Abstract: Disclosed is a complex immuno-gene medical composition for activating NK cells to enhance a host immune system. The composition includes a plurality of cytokines, including Th1 and Th2 cytokines. Th2 cytokines antagonize TGF-? inhibiting NK cells to disable the inhibition of the immune system. Th1 cytokines activate NK cells in a host to enhance the host's ability to fight against tumor cells. By use of the complex immuno-gene medical composition, removal of tumor cells is expected.

Abstract: Dominant negative alleles of human mismatch repair genes can be used to generate hypermutable cells and organisms. By introducing these genes into cells and transgenic animals, new cell lines and animal varieties with novel and useful properties can be prepared more efficiently than by relying on the natural rate of mutation. The enhanced rate of mutation can be further augmented using mutagens. Moreover, the hypermutability of mismatch repair deficient cells can be remedied to stabilize cells or mammals with useful mutations.

Abstract: The present invention provides a prophylactic and/or therapeutic agent for pulmonary hypertension, comprising an antagonistic mutein of MCP-1 or a salt thereof, a DNA molecule comprising a nucleotide sequence encoding the antagonistic mutein of MCP-1, or a neutralizing antibody against MCP-1. The antagonistic mutein of MCP-1 or a salt thereof, the DNA molecule having a nucleotide sequence encoding the antagonistic mutein of MCP-1, or the neutralizing antibody against MCP-1 has hypotensive activity, and thus is useful as a pharmaceutical agent for preventing and/or treating pulmonary hypertension (primary pulmonary hypertension, in particular).

Abstract: Recombination in mammalian somatic cell chromosomes is promoted and marked by a method called mosaic analysis with double marker (MADM). Mouse “knock-in” techniques are used to create pairs of chromosomes in which recombinase target sites are placed at homologous chromosomal locations. The knock-in constructs are engineered so that cellular markers, such as green or red fluorescent protein (GFP or RFP), are only expressed after recombinase-induced recombination. This system provides high-sensitivity detection of recombinase-induced mitotic recombination, even down to the single cell level. When this recombination is induced in a mouse heterozygous for a mutation in a gene distal to the “knock-in” locus on the same chromosome, it results in homozygosity of this mutation in the labeled cells. This allows the analysis in singly-labeled neurons of genes whose pleiotropic effects might otherwise result in early lethality.

Abstract: The present invention provides an experimental model animal which does not develop anaphylaxis, a type I allergy, can specifically induce Arthus reaction, a type III allergy, is not affected by type I allergy and evaluates type III allergy inflammation individually, and a method of screening a reaction accelerating or inhibitory substance in a type III allergy reaction through Fc?RIII by using said experimental model animal. In order to eliminate Fc?RIIB that demonstrates suppressive action to response through Fr?RIII, a mouse wherein the deletion mutation of both molecules of Lyn and Fc?RIIB are homozygotic (Lyn?IIB?) was generated by mating Lyn knockout mouse (Lyn?/?) and Fc?RIIB knockout mouse (Fc?RIIB?/?), and was used to measure and evaluate the deficiency of Fc?RIII function in systemic passive anaphylaxis and the reduction of Fc?RIII function in a bone marrow-derived mast cell, or the like.

Abstract: The present invention relates to a method of increasing the live weight of poultry through the administration of a plasma product to the poultry through the animals' feed and/or water. The product is effective in increasing the live weight of poultry. The product is also surprisingly effective in increasing the yield of white meat to the detriment of dark meat.

Abstract: Provided is a special Drosophila strain having a Bradeion gene artificially incorporated therein to exclusively express the gene in the compound eyes and thus to exhibit rough eye. The Drosophila strain has the following properties: (a) a human-derived Bradeion gene has been transferred in the strain to express the human-derived protein Bradeion in the compound eyes from the developmental period; (b) the compound eyes show morphological abnormality due to the expression of Bradeion; and (c) the morphological abnormality occurring in the compound eyes is multiplied according to the number of transferred Bradeion genes.

Abstract: The invention provides a transgenic pig having incorporated into its genome a HSP70 gene or fragment thereof, whereby the transgenic pig overexpresses HSP70. The transgenic pig of the invention can be used in the production of HSP in large quantities, as a xenograft source for transplation and as an animal model close to human for illustrating the protective roles of HSP. Furthermore, the transgenic pig of the invention has a better meat quality and exhibits an increased growth rate and a reduced backfat thickness.

Abstract: The present invention provides methods of producing transgenic livestock animals. The methods generally involve first introducing a nucleoprotein made up of nucleic acid and a recombinase into a totipotent or pluripotent cell to produce a recombinant totipotent or pluripotent cell and then growing the recombinant totipotent or pluripotent cell to produce the transgenic livestock animal. The invention further provides kits for use in generating transgenic non-human animals of the invention.

Abstract: An object of the present invention is to provide a remedy for dysfunction of central monoamine pathway, a method for screening a PTP? inhibitor or activator, and a non-human model animal being hyposensitive to a stimulant drug, After administering a subject material to PTP? knockout mice and wild-type mice, PTP? activity in the PTP? knockout mice and the wild-type mice is compared and evaluated to screen a PTP? inhibitor or activator. Examples of the comparison and the evaluation of the PTP? activity include the comparison and the evaluation of the function of central monoamine pathway such as changes in the level of central monoamine metabolism, sensitivity to a stimulant drug, the presence of dysfunction of mesolimbic dopamine pathway, level of acclimation to new circumstances, or stress-responsiveness.
