Rewiring ALS by modulating the autophagy receptor SQSTM1.

Drug screening for genetic disorders is limited by difficulty identifying disease-relevant phenotypes. In this issue, Roussange et al., show that reverse phenotypic mapping could uncover therapeutic gene expression signatures. Using this approach, they identified prazosin, which increases SQSTM1 expression and rescues disease phenotypes in iPSC-derived motor neurons and zebrafish model of amyotrophic lateral sclerosis with SQSTM1 haploinsufficiency.
