Though the UPR usually promotes healthy
endoplasmic reticulum function, sustained UPR activation sometimes results in diseases such as atherosclerosis, the deposition of fatty plaques on artery walls, among other conditions.
In this research, the scientists disturbed
endoplasmic reticulum function by introducing saturated fatty acids into cells to induce lipotoxic stress.
