Patent number: 7179797Abstract: A DNA vaccine for the treatment of prostate cancer, comprising a plasmid vector comprising a nucleotide sequence encoding prostatic acid phosphatase (PAP) operably linked to a transcription regulatory element, wherein upon administration to a mammal a cytotoxic immune reaction against cells expressing PAP is induced. In preferred embodiment, the PAP encoded is a xenoantigen highly homologous to the autoantigen PAP of the mammal. Also disclosed are methods for inducing prostatitis, or inducing immune reaction to PAP, or treating prostate cancer in a mammal, using the DNA vaccine and pharmaceutical compositions comprising the vaccine. Preferably, xenoantigen vaccination is followed by boosting with autoantigen PAP from the same animal species as the mammal being treated.Type: GrantFiled: September 25, 2003Date of Patent: February 20, 2007Assignee: Wisconsin Alumni Research FoundationInventor: Douglas McNeel

Patent number: 7105717Abstract: To provide a rat model with the onset of prostate cancer in which the prostate cancer including an invasive cancer can be developed and can be bred for generations stably. A rat model with the onset of prostate cancer which can develop prostate cancer including invasive cancer and can be bred for generations stably is established by: ligating an SV40 large T antigen gene onto the downstream of rat probasin gene promoter; the resulting PBSVT transgene is introduced into a fertilized egg of a Sprague-Dawley rat; after the introduction, the fertilized egg is transplanted into a recipient rat; a transgenic rat obtained from the recipient rat is then mated with a wild-type Sprague-Dawley rat; the transgenic offspring rats thus obtained are similarly can be bred for generations thereafter; and transgenic rats developing prostate cancer are selected through histopathological observation of the prostate.Type: GrantFiled: June 13, 2000Date of Patent: September 12, 2006Assignee: Japan Science and Technology AgencyInventors: Tomoyuki Shirai, Makoto Asamoto, Satoru Takahashi

Patent number: 7078500Abstract: Nucleic acid molecule that comprise a hepatitis C nonstructural protein including specifically disclosed DNA sequences are disclosed. Pharmaceutical compositions that contain nucleic acid molecules comprising a hepatitis C nonstructural protein including a nucleotide sequence encoding NS3, NS4, or NS5, or a combination thereof, operably linked to regulatory elements functional in human cells are disclosed. Methods of immunizing individuals susceptible to or infected by hepatitis C virus comprising administering such pharmaceutical compositions are disclosed.Type: GrantFiled: January 28, 1999Date of Patent: July 18, 2006Assignee: The General Hospital CorporationInventors: Jack Wands, Jens Encke

Patent number: 7045678Abstract: A transgenic, non-human mammal useful for assessing the effect of candidate chemotherapeutic drugs on the growth of brain tumors in vivo is provided. Incorporated into the genome of the transgenic mammal, which preferably is a rodent, is a transgene which comprises a promoter comprising the nuclear factor binding region of the RR2 cis acting element of a fibroblast growth factor 1B (FGF1B) promoter. Operably linked to the promoter is reporter gene comprising a sequence which encodes the SV40 large T antigen. A transgenic, non-human mammal useful for identifying and isolating FGF1 producing brain cells. Incorporated into the genome of these transgenic animals is a transgene which comprises a promoter comprising the nuclear factor binding region of the RR2 cis acting element of an fibroblast growth factor 1B (FGF1B) promoter. Operably linked to the promoter is reporter gene comprising a sequence which encodes a protein or polypeptide other than an SV40 large T antigen.Type: GrantFiled: April 22, 2004Date of Patent: May 16, 2006Inventor: Ing-Ming Chiu

Patent number: 7041869Abstract: The present invention provides a transgenic animal expressing the reporter gene, luciferase, driven by a promoter (e.g. the E2F1 promoter) that acts as a sensor of cell cycle. The luciferase substrate, luciferin, emits light when metabolized, and the light is transmitted through mammalian tissues. Therefore, the transgenic animal model of the present invention allows for monitoring of areas of major cell cycle activity, a characteristic of cancer cells, under adequate visualization conditions. These transgenic animals are useful as in vivo models for testing preventative measures for cancer as well as for testing novel therapeutic modalities.Type: GrantFiled: October 3, 2003Date of Patent: May 9, 2006Assignee: Sloan-Kettering Institute for Cancer ResearchInventor: Eric Charles Holland

Patent number: 7037903Abstract: A method for using thymosin ?-10 for cancer treatment by expressing thymosin ?-10 in solid malignant tumor cells. More precisely, the present invention relates to a cancer treatment method wherein thymosin ?-10 is expressed in solid malignant tumor cells by infecting adenovirus including thymosin ?-10. The gene therapy for cancer using thymosin ?-10 of the present invention is very effective for the treatment of ovarian cancer, cervical cancer, stomach cancer and lung cancer.Type: GrantFiled: August 30, 2002Date of Patent: May 2, 2006Inventors: Je-Ho Lee, Seung-Hoon Lee

Patent number: 7030098Abstract: A pro-inflammatory T cell response is specifically suppressed by the injection into a recipient of DNA encoding an autoantigen associated with autoimmune disease. The recipient may be further treating by co-vaccination with a DNA encoding a Th2 cytokine, particularly encoding IL4. In response to the vaccination, the proliferation of autoantigen-reactive T cells and the secretion of Th1 cytokines, including IL-2, IFN-? and IL-15, are reduced.Type: GrantFiled: September 5, 2001Date of Patent: April 18, 2006Assignee: The Board of Trustees of the Leland Stanford Junior UniversityInventors: Lawrence Steinman, Pedro Ruiz, Hideki Garren
