TEL2 gene cooperates with MYC gene to provoke B-cell lymphomas

The genes TEL2 and MYC cooperate with each other to promote ... MCB report. The TEL2 gene is part of a family of genes called ETS transcription factors. Transcription factors prompt the cell to read the code of a specif...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

Amidst the hoopla over the exact number of genes we have in our genome—more than a fruitfly, fewer ...ften been obscured. The expression of 20,000?0,000 genes is under the control of an uncounted host of non-coding sequences, which bind transcription factors ...

UF Researchers Map Bacterial Proteins That Cause Tooth Loss

...and antibodies. They can also cause disease. “The genes themselves are only important in that they encode the proteins,?Lamont said. “It’s the proteins that are most responsible for disease, and in most cases it’s proteins that are vaccine and drug targets.?/p> The scientists have been trying to under...
