Abstract
This opinion article highlights the mechanism of wound healing and the impact of wound on cancer evolution and cancer therapy. Wound healing requires the proliferation and the terminal differentiation (TD) of progenitor stem cells (PSCs). PSCs are pluripotent stem cells capable of undergoing differentiation to become various cells needed for the repair of the wound. Wound healing is deeply influenced by metabolites involved in chemo-surveillance and cachexia. Wound triggers the production of prostaglandins (PGs) which play an essential role to promote the proliferation of PSCs at the initial stage of the wound. At the final stage of wound healing, chemo-surveillance comes into play to induce TD of PSCs. The functionality of chemo-surveillance dictates the success of wound healing. The functionality of chemo-surveillance is usually intact in healthy people, so wounds typically heal nicely without having to put up any efforts. Wound also triggers production of tumor necrosis factor (TNF) which is responsible for the display of cachexia symptoms leading to the collapse of chemo-surveillance. TD of PSCs will be impaired, allowing PSCs to evolve into cancer stem cells (CSCs). It takes only a single hit to silence TET-1 enzyme to convert PSCs to become CSCs, which is well within the reach of PSCs because MEs of PSCs are abnormally active like cancer cells (CCs) due to association with telomerase. Wound healing and evolution of cancer are so closely related to involve PSCs as the critical common elements. Cancer can arise if a wound is not healed properly. The most appropriate strategy for cancer therapy is to follow successful process of wound healing. The appropriate strategy must be able to eliminate cachexia symptoms, to restore the functionality of chemo-surveillance, to eradicate CSCs, to eliminate differentiation blockade, and to put away oncogenes and cancer suppressor genes. Wound healing metabolites are the best candidates to fulfill such requirements.
