Combination targets: some drugs may work best when they work together

... with a lack of oxygen, a state called hypoxia, they report. AZD6244 is a small molecule inhibitor developed by AstraZeneca to bind to and inhibit mek1 and MEK2 proteins, which together form a critical point on the pathway that controls the ongoing survival of cells. Defects along the pathway can lead...

New Fusion Trans-Activator Plasmids for Studying Signal Transduction Pathways

...ctivates the GAL4-c-Fos fusion protein expressed from the pFA-cFos plasmid. The mechanism of this activation is not yet characterized. PKA, mek1 and other extracellular stimuli failed to activate the GAL4-c-Fos fusion protein (data not shown). ...

Improved Vectors for PathDetect Trans-Reporting Systems

...smids with either the pFC-dbd or pFC2-dbd plasmids yielded similar background levels of luciferase activity. Since the mek1 protein is a known upstream activator of the Elk1 protein, the pFC-MEK1 plasmid was used to compare the activity of the pFA-Elk1 and ...
