Image: In a recent study, CRISPR gene editing was shown to halt the progression of Duchenne muscular dystrophy (DMD) in dogs. The photomicrographs show dystrophin (in green) in a healthy diaphragm muscle (left), absence of dystrophin in a dog with DMD (center), and restoration of dystrophin in dogs treated with CRISPR (right) (Photo courtesy of the University of Texas Southwestern Medical Center).

Gene Editing Reverses DMD Muscle Damage in Model

The CRISPR/Cas9 genome-editing tool was used in a proof-of-concept study conducted in dogs suggested that the technique could be clinically useful for the treatment of Duchenne muscular dystrophy. More...

Image: The role of miRNAs in inflammatory bowel disease (IBD): miR-29 loaded on a supercarbonate apatite prevented the development of inflammation by suppressing the production of inflammatory cytokines (IL-6, TGF-beta, and IL-23) secreted from dendritic cells and by suppressing the differentiation of naive T-cells to Th17 cells (Photo courtesy of Osaka University).

Nucleic Acid Therapy Effective in Inflammatory Bowel Disease Model

A team of Japanese researchers working with a mouse model recently described a novel method for using microRNAs to treat inflammatory bowel disease (IBD). More...

Teratomas Offer Source for Rebuilding Damaged Tissues

Muscle stem cells, which were derived from benign teratoma tumors, were found to demonstrate exceptional potential as starting material for rebuilding and maintaining damaged muscle tissues. More...

Use of gene editing to cut DNA at a precise location reduced autism symptoms in mice with fragile X syndrome (Photo courtesy of the University of California, Berkeley).

CRISPR/Cas9 Corrects Symptoms of Fragile X Syndrome in Model

In order to correct fragile X syndrome in a mouse model, a team of neurological disease researchers used gold nanoparticles rather than viruses to deliver the CRISP\Cas9 gene-editing tool to cells in striatum, a brain region associated with formation of habits. More...
