Dr. Zhow Liu goes on cancer research in Huston- PAU inglés 2010

cancer research
After suffering the loss of his two-year old niece to leukemia, cancer had become very personal to Zhow Liu. Then a 15-year old growing up in Indonesia, he decided to make a difference in cancer research. Now in Huston, Dr. Liu has made an important discovery.
In short, his research has described how to destroy two aspects of cancer that make it so deadly. At the same time, he has identified why it can be so difficult to treat.
DNA stores genetic information and messenger RNA carries the template that translates genes into proteins. Two of these proteins are known to make cancer cells aggressive: the "arC" protein, which is implicated in the rapid growth of cancer cells, and the "agcP" protein, which blocks the effectiveness of treatments such as chemotherapy. Basically, cancer cells produce too many of both proteins. Dr. Liu's research is trying to understand how to control the RNAs that lead to the production of "arC" and "agcP" proteins in cancer cells.
"We're really excited with what we have discovered, especially when you consider that this research mostly involved students and it was done entirely in Huston," adds Dr. Liu. "There are only three other cancer research teams in the world looking at the same proteins as we are, and those groups are in the UK, Spain, and Denmark."
Despite the discovery, Dr. Liu is quick to point out that "a cure for cancer isn't right around the corner." These things take years. "We think we've made a significant contribution, but our findings can only be demonstrated in a test tube, not in the body - at least not yet. If we continue having success with our research, we'll eventually test our hypotheses in actual cancer cells."
Dr. Liu remains focused on making a difference in cancer research. "I made a vow 25 years ago, and I'm as committed as ever."
