Apoptotic resistance remains a hallmark of glioblastoma (GBM), the most common primary brain tumor in adults, and a better understanding of this process may result in more efficient treatments. By utilizing chromatin immunoprecipitation with next-generation sequencing (CHIP-seq), we discovered that GBMs harbor a super enhancer around the Mcl-1 locus, a gene that has been known to confer cell death resistance in GBM.We utilized THZ1, a known super-enhancer blocker, and BH3-mimetics, including ABT263, WEHI-539, and ABT199. Combined treatment with BH3-mimetics and THZ1 led to synergistic growth reduction in GBM models. Reduction in cellular viability was accompanied by significant cell death induction …

Metastasis is the leading cause of cancer deaths worldwide. However, there exist only limited treatment options and they are often ineffective. An important aspect of metastasis that requires study, but has previously been understudied is circulating tumor cells (CTCs). CTCs are a critical step in the metastatic cascade. They can be analyzed for the identification of key mechanisms in metastasis. To this end, we isolated CTCs from a syngeneic mouse model of hepatocellular carcinoma (HCC) and a human xenograft mouse model of castration-resistant prostate cancer (CRPC). From these mouse models, primary tumor and CTC lines were established. Functional characterization of …
