A major toxic mechanism of PS ASOs mediated by PS ASO protein interactions. Toxic PS ASOs bind more proteins more tightly. The tight interactions between PS ASOs and proteins can cause paraspeckle protein mislocalization to the nucleolus, in an RNase H1-dependent manner, and can affect pre-rRNA synthesis, leading to nucleolar stress and apoptotic cell death.
