Head to head narcolepsy/hypersomnia study

At the sleep research meeting in San Antonio this year, there were signs of an impending pharmaceutical arms race in the realm of narcolepsy. The big fish in a small pond, Jazz Pharmaceuticals, was preparing to market its recently FDA-approved medication: Sunosi/solriamfetol. Startup Harmony Biosciences was close behind with pitolisant, already approved in Europe. On the horizon are experimental drugs designed to more precisely target the neuropeptide deficiency in people with classic narcolepsy type 1 Read more

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

Growth factor mimics promote recovery after nerve injury

Peripheral nerve injury ranges from chronic irritation like carpal tunnel syndrome to violent trauma. Severe nerve injury can leave patients with lifelong disabilities. Even if nerves regenerate, functional recovery is often poor, because of problems with regeneration of axons, the signal-carrying “stalks” of nerve cells.Figure4.axons

Cell biologist Art English and his colleagues have shown that compounds identified by pathologist Keqiang Ye can promote axon regeneration when mice have injured peripheral nerves. The growth Cheap NFL Jerseys factor-mimicking compounds not only stimulate axons to regenerate twice as quickly (see figure), but also promote the restoration of connections between nerve and muscle. The results were published in September in PNAS.

Ye previously identified compounds that activate the same signals as the neuron growth factor BDNF (brain-derived neurotrophic factor). These compounds – 7,8-dihydroxyflavone and deoxygedunin — have shown promise in experimental models of diseases such as stroke and Parkinson’s disease. They also have been used to tweak learning and memory in animal models.
