Trimethylamine N-oxide promotes atherosclerosis via CD36-dependent MAPK/JNK pathway
Abstract
Background Many studies have identified trimethylamine N-oxide (TMAO) as a new risk factor of cardiovascular diseases. It has been suggested that TMAO promotes atherosclerosis development. However, the underlying mechanism is still unclear.Methods Apoe-/- mice were fed a high-fat diet and given water with or without TMAO for 8-week. Histological and immunohistological analyses were used to evaluate the atherogenic effect of TMAO in vivo. We also employed peritoneal elicited macrophages and RAW264.7 to assess the role of MAPK/JNK pathway in TMAO-induced formation of foam cells.Results TMAO significantly promoted plaque progression in apoe-/- mice fed with high-fat diet for 8 weeks. Besides, macrophage recruitment, CD36 and proinflammatory cytokine expressions were enhanced by TMAO in plaque lesions. In vitro, TMAO increased the macrophage migration and the expression of TNF-α, IL-6 and ICAM1. In addition, CD36 expression and foam cell formation induced by ox-LDL were also enhanced by TMAO, which could be attenuated by siRNA-mediated knockdown of CD36. We additionally used MAPK inhibitor (SB230580) and JNK inhibitor (SP600125) to assess the MAPK/JNK pathway in TMAO-induced CD36 expression. Western blotting showed that both SB230580 and SP600125 could reduce the expression of CD36 induced by ox-LDL and TMAO. Moreover, SB230580 and SP600125 could also reduce the formation of foam cells.Conclusions TMAO promotes the atherosclerosis in vivo and in vitro.CD36/MAPK/JNK pathway may play a crucial role in TMAO-induced formation of foam cells.

In the citing paper
“MAPK/JNK pathway seems to play a critical role in TMAO-induced atherosclerosis since, when SB230580 (a MAPK inhibitor) and SP600125 (a JNK inhibitor) were used, foam cell formation and CD36 expression were reduced. Foam cell formation was also attenuated by the use of siRNA-mediated knockdown of CD36 [13].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
