DGLA induces neurodegeneration in dopaminergic
neurons via ferroptosis.
(A) Percentage (%) of worms with healthy ADE neurons of worms exposed
to 100 μM DGLA ± 250 μM liproxstatin-1. (B) Percentage
(%) of worms with healthy ADE neurons in wild-type C. elegans treated with 100 μM DGLA ± 500 μM Trolox (vitamin
E). (C) Percentage (%) of worms with healthy ADE neurons for Pdat-1::gfp worms treated with 100 μM DGLA ±
100 μM 2,2′-bipyridine. (D) Percentage (%) of worms with
healthy ADE neurons in Pdat-1::gfp and Pdat-1::gfp;bli-3 worms treated with 100 μM DGLA. (E) Percentage (%) of worms
with healthy ADE neurons for Pdat-1::gfp and Pdat-1::gfp;ftn-1 worms treated with 100 μM DGLA.
(F) Percentage (%) of worms with healthy ADE neurons with Pdat-1::gfp and Pdat-1::gfp;ced-3 worms
treated with 100 μM DGLA ± 250 μM liproxstatin-1.
