In order to provide insight into the biological behavior of pancreatic cancer and identify new potential biomarkers, we have in the past few years initiated a study aiming to examine the levels of HDAC and SIRT genes expression in a set of surgically resected pancreatic tissues including 11 pancreatic adenocarcinoma samples and a normal pancreas tissue. The gene discussed is HDAC9; the disease is pancreatic neoplasm.
