Purpose of Review
Although there are significant improvements in diagnosis and therapeutics tools, cancer remained a major cause of deaths in developing and developed countries. Among others, endogenously or exogenously generating reactive oxygen species (ROSs) are considered a crucial cause for tumor initiation, development, and survival. Unhealthy lifestyle, exposure to various carcinogens, ionizing radiations, and chemotherapy drugs are the main factors for ROS production.
Recent Findings
Reactive oxygen species cause genetic instability due to DNA damage or mutation load. Exposer to ROS also modulates the expression of various transcription factors such as Sp1, AP1, and NF-κβ implicated in proliferation, metastasis, and cancer stem cell maintenance. It is suggested that ROSs are involved in various cancer-related process including apoptosis, angiogenesis, metastasis, and inflammation. Numerous data from several studies suggest ROS as one of the therapeutic targets for cancer prevention and cure.
Summary
The current review summarizing the interactions of ROSs with various cellular molecules involved in angiogenesis, metastasis, and inflammation.
