How many is too many? Exploring the toxic CAG threshold in the Huntington’s disease brain

How many is too many? Exploring the toxic CAG threshold in the Huntington’s disease brain

New work from researchers in London uses mice to narrow in on the number of CAG repeats needed to cause symptoms of Huntington’s disease. Their work points to fewer than 185 CAGs as a threshold.

The director’s cut: how CAG repeats change the editing of genetic messages

The director’s cut: how CAG repeats change the editing of genetic messages

Scientists in Massachusetts have recently advanced our understanding of how repetitive sequences in DNA can disrupt the creation and editing of genetic messenger molecules in cells, and how this could lead to the production of harmful proteins.

CRISPR-based drugs: one giant leap for mankind

CRISPR-based drugs: one giant leap for mankind

Casgevy is the first CRISPR-based drug to make its way through the approval process, all but curing Sickle Cell Disease and it’s paving the way for similar drugs targeting other diseases. Is Huntington’s disease next?

Putting it in print: GENERATION HD1 study results published

Data from GENERATION HD1, the Phase 3 clinical trial testing the huntingtin-lowering drug tominersen, have just been published in a scientific journal. The trial ended a while back, so why is this an important milestone, and what’s next?

Regulating repetition: Gaining control of CAG repeats could slow progression of Huntington’s disease

Regulating repetition: Gaining control of CAG repeats could slow progression of Huntington’s disease

Many diseases are caused by repetitive DNA sequences. Understanding the regulation of those repetitive sequences may hold the key for unlocking therapeutics for Huntington’s disease. A team from Toronto has just advanced our understanding.
