Dickkopf WNT signaling pathway inhibitor 1 (Dkk1) is a protein-coding gene that acts from the anterior visceral endoderm. [6][7] The dickkopf protein encoded by DKK1 is an antagonist of the Wnt/β-catenin signalling pathway that acts by isolating the LRP6 co-receptor so that it cannot aid in activating the WNT signaling pathway.

Mar 30, 2025 · DKK1 (Dickkopf WNT Signaling Pathway Inhibitor 1) is a Protein Coding gene. Diseases associated with DKK1 include Chiari Malformation Type I and Osteoporosis, Juvenile. Among its related pathways are ncRNAs involved in Wnt signaling in hepatocellular carcinoma and Alzheimer's disease and miRNA effects.

Dickkopf-1 (Dkk1) is a secretory antagonist of the classical Wnt signaling pathway. Many studies have reported that Dkk1 is abnormally expressed in tumor cells, and abnormal expression of Dkk1 can inhibit cell proliferation or induce apoptosis ...

Clinical studies in a range of cancers have detected elevated levels of the Wnt antagonist Dickkopf-1 (DKK1) in the serum or tumors of patients, and this was frequently associated with a poor prognosis. Our analysis of DKK1 gene profile using data ...

Dickkopf-1 (DKK1) is a well-characterized Wnt inhibitor and component of the Wnt/β-catenin signaling pathway, whose dysregulation is associated with multiple abnormal pathologies including osteoporosis, Alzheimer’s disease, diabetes, and various cancers.

Feb 19, 2025 · DKK1 is a novel target gene in the response to amino acid deficiency and that the expression of DKK1 is up-regulated through an ATF4-independent and an ERK-dependent pathway.

May 13, 2024 · In in vitro experiments, both DKK1 silencing and deletion reduced cell growth and migration of both cell lines. DKK1 knockout clones (DKK1-KO) exhibited cell cycle arrest, tubulin...

Dec 12, 2019 · Our results show that Dkk1 represses cell polarization and integrity of cell-cell adhesion, independently of its impact on β-catenin protein degradation. Concurrently, Dkk1 prevents nuclear localization of β-catenin by restricting its distribution to a …

Dkk-1 is a secreted protein that contains a 31-residue N-terminal signal peptide, 2 cysteine rich domains, and a putative carboxy terminal N-glycosylation site. DKKs play an important role in vertebrate development.

Sep 1, 2007 · In this study, we examined whether Dickkopf-1 (DKK1), a protein that is not expressed in most normal tissues but is expressed by tumor cells from almost all patients with myeloma, could be a good candidate.
