Pancreatic ductal adenocarcinoma (PDAC) is the most predominant type of pancreatic cancer and presents one of the highest mortality rates when compared with other carcinomas. The absence of efficient treatment options for PDAC prompted us to investigate whether microRNA inhibition, combined or not with chemotherapeutic agents, would constitute a promising therapeutic approach for this disease. In this chapter, we describe several methods and procedures that can be used to evaluate the potential of new therapeutic strategies involving oligonucleotides against overexpressed microRNAs, in PDAC, either alone or in combination with low amounts of chemotherapeutic drugs.
