We also observed differential gene expression and induced immune cell infiltration in tumors pretreated with ICG-001 and then treated with CAR T cells as compared with single treatment groups or when ICG-001 treatment was administered after CAR T cell therapy. We conclude that specific Wnt/CBP/β-catenin antagonism results in pleotropic changes in the glioma TME, including glioma stem cell differentiation, modulation of the stroma, and immune cell activation and recruitment, thereby suggesting a possible role for enhancing immunotherapy in glioma patients.

Consistent with this notion, β-catenin inhibition using XAV939 or ICG-001 partially prevented centrinone-induced death and rescued the growth two APC-mutant organoid lines tested. Our study reveals a novel role for canonical WNT signaling in regulating centrosome loss-induced growth defect/death in a subset of APC-mutant colorectal cancer independently of the classical p53 pathway.

Experimental and bioinformatic data confirmed the relation between Wnt signaling and glycolytic enzymes in tongue cancer cells and HNSCC clinical samples. Overall, the inhibition of glucose metabolism by Wnt signaling inhibitors is a promising mode of action against tongue cancer cells.

We investigated the biological aspects related to LSC heterogeneity in CML patients and demonstrated the ability of specific small molecule CBP/β-catenin antagonists to safely eliminate deeply quiescent therapy resistant CSC. These observations may represent an attractive generalizable therapeutic strategy that could help develop better protocols to eradicate the quiescent LSC population.

In agreement, NFATc1 or NFATc2 specific gene silencing in 3 T-ALL GC resistant cell line models and primary cells increases dexamethasone response, by restoring GR canonical transcriptional activity through the increase expression of BIM GR target gene (p value <0.05). Overall, we revealed for the first time the involvement of NFATc1 and NFATc2 transcription factors in supporting GC resistance in T-ALL cells by the modulation of cholesterol biosynthesis and Wnt/β-catenin signaling, both processes well-described in sustaining chemotherapy resistance, paving the rationale to alternative therapeutic options for T-ALL GC resistant pediatric patients.

PRI-724-treated NASH mice not only recovered from NASH-related liver fibrosis through the effect of PRI-724 down-regulating the expression of pro-fibrotic genes and up-regulating the expression of anti-fibrotic genes, but they also recovered from NASH-induced liver disorder. PRI-724, a selective CBP/β-catenin inhibitor, thus shows a potent therapeutic effect for NASH-related liver fibrosis and for decreasing adipose tissue in the liver.

ICG-001 enhanced cisplatin-mediated cytotoxicity. Autophagy inhibition by ATG5 silencing enhanced ICG-001-mediated suppression of cell viability, tumor spheroid formation, and protein expression of cyclin A and CD44. This study clarified the mechanism and revealed the clinical potential of ICG-001 against endometrial cancer.

Here we show that co-treatment with abiraterone and ICG001, a β-catenin inhibitor, overcomes therapeutic resistance and significantly inhibited markers of stem cell and cellular proliferation in abiraterone-resistant prostate cancer cells. In addition, combined treatment inhibited tumor growth in an in vivo abiraterone-resistant xenograft model, blocked stemness, migration, invasion, and colony formation ability of cancer cells. This study opens new therapeutic opportunity for advanced-stage castration-resistant prostate cancer patients.

Rebalancing the equilibrium between CBP/β-catenin versus p300/β-catenin associated transcription, utilizing the small molecule CBP/beta-catenin antagonist ICG-001, enhances mitochondrial oxidative phosphorylation, metabolic function, and neuronal differentiation and may be able to ameliorate the cognitive decline seen in neurodegenerative disorders, including Alzheimer's Disease.

We previously developed ZG111, a potent ClpP agonist derived from ICG-001, inhibits the proliferation of pancreatic ductal adenocarcinoma cell lines in vitro and in vivo by degrading respiratory chain complex proteins...Finally, ZG36 treatment inhibited 3-D cell growth in vitro and suppressed the tumorigenesis of AML cells in xenografted mice models. Collectively, we developed a new class of human ClpP agonists that can be used as potential antileukemic therapies.

Mixtures of PRI-724 and vismodegib affected cell cycle distribution, greatly reduced cell migration, and downregulated the transcript level of CSC markers, especially POU5F1 encoding OCT4. Combinations of PRI-724 with erlotinib or HS-173 were more potent in inducing apoptosis.

Agaricus Blazei Extract FA-2-b-β inhibits cell proliferation, promotes apoptosis, regulates the cell cycle, reduces mitochondrial energy supply, and down-regulate MDR1 expression to reverse the resistance of CEM/C1, which all suggest it is through regulating the Wnt signaling pathway in T-ALL.

these data support the hypothesis that the emergence of differentiated tumour cells from postchemotherapy shock after chemotherapy is due to ectopic activation of WNT signalling pathway genes.

We observed that EGCG displayed greater efficacy than ICG-001 (β-catenin), SP600125 (JNK) and MK-2206 (AKT) inhibitors, and its effects were equivalent to verteporfin (YAP) or SB525334 (Smad) for regulating expression of key fibrotic mediators. These data indicate that EGCG exhibits anti-fibrotic effects in fibroid cells. These results provide insight into mechanisms behind the observed clinical efficacy of EGCG against uterine fibroids.

Then, we used ICG001 to block the Wnt/β-catenin signal transduction pathway, and the results revealed that ICG001 could reduce the promoting effect of low KDM6A expression on aggressiveness and EMT in GC cells...The EMT is inhibited by regulating theWnt/β-catenin signaling by KDM6A, which reduces GC cell proliferation, migration, and invasion. KDM6A may be a viable target for GC in clinical therapy.

Furthermore, resistance to paclitaxel was associated with higher responses to PRI-724, a CBP-β-CATENIN inhibitor. Neither WT nor KO epithelial subtypes were resistant to olaparib exposure. Therefore, we conclude that Wnt10b is essential to educate highly metastatic breast cancer stromal cells to promote growth, metastatic colonization, and resistance to paclitaxel.

Finally, the pathway inhibitors LY294002 and ICG001 were used to validate the role of the PI3K/Akt and Wnt/β‑catenin pathways in MC‑LR‑accelerated cell proliferation. Taken together, these data showed that MC‑LR promoted CRC cell proliferation by activating the PI3K/Akt/Wnt/β‑catenin pathway. The present study provided a novel insight into the toxicological mechanism of MC‑LR.

We find the WNT/-catenin inhibitors pyrvinium, ICG-001 and PKF118-310 attenuate growth of CRC cell lines in vitro with BRAF-mutant lines being relatively more sensitive...The selective and potent VEGFR inhibitor axitinib was most effective against BRAF-mutant CRC cell lines in vitro but addition of vemurafenib did not significantly increase these effects...The magnitude of these effects was comparable to that induced by a combination of vemurafenib and cetuximab. This was associated with additive effects on release from tumour cells and tumour microenvironment cell types of substances that would normally aid tumour progression. Taken together, this preclinical data indicates that the efficacy of BRAF inhibitor therapy in CRC could be increased by co-targeting either WNT/β-catenin or VEGFRs with small molecule inhibitors.

Lastly, using an in vivo lung metastasis assay, we showed that ICG-001 transient overexpression of miR-134 or stable overexpression of miR-134 could significantly reduce the lung metastasis of NPC cells. Taken together, we present here evidence that modulation of Wnt/β-catenin signaling pathway could inhibit the metastasis of NPC through the miR-134/ITGB1 axis.

Functional rescue experiments demonstrated that overexpression of WNT10B reversed the tumor suppressive roles of CTB-193M12.5 knockdown, while Wnt/β-catenin signaling inhibitor ICG-001 abolished the oncogenic roles of CTB-193M12.5 overexpression. CTB-193M12.5 was a highly expressed and poor prognosis-related lncRNA in HCC. CTB-193M12.5 functioned as an oncogenic lncRNA through promoting NSD1-mediated WNT10B/Wnt/β-catenin signaling activation.

ZnO NPs combined with ICG-001, a β-catenin inhibitor, showed a synergistic inhibitory effect on OS lung metastasis and a longer survival time. In addition, tissue microarray (TMA) of OS patients also detected much higher β-catenin expression which indicated the role of β-catenin in OS development. In summary, our current study not only proved that ZnO NPs can inhibit OS metastasis by degrading β-catenin in HIF-1α/BNIP3/LC3B-mediated mitophagy pathway, but also provided a far-reaching potential of ZnO NPs in clinical OS treatment with metastasis.

The β-catenin small-molecule inhibitor, ICG-001, is proposed to prevent β-catenin in the nucleus from being able to perform CBP-dependent stemness-related transcription during canonical Wnt/β-catenin signaling pathway. We suggest that β-catenin inhibitor and cisplatin combination resulted into significant regression of tumor growth in BRCA mutant TNBC cells.

Functional analyses using GSCs derived from a murine de novo GBM model induced by oncogenic genes transduction using the Sleeping-Beauty transposon system revealed that expression of Stat5b was induced by culturing under hypoxia together with Lgr5, repressed by Hif2α knockdown, and reduced by Lgr5 knockdown or a Wnt/β-catenin signaling inhibitor ICG-001 treatment...Disruption of Stat5b in an orthotopic transplantation model significantly prolongs event-free survival. These results suggest that Stat5b, regulated by hypoxia and the Wnt pathway, plays an important role in the maintenance and tumorigenicity of GSCs and may be a promising therapeutic molecular target to attack GSCs.

The unique mutational processes in NAFLD-liver and NAFLD-HCC alludes to a "field effect". Whereby, distinct aberrations and shift in driver events reveal a gain-of-function role of CTNNB1 mutations in immune exclusion via TNFRSF19 inhibition of SASP-like features.

Therefore, ICG-001 may potentially become an essential component of treatment de-escalation regimens for HPV-positive HNSCC. Further studies are warranted for additional assessment of the mechanistic background of our in vitro findings.

In parallel, we showed the efficacy of TAS-120/ICG-001 FGFR-Wnt/β-catenin inhibitor combination liposomes decorated with GPR77 and CD10 targeting antibodies to switch the acquired activated CAFs phenotype to a quiescent one. Co-administration of both liposomes in low drug doses significantly enhanced the infiltration of cytotoxic CD8+ T cells and improved the antitumor efficacy of αPD-L1 antibody in LLC syngeneic mice model of lung cancer. In conclusion, simultaneous blockage of the tumoral exosome-mediated activation of fibroblasts and FGFR-Wnt/β-catenin signaling may constitute an outstanding immunotherapeutic modality.

Together, our data identify activation of the β-catenin pathway as a major mechanism contributing to abiraterone resistance and demonstrate that combined treatment with abiraterone and ICG001 appears to be an effective regimen for treatment of abiraterone-resistant cancer cells. This opens new therapeutic modality for advance-stage castration-resistant prostate cancer patients.

ICG-001 is a specific inhibitor for β-catenin/CBP but not for β-catenin/p300...Taken together, AP-1 possibly coordinates β-catenin coactivator usage in PANC-1 cells. These results would further our understanding of the canonical Wnt/β-catenin signaling divergence.

Collectively, our findings suggest that ICG-001 efficiently inhibits CRC stemness and metastasis by suppressing MEIS1 expression. These results provide a basis for the further clinical investigation of ICG-001 as a targeted therapy for CSCs, opening a new avenue for the development of novel Wnt inhibitors for the treatment of CRC metastasis.

In conclusion, our results demonstrated that combination of AF and ICG-001 suppressed the proliferation and metastasis of colon cancer by inhibiting STAT3 phosphorylation. Therefore, this combination therapy may possess potential therapeutic properties for human colon cancer.

Moreover, LiCl or ICG-001 exposure counteracted the effects of AHNAK2 silencing or upregulation on malignant phenotypes of TC cells. In conclusion, the knockdown of AHNAK2 restrained the proliferation, metastasis, and EMT of TC cells by inhibiting the Wnt/β-catenin pathway, providing a new potential mechanism of AHNAK2 in understanding the oncogenesis and progression of TC.

Blockade of the β-catenin signaling by ICG-001 markedly impeded the promoting effects of PIMREG on glioma cell proliferation and invasion. In conclusion, PIMREG acts as a tumor promoter in glioma at least partly via activating the β-catenin signaling pathway. This study provides new insights into the molecular mechanism for glioma pathogenesis and treatment.

Immature and lipopolysaccharide-matured dendritic cells prepared from healthy blood donor buffy coats were stimulated with 6-bromoindirubin-3'-oxime (6-BIO) to boost basal β-catenin activity, and the effects of axitinib and nitazoxanide were compared with the commercial β-catenin inhibitor ICG-001. Axitinib stimulated several aspects of dendritic cell function, such as IL12-p70 secretion, and counteracted IL-10 secretion, according to the present study. However, neither axitinib nor nitazoxanide were found to be efficient β-catenin inhibitors in monocyte-derived dendritic cells.

The inhibitors GM6001, BB94, and ICG-001 suppressed the migration and invasion of cancer cells with ARID1A-deficiency. Our findings provide novel insights into the mechanism of ARID1A metastasis and offer a scientific basis for targeted therapy of ARID1A-deficient cancer cells.

This paper proposes the hypothesis that Sam68 and Pygo2 are responsible for cell type-specific response of CRC cell lines cotreated with ICG-001 and butyrate as well as other HDACis. Further, experiments are proposed to evaluate this hypothesis and consider possible expected results that could be obtained from such studies.
