Targeted mitochondrial therapy for pancreatic cancer

Pancreatic cancer (PC) is a highly invasive tumor characterized by delayed diagnosis, rapid progress, and resistance to chemotherapy. Mitochondria, as the "power chamber" of cells, not only play a central role in energy metabolism but also participate in the production of reactive oxygen species (ROS), calcium signaling, regulation, and differentiation of the cell cycle. The abnormal activity of mitochondria is closely related to the development of PC. In this paper, we discussed the key role of mitochondria in PC, including mitochondrial DNA, mitochondrial biogenesis, mitochondrial dynamics, metabolic regulation, ROS generation, and mitochondrial-dependent apoptosis. We elaborated on the importance of these mitochondrial mechanisms in the development of PC and emphasized the potential of targeted mitochondrial therapy strategies for these mechanisms in the treatment of PC. In addition, this article also reviews the latest developments in innovative drug carriers such as cell-penetrating peptides, nucleic acid aptamers, and nanomaterials, which can achieve precise localization of mitochondria and drug delivery. Therefore, this article comprehensively analyzed the important role of mitochondria in the treatment of PC and clarified the effectiveness and necessity of targeting mitochondria in the treatment of PC.
