  • Patent number: 10328050
    Abstract: Systems and methods for determining whether a cancer patient may respond to inhibition of RNA polymerase II as a treatment for the patient are provided. Inhibition of RNA polymerase II may be by way of chemotherapy with an agent such as triptolide, an analog of triptolide, or a prodrug form of triptolide. The cancer patient may be a pancreatic cancer patient, an ovarian cancer patient, a gastric cancer patient, or an esophageal cancer patient. The patient may have any cancer in which c-Myc is over-expressed or over-amplified.

  • Patent number: 8324188
    Abstract: A method to determine the utility of small molecules as functional replacements (mimetics) for protein receptor ligands is described. The method uses cellular biological assays on a systematic array of compounds, comprising known protein receptor ligands and other biologically active molecules to determine if a proposed small molecule is a functional equivalent of a receptor ligand, having therapeutic utility as a pharmaceutically relevant and useful agent either alone or in combination with other molecules. Furthermore, the invention provides for a method for the treatment of cancer comprising administering a combination of ET-18-O-CH3 and an anti-cancer agent.

  • Patent number: 6589773
    Abstract: The present invention relates to novel yeast cells with increased permeability to compounds, such as small organic compounds. In particular, the invention provides genetically modified yeast cells carrying functional, preferably conditionally regulated, copies of HXT9 and HXT11 genes integrated in the chromosome at the PDR1 and PDR3 loci, thereby disrupting the PDR1 and PDR3 gene activity. The invention further relates to methods and compositions for the use of these hyperpermeable yeast cells for screening for compounds that modulate macromolecular interactions. The invention is exemplified by the use of the hyperpermeable yeast cells in such a screening system. In addition, the invention further provides methods of producing the yeast cells of the invention, as well as polynucleotides, vectors, and kits for use of the hyperpermeable yeast cells and the screening methods of the invention.
