Sixteen longSAGE libraries from four different clinical stages of cervical intraepithelial neoplasia have enabled us to identify novel cell-surface biomarkers indicative of CIN stage. By comparing gene expression profi les of cervical tissue at early and advanced stages of CIN, several genes are identifi ed to be novel genetic markers. We present fi fty-six cell-surface gene products differentially expressed during progression of CIN. These cell surface proteins are being examined to establish their capacity for optical contrast agent binding. Contrast agent visualization will allow real-time assessment of the physiological state of the disease process bringing vast benefi t to cancer care. The data discussed in this publication have been submitted to NCBIs Gene Expression Omnibus (GEO, http://www.ncbi.nlm.nih.gov/geo/) and are accessible through GEO Series accession number GSE6252.
Using LongSAGE to Detect Biomarkers of Cervical Cancer Potentially Amenable to Optical Contrast Agent Labelling

The performance of a recently developed real-time PCR system, the ExiStation HBV diagnostic system, for quantitation of hepatitis B virus (HBV) in human blood was evaluated. The detection limit, reproducibility, cross-reactivity, and interference were evaluated as measures of analytical performance. For the comparison study, 100 HBV-positive blood samples and 100 HBV-negative samples from Korean Blood Bank Serum were used, and the results of the ExiStation HBV system showed good correlation with those obtained using the Cobas TaqMan (r 2 = 0.9931) and Abbott real-time PCR systems (r 2 = 0.9894). The lower limit of detection was measured as 9.55 IU/mL using WHO standards and the dynamic range was linear from 6.68 to 6.68 × 10 9 IU/mL using cloned plasmids. The within-run coefficient of variation (CV) was 9.4%, 2.1%, and 1.1%, and the total CV was 11.8%, 3.6%, and 1.7% at a concentration of 1.92 log 10 IU/mL, 3.88 log 10 IU/mL, and 6.84 log 10 IU/mL, respectively. No cross-reactivity or interference was detected. The ExiStation HBV diagnostic system showed satisfactory analytical sensitivity, excellent reproducibility, no cross-reactivity, no interference, and high agreement with the Cobas TaqMan and Abbott real-time PCR systems, and is therefore a useful tool for the detection and monitoring of HBV infection.
Performance evaluation of ExiStation HBV diagnostic system for hepatitis B virus DNA quantitation

Porcine transmissible gastroenteritis virus (TGEV) and porcine epidemic diarrhea virus (PDEV) can cause severe diarrhea in pigs. Development of effective vaccines against TGEV and PEDV is one of important prevention measures. The spike (S) protein is the surface glycoprotein of TGEV and PEDV, which can induce specific neutralization antibodies and is a candidate antigen for vaccination attempts. In this study, the open reading frames of the TGEV S1 protein and in addition of the S or S1 proteins of PEDV were inserted into the eukaryotic expression vector, pIRES, resulting in recombinant plasmids, pIRES-(TGEV-S1-PEDV-S1) and pIRES-(TGEV-S1-PEDV-S). Subsequently, 6-8 weeks old Kunming mice were inoculated with both DNA plasmids. Lymphocyte proliferation assay, virus neutralization assay, IFN-c assay and CTL activity assay were performed. TGEV/PEDV specific antibody responses as well as kinetic changes of T lymphocyte subgroups of the immunized mice were analyzed. The results showed that the recombinant DNA plasmids increased the proliferation of T lymphocytes and the number of CD4+ and CD8+ T lymphocyte subgroups. In addition, the DNA vaccines induced a high level of IFN-c in the immunized mice. The specific CTL activity in the pIRES-(TGEV-S1-PEDV-S) group became significant at 42 days postimmunization. At 35 days post-immunization, the recombinant DNA plasmids bearing full-length S genes of TGEV and PEDV stimulated higher levels of specific antibodies and neutralizing antibodies in immunized mice.
