illustrated that neuronal precursor cell-expressed developmentally downregulated 4 (Nedd4), is capable of ubiquitylating as well as degrading VDAC2/3, thereby modulating ferroptotic processes in melanoma cells triggered by erastin specifically (Yang et al., 2020)

The presence of Nrf2 and its inhibitor Keap1 in plasma is associated with damaged vascular endothelial cell-, macrophage-and other cell-associated leakage secondary to the loss of cell membrane integrity due to lipid peroxidation following chronic inflammation and oxidative stress (Kasprzak et al., 2020), and Nrf2 and Keap1 in circulation are markers of severe inflammation and oxidative stress (Tu et al., 2019)

The extract was rotary evaporated at 30 C to a volume of 2 ml, acidified to pH 4 with formic acid, and 200 l aliquots were purified using preparative HPLC (Agilent Technologies, 1260 Infinity) over a Luna 5 m phenyl-hexyl 100 (250 10 mm) column and a 15 min linear gradient from 0% acetonitrile in H 2 O to 16% acetonitrile in H 2 O at 4 ml min 1 flow
