Synthesis of Anti-Leukemia Compounds from South Pacific Sponge

Scientists at the Scripps Research Institute have succeeded in synthesizing kapakahines, compounds with anti-leukemia potential that are normally produced in vanishingly small quantities by the South Pacific tube-type sponge Cripbrochalina olemda. With the synthetic process in hand, it will be possible, for the first time, to produce kapakahines in quantities sufficient for thorough study of their effectiveness in combating leukemia.

Origins of Deadly Prostate Cancer Traced to Single Aberrant Cell

The origins of metastatic prostate cancer cells can be traced to a single original cancer cell in individuals. This is the conclusion of a 14-year autopsy-based study of copy number variation in the cells of prostate cancer victims. The study was carried out by researchers at Johns Hopkins and collaborating institutions. The findings call into question current views of the origins of primary prostate cancer and suggest that the genomic profile of prostate cancer metastases should inform therapeutic decisions.
