No Regs Now

1 FDA to Strictly Regulate Gluten-Free Products

The Food and Drug Administration will institute strict new regulations on gluten-free products, reports CBS News correspondent Elaine Quijano. The market is growing for gluten-free foods which account for $2.6 billion in sales, up 30 percent in the last five years. However, the gluten-free label is not currently regulated. The strict guidelines, which are expected to take effect early next year, will be good news for people with allergies to gluten, including roughly 3 million Americans with celiac disease, which includes symptoms such as constipation, bloating, numbness in the extremities and problems with digestion. Currently, a gluten-free diet is the only medicine available for celiac patients and is, essentially, a cure, notes Jennifer Shannon, a celiac patient.

It's the Jellyfish Cat

2 Glowing Cats May Help Fight AIDS

Creating cats with an immunity to the feline AIDS virus may also benefit humans by illuminating ways to fight HIV/AIDS, say Mayo Clinic researchers, who used jellyfish genes that made cats glow green. The new study findings are published in Nature Methods. Mayo Clinic researchers created a genome-based immunization strategy for fighting feline AIDS (feline immunodeficiency virus or FIV). The technique, called gamete-targeted lentiviral transgenesis, involves inserting genes into feline eggs before they're fertilized by sperm. The research team used a gene for a rhesus macaque which blocks cell infection by FIV, but they also used a jellyfish gene for tracking. It's the jellyfish gene that makes these special cats glow green. "It can help cats as much as people," says Eric Poeschla, M.D.

New Growth Signal Evades Drug

3 Protein in Cancer Cells Evade Cetuximab

Research conducted at the Dana-Farber Cancer Institute has found that a protein which becomes active in some cancer cells and makes them resistant to cetuximab, an antibody that binds to the epidermal growth factor receptor (EGFR) to stop cancer cells from growing. Patients respond quite well to the drug but it typically loses its effectiveness after one year of treatment. Researchers found that high amounts of heregulin cause the Her2/Neu gene to produce ERBB2 or it is activated by the protein ERBB3 which tells the cancer cells to grow independent of EGFR activation. Prior research has demonstrated ERBB2 activity in cetuximab-resistant cancer cells. Future research will confirm these results and look at using ERBB2 inhibitors in conjunction with cetuximab.
