Molecular battle in cancer cells offers clues for treatment
Date:1/19/2011

we can survive it, we know it's not toxic. That gives us a window of opportunity," said Xiong.

"In terms of future therapeutic interventions for IDH-mutated tumors, there are two directions we could go," Xiong said. "One is developing a drug that inhibits the ability of the mutant enzyme from producing 2-HG. Another is to somehow provide ?-KG back to the patients with mutated IDH to battle 2-HG."

Such therapies would help only those cancer patients with IDH mutations. "We no longer believe there will be a single silver bullet, a drug to treat and cure all types of cancers," Xiong said. "Instead, we are looking into the therapeutic treatment of individual types of cancer. Therefore, a specific agent that is targeting a very specific event such as tumor with mutated IDH now becomes much more valuable."

In 2010, more than 13,000 people died from brain and other nervous system cancers, and more than 20,000 died from leukemia. A drug that helps even a portion of patients with these cancers can still affect a lot of people, said Xiong.
