New Insights Into Why Huntington’s Disease Has Delayed Onset

New Insights Into Why Huntington’s Disease Has Delayed Onset

A highly-anticipated scientific paper has landed! This new work challenges current theories in Huntington’s disease research, uncovering how runaway CAG repeats erode cell identity in certain types of brain cells, leading to their death.

Spotting HD Early: The Clues Hidden in Young Brains

Spotting HD Early: The Clues Hidden in Young Brains

Researchers have detected early changes in brain scans and biomarkers in young people with the Huntington’s disease gene, 20 years before symptoms are predicted to appear. These findings could help develop medicines to treat HD earlier in life.

Two birds, one stone: HTT-lowering drugs also target CAG expansions

Two birds, one stone: HTT-lowering drugs also target CAG expansions

In a surprising twist, oral HTT-lowering drugs also slow somatic expansion in the HTT gene. A new study that used cells in a dish for this fortuitous discovery identified the gene PMS1 as a key player in the slowing of CAG expansions.

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.

Could halting CAG expansions be a new treatment for HD?

Could halting CAG expansions be a new treatment for HD?

The gene MSH3 is getting a lot of attention in HD research lately. New findings suggest MSH3 lowering could halt CAG repeat expansions, offering a new therapeutic avenue.
