Similarities in DSG1 and KRT3 Downregulation through Retinoic Acid Treatment and PAX6 Knockdown Related Expression Profiles: Does PAX6 Affect RA Signaling in Limbal Epithelial Cells?

Biomolecules, 2021
Congenital PAX6-aniridia is a rare panocular disease resulting from limbal stem cell deficiency. In PAX6-aniridia, the downregulation of the retinol-metabolizing enzymes ADH7 (All-trans-retinol dehydrogenase 7) and ALDH1A1/A3 (Retinal dehydrogenase 1 ...

Tescalcin over-expression increases Keratin 18 and 19 in K562 cells

Journal of Basic and Clinical Health Sciences, 2022
Tescalcin (TESC) has been shown to be essential in mammalian cells as a regulator of intracellular Ca2+. Ca2+ is a second messenger functioning in many metabolic pathways as well as in cell differentiation, cell size and the cell cycle. K562 cells over-expressing TESC change their morphology and adopt adherent properties.

Clinical and Prognostic Significances of Cytokeratin 19 and KIT Expression in Surgically Resectable Pancreatic Neuroendocrine Tumors [PDF]

Journal of Pathology and Translational Medicine, 2015
Background: Pancreatic neuroendocrine tumors (PanNETs) are malignant endocrine neoplasms that present diverse clinical behaviors. Therefore, identification of biomarkers of PanNETs is important for stratification of the prognosis of PanNET patients ...

Expression of basal cell keratin 15 and keratin 19 in oral squamous neoplasms represents diverse pathophysiologies.

Histology and histopathology, 2012
Human epithelium contains keratin, which is expressed during differentiation. Depending on the target cell type, different types of keratin are expressed, and their alterations seem to represent changes in cell properties. The basal cells of oral epithelium express keratin 5 (K5), K14, K15 and K19, but their alterations in tumors are unclear.

Expression of keratins 8, 18, and 19 in epithelia of atrophic oral lichen planus [PDF]

European Journal of Oral Sciences, 2020
Keratins form intermediate filaments of the cytoskeleton in keratinocytes and have roles in cell structure, signaling, intracellular transport, and cell death. Oral lichen planus (OLP) is an oral inflammatory disease with derangements in basal keratinocytes and disruption of the basal membrane.

Heterogeneity of estrogen receptor expression in circulating tumor cells from metastatic breast cancer patients. [PDF]

PLoS ONE, 2013
BACKGROUND: Endocrine treatment is the most preferable systemic treatment in metastatic breast cancer patients that have had an estrogen receptor (ER) positive primary tumor or metastatic lesions, however, approximately 20% of these patients do not ...

The Developmental & Molecular Requirements for Ensuring that Human Pluripotent Stem Cell-Derived Hair Follicle Bulge Stem Cells Have Acquired Competence for Hair Follicle Generation Following Transplantation

Cell Transplantation, 2021
When using human induced pluripotent stem cells (hiPSCs) to achieve hair follicle (HF) replacement, we found it best to emulate the earliest fundamental developmental processes of gastrulation, ectodermal lineage commitment, and dermogenesis.

Keratin 19: Predicted amino acid sequence and broad tissue distribution suggest it evolved from keratinocyte keratins

Journal of Investigative Dermatology, 1989
The type I keratin 19 is unusual in its tissue distribution in that under normal circumstances it does not seem to be restricted, as the other keratins are, to expression in either stratified or simple epithelia. In addition to the previously reported distribution of keratin 19 in human tissues, we have observed keratin 19 in epidermal basal cells, in ...

Cross-talk between microRNA-let7c and transforming growth factor-β2 during epithelial-to-mesenchymal transition of retinal pigment epithelial cells [PDF]

International Journal of Ophthalmology, 2020
AIM: To explore the roles of microRNA-let7c (miR-let7c) and transforming growth factor-β2 (TGF-β2) and cellular signaling during epithelial-to-mesenchymal transition (EMT) of retinal pigment epithelial cells. METHODS: Retinal pigment epithelial (ARPE-19)
