Array-based hybridization and the serial analysis of gene expression (SAGE) are the most common approaches for high-throughput transcript analysis. Each has advantages and disadvantages. The cDNA array allows rapid screening of a large number of samples but cannot detect unknown genes. In contrast, SAGE can detect those unknown genes or transcripts but is(More)
 The HBV in the sera of two chronic active hepatitis patients were analyzed for the promoter sequence heterogeneity. In most cases, the proportion of any particular clone in the total viral populations was less than 50%, showing high mutation rates. In contrast, promoter sequences of HBV from asymptomatic carriers revealed only a few point mutations with no(More)
A membrane glycoprotein CD4 functions as a co-receptor of a T lymphocyte. The co-receptor function has been attributed to a protein tyrosine kinase, p56lck, which is activated upon CD4 binding to MHC molecule. In this study, we present evidences that one of the pathways through which CD4 transmits its signal is cytoskeleton association of p56lck tyrosine(More)
In an attempt to understand the molecular bases of gastric cancer progression, we have analyzed the differentially expressed genes in gastric cancer by SAGE. Four SAGE cDNA tag libraries were constructed from two sets of gastric cancer and normal tissues and 241,127 tags were obtained. By comparing the tags from cancer and normal tissues, 414 differentially(More)
Sequence analysis of antibody variable (V) regions can provide an insight regarding whether B cells have gone through an antigen-driven process of affinity maturation. In this study, we analyzed 16 V-regions of immunoglobulin (Ig) kappa light chain genes obtained from a cDNA library of a rheumatoid arthritis (RA) synovial tissue. A salient feature of our(More)
Hepatitis B viral (HBV) infection in early childhood is one of the leading causes of chronic hepatitis and liver cirrhosis that eventually lead to hepatic carcinoma. Despite the nationwide immunization programs to curtail the vertical transmission of HBV, childhood HBV infection through mothers is still occurring in Korea. As one of the efforts to(More)
