...U.S. and west of Europe that comprise an above-sea portion of the mostly submerged Mid-Atlantic Ridge. To measure the energy generated by the extraordinarily intense turbulence more than a mile below the oceans surface, St. Laurent and crew used a custom-made instrument called the "turbulence profiler," ou...JCI table of contents: Aug. 9, 2007
...U.1 is a tumor suppressor. Mice lacking a specific portion of the DNA (known as the upstream regulatory element; URE) that controls the level of expression of the PU.1 gene develop acute myeloid leukemia (AML).

This new result shows that COX-2 does not prefer fish oil to vegetable oil. Regardless of the amount of extra fish oil that we added, COX-2 still help...U-M researchers identify gene involved in breast cancer
...d to be either deleted or mutated in a substantial portion of the cancer sample: about 80 percent of the cancer tissues studied did not express the gene at all.
