Two-Drug Combo Makes a Difference in FA
Results from a clinical trial conducted in Spain involving 20 individuals with Friedreich's ataxia (FA) show that a combination therapy using two drugs, idebenone and deferiprone (DFP), demonstrated a "stabilizing effect" in neurological function and reduced abnormal heart-muscle enlargement in participants who received the two-drug combo for a period of 11 months.
Read MoreLow-Dose Ataluren Shows Some Benefit in DMD/BMD
A low-dose regimen of ataluren (formerly called PTC124), an experimental drug developed by PTC Therapeutics to treat Duchenne muscular dystrophy (DMD) or Becker muscular dystrophy (BMD) caused by a certain type of genetic mutation, is superior to a high-dose regimen or a placebo.PTC announced the findings at the 15th International Congress of the World Muscle Society, held in Kumamoto, Japan, Oct. 12-16, 2010, and in an Oct. 15 press release. (See Pivotal Data Presented at the World Muscle Society Congress Suggest Ataluren Slows the Loss of Walking Ability in Patients with Nonsense Mutation Duchenne/Becker Muscular Dystrophy.)
Read MoreCardiomyopathy in Becker MD
In many forms of muscular dystrophy, including Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD), weakness and degeneration of the cardiac muscle can be a major part of the disease, and one that frequently shortens life.Now, doctors at Ohio State University and Nationwide Children's Hospital in Columbus, Ohio, as well as Washington University in St. Louis and the University of Utah in Salt Lake City, have identified specific mutations in the dystrophin gene that predict whether heart muscle weakness (cardiomyopathy) will occur earlier or later in the course of BMD.

Immune Response Must Be Considered in DMD Gene Therapy
Editor's note: This story was updated April 27, 2012. Immune-system rejection of newly synthesized dystrophin protein occurred in at least some of the boys with Duchenne muscular dystrophy (DMD) who participated in a safety trial of dystrophin gene therapy.The finding was a partial surprise to researchers and demonstrates the value of small, phase 1 clinical trials.

A Dozen Ways to Ask for Help
I was taught it is better to give than to receive. Don’t ask for handouts. Pull your own weight.All my life, I told myself, “You are only handicapped if you allowed yourself to be handicapped.” That belief worked for me when I could still stand and walk. Now that my legs don’t function and my hands are extremely weak, I recognize that my physical being has limitations. I have readjusted my self-perception and understand that I need people to help me.

One Giggle at a Time
While cleaning a messy drawer, I began to smile and then chuckle at the foolish objects I have kept. When will I ever need a used twisty tie or a bent nail? And then there are the keys that don’t seem to fit anything. Am I just deceiving myself in believing these should be saved? Don’t laugh at me, laugh with me.

James Lupski’s story has all the elements of a good sci-fi tale: a research scientist determined to uncover the cause of his own genetic disease, a friend and colleague who’s also an intrepid gene hunter, and a futuristic technology that not only pinpoints the molecular cause of the research scientist’s disease, but also opens the door to a new era of personalized medicine.

Decoy Receptor Lures Myostatin, Helps Muscles
Luring away myostatin, and possibly other proteins that inhibit muscle growth, using a gene for a "decoy receptor" increased muscle size and strength in mice with a muscle disease resembling human Duchenne muscular dystrophy (DMD), a new study has found.The investigation builds on earlier findings showing that various strategies for interfering with myostatin, a naturally occurring protein that inhibits muscle growth, can build muscle in mice, and that cows and humans naturally deficient in myostatin develop large muscles.
