Traditional biochemical methods of studying human gene mutations are often laborious and costly. Now bioengineers at the University of California San Diego have developed a new simple approach to rapidly check on human gene changes and also screen chemicals as potential drugs by turning everyday bacteria into living test tubes.
The researchers published their new study in the April 30 issue of Nature Biomedical Engineering.
Human cells carry thousands of genes, and tiny changes in these genes can cause serious diseases. Usually, scientists study these changes by testing proteins in a test tube or in human cells. But those methods can be slow, expensive and sometimes hard to do.
