PRAN touts recent WSJ write-up disputing importance of amyloid in Alzheimer’s:
[The WSJ reference is to the provocative Alzheimer’s column by Sharon Begley which ran last Friday. A follow-up column is scheduled for this coming Friday’s WSJ. However, today’s PRAN’s PR (below) seems to play this issue both ways, and strikes me as somewhat disingenuous.]
>> Wall Street Journal Article Profiles Challenges for Alternative Alzheimer's Researchers
MELBOURNE, Australia, April 12 /PRNewswire-FirstCall/ -- Australian drug development company Prana Biotechnology Limited (Nasdaq: PRAN) announced today that an important article appearing in the April 9th, 2004 edition of The Wall Street Journal has shed further light on the difficulties facing researchers of Alzheimer's Disease that differ from the prevailing "amyloid hypothesis."
The story serves as a follow-up to a feature profile of Prana Biotechnology's Chief Scientist Professor Ashley I. Bush, M.D., Ph.D., of Harvard Medical School, which ran in The Wall Street Journal on December 26, 2003. In that article, Dr. Bush discussed his many challenges in gaining peer acceptance of his theories. His revolutionary work on brain zinc and copper interactions causing amyloid pathology was eventually recognized by his peers last year when he received the prestigious Potamkin Prize from the American Academy of Neurology. This work is the scientific platform behind Prana's MPAC drug class, which showed benefit in a phase 2 clinical trial published last year.
The current article chronicles another Harvard Medical School team, that was able to shut down two mouse genes whose human forms have been linked to inherited forms of Alzheimer's. Against the advice of the lead researcher's mentor, the scientists submitted their findings to two leading journals, only to face a long list of criticisms that took months to address. "Powerful people in this field think that amyloid causes Alzheimer's and won't consider research that questions the amyloid hypothesis," said one of the Harvard scientists. In total, the publication of this potentially important paper was delayed nearly two years.
The difficulties such researchers face in introducing new theories to the Alzheimer's debate has been gaining in recognition. In the article, Zaven Khachaturian, who ran research at the National Institute of Aging, said, "Whenever you have a field with limited funding, and a small number of people with big egos who have everything invested in one idea, you have the right chemistry for one theory to become so pervasive nothing else can flourish." Khachaturian added that the dominance of the amyloid hypothesis and the strangling of alternatives was "one of the most important issues in science today." <<
