Phycobiliproteins could have some anti-tumor properties when used on patients suffering from cancer. CPC, C-Phycocyanin, for example, has been shown to stop DNA replication in colon cancer and lung cancer cells; thus, reducing the size of the tumor. CPC is able to induce apoptosis, programmed cell death, in the cancer cells. This is due to CPC’s ability to activate cytochrome C. CPC has also been shown to block the cell cycle in the G0 and G1 phase by blocking DNA synthesis. This can cause cancer cells to lose the ability to rapidly multiply and prevent cancer from spreading. Phycobiliproteins could provide a way to help reduce tumors in patients while also remove the harsh side-effects of other methods that are currently being used to remove tumors and fight cancer. The entire mechanism of how Phycobiliproteins reduce tumors is still unknown and currently being researched.
