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

Emory team part of undiagnosed conditions challenge

An Emory team of geneticists and genetics counselors is participating in the Clarity Undiagnosed competition, hosted by Boston Children’s Hospital and Harvard Medical School.

The team is led by genetics counselor Dawn Laney MS, CGC, CCRC. Team members include: Madhuri Hegde, PhD, William Wilcox, MD,PhD, Michael Gambello, MD, PhD, Rani Singh, PhD, RD, Suma Shankar, MD, PhD, Alekhya Narravula, MS,CGC, Kristin Cornell, MS, CRC, Cristina da Silva, MS, Sarah Richards, MS, CGC and Kimberly Lewis, MS, CGC.

In Clarity Undiagnosed, five families of patients with undiagnosed conditions provide DNA sequence information and clinical summaries to up to 30 competing teams. The teams then do their best to interpret the data and provide answers, and a $25,000 prize will go to the team that solves the mysteries in the most complete way.

At the discretion of the families, short videos of the patients may be available to investigators through producers of a forthcoming documentary film, Undiagnosed, but the teams are barred from direct interaction with the families. A glimpse of some of the families is possible by viewing the trailer. Teams have until September 21 to submit their reports and the results of the competition will be announced in November.

Boston Children’s and Harvard held a similar competition in 2012, which attracted teams from all over the world.

The competition grows out of the NIH-sponsored Undiagnosed Diseases Network; Emory pharmacologists Stephen Traynelis and Hongjie Yuan have been working with the related Undiagnosed Diseases Program based at NIH (very complex 2014 paper, blog post on personalized molecular medicine).

Supreme decision on DNA patents

In these days of political polarization, how often does the United States Supreme Court make a unanimous decision? When the case has to do with human genes and their patentability!

The case concerned patents held by Utah firm Myriad Genetics on the BRCA1 and 2 genes. Mutations in those genes confer an increased risk of breast and ovarian cancer. The patents in dispute claimed the genes themselves rather than just the technology for reading them.

Cecelia Bellcross, director of Emory’s genetics counseling program and an expert on breast cancer genetics counseling, reports that “in general, the clinical genetics community is jumping up and down, as are a lot of genetics lab directors and definitely patient advocacy groups.”

Myriad’s BRCA tests cost more than $3,000. Several competing firms announced that they would offer tests for the BRCA1 and 2 mutations at significantly lower prices.
