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.

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

The archosauria consist of two living groups, crocodilians, and birds. Here we compare the structure, expression, and phylogeny of the beta (β)-keratins in two crocodilian genomes and two avian genomes to gain a better understanding of the evolutionary ...

A LTHOUGH THE CLINICAL CHARACTERIStics of keratoacanthomas (KAs) are well known, there is limited information about their dermoscopic appearance and features. We evaluated 15 KAs and welldifferentiated squamous cell carcinomas (SCCs). Dermoscopic evaluation revealed that all lesions demonstrated a white to yellowish round structure surrounded by a ...

Publisher Summary This chapter deals with the chemistry of keratins. The chapter discusses the efforts to prepare pure keratin derivatives for composition, sequence, and end group studies and to obtain mono disperse solutions of these derivatives for physicochemical characterization.

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.

This chapter deals with the various ways in which keratin (extracted from different sources) can be processed to obtain different types of products. In the first section, solvents and polymers that must be employed tomake this natural biopolymer usable are discussed.
