Cornified Epithelial Teeth of Jawless Vertebrates Contain Proteins Similar to Keratin-Associated Proteins of Mammalian Skin Appendages [PDF]

open access: yesJournal of Developmental Biology
Keratins and keratin-associated proteins (KRTAPs) are the main components of mammalian nails and hair. Comparative genomics and gene expression studies have revealed that keratins are conserved in all vertebrates, whereas KRTAPs exist only in mammals ...

KERATINIZATION

open access: yesInternational Journal of 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.

The comparative analysis of the methods for keratin extraction from sheep wool and human hair

open access: yesБіологія 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 ...

Immunohistohemical evidences of pregnancy in uterine curettage tissue by the use of a double immunocytochemical staining technique using cytokeratin 7 and vimentin antibodies [PDF]

open access: yesVojnosanitetski Pregled, 2008
Background/Aim. Usual histopatological diagnosis of intrauterine pregnancy is made by demonstration of chorionic villi, but in the curettage tissue from intrauterine miscarriage they may not be present in all cases. The use of monoclonal antibody against

Expression of cytokeratins 5/6 and cytokeratin 17 in invasive breast carcinoma [PDF]

open access: yesVojnosanitetski Pregled, 2012
Background/Aim. Cytokeratins (CK) 5/6 and 17, myoepithelial markers, are also expressed in a proportion of breast carcinomas. Breast carcinomas expressing basal epithelium cytokeratins constitute a tumor subgroup that shows common but heterogeneous ...

A novel and ancient group of type I keratins with members in bichir, sturgeon and gar

open access: yesFrontiers in Zoology, 2007
1. Background Vertebrate epithelial cells typically express a specific set of keratins. In teleosts, keratins are also present in a variety of mesenchymal cells, which usually express vimentin.

Immunohistochemistry as a paramount tool in research of normal urothelium, bladder cancer and bladder pain syndrome

open access: yesEuropean Journal of Histochemistry, 2021
The urothelium, an epithelium of the urinary bladder, primarily functions as blood-urine permeability barrier. The urothelium has a very slow turn-over under normal conditions but is capable of extremely fast response to injury.
