How bureaucracy is killing innovative medical research

 :: Posted by American Biotechnologist on 12-12-2011

The promise of stem cell research for drug discovery and cell-based therapies depends on the ability of scientists to acquire stem cell lines for their research.

A survey of more than 200 human embryonic stem cell researchers in the United States found that nearly four in ten researchers have faced excessive delay in acquiring a human embryonic stem cell line and that more than one-quarter were unable to acquire a line they wanted to study.

“The survey results provide empirical data to support previously anecdotal concerns that delays in acquiring or an inability to acquire certain human embryonic stem cell lines may be hindering stem cell science in the United States,” said Aaron Levine, an assistant professor in the School of Public Policy in the Ivan Allen College of Liberal Arts at the Georgia Institute of Technology.

Results of the survey were published in the December issue of the journal Nature Biotechnology. Funding for the study was provided by the Kauffman Foundation’s Roadmap for an Entrepreneurial Economy Program.

A genetic breakthrough for cleft lip

 :: Posted by American Biotechnologist on 11-29-2011

Scientists at Weill Cornell Medical College used genetic methods to successfully repair cleft lips in mice embryos specially engineered for the study of cleft lip and cleft palate. The research breakthrough may show the way to prevent or treat the conditions in humans.

Cleft lip and cleft palate are among the most common birth defects, with treatment requiring multiple cycles of surgery, speech therapy and orthodontics. To date, there have been very few pre-clinical methods that allow researchers to study the molecular causes of these malformations. In particular, there has been a lack of animal models that accurately reflect the contribution of multiple genes to these congenital deformities in humans.

New technique for watching proteins in action in intact cells

 :: Posted by American Biotechnologist on 11-01-2011

Proteins are literally the movers and the shakers of the intracellular world. If DNA is the film director, then they are the actors. And much can be learned about cell function – and dysfunction – by watching proteins on the move.

Until now, scientists have only been able to see this process indirectly. Now researchers at Vanderbilt University in Nashville, Tenn., have come up with a promising new technique that uses a scanning transmission electron microscope (STEM) to view proteins tagged with gold nanoparticles in whole, intact cells.

Genomes, Phenomes and Personalized Medicine

 :: Posted by American Biotechnologist on 10-26-2011

George Church, who it may be argued is the father of personalized genomics, spoke at TEDMED about the future of personal genomics and what research has yielded so far. Ironically, when he gave this talk one year ago in October of 2010, a google search of the term “synthetic personal genomes” did not yield any results (according to Dr. Church). The same search done today returns over 900,000 results! Obviously George continues to be light years ahead of the crowd. Have a look at the video below and see for yourself.
