CK1 family members share a highly conserved kinase domain but differ in their variable N- and C-terminal domains. TBB is a highly selective, ATP/GTP-competitive inhibitor of casein kinase-2 (CK2)with IC50s of 0.9 and 1.6 μM for rat liver and human recombinant CK2 respectively). De-regulation of CK2 has been linked to tumorigenesis as a potential protection mechanism for mutated cells. [2] It is worth noting that other β isoforms have been found in other organisms but not in humans. 10 µM QUE was used as a positive control. Acts in an ATP/GTP competitive manner. Figure 1. As well the anti-apoptotic function of CK2 allows the cancerous cell to escapes cell death and continue proliferating. Background: Casein kinase 2 (CK2) is a Ser/Thr protein kinase that coregulates a great number of signalling pathways in the cell. Cell Assay Various cell lines are seeded at a density of 3,000 cells per well 24 hours prior to treatment, in appropriate media, and then treated with indicated concentrations of Silmitasertib (CX-4945). (A,B) Western blot analysis showed that the expression of CK2α and CK2β proteins was upregulated compared with NHost normal human osteoblasts and UBE6T15 immortalized human mesenchymal stem cells.

After incubation for 2 d, reporter gene activity is measured using the Bright-Glo luciferase assay system. As well the anti-apoptotic function of CK2 allows the cancerous cell to escapes cell death and continue proliferating. 218696 ; The Casein Kinase I Inhibitor, D4476, also referenced under CAS 301836-43-1, controls the biological activity of Casein Kinase I. Title:CX-4945, a Selective Inhibitor of Casein Kinase 2, Synergizes with B Cell Receptor Signaling Inhibitors in Inducing Diffuse Large B Cell Lymphoma Cell Death VOLUME: 18 ISSUE: 6 Author(s):Elisa Mandato, Sara Canovas Nunes, Fortunato Zaffino, Alessandro Casellato, Paolo Macaccaro, Laura Quotti Tubi, Andrea Visentin, Livio Trentin, Gianpietro Semenzato and Francesco Piazza* These findings suggest that CX-4945 elicits an anti-Warburg effects in gastric cancer overexpressing Tap73 and inhibits gastric tumorigenesis. Casein kinase 2 (EC 2.7.11.1)(CK2/CSNK2) is a serine/threonine-selective protein kinase that has been implicated in cell cycle control, DNA repair, regulation of the circadian rhythm, and other cellular processes. CK2 overexpression has been demonstrated in hematological malignancies, including chronic lymphocytic leukemia, chronic myeloid leukemia, acute lymphoblastic leukemia, acute myeloid leukemia, and multiple myeloma. In these same cells, the CK2 inhibitor silmitasertib displayed potent antiviral activity. Casein kinase II (CK2) is involved in multiple tumor-relevant signaling pathways affecting proliferation and apoptosis. [6], Among the array of substrates that can be altered by CK2 many of them have been found in increased prevalence in cancers of the breast, lung, colon, and prostate. De-regulation of CK2 has been linked to tumorigenesis as a potential protection mechanism for mutated cells. TTP22 is a casein kinase 2 (CK2) inhibitor with an IC50 value of 100 nM. TAp73, a structural homolog of the tumor suppressor p53, acts as a critical regulator of the Warburg effect. 2,3,7,8-Tetrahydroxy[1]benzopyrano[5,4,3-cde][1]benzopyran-5,10-dione. In this study, we evaluated the efficacy of the CK2 inhibitor, CX-4945, in gastric cancer cell lines and explored the potential predictive biomarkers for CX-4945 sensitivity. Here, we investigated the relationship between casein kinase 2 (CK2), p53 and HIF-1. [1] CK2s anti-apoptotic function is in the continuation of the cell cycle; from G1 to S phase and G2 to M phase checkpoints. Longdaysin is a Casein Kinase inhibitor with IC50 values of 8.8 μM, 5.6 μM, 52 μM and 29 μM for CKIδ, CKIα, ERK2 and CDK7. Lysophosphatidylcholine selectively activated p42/p44 mitogen-activated protein kinase. Chemical name. Casein Kinase 2 Inhibitors. When added with other potent anti-cancer therapies, a CK2 inhibitor may increase the effectiveness of the other therapy by allowing drug-induced apoptosis to occur at a normal rate. [3] An increased concentration of substrates in cancerous cells infers a likely survival benefit to the cell, and activation of many of these substrates requires CK2. The casein kinase 2 (CK2) protein kinase is a pro-survival kinase and therapeutic target in treatment of various human cancers. The casein kinase 2 (CK2) protein kinase is a pro-survival kinase and therapeutic target in treatment of various human cancers. Phase 1/2. This led to the identification of clomiphene as a candidate. 2015 Mar 31;6:70. The Casein Kinase II Inhibitor I, also referenced under CAS 17374-26-4, controls the biological activity of Casein Kinase II. Like CK1, casein kinase 2 (CK2) does not seem to be regulated by any second messenger molecule, but by a number of compounds with putative physiological importance (Allende and Allende, 1995). MSDS (material safety data sheet) or SDS, CoA and CoQ, dossiers, brochures and other available documents. The inhibition of CK2 using CX-4945 elicits an anti-Warburg effect through the downregulation of TAp73. TTP22 is a casein kinase 2 (CK2) inhibitor with an IC50 value of 100 nM. This IL-1beta-induced phosphorylation of p65 was specifically prevented by pretreatment of EMT-6J cells with the casein kinase II inhibitor DRB. CK1 isoforms are involved in Wnt signaling, circadian rhythms, nucleo-cytoplasmic shuttling of transcription factors, DNA repair, and DNA transcription. Purity > 98% CAS Number. Recently, using different virtual screening approaches, we have identified several novel CK2 inhibitors. 1694 . Chemical structure. Although the targets of CK2 are predominantly nucleus-based the protein itself is localized to both the nucleus and cytoplasm. Cat. Casein kinase 2 (CK2) is an ubiquitous, essential, and highly pleiotropic protein kinase whose abnormally high constitutive activity is suspected to underlie its pathogenic potential in neoplasia and other diseases. - Find MSDS or SDS, a COA, data sheets and more information. Casein Kinase 2 Inhibitor, CX-4945, as a Potential Targeted Anticancer Agent in Gastric Cancer In this study, CX-4945 showed modest antitumor efficacy in gastric cancer cell lines. The role of myeloid cells as regulators of tumor progression that significantly impact the efficacy of cancer immunotherapies makes them an attractive target for inhibition. The Casein kinase 1 family (EC 2.7.11.1) of protein kinases are serine/threonine-selective enzymes that function as regulators of signal transduction pathways in most eukaryotic cell types. Exhibits a multitude of biological activities including antioxidant, antiproliferative and pro-apoptotic activity. Molecular weight. Casein kinase 2 catalyzed protein serine/threonine phosphatase 2A phosphorylation thereby inhibiting its activity. Here we explore the effect of a novel, potent, and selective inhibitor of serine/threonine protein kinase casein kinase 2 (CK2) on modulating myeloid cells in the tumor microenvironment. Because the inhibition of casein kinase 2 (CK2) has been reported as a novel therapeutic strategy for many cancers, we investigated the effects of CK2 inhibitors in pancreatic cancer cell lines. [3] A functional difference between α and α’ has been found but the exact nature of differences isn’t fully understood yet. Recently, it was reported that DNA methylation patterns are regulated by casein kinase 2 (CK2) mediated phosphorylation of DNMT3a. Casein Kinase 2 Inhibitors: Products Casein kinases are a group of ubiquitous Ser/Thr kinases that phosphorylate key regulatory proteins involved in the control of cell differentiation, proliferation, chromosome segregation, circadian rhythms, and metabolic pathways. CK1 isoforms are involved in Wnt signaling, circadian rhythms, nucleo-cytoplasmic shuttling of transcription factors, DNA repair, and DNA transcription. This small molecule/inhibitor is primarily used for Phosphorylation & Dephosphorylation applications. TTP 22 is a high affinity, casein kinase 2 (CK2) inhibitor (IC50= 0.1uM, Ki= 40nM).
