Publication number: 20110300109Abstract: The present invention is based, in part, on our discovery of compositions and methods that can be used to systemically deplete arginine and thereby treat arginine-dependent cancers. Our studies indicate that administering a composition that depletes arginine directly to the patient's small intestine will provide effective treatment for arginine-dependent cancers. Moreover, the methods can be carried out in such a way that various sources of arginine are restricted and side effects are minimized. For example, to deplete arginine, one can not only administer an arginine-depleting enzyme directly to the intestinal lumen but can also inhibit endogenous production of arginine, reduce arginine production by intestinal bacteria and limit arginine intake. To minimize side effects, one can inhibit protein breakdown, which may occur as a compensatory mechanism, provide systemic NO from a nitric oxide donor, provide a pressor peptide, and/or provide prostacycline or an analog thereof.Type: ApplicationFiled: August 25, 2009Publication date: December 8, 2011Applicant: Kyon Biotech AGInventors: Slobodan Tepic, Goran Cvetkovic

Patent number: 8017375Abstract: There is disclosed a method of producing isobutanol. In an embodiment, the method includes providing a microorganism transformed with an isobutanol producing pathway containing at least one exogenous gene. The microorganism is selected to produce isobutanol from a carbon source at a yield of at least 10 percent theoretical. The method includes cultivating the microorganism in a culture medium containing a feedstock providing the carbon source, until isobutanol is produced. The method includes recovering the isobutanol. In one embodiment, the microorganism is a yeast with a Crabtree-negative phenotype. In another embodiment, the microorganism is a yeast microorganism with a Crabtree-positive phenotype. There is disclosed a microorganism for producing isobutanol. In an embodiment, the microorganism includes an isobutanol producing pathway containing at least one exogenous gene, and is selected to produce a recoverable quantity of isobutanol from a carbon source at a yield of at least 10 percent theoretical.Type: GrantFiled: December 23, 2008Date of Patent: September 13, 2011Assignee: Gevo, Inc.Inventors: Reid M. Renny Feldman, Uvini Gunawardena, Jun Urano, Peter Meinhold, Aristos A. Aristidou, Catherine Asleson Dundon, Christopher Smith
