DNA sequence controls expression of gene involved in cancer
...h or apoptosis. This protein keeps death-promoting factors
from producing holes in the mitochondria which can result in calcium and destructive proteins leaking out into the cell. However, the overexpression of bcl-2 in damaged cells can lead to the continued division of the mutated cells and eventually canc...
Commandeering cellular machinery: recognition mechanism to detect small molecules
...clear receptors are ligand-activated transcription factors
contained in cells. When activated by specific small molecules, the nuclear receptors initiate a complex process that results in gene expression. Because these receptors play a vital role in controlling cellular response to these small molecules, sc...

they secrete. In developing its consensus, the society focused on three main areas, with separate sessions addressing each. Leading discussions that addressed the biology of the cells was Patricia Zuk, Ph.D., research director, Regenerative Bio...
Is Interleukin-6 the 'holy grail' of exercise mediation?
...arance of IL-6 into circulation depends on several factors
including exercise intensity, duration and mode. For instance, vigorous rowing doubles the amount of IL-6 in plasma relatively quickly, while in endurance activity IL-6 doesn't appear until later. Activation of the IL-6 gene seems to be enhanced when...

often control more than one gene, we believe the absence of dimA may be interfering with an unknown recognition pathway that is essential for spore selection." The results are the first published by a unique Rice-Baylor collaborative that won $5 mill...
