Outline of Final Research Achievements |
Gemcitabine (Gem) is widely used for chemotherapy for pancreatic cancer, but the effect is not fully satisfactory, and the reason is resistance. We succeeded in establishing a Gem-resistant pancreatic cancer cell line and confirmed that the expression of CXCR4, a cancer stem cell marker, is enhanced along with resistance with DNA microarray. We also found that CXCR4 is involved in the proliferation and infiltration of Gem-resistant pancreatic cancer via cancer stromal interaction, which was confirmed to be suppressed by control of CXCR4 signal such as CXCR4 antagonist. Based on the above findings, we found a new finding that control of CXCR4 is a target for novel therapeutic drugs in Gem-resistant pancreatic cancer.
