Abstract:
Malignant tumors are characterized by irregular boundaries, rapid and uncontrolled cell growth, the ability to invade surrounding tissues, and the potential to spread and metastasize to other parts of the body through the bloodstream or lymphatic system. More than 90 % of cancer-related deaths are attributed to the metastasis of cancer cells. When malignant tumors metastasize, the metabolic processes within the cells undergo significant changes, with enzymes playing a crucial role in regulating metabolism and serving as key mediators in both synthesis and degradation. Oxygenases are a group of oxidative enzymes that catalyze the incorporation of oxygen atoms into various substrates. Advances in our understanding of the genome and proteome of malignant tumors have revealed that oxygenases are highly expressed in many metastatic tumor cells, where they can enhance the activity of specific proteins that regulate tumor metastasis. Furthermore, there is a growing recognition that certain drugs can specifically target oxygenases to inhibit tumor metastasis, with several of these agents are currently undergoing clinical evaluation. In this context, we summarize the mechanisms by which oxygenases influence cancer cell behavior, along with the preclinical and clinical studies related to targeted therapies involving oxygenases.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
