Keratins in Invertebrates [PDF]
Nature, 1950 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 ...

THE STRUCTURE OF ALPHA KERATIN [PDF]
Proceedings of the National Academy of Sciences, 1957 Known structural principles (close packing, maximum hydrogen bonding, the tendency of like groups to be surrounded in like manner, and the approximate constancy of interatomic distances and bond angles) are used, with meridional and equatorial x-ray data, to deduce and check the structure pattern for alpha-keratin.

Keratins 6, 16, and 17 in Health and Disease: A Summary of Recent Findings. [PDF]
Curr Issues Mol BiolKeratins 6, 16, and 17 occupy unique positions within the keratin family. These proteins are not commonly found in the healthy, intact epidermis, but their expression increases in response to damage, inflammation, and hereditary skin conditions, as well ...

Journal of Investigative Dermatology, 1976 Early studies have already shown that the tonofibrils of malpighian cells consist of a --SH containing fibrous alpha-protein. It was assumed that the highly resistant protective substance, keratin, was formed by the conversion of --SH groups into --S--S--bonds in this protein.

Squamous Cell Differentiation in Metastatic Papillary Thyroid Carcinoma: Metaplastic [PDF]
Iranian Journal of Pathology, 2018 Squamous cell differentiation (SCD) may occur in papillary thyroid carcinoma (PTC) only at metastatic sites. We have studied cytokeratin CK5/6 and P63 along with TTF1 (thyroid transcription factor 1) and B-Raf (V-Raf murine sarcoma viral oncogene ...

The comparative analysis of the methods for keratin extraction from sheep wool and human hair
Біологія тварин, 2020 Nowadays, biopolymers such as keratins are widely used in biomedicine due to their low toxicity, biocompatibility, and biodegradability. At the molecular level, keratins differ from other structural proteins by a high content of disulfide bonds, which ...

Keratin 17 Suppresses Cell Proliferation and Epithelial-Mesenchymal Transition in Pancreatic Cancer
Frontiers in Medicine, 2020 Keratin 17 (K17), a member of type I acidic epithelial keratin family, has been reported to be upregulated in many malignant tumors and to be involved in promoting the development of tumors.
