Pancreatic cancer is one of the most common types of cancers in the whole world with a poor prognosis. Finding out how the cancer form and develop is the most important way to cure this cancer. miRNAs, 21–22 nucleotides regulatory small non-coding RNAs, have been found to be critical involved in the growth of pancreatic cancer. In this study, we found that miR-92a was up regulated in three kinds of human pancreatic cancer cell lines. There is a correlation between miR-92a and malignant degree of human pancreatic cancer cell lines. Then we found that miR-92a was essential for promoting cell proliferation in human pancreatic cancer. Inhibition of the function of miR-92a repressed the proliferation of pancreatic cancer cells. Further, we found that miR-92a enhanced the activation of JNK signalling pathway by directly targeting the JNK signalling inhibitor DUSP10. DUSP10 is responsible for miR-92a induced JNK signalling and cell proliferation. Altogether, our study showed a miR-92a/DUSP10/JNK signalling pathway that plays an important role in regulating the proliferation of pancreatic cancer cells.
