More Antibodies against Keratin 19 Interaction Partners

Human Keratin 19 (KRT19) interaction partners

  1. The combined use of CK19 and CD56 (show NCAM1 Antibodies) is helpful in discriminating papillary thyroid carcinoma and its variants from other mimicking thyroid lesions.

  2. YAP1 (show YAP1 Antibodies) activation was more commonly found in CCAs than in pure HCCs (show HCCS Antibodies). However, a differing pattern of YAP1 (show YAP1 Antibodies) expression between cHC (show CLTC Antibodies)-CCAs and CK19(+) HCCs (show HCCS Antibodies) and the poor prognosis of YAP1 (show YAP1 Antibodies) positive hepatic carcinomas suggests that YAP1 (show YAP1 Antibodies) may have a preferential role in aggressive tumor behavior, rather than in the determination of cellular lineage in hepatic carcinomas

  3. Circulating tumor cells expressing cytokeratin and tumor-initiating cell markers, including ALDH, CD133, and CD44, were identified in patients with pancreatic adenocarcinoma. These TIC-like CTCs were associated with poor prognosis after surgical resection and with an increased incidence of tumor recurrence

  4. Aberrant decreased miR (show MLXIP Antibodies)-26a could promote cell proliferation by regulating KRT19 which plays important role in the pathogenesis of cholangiocarcinoma.

  5. The detection of TK1 (show TK1 Antibodies) combined with that of cytokeratin-19 fragment (CYFRA21-1), CEA (show CEACAM5 Antibodies) or NSE (show ENO2 Antibodies) increased the diagnostic value of TK1 (show TK1 Antibodies) for lung squamous cell carcinoma, adenocarcinoma and small cell lung cancer, respectively.

  6. Our results are of special importance against the background that CK19 positive carcinomas revealed a significantly poorer prognosis and therefore emphasize its prognostic and possible diagnostic role in tongue cancer.

  7. (18)F-FDG (show SMUG1 Antibodies)-PET can be used to predict K19 expression in hepatocellular carcinoma and should thereby aid in the development of novel therapeutic strategies targeting K19(+) hepatocellular carcinoma cancer stem cells

  8. Immunohistochemical assessment of both CK19 and SCCAg status in histologically negative sentinel lymph nodes may be a valuable approach for predicting recurrence and survival after curative surgery for cervical squamous cell carcinoma.

  9. Positive CK-19 expression can be used as a predictor of poor prognosis of PNET

  10. Data suggest that high cytokeratin 19 (CK19) levels in peripheral blood may independently predict non-sentinel lymph node (nSLN) metastasis in breast cancer patients.

Mouse (Murine) Keratin 19 (KRT19) interaction partners

  1. Cytokeratin-19 (CK-19)+ specific deletion of tumor suppressors p53 (show TP53 Antibodies) and Retinoblastoma (Rb) indicated that carcinomas at the injury site originates from cholangiocytes or liver progenitor cells.

  2. Demonstrate that K19 plays an important role in the ductular reaction that constitutes the basic regenerative response to chronic liver injury.

  3. Branched desmin (show DES Antibodies)-deficient (DKO) myofibers show significantly faster rates of calcium ion (Ca2 (show CA2 Antibodies)+) clearance, with milder branching phenotype observed in DKO muscle suggesting that absence of keratin-19 corrects the defect created by absence of desmin (show DES Antibodies) alone.

  4. the structural response of each genotype is distinct, suggesting multiple mechanisms by which desmin and keratin influence the biomechanical properties of myofibers

  5. The expression of CK19 and EGFR (show EGFR Antibodies) in lymphatic metastasis of laryngeal carcinoma was higher than in controls.

  6. Results suggest that keratin filaments containing K19- and desmin (show DES Antibodies)-based intermediate filaments can play independent, complementary, or antagonistic roles in the physiology and morphology of fast-twitch skeletal muscle.

  7. a dual mechanism of how PDX-1 (show PDX1 Antibodies) negatively regulates Krt19 ductal specific gene expression

  8. expression of nestin (show NES Antibodies) and cytokeratin 19 is a normal property of embryonic stem cells preceding differentiation into C-peptide/insulin (show INS Antibodies)-producing cells without any selection for nestin (show NES Antibodies)-positive phenotypes

  9. loss of the keratin cytoskeleton causes defects in the trophoblast giant cell layer

  10. transduction of PDX1 (show PDX1 Antibodies) in primary pancreatic ductal cells suppresses K19 expression, and short interfering RNA to PDX1 (show PDX1 Antibodies) in Min6 insulinoma (show RPS15 Antibodies) cells and results in the induction of normally undetectable K19

Keratin 19 (KRT19) Antigen Profile

Protein Summary

The protein encoded by this gene is a member of the keratin family. The keratins are intermediate filament proteins responsible for the structural integrity of epithelial cells and are subdivided into cytokeratins and hair keratins. The type I cytokeratins consist of acidic proteins which are arranged in pairs of heterotypic keratin chains. Unlike its related family members, this smallest known acidic cytokeratin is not paired with a basic cytokeratin in epithelial cells. It is specifically expressed in the periderm, the transiently superficial layer that envelopes the developing epidermis. The type I cytokeratins are clustered in a region of chromosome 17q12-q21.
