TGF-p receptor mutation is now considered as one of the carcinogenic process of many tumors. To evaluate whether there is an abnormality in TGF-p type II receptor in osteosarcoma cell lines, we performed Northern analysis, cross-linking assay, luciferase activity and TGF-p growth inhibition assay in four osteosarcoma cell lines: G292, U202, HOS and SaOS. We also transfected the tumor cells with normal TGF-p type II receptor sequence to find if there is a possibility of gene therapy in osteosarcoma. In Northern analysis, Type II receptor expressions were decreased at SaOS, U202 and HOS cell lines. In cross-linking assay, all four cell lines didnt show type II receptor at their cell surface. The growth of these tumor cells were not suppressed by TGF-p. From these findings, we concluded that the normal production of TGF-p type II receptor was impaired in osteosarcoma. The transfection of these tumor cells with normal type II receptor sequence restored growth inhibition by TGF-p. This means even though TGF-p type II receptor is abnormal in osteosarcoma, we can restore its function by transfection of normal sequence. We think that the TGF-p type Il receptor gene therapy can be one of the treatment method for osteosarcoma in the future.

Porcine reproductive and respiratory syndrome (PRRS) is recognized as one of the most important infectious diseases causing serious economic loss in the swine industry worldwide. Due to its increasing genetic diversity, a rapid and accurate diagnosis is critical for PRRS control. The immunochromatographic strip test (ICST) is a rapid and convenient type of immunoassay. In this study, an on-site immunochromatographic assay-based diagnostic method was developed for detection of PRRS virus (PRRSV)-specific antibodies. The method utilized colloidal gold nanoparticle-labeled dual-type nucleocapsid proteins encoded by open reading frame 7. We evaluated 991 field samples from pig farms and 66 serum samples from experimentally PRRSV-inoculated pigs. Based on true PRRSV-specific antibody-positive or
