Activation status of the Pregnane X Receptor (PXR) influences Vemurafenib availability in humanized mouse models

Vemurafenib is a revolutionary treatment for melanoma, but the magnitude of therapeutic response is highly variable and the rapid acquisition of resistance is frequent. Here, we examined how vemurafenib disposition, particularly through cytochrome P450...

Generation of a mouse model of atypical teratoid/rhabdoid tumor of the central nervous system through combined deletion of Snf5 and p53

Malignant rhabdoid tumors arise in several anatomic locations and are associated with poor outcomes. In the brain, these tumors are known as atypical teratoid/rhabdoid tumors (AT/RT). While genetically engineered models for malignant rhabdoid tumors ex...

CD73 is associated with poor prognosis in high-grade serous ovarian cancer

The cell surface nucleotidase CD73 is an immunosuppressive enzyme involved in tumor progression and metastasis. While preclinical studies suggest that CD73 can be targeted for cancer treatment, the clinical impact of CD73 in ovarian cancer remains uncl...

A TDO2-AhR Signaling Axis Facilitates Anoikis Resistance and Metastasis in Triple-Negative Breast Cancer

The ability of a cancer cell to develop resistance to anoikis, a programmed cell death process triggered by substratum detachment, is a critical step in the metastatic cascade. Triple-negative breast cancers (TNBC) exhibit higher rates of metastasis af...

Radioprotection of IDH1-mutated cancer cells by the IDH1-mutant inhibitor AGI-5198

Isocitrate dehydrogenase 1 (IDH1) is mutated in various types of human cancer to IDH1R132H, a structural alteration that leads to catalysis of α-ketoglutarate to the oncometabolite D-2-hydroxyglutarate. In this study, we present evidence that small mo...
