Mechanism of Gemcitabine Resistance in Pancreatic Cancer Chemotherapy / 中国普外基础与临床杂志

ABSTRACT

Objective To investigate the possible mechanism of gemcitabine resistance in pancreatic cancer chemotherapy. Methods Recent literatures about the genes and signal pathways those play key roles in mediating gemcitabine chemotherapy resistance of pancreatic cancer were collected and reviewed.Results Oncogenes like c-Src and bcl-X-L, inflammation pathway of NF-?B, cytokines like IL-1? and NO are closely related with the chemoresistance; the relationship between multiple drug resistance relevant genes like MDR1/P-gP and the resistance to gemcitabine remains to be clarified. Conclusion Genes and pathways like c-Src, bcl-X-L, NF-?B, etc. might become new targets to increase the chemotherapeutic sensitivity of pancreatic cancer, however, the mechanism of pancreatic cancer chemotherapy resistance still needs further to be studied.
