Tender coconut water suppresses hepatic inflammation by activating AKT and JNK signaling pathways in an in vitro model of sepsis
Open accessAbstract
Tender coconut water (TCW) is a natural plant product rich in phytochemicals and protects against toxic liver injury. However, the mechanism by which TCW inhibits inflammation and tissue damage is unknown. We examined the effect of TCW on primary rat hepatocyte viability, cytokine-induced gene expression and proinflammatory signaling in an in vitro model of sepsis. We observed that TCW improved hepatocyte viability and protected hepatocytes against cytokine-mediated cell death. TCW suppressed IL-1β-mediated increases in Nos2, Tnf, and Il6 mRNA and increased heme oxygenase 1 (HMOX1) protein. TCW inhibited iNOS expression through activation of AKT and JNK pathways since inhibition of PI3K and JNK signaling reduced TCW’s effect on iNOS protein expression and activity. These results demonstrate that TCW reduces proinflammatory gene expression and hepatocyte injury produced by elevated inflammatory cytokines and nitric oxide production.

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.
