(University of Alabama at Birmingham) An experimental drug reported in Nature Communications suggests that a " path is clearly achievable " to treat currently untreatable cases of cystic fibrosis disease caused by nonsense mutations. This includes about 11 percent of cystic fibrosis patients, as well as patients with other genetic diseases, including Duchenne muscular dystrophy,β-thalassemia and numerous types of cancers, that are also caused by nonsense mutations.

During protein synthesis, nonsense mutations, resulting in premature stop codons (PSCs), produce truncated, inactive protein products. Such defective gene products give rise to many diseases, including cystic fibrosis, Duchenne muscular dystrophy (DMD), and some cancers. Small molecule nonsense suppressors, known as TRIDs (translational read-through–inducing drugs), stimulate stop codon read-through. The...

(UT Southwestern Medical Center) DALLAS - Nov. 4, 2020 - A mutation in the gene that causes cystic fibrosis may accelerate heart function decline in those with Duchenne muscular dystrophy (DMD), a new study by UT Southwestern researchers suggests. The findings, published online recently in theJournal of the American Heart Association, could help doctors develop new strategies to preserve heart function in this population, potentially extending patients' lives.

Conclusion To conclude, this study suggests a preserved plasticity in the skeletal muscle of a patient with MELAS. More importantly, Resistance Training appears to be a safe and effective method to increase skeletal muscle function in this patient population, and this effect is mediated by both neuromuscular and mitochondrial adaptations. However, particular attention and caution is needed in the interpretation of the data of this single case study and further studies are warranted including larger sample of patients. Ethics Statement For this case study the participant caregiver provided written informed consent. Auth...

A Chinese scientist shocked the scientific community a couple of days ago with the announcement of having modified the very blueprint of life. If his claims are true, he tried to bestow two baby girls the ability to resist possible future infections with HIV. The outrage shows that humanity is not prepared to utilize the power of gene editing on embryos yet. We have no idea about the biological consequences, and we haven’t tackled the necessary legal and ethical issues. Genes to become toys of the “Gods”? Humanity has come a long way since Aldous Huxley pinned down how methods of genetic engineering, bio...

(American College of Medical Genetics and Genomics) The last decade has seen tremendous progress in the development of new drugs for patients with genetic disorders, including Cystic Fibrosis, many lysosomal storage disorders (Gaucher disease, Fabry disease and others) and most recently, Duchenne Muscular Dystrophy and Spinal Muscular Atrophy (SMA). The American College of Medical Genetics and Genomics (ACMG) is concerned with the staggering projected cost of these new treatments.
