Abstract: A method to treat hepatoma with dengue viruses which infect liver tumor stem cells for annihilation of hepatocellular carcinoma tissues. The liver tumor stem cells expressing the biomarker of CD133 in a tumor part are the objects infected by dengue viruses preferentially and killed due to specific protein expressions for suppression of hepatoma.

Abstract: Disclosed is an HSV-1-derived vector containing a DNA having a functional LAT promoter, or operative fragment thereof, a deletion in both copies of the HSV-1 LAT gene, and a deletion in both copies of the HSV-1 ICP34.5 gene. The HSV-1-derived vectors are non-neurovirulent and do not spontaneously reactivate from latency, and they optionally contain a functional HSV thymidine kinase gene, which can enhance the effectiveness against cancer of drug treatment with gancyclovir or acyclovir. Alternatively, the HSV-1-derived vectors contain at least one transcriptional unit of a LAT promoter sequence operatively linked to a nucleic acid encoding a preselected protein. In some embodiments, the preselected protein is a nucleotide sequence encoding a polypeptide toxic for cells expressing the vector, for example, human interferon-?. Also, disclosed are kits for expressing in a mammalian cell a gene encoding a preselected protein, and mammalian cells containing the HSV-derived vectors.

Abstract: Disclosed is a method of selectively inhibiting the growth of malignant cells in mammals, including humans. The method selectively inhibits the growth of malignant cells of all varieties, and is particularly useful in treating brain tumors and other malignancies of the central nervous system. The method employs HSV-1-derived vectors containing a DNA having a deletion in both copies of the LAT gene and both copies of the ICP34.5 gene of HSV-1. The vectors are delivered to malignant cells either in vivo or in vitro, in accordance with the method. The HSV-1-derived expression vectors are non-neurovirulent and do not spontaneously reactivate from latency, and they optionally contain a functional HSV thymidine kinase gene, which can enhance the effectiveness against cancer of drug treatment with gancyclovir or acyclovir.

Abstract: A chromosomal gene of Borrelia burgdorferi which encodes a conserved antigen of approximately 79 kD has been isolated and sequenced. The chromosomal gene, the gene product, and antibodies to the gene product may be used in diagnostic methods for the detection of Borrelia burgdorferi infection. The antigen and fragments thereof are suitable for use in vaccine compositions and methods.
