How does the antitumor drug get to the cell nucleus?

Platinum complexes such as the well-known cisplatin are powerful antitumor medications. They cross the cell membrane and reach the nucleus, where they attach to DNA and stop cell growth. But how does cisplatin get to the nucleus Italian researchers have now proven that a copper transport protein may play a critical role.

Link between growth of blood vessels critical to spread of cancer and copper in our bodies

Growing new blood vessels from existing ones - a process called angiogenesis - is important in growth, development and wound healing. But it also enables the spread of tumors throughout the body, so researchers have been scrambling for ways to stop angiogenesis in the fight against cancer.

Bright quantum dots help basic cancer biology studies

Though there is little doubt that nanoscale devices are going to play a critical role in improving cancer detection and treatment over the next five to ten years, nanoparticles are already having a major impact on the way that cancer biologists study the processes that go awry within malignant and metastatic cells.
