  1. Patients with CK19 positivity showed a higher prevalence of microvessel invasion than those without CK19.

  2. Serum CYFRA21-1 and CEA (show CEACAM5 Proteins) can be used as prognostic factors of NSCLC patients. Combinative detection of the two indices will be more reliable.

  3. Data show that serum neuron-specific enolase (show ENO2 Proteins), cytokeratin 19 fragment 21-1, pro-gastrin-releasing peptide (show GRP Proteins), squamous cell carcinoma antigen, tissue inhibitor of metalloproteinase-1, and human epididymis protein 4 are not associated with brain metastases.

  4. CK19 expression was measured in hepatocellular carcinoma at different stages and correlated with prognosis. CK19+/GPC3 (show GPC3 Proteins)+ HCC (show FAM126A Proteins) has the highest risk of intrahepatic metastasis, microvascular invasion, regional lymph node involvement, and distant metastasis.

  5. CK19 staining was found in hepatic hydatidosis patients with and without biliary fistula.

  6. When confirmed by a low alpha-fetoprotein (show AFP Proteins) concentration (<400 mug/L), CK-19 expression in is an additional valuable indicator of early recurrence, distant metastasis, and poor prognosis in HBV-positive patients

  7. Study confirms the prognostic significance of K19 expression in Caucasian patients with hepatocellular carcinoma.

  8. K19 is a new cancer stem cell marker associated with epithelial mesechymal transformation and TGFb (show TGFB1 Proteins)/Smad (show SMAD1 Proteins) signaling.

  9. Postoperative CK19-2G2 concentration may be an indicator of prognosis. An increase after the initial drop in CK19-2G2 concentration after surgery may indicate a poor prognosis.

  10. CK19 and HBME-1 were significantly expressed more in papillary carcinoma as compared to follicular carcinoma

Mouse (Murine) Keratin 19 (KRT19) interaction partners

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

  2. Branched desmin (show DES Proteins)-deficient (DKO) myofibers show significantly faster rates of calcium ion (Ca2 (show CA2 Proteins)+) 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 Proteins) alone.

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

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

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

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

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

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

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

  10. This is the first demonstration of a mammalian phenotype associated with a genetic perturbation of keratin 19.

Keratin 19 (KRT19) Protein 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.
