Single-patient pilot study shows the ability of antisense oligonucleotide to suppress mutant ALS gene

Using a short, synthetic chain of chemically modified nucleotides engineered in the RNA Therapeutics Institute at UMass Chan Medical School, Robert H. Brown Jr., DPhil, MD, Jonathan Watts, PhD, and colleagues have shown the ability to suppress mutant forms of an ALS gene known as C9ORF72 in a single-patient pilot study.

New computer program can read any genome sequence and decipher its genetic code

Yekaterina "Kate" Shulgina was a first year student in the Graduate School of Arts and Sciences, looking for a short computational biology project so she could check the requirement off her program in systems biology. She wondered how genetic code, once thought to be universal, could evolve and change.

Improper Z-RNA recognition contributes to pathogenesis of Aicardi-Goutières syndrome

Like DNA, RNA molecules contain information through unique combinations of four different nucleotides. However, through a molecular process called RNA editing, chemical changes can be made to adenosine nucleotides that convert them to a nucleotide called inosine by enzymes known as adenosine deaminases (ADARs).
