The long-term research goal of our laboratory is to utilize bioinformatic tools/databases in elucidating molecular and cellular aspects of tumor progression and host-tumor immune responses. Our research efforts are intended to elucidate tumor biology and immunology using bioinformatics data-mining knowledge. Current major projects involve:
PTKs are a major class of oncogenes and may serve as useful biomarkers for human cancers. We have established a RAGE PTK profile method combines the RT-PCR/degenerate-primers approach and the differential display approach. With fluorescent labeled primers and capillary electrophoresis, we have achieved high throughput analysis and better QC and QA performance for detecting PTK expression in human cancers.
Our laboratory has devoting much effort to develop bioinformatic tools for studying gene expression transcripts. Previously, we have used the human dbEST database for the discovery of human genes. We have discovered NAGNAG-based tandem repeat would appear to be the major wobble-splicing InDel isoform observed in EST data-mining. We are examining the detailed wobble-splicing mechanism in cells.
An increasing body of evidence has shown that miRNAs function not only during development but also in disease progression. We have now established a new scanning method using criteria based on the features of known human pre-miRNAs to discriminate miRNAs from random sequences. Currently, we have extended our miRNA discovery pipeline to pathogenic viruses and parasites. We have also engaged in the regulation features of human miRNAs in development and diseases.
