Anti-inflammatory approach suppresses cancer metastasis in animal models

An anti-inflammatory drug called ketorolac, given before surgery, can promote long-term survival in animal models of cancer metastasis, a team of scientists has found. The research suggests that flanking chemotherapy with ketorolac or similar drugs -- an approach that is distinct from previous anti-inflammatory cancer prevention efforts -- can unleash anti-tumor immunity. The findings, published in Journal of Clinical Investigation, also provide a mechanistic explanation for the anti-metastatic effects of ketorolac, previously observed in human Read more

I3 Venture awards info

Emory is full of fledgling biomedical proto-companies. Some of them are actual corporations with employees, while others are ideas that need a push to get them to that point. Along with the companies highlighted by the Emory Biotech Consulting Club, Dean Sukhatme’s recent announcement of five I3 Venture research awards gives more examples of early stage research projects with commercial potential. This is the third round of the I3 awards; the first two were Wow! Read more

Take heart, Goldilocks -- and get more sleep

Sleeping too little or too much increases the risk of cardiovascular events and death in those with coronary artery disease, according to a new paper from Emory Clinical Cardiovascular Research Institute. Others have observed a similar U-shaped risk curve in the general population, with respect to sleep duration. The new study, published in American Journal of Cardiology, extends the finding to people who were being evaluated for coronary artery disease. Arshed Quyyumi, MD and colleagues analyzed Read more

Cancer immunotherapy, meet chimera

In Greek mythology, the chimera was a monstrous fire-breathing creature composed of the parts of three animals: a lion, a snake and a goat.

Adoptive cell transfer is advancing as a cancer immunotherapy technique. It involves removing some of a patient’s immune cells, culturing them in the laboratory, and then infusing the cells back into the patient. The idea is to enhance the ability of the immune cells to attack the tumors far beyond what the immune system was able of doing on its own.

Two promising examples are the National Cancer Institute’s approach of treating advanced melanoma with IL-2-stimulated immune cells, and several investigators’ approach of genetically engineering T cells to attack leukemias or lymphomas.

Jacques Galipeau and colleagues at Winship Cancer Institute have developed a chimeric molecule for stimulating immune cells, which appears to have unique powers beyond simply the sum of its two parts. The molecule is called GIFT4, a fusion of the immune signaling molecules GM-CSF (often used in cancer treatment) and IL-4.
