| Outline of Final Research Achievements |
Evaluation of the biological significance of pXY molecule in pancreatic cancer cells revealed that pXY molecule was strongly involved in cell survival, and that pXY contributed to maintenance of intracellular antioxidant capacity and detoxification ability, and that reduced the easy-cytotoxicity by inhibiting FasL/Fas ligand. The secretion of pXY from the cells into the culture medium was detected by conventional ELISA method, whereas there remained a problem with the detectable limit concentration of pXY in blood by the present ELISA method. These results indicated that a novel antibody with higher sensitivity to pXY is required to achive the pXY detection in blood.
