The continuing growth in knowledge of cellular mechanisms - and capabilities in bioinformatics - has certainly been paying off in cancer research over the past few years - good news for the future of healthy life extension, as cancer is big concern. Many potential cures are currently in the works. InfoAging reports on yet another promising new approach: "Scientists have fixed a defect in cancer cells that allows them to avoid the normal cell-death process, and as a consequence, they eliminated leukemia cells from laboratory mice. ... BCL-2 overexpression has been noted in many types of cancer, and was first found in lymphoma cells. ... This study provides strong support for the speculation that blocking BCL-2 would be lethal to cancer cells."
