Work may help increase use of gene therapy in disease treatment

快猫成版视频 researcher Daniel Morris recently received a three-year $403,000 grant from the National Institutes of Health to improve the delivery of protein therapeutics and the CRISPR/Cas gene-editing technology to living cells.

CRISPR (Clustered Regularly Interspaced Short Palindromic Repeats)/Cas is a rudimentary immune system found in bacteria that protects the bacteria by saving a piece of the invading viral gene to detect future infections. This gene-editing technology has been adapted for use in gene therapy because of its accurate manipulation of genetic material.

Morris, associate research professor of biology, explained that gene modification can be difficult in tissues and organs of living patients because current practices of delivering the gene-editing technology such as CRISPR/Cas are limited in scope. Usually the cell-penetrating peptides (CPPs) responsible for carrying the cargo of gene-edited DNA or protein therapeutics can get trapped in undesired locations of the cell.

His research is focused on attaching a CPP-adaptor protein to the cargo of the critical DNA or protein therapeutics. Upon entering the cell membrane, the CPP-adaptor protein would release the cargo into the cell interior before getting trapped in an undesirable location.    

鈥淲ith general utility and low toxicity, CPPs are a potentially transformative technology,鈥� Morris said. 鈥淭his NIH grant will not only help significantly expand the utility of the CRISPR/Cas gene editing technology in gene therapy, but also validate that our CPP technology is an adaptable tool for delivery of a wide array of macromolecules, potentially improving the delivery of biomolecular therapeutics to treat a variety of disorders.鈥�

鈥淲e were fortunate to be able to attract a researcher of Dr. Morris鈥� stature to KSU. He brings a rigorous but innovative perspective to our work,鈥� added Jonathan McMurry, associate vice president for research, who collaborates often with Morris on other projects.
