Regarding the mechanisms of cancer, which of the following statements is NOT correct? Ovarian cancer is always the result of hypomethylation of tumor suppression genes Unlike normal human cells that can divide between 50-70 times, tumor cells can divide indefinitely Sirtuins are enzymes linked with longevity that increase in activity in response to resveratrol supplementation Many tumors are able to grow their own blood supply by forming new branches from nearby blood vessels
