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.

Hepatitis C virus found to spread directly from cell to cell by-passing antibodies

Scientists looking for an effective treatment for Hepatitis C may face an even bigger task than anticipated. Recent studies looking into how the virus spreads in liver tumour cells have demonstrated that the virus uses two different routes, which may explain why the body's natural occurring antibodies are ineffective at controlling the virus.
