Abstract: There are disclosed a nucleic acid whose expression is enhanced in human neuroblastoma with unfavorable prognosis based on comparison between human neuroblastoma with favorable prognosis and human neuroblastoma with unfavorable prognosis, the nucleic acid comprising any one of base sequences set forth in SEQ ID NO:1 to NO:69 in the Sequence Listing, a nucleic acid comprising a portion of any of those base sequences, and an isolated nucleic acid capable of hybridizing to a complementary base sequence of the foregoing under stringent conditions. It discloses gene sequences relating to favorable or unfavorable prognosis of neuroblastoma and will enable the provision of their genetic information and the diagnosis of favorable or unfavorable prognosis.

Abstract: There are provided base sequence data for human kinesin-related genes with a motor domain, as well as information relating to the functions of the proteins encoded by the human kinesin-related gene and the motor domain-lacking human kinesin-related gene, which data may be utilized for diagnosis (for example, judging prognosis of neuroblastoma) and treatment (particularly as antisense nucleic acids for malignant tumors).

Abstract: There are disclosed a nucleic acid which is derived from the gene expressed in human neuroblastoma, and which comprises any sequence selected from the group consisting of the nucleic acid sequences set forth SEQ ID NO:1 to NO:104 in the Sequence Listing, or its complementary nucleic acid; a fragment of the nucleic acid; their use as probes or primers; and the diagnosis of neuroblastoma prognosis using any of the foregoings.

Abstract: A microarray for predicting the prognosis of neuroblastoma, wherein the microarray has 25 to 45 probes related to good prognosis, which are hybridized to a gene transcript whose expression is increased in a good prognosis patient with neuroblastoma and are selected from 96 polynucleotides consisting of the nucleotide sequences of Seq. ID No. 1 to 96 or their partial continuous sequences or their complementary strands, and 25 to 45 probes related to poor prognosis, which are hybridized to a gene transcript whose expression is increased in a poor prognosis patient with neuroblastoma and are selected from 104 polynucleotides consisting of the nucleotide sequences of Seq. ID No. 97 to 200 or their partial continuous sequences or their complementary strands.

Abstract: An improved mutant vaccinia virus providing a pock and plaque size on RK13 cells that is approximately the same as those of the Lister original, having a proliferation potency on YTV cells that is approximately the same as that of the Lister original, and having a neurovirulence, assessed by a recovery of an intrabrain virus, that is lower than that of the Lister original; and a process for the production thereof.
