| 英文摘要: |
| Pancreatic cancer is one of the most poor prognosis tumors. A primary cause for this is that pancreatic adenocarcinoma
has no noticeable sign or symptoms at the early stage, and no effective medicine has been found for the tumor yet. At present, there is no
suitable examination to screen pancreatic cancer at the early stage without injury. So, it is very important to find methods for the early diagnosis
and treatment of pancreatic cancer. In recent years, SELEX(systematic evolution of ligands by exponential enrichment) technology
has provided a new method for the early diagnosis of pancreatic cancer on the basis of valuable applications in other cancers. This technology
can screen aptamers which specificly bind to molecular targets of the pancreatic cancer for the pathogenesis. Then, the further
chemical modification for those aptamers may turn the target, molecular level imaging, early diagnosis, targeted therapy and early treatment,
to be true. This has a great significance. This article will review the progress and application of SELEX technology in molecular diagnosis
and targeted therapy of pancreatic cancer. |
