An 'on-off switch' for gene editing

Over the past decade, the CRISPR-Cas9 gene editing system has revolutionized genetic engineering, allowing scientists to make targeted changes to organisms’ DNA. While the system could potentially be useful in treating a variety of diseases, CRISPR-Cas9 editing involves cutting DNA strands, leading to permanent changes to the cell’s genetic material. Now, in a paper published online in Cell,…

Metastasis monitoring: CRISPR tool catches cancer 'in the act'

When cancer is confined to one spot in the body, doctors can often treat it with surgery or other therapies. Much of the mortality associated with cancer, however, is due to its tendency to metastasize, sending out seeds of itself that may take root throughout the body. The exact moment of metastasis is fleeting, lost in the millions of divisions that take place in a tumor. “These events are…

    Pancreatic cancer: Genome-wide analysis reveals new strategies

    For some cancers, initial treatment with chemotherapy brings positive, but only temporary, results: tumors shrink, but then rebound as the cancer becomes drug-resistant. This pattern of remission-resistance-relapse is particularly true for pancreatic cancer, an aggressive disease in which early success is often countered by eventual disease progression. To wit: The one-year relative survival rate…
