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.

Hairpin peptide mimetics show promise as new drugs to fight HIV

When a host cell is infected with HIV, the virus brings its own genetic material into the host cell. This cell then replicates, reads the viral RNA, and uses it as a blueprint to produce more viral proteins.

Chemical peroxynitrite tolerates pain

The repeated use of opiate drugs such as morphine to relieve chronic pain results in individuals having to take higher and higher doses of the drug to achieve equivalent pain relief (they are said to exhibit antinociceptive tolerance).

SENP1 protein may provide a basis for future targeted cancer therapies

Researchers at the University of Texas M. D. Anderson Cancer Center have found a protein that enables cellular survival during periods of low oxygen, or hypoxia, which also is key for development of many kinds of cancer.
