Targeting mitochondrial dysfunctions in pancreatic cancer evokes new therapeutic opportunities.

Pancreatic cancer (PC) is a highly devastating neoplasm due to its irrepressible characteristics and propensity to override the available treatment strategies. Rapid prevalence and enormous severity of this cancer urgently demand the exploration of novel approaches for the development of effective therapeutic measures. Metabolic derangement is one of the hallmarks of cancers which restructures mitochondrial activities and biological pathways. Apart from their bioenergetic and biosynthetic functions, mitochondria are also implicated in a myriad of cellular functions including proliferation, differentiation, apoptosis, senescence, homeostasis, and other cell regulatory mechanisms. It has been noted that PC, like other types of cancers, exploits these activities in favor of tumor growth and survival by inducing mitochondrial dysfunctions such as mitochondrial-DNA mutation, metabolic enzyme modification, ROS generation, mitophagy, evasion of apoptosis, and mitochondrial biogenesis. During pancreatic carcinogenesis, a large number of onco-factors including Bcl-2 family proteins, NF-κB, HIFs, NRF2, NOX, MFNs, DRP1, DUSP6, Cyp-D, PARKIN, and others are dysregulated, resulting into reprogramming of metabolic pathways and cellular kinetics. Hence, targeted interventions in these metabolic derangements may present some effective anticancer approaches. The current review gives an insight into various mitochondrial disorders and their targetable molecules in PC which may provide certain novel opportunities in the pursuit of therapeutic development. Furthermore, we have also discussed certain treatment perspectives in PC based on specific mitochondrial activities.
