Abstract:
Reactive oxidative species (ROS) is a crucial factor in the regulation of cellular biological activity and function, and aberrant levels of ROS can contribute to the development of a variety of diseases, particularly cancer. Numerous discoveries have affirmed that this process is strongly associated with "programmed cell death (PCD)," which refers to the suicide protection mechanism initiated by cells in response to external stimuli, such as apoptosis, autophagy, ferroptosis, etc. Research has demonstrated that ROS-induced PCD is crucial for the development of hepatocellular carcinoma (HCC). These activities serve a dual function in both facilitating and inhibiting cancer, suggesting the existence of a delicate balance within healthy cells that can be disrupted by the abnormal generation of reactive oxygen species (ROS), thereby influencing the eventual advancement or regression of a tumor. In this review, we summarize how ROS regulates PCD to influence the tumorigenesis and progression of HCC. Studying how ROS-induced PCD affects the progression of HCC at a molecular level can help develop better prevention and treatment methods and facilitate the design of more effective preventative and therapeutic strategies.
Insights
Reactive oxygen species (ROS) regulate programmed cell death (PCD), influencing cancer development. Understanding ROS-induced PCD in hepatocellular carcinoma (HCC) is key for new treatments.
Area of Science:
- Biochemistry
- Cell Biology
- Oncology
Background:
- Reactive oxygen species (ROS) are vital for cellular functions.
- Abnormal ROS levels are linked to diseases, especially cancer.
- Programmed cell death (PCD) pathways like apoptosis, autophagy, and ferroptosis are crucial in disease.
- ROS-induced PCD plays a significant role in hepatocellular carcinoma (HCC) development.
Purpose of the Study:
- To review the regulatory role of ROS in PCD.
- To elucidate how ROS-induced PCD influences tumorigenesis and progression of HCC.
- To highlight the molecular mechanisms involved in ROS-mediated PCD in HCC.
Main Methods:
- Literature review of existing research on ROS and PCD in HCC.
- Analysis of molecular pathways linking ROS, PCD, and cancer.
- Synthesis of findings to understand the dual role of ROS in cancer progression.
Main Results:
- ROS act as a double-edged sword, both promoting and inhibiting cancer.
- A delicate balance of ROS is essential for cellular homeostasis.
- Disruption of this balance by aberrant ROS generation impacts tumor growth.
- ROS-induced PCD is a critical factor in HCC pathogenesis.
Conclusions:
- Understanding ROS-regulated PCD is crucial for HCC prevention and treatment.
- Targeting ROS-induced PCD pathways may offer novel therapeutic strategies for HCC.
- Further molecular-level studies can lead to more effective preventative and therapeutic interventions for HCC.

Overview of Cell Death
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the...
