Neurogeneticists have discovered a novel genetic mutation and associated buildup of toxic proteins in the brain -- a type of buildup distinct from amyloid or tau, proteins that have long been the ...

They used worms with a mutation in a cuticle collagen gene, which makes it easier for EDC compounds to permeate the worm, in order to analyze lower exposure doses. For their experiments, the ...

Mutations could cause different genes to be switched on or off ... If it is a structural protein such as collagen, it might lose its strength. However, most DNA mutations do not alter a protein ...
