal hyperkeratosis, and keratin filament aggregation in some affected tissues.

The workshop on keratin and keratinization began with a brief discussion of keratinocyte structure observed using recently advanced technical tools for ultrastructural investigations. Hiroyuki Suzuki (Japan) discussed desmosomes analyzed with ultrathin frozen sections prepared without the use of high temperature, organic solvents and epoxy embedding ...

At first blush this book should appeal exclusively to the dermatologist and to the biologist who delights in refractory problems of insoluble proteins. Only the subtitle, An Essay in Molecular Biology , hints that the monograph is a considered review of advances in subcellular physiology focused on a single class of substances and written with the ...

The recent discovery that epidermal fragility syndromes can be caused by mutations in the genes for keratin intermediate filaments has been a turning point for research into these structural proteins. Clustering of pathogenic mutations implies differential structural sensitivity along the keratin molecule, and implications for filament function require

A method to decrease subjectivity in assessing hyperkeratosis by application of quantitative measurements is proposed. The proportion of the depth of the stratum corneum to that of the total epidermis was measured on stained sections of tissue and termed the keratinization index (K.I.). Determinations showed that the K.I. varied with anatomical regions

The effect of vitamin A on epidermal dynamics is complicated by many variables, including species and regional differences, which render compilation of meaningful data difficult. Available evidence indicates that vitamin A has a predominantly proliferative effect on mature rodent and human epidermis, which may be dose-dependent.
