Archives of Internal Medicine, 1964
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 ...

Current Opinion in Genetics & Development, 1994
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

Keratins are the major structural proteins of the vertebrate epidermis and its appendages, constituting up to 85% of a fully differentiated keratinocyte. Together with actin microfilaments and microtubules, keratin filaments make up the cytoskeletons of vertebrate epithelial cells.

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.

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.

Low molecular weight keratin was self-crosslinked by microbial transglutaminase (mTGase) for application to wool fabric. From amino acid determination, keratin produced by the alkaline hydrolysis of wool showed requisite glutamine and lysine required for mTGase-mediated transamidation.

IF the term ‘keratin’ were applied only to those proteins which contain a high proportion of cystine, which give a keratin-type of X-ray diffraction photograph and which dissolve with ease only in alkaline solutions of reducing agents, then keratins, so far as is known, are confined to the epidermis and epidermal appendages of vertebrates, and are ...

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 Keratin bundling proteins are a subcategory of intermediate filament associated proteins (IFAPs) that are defined by their ability to organize keratin filaments into macrofibrilar arrays; however, only filaggrin and a related protein have been shown unequivocally to bundle keratin and other intermediate filaments into parallel ...
