Abstract
Cell death in the living system plays a vital role in maintaining the homeostasis and balancing the cell count in the body. Programmed cell death (PCD) is a crucial component of several development and defense mechanisms. PCD is also important in terms of aging which avoids the accumulation of cellular damage by maintaining cell division. Depending on the execution of cell death and its role in destruction, PCD is categorized into several subtypes. The major different forms of PCD in animals are apoptosis, autophagy and necrosis, which can be distinct in morphological terms. More intense investigations of cell death have given close insight showing other important types of cellular destruction and their pivotal roles in treating disease conditions like cancer. Flavonoids have been acquired a great interest for disease therapies and chemoprevention through activation of several PCD mechanisms. The significant potential of natural flavonoids in the induction of distinct signaling cascades is being a massive approach for targeting uncontrolled cell growth. For these reasons, understanding PCD mechanisms is a promising approach for the interventions in treating cancer. Thus, it is intriguing that understanding the different forms of PCD mechanism induced by flavonoids with more accurate descriptions on the biochemical and cellular processes are gaining more significance in cancer research. Here, we provide a brief overview on the different types of PCD and aim to discuss the functional role of flavonoids in promoting different types of cell death as well as an extensive brief review on their mechanism of action has been highlighted.
