Abstract: The onset ratios and pathological conditions of collagen-induced arthritis and adjuvant arthritis in model mice and rats, respectively, were successfully ameliorated by topically expressing the cyclin-dependent kinase inhibitors p161NK4a and p21Cip1 in articular tissues using adenoviral vectors. In the synovial cells of CDKI-transduced mice, expression of inflammatory cytokines was inhibited. Described are the use of the p21Cip1 protein for inhibiting abnormal proliferation of synovial tissues, inflammation in synovial tissues and/or expression of inflammatory cytokines in synovial tissues; the p21Cip1 gene; compounds promoting the activity or expression of the p21Cip1 protein; and pharmaceutical compositions containing these molecules. Also provided are method of screening for compounds participating in the abnormal proliferation of synovial tissues, inflammation in synovial tissues and/or the expression of inflammatory cytokines in synovial tissues targeting the p21Clip1 protein.
Abstract: The present invention provides a method for producing customized pluripotent stem cells. Specifically, the present invention comprises following steps: extracting proteins from any of the dedifferentiated stem cells or induced pluripotent stem cells, the said dedifferentiated or pluripotent stem cells being prepared by any known method; introducing the protein extract into the adult somatic cells; and culturing the adult somatic cells to produce pluripotent stem cells having the same pluripotency as that of embryonic stem cells. In addition, pluripotent stem cells produced according to the present method and cell therapeutics comprising the same are provided. The method allows pluripotent stem cells to be produced very easily and at a significantly higher yield, compared to typical methods.

Abstract: The invention relates to the generation of non-human transgenic animals comprising a reporter construct for producing a detectable amount of a reporter molecule operably linked to a transcriptional regulatory nucleic acid molecule from the human CYP3A4 gene located between the initiation of transcription site of the gene and a position located 13,000 nucleotides upstream from the site. The invention also relates to the use of these animals for determining the effect of a compound, particularly, but not exclusively, a xenobiotic or steroid, on the regulation of expression of the CYP3A4 gene in a human.

Abstract: The present invention relates to transgenic non-human animals, tissues or cells derived therefrom and methods of producing them. The transgenic non-human animals or tissues or cells derived therefrom provide a system capable of expressing human proteins responsible for drug metabolism in place of the homologous endogenous non-human animal proteins and for the controlled expression of human genes introduced into the animal so that the expression of the human genes is regulated in a manner more closely analogous to that seen in vivo in humans. One aspect of the invention relates to the use of a human DNA sequence comprising at least part of introns 6 and/or 7 of the human PXR gene.
