Korean researchers have developed a new cancer treatment that induces cancer cell to die by themselves.
Professor Shin Deuk-yong (47) of the Dankook University College of Medicine said on June 21 that his research team found that PTX-2 separated from poriferan living in the South Sea selectively kills cancer cells that do not contain the p53 gene that serves to restrain cancer.
The study results budgeted by the Ministry of Science and Technologys program to support government-appointed laboratories was recently published in Oncogene, a renowned medical magazine regarding cancer genes. P53 is a gene that restrains the outbreak of cancer, and without it, normal cells turn into cancer cells. About 60 percent of cancer patients dont have the p53 gene.
The research team injected PTX-2, which blocks the formation of cytoskeleton, into mice, and confirmed that cancer cells that dont have p53 die by themselves without any influence on normal cells.
