Figure 4. Increased level of 4‑HNE-protein adducts in C. elegans treated with 4‑HNE. Synchronized L4 worms were
kept in liquid culture for 3 days in medium containing 1 mM 4‑HNE.
The medium was replaced every 12 hr with fresh medium containing 4‑HNE.
The level of 4‑HNE-protein adducts was determined in 5-day-old worms
by competitive ELISA [
