Could Glowing Cats Be The Key To Finding A Cure For HIV?

Photo courtesy of the Mayo Clinic Scientists have added a new species to the menagerie of animals that glow, after introducing jellyfish genes into cats that can now glow green.

Scientists report that they transferred genes from monkeys (and jellyfish) into cats in order to study feline immunodeficiency virus (FIV), the cat equivalent of HIV. In cats and in people, immunodeficiency viruses deplete infection-fighting T-cells. Key proteins called restriction factors that would normally defend against the viruses are ineffective. The research appears in the September issue of Nature Methods.

To research potential treatments, physicians, virologists, veterinarians and gene therapy researchers from the Mayo Clinic and in Japan sought to mimic the way evolution would generate protective protein versions, according to a Mayo Clinic press release. They inserted monkey versions of a gene into the cat genome using gamete-targeted lentiviral transgenesis. This is done by inserting genes into feline eggs before sperm fertilization.

The monkey restriction factor, TRIMCyp, blocks FIV by attacking and disabling the virus as it tries to invade a cell. In the lab, the transgenic cat lymphocytes resisted FIV replication. The scientists said that they can now test the potential of various restriction factors for Read more »

Is Sunburn More Likely On The Beach Or In The Mountains?

While vacationing in Idaho and Montana last week (blissfully off the grid), I experienced something beautiful: altitude. At 6,260 feet Stanley, Idaho is a mile higher than my home in San Diego. The skies there were a brilliant blue. There was daylight well after 10PM. The mornings were a chilly 35 degrees. And I got sunburned.

How can this be? Montana is over 1,000 miles north of San Diego. Shouldn’t the sun be stronger down here? Read more »

Environmental Cancer: A Report From The President’s Panel

While most of the news sources are reporting that cancers from the environment are ‘grossly underestimated’ in response to the recently released 240-page report from the President’s Cancer Panel, I want to focus on the steps individuals can take to lessen their personal exposure to environmental carcinogens. Collectively, these small actions can drastically reduce the number and levels of environmental contaminants. Read more »

The Spirit Of The Place: Samuel Shem’s New Book May Depress You

When I was in medical school I read Samuel Shem s House Of God as a right of passage. At the time I found it to be a cynical yet eerily accurate portrayal of the underbelly of academic medicine. I gained comfort from its gallows humor and it made me…

Eat To Save Your Life: Another Half-True Diet Book

I am hesitant to review diet books because they are so often a tangled mess of fact and fiction. Teasing out their truth from falsehood is about as exhausting as delousing a long-haired elementary school student. However after being approached by the authors’ PR agency with the promise of a…
