Genomic Organization and Amplification of the Human Keratin 15 and Keratin 19 Genes

Biochemical and Biophysical Research Communications, 2000
Keratin intermediate filaments are the major components of the cytoskeleton in epithelial cells. Mutations in keratin genes have been documented in many disorders of the skin, nails, hair, and mucous membranes. Although no mutations have been described in either keratin 15 or keratin 19, they are good candidates for other as yet uncharacterized genetic

Medullary carcinoma of the breast: a tumour lacking keratin 19

Histopathology, 1994
The presence of keratin 19 (K19) was searched for by immunostaining in 16 medullary carcinomas, comprising 12 typical and four atypical cases, in 29 undifferentiated high‐grade carcinomas (NOS‐HG) with conspicuous lymphoid response and in 12 well differentiated low‐grade carcinomas (NOS‐LG).

Patterns of keratins 8, 18 and 19 during gonadal differentiation in the mouse: sex- and time-dependent expression of keratin 19

Differentiation, 1998
The acidic keratins K18 and K19 have been shown to display a sex-specific expression during gonadal differentiation in the rat. To extend these findings, we have undertaken a study of the expression of genes encoding for K18 and K19 and their basic partner K8 in the mouse from 10.5 days of gestation until adulthood, using immunofluorescence, in situ ...

Keratin 19 as a Stem Cell Marker In Vivo and In Vitro

2004
The skin is a dynamic tissue in which terminally differentiated keratinocytes are replaced by the proliferation of new epithelial cells that will undergo differentiation. The rapid and continual turnover of skin throughout life depends on a cell population with unique characteristics: the stem cells.

Keratin 19 expression in the adult and developing human mammary gland

The Histochemical Journal, 1990
In the adult human mammary gland, most of the luminal epithelial cells express keratin 19 (K19+). However, in some small ducts and terminal ductal lobular units where branching would be expected to occur during pregnancy, the pattern of expression of this keratin is heterogeneous.

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.
