Research Abstract

The aim of the present research work is to develop new cancer markers for the daily diagnosis of malignancy based on so far discovered new-characters of cancerous cells, as follow ; (1) most malignant tumor cells have more unstable nuclear DNA than comparable benign tumor cells and normal-cells, (2) malignant tumor cells bear a common cytoplasmic glycoprotein stainable with STA by lectin histochemistry, and (3) malignant cells leberate massive activeoxygens. Acid hydrolysis with 2N HCI at 30゚C forls min after RNase treatment was found to induce selective DNA denaturation of cancer cells in ordinary paraffin-embedded sections, and the single-stranded DN, A was differentially stained immunohistochemically with anti-singlestranded polyclonal antibody. The cDNA. libray of human thyroid cancer was incorporated to E. coli, and the CDNA for STA-positive-glycoprotein and STA-positive mutant B. coli clones-were obtained, and the poly-clonal antibody against for the glycoprotein was also obtained. By using the CDNA and antibody, differential staining of malignant tumor cells was successfully attained by in-situ-hybridization or immunohistochemistry, respectively. The liberation of active oxygen was detected from a Sransplanted squamous cell carcinoma cells of mouse by a photon-counting imaging system (VIM, Hamamatsu Photnics) using a chemiluminescence sensitizer MCLA. Especially the former two methods can be readily used for daily pathological diagnosis of malignancy as reliable cancdr markers.
