1 Docosahexanoic acid antagonizes TNF-alpha-induced necroptosis by attenuating oxidative stress, ceramide production, lysosomal dysfunction, and autophagic features. Docosahexaenoic Acids tumor necrosis factor Mus musculus
2 OBJECTIVE: It was previously reported that docosahexanoic acid (DHA) reduces TNF-alpha-induced necrosis in L929 cells. Docosahexaenoic Acids tumor necrosis factor Mus musculus
3 OBJECTIVE: It was previously reported that docosahexanoic acid (DHA) reduces TNF-alpha-induced necrosis in L929 cells. Docosahexaenoic Acids tumor necrosis factor Mus musculus
4 The present study was designed to investigate cellular and biochemical mechanisms underlying the attenuation of TNF-alpha-induced necroptosis by DHA in L929 cells. Docosahexaenoic Acids tumor necrosis factor Mus musculus
5 METHODS: L929 cells were pre-treated with DHA prior to exposure to TNF-alpha, zVAD, or Necrostatin-1 (Nec-1). Docosahexaenoic Acids tumor necrosis factor Mus musculus
6 DHA attenuated multiple biochemical events associated with TNF-alpha-induced necroptosis, including ROS generation, ceramide production, lysosomal dysfunction, cathepsin L activation, and autophagic features. Docosahexaenoic Acids tumor necrosis factor Mus musculus
7 CONCLUSIONS: DHA effectively attenuates TNF-alpha-induced necroptosis and autophagy, most likely via its ability to inhibit TNF-alpha-induced sphingolipid metabolism and oxidative stress. Docosahexaenoic Acids tumor necrosis factor Mus musculus
8 CONCLUSIONS: DHA effectively attenuates TNF-alpha-induced necroptosis and autophagy, most likely via its ability to inhibit TNF-alpha-induced sphingolipid metabolism and oxidative stress. Docosahexaenoic Acids tumor necrosis factor Mus musculus
