A recent study suggested that increased copy numbers of the AMY2B gene might be a crucial genetic change that occurred during the domestication of dogs. To investigate AMY2B expansion in ancient breeds, which are highly divergent from modern breeds of presumed European origins, we analysed copy numbers in native Japanese dog breeds. Copy numbers in the(More)
A WKA rat fetus-derived fibroblast cell line WFB showed strict nontransformant phenotypes in vitro such as anchorage dependency of cell growth in soft agar, contact inhibition, and serum dependency on the monolayer cell culture. Transfection of 6.6-kilobase EJras oncogene into WFB resulted in the acquisition of tumorigenicity in vitro and in vivo. The cell(More)
We examined integrase-defective lentiviral vectors (IDLVs) with a mutant (D64V) integrase in terms of their residual integration capability, the levels and duration of transgene expression and their therapeutic potential in comparison to wild-type lentiviral vectors (WTLVs) with a wild-type integrase gene. Compared with WTLVs, the IDLV-mediated proviral(More)
A 64-year-old man with essential thrombocythemia was admitted to our hospital because of cardiac failure. Echocardiography revealed severe mitral regurgitation and a gallbladder tumor was detected incidentally by ultrasonography. Although the gallbladder tumor was strongly suspected to be malignant, we considered that the radical operation would be possible(More)
