...s theextracellular matrix, or scaffolding, of most mammalian tissues. Untilnow, there has been no practical way to evaluate the daunting number ofpossible combinations of these proteins, any one of which could formthe optimal "niche" for a desired type of differentiated cell.In their experiments, the UCSD rese...

An HIV Protein Plays a Surprising Role in Gene Activation

... complex lacks the TAFs typically linked to TBP in mammalian cells. Because their experiments analyzed only transcription complex assembly, the authors are careful to note that Tat may well stimulate assembly in addition to promoting transcription elongation. And it may be this resourcefulness that makes Tat s...

Spider Venom Could Yield Eco-Friendly Insecticides

Insect pests destroy about 25 percent of the world's crops each year, despite the extensive application of chemical insecticides since World War II. The ...

Plant hemoglobins: Oxygen handlers critical for nitrogen fixation

...that is conceptually not unlike that undertaken by mammalian hemoglobins in facilitating oxygen transport and exchange in the blood. The most conspicuous plant hemoglobins are the symbiotic hemoglobins of legumes; these hemoglobins accumulate in root nodules and give these specialized organs their distinctive...

Scientists identify molecule that regulates well-known tumor suppressor

...lecule DJ-1 as a PTEN suppressor. In studies with mammalian cells, low levels of DJ-1 correlated with decreased PKB/Akt activity, while increased DJ-1 led to activation of PKB/Akt and enhanced cell survival. In cancer cells from breast cancer patients, elevated PKB/Akt activity and reduced PTEN expression wer...
