DCAF7 is up-regulated in various tumours and correlates with poor prognosis, particularly in LIHC. High DCAF7 expression is linked to CD4+ T cell infiltration, up-regulation of immune checkpoint genes and increased tumour mutational burden, suggesting a role in tumour immune escape. DCAF7 stabilises β-catenin by enhancing GSK-3β Ser9 phosphorylation, thereby driving c-Myc/cyclin D1 expression and contributing to proliferation and migration in LIHC. DCAF7-high tumours demonstrate therapeutic vulnerability to 17-AAG, docetaxel and CDK/GSK-3 inhibitor, revealing potential targeted treatment strategies.

Co-treatment with the tankyrase inhibitor XAV-939 and RSL3 enhanced growth inhibition of eCCA cells, indicating that WNT signaling contributed to ferroptosis resistance. These findings indicate that iCCA exhibits a preferential dependency on GPX4, whereas WNT-β-catenin signaling mediates resistance in eCCA. Collectively, the results clarify the molecular basis of subtype-specific ferroptosis vulnerability and offer a rationale for combinatorial therapeutic strategies that integrate GPX4 and WNT pathway inhibition when treating refractory eCCA.

High YEATS2 expression activates Wnt/β-catenin signaling to promote EMT in GC and is correlated with poor prognosis of GC patients.

KDM1A regulates CRC progression by modulating epithelial-mesenchymal transition (EMT), metabolism, and Wnt signaling. Targeting KDM1A with GSK2879552 represents a promising therapeutic strategy for CRC treatment.

Importantly, treatment with XAV-939, a specific Wnt/β-catenin pathway inhibitor, abrogated the pro-oncogenic effects of SAMD4B overexpression, including Wnt/β-catenin pathway activation, enhanced proliferation, and increased metastatic capacity...In summary, our findings clarify that SAMD4B exerts an oncogenic role in breast cancer progression by activating the Wnt/β-catenin pathway. These data identify SAMD4B as a potential therapeutic target in breast cancer, although further in vivo investigations are required to validate its clinical relevance.

Pharmacological interventions using Wnt3a (activation) and XAV939 (inhibition) modulated Wnt/β-catenin signaling, while CRISPR/Cas9-mediated RelB knockout and plasmid-based overexpression established isogenic cell models...This plant-derived alkaloid exerts anti-HCC effects through Wnt pathway modulation, while compensatory RelB activation constrains therapeutic outcomes. Strategic RelB co-targeting establishes a dual pathway phytotherapy paradigm, synergistically merging botanical pharmacodynamics with precision oncology.

Additionally, a machine learning model trained on 236 known Tankyrase inhibitors accurately predicted pIC₅₀ values, with compound 138594346 (pIC₅₀ = 7.70) closely matching the reference inhibitor (pIC₅₀ = 7.71), and 138594428 also exhibiting strong predicted activity (pIC₅₀ = 7.41). Collectively, these results highlight 138594346 and 138594428 as promising candidates for further experimental validation in the development of targeted CRC therapeutics.

Basroparib (STP1002) was shown to be a safe and well-tolerated tankyrase-selective inhibitor with preliminary anti-tumor activity warranting further investigation.

JPI-547 outperformed most PARP inhibitors, with a half-maximal inhibitory concentration approximately 10-fold lower than that of olaparib. PDAC cells reliant on Wnt signaling due to pathogenic RNF43 mutations showed increased susceptibility to JPI-547 without altering homologous recombination repair efficiency. JPI-547 disrupts the Wnt/β-catenin pathway in RNF43-mutated cells and inhibits the oncogenic YAP pathway, highlighting its multifaceted therapeutic potential in PDAC with HRD or Wnt-addiction.

Collectively, these findings underscore the effectiveness of combining machine learning and system biology to accelerate rational drug discovery. Olaparib emerges as a promising candidate for TNKS-targeted therapy, providing a strong computational foundation for experimental validation and future preclinical drug development.

Functional rescue experiments confirmed that BGN overexpression reverses the inhibitory effects of GLIS2 knockdown, while the Wnt/β-catenin inhibitor XAV-939 effectively blocks BGN's tumor-promoting effects. These findings establish the crucial role of the GLIS2-BGN-Wnt/β-catenin axis in regulating GC EMT and identify novel potential therapeutic targets for GC treatment.
