Enzyme is crucial for production of plant growth hormone

To identify the enzyme expressed by the YUCCA gene, the scientists did genetic studies and found that the gene resembled FMO genes foun...Cancer-linked BRCA2 gene plays previously unsuspected role in cell division
...s inactivated, their experiments showed, cells are dramatically delayed in their progress through mitosis, the cell-division stage of the cell cycle. The find opens an entirely new line of thinking for researchers working to understand how BRCA2 can cause cancer when mutated.

Following the success of this research, trials in human patients with glaucoma are expected to begin soon.
