Recent studies, however, have suggested that inhibitors of various general transcriptional regulators can be used in cancer therapy because expression of some oncogenes is disproportionately sensitivity to these inhibitors. Here, I describe the cellular and molecular effects of inhibiting a general transcriptional regulator, CDK7, in T-cell acute lymphoblastic leukemia (T-ALL) cells. Because tumor cells commonly evolve resistance to individual therapies, I have also investigated the potentially synergistic effects of combining two compounds that target transcriptional regulators - the CDK7-inhibitor THZ1 and the BRD4-inhibitor JQ1 - and suggest a model describing the molecular basis of the synergistic effects I observed. My research provides insight into the effects of these inhibitors of general transcriptional regulators on tumor cell behavior and gene expression programs.","abstract_html":"Transcription is frequently deregulated in cancer, but targeting of transcriptional processes for cancer therapy has thus far been limited to nuclear receptors.
