Pancreatic cancer. Fluorescence light micrograph of mitochondrial dynamics in pancreatic cancer tissue. The mitochondrial staining is in red, with cell nuclei stained in blue. The tissue structure is of abnormal pancreatic ducts from a mouse, which is being used to model pancreatic ductal carcinoma in humans. Changes in the shape of the mitochondria occur throughout the progression of pancreatic cancer. It is thought that the mechanism that regulates the dynamics of mitochondria may be a promising new therapeutic target in the fight against this disease.
