Transcript

This approach may be used in cell system models of endoplasmic reticulum stress by manipulating the molecular expression of downstream pair components. The main advantage of this technique is to remove the impact of paired signaling by the visuali

Summary

In the present study, the expression is knocked down of two downstream signaling components of the PERK pathway, the cytoprotective calcineurin and the pro-apoptotic CHOP, by using specific shRNAs. In opposite ways, these modulate the susceptibility of primary cortical neurons to neurite atrophy after induction of endoplasmic reticulum stress.
