Keratin 19 in the adult human prostate: tissue and cell culture studies

Cell and Tissue Research, 1996
Keratin 19 is found primarily in simple epithelia. In mammary epithelia, keratin 19 was localized to a subset of luminal cells, suggesting that keratin 19-negative cells may be the proliferative compartment of the secretory cell lineage. The structural and functional similarities of prostate and breast led us to examine keratin 19 expression in the ...

The mouse keratin 19-encoding gene: sequence, structure and chromosomal assignment

Gene, 1990
Keratin 19 (K19) is synthesized mainly in embryonic and adult simple epithelia, but has also been found in stratified epithelia as well. K19 is the smallest known keratin and is remarkable in that, contrary to all other keratins, it does not have a designated partner for the formation of filaments, implying that regulation of its expression is ...

Keratin 19-like immunoreactivity in receptor cells of mammalian taste buds

Chemical Senses, 1994
Three monoclonal antibodies, 4.62, LP2K and 170.2.14, were used to evaluate keratin 19-like immunoreactivity in gustatory epithelia. Keratin 19-like immunoreactivity was restricted to the intragemmal cells for all types of mammalian taste buds examined.

Immunohistochemical expression of keratins 8 and 19 in odontogenic cysts and tumors

Journal of Cranio-Maxillary Diseases, 2015
Objective: Cytokeratins (CKs) are integral components in the formation of enamel, dentin and/or cemental matrix and their subsequent mineralization. K8 and K19 are known to be chemically homologous during the formation of tooth structures. This feature is rather unique and is expressed across the milieu of odontogenic tissues in the physiological and ...

Unexpected Low Bone Mass Induced by Global Deletion of Keratin 18 But Not Keratin 19 in Mice

Physiology
Work from our lab has investigated the role of the cytoskeleton in osteoblasts and osteocytes. Our prior work has shown a role for a subset of post-translationally modified tubulin in the osteocyte response to mechanical stimuli and an unexpected role for the type IV intermediate

Keratin 14 protein in cultured nonparenchymal rat hepatic epithelial cells: Characterization of keratin 14 and keratin 19 as antigens for the commonly used mouse monoclonal antibody OV‐6

Molecular Carcinogenesis, 1993
AbstractWe have recently reported that cell lines of nonparenchymal origin isolated from rat liver and pancreas, which have been suggested to be the progeny of a facultative stem cell compartment in vivo, express an unusual combination of keratins (K).

Identification of Epithelial Stem Cells In Vivo and In Vitro Using Keratin 19 and BrdU

2009
Progress in the identification of skin stem cells and the improvement of culture methods open the possibility to use stem cells in regenerative medicine. Based on their quiescent nature, the development of label retention assays allowed the localization of skin stem cells in the bulge region of the pilosebaceous units and in the bottom of rete ridges ...

The keratin 19 promoter is potent for cell-specific targeting of genes in transgenic mice

Gastroenterology, 2001
Keratins are intermediate filaments that are critical in cytoskeletal organization. Their roles in cellular processes are underscored by inherited human diseases in which germline mutations of keratins are found, as well as by transgenic and knockout mouse models that recapitulate those diseases.

Absence of keratin 19 in mice causes skeletal myopathy with mitochondrial and sarcolemmal reorganization

Journal of Cell Science, 2007
Intermediate filaments, composed of desmin and of keratins, play important roles in linking contractile elements to each other and to the sarcolemma in striated muscle. We examined the contractile properties and morphology of fast-twitch skeletal muscle from mice lacking keratin 19.

Retinoic acid mediates post-transcriptional regulation of keratin 19 mrna levels

Journal of Cell Science, 1993
ABSTRACT Stratified squamous epithelia have been shown to preferentially express a site-specific pattern of keratin intermediate filaments. Retinoic acid (RA) is known to modulate expression of the basal cell keratins K19 and K5. Expression of these genes is dependent on extracellular RA concentration.
