Abstract

Mangiferin has been shown to have the effect of improving dyslipidemia. Plasma free fatty acids (FFA) are closely associated with blood lipid metabolism as well as many diseases including metabolic syndrome. This study is to investigate whether mangiferin has effects on FFA metabolism in hyperlipidemic rats. Wistar rats were fed a high-fat diet and administered mangiferin simultaneously for 6 weeks. Mangiferin (50, 100, 150 mg/kg BW) decreased dose-dependently FFA and triglycerides (TG) levels in plasma, and their accumulations in liver, but increased the β-hydroxybutyrate levels in both plasma and liver of hyperlipidemic rats. HepG2 cells were treated with oleic acid (OA, 0.2 mmol/L) to simulate the condition of high level of plasma FFA in vitro, and were treated with different concentrations of mangiferin simultaneously for 24 h. We found that mangiferin significantly increased FFA uptake, significantly decreased intracellular FFA and TG accumulations in HepG2 cells. Mangiferin significantly increased AMP-activated protein kinase (AMPK) phosphorylation and its downstream proteins involved in fatty acid translocase (CD36) and carnitine palmitoyltransferase 1 (CPT1), but significantly decreased acyl-CoA: diacylgycerol acyltransferase 2 (DGAT2) expression and acetyl-CoA carboxylase (ACC) activity by increasing its phosphorylation level in both in vivo and in vitro studies. Furthermore, these effects were reversed by Compound C, an AMPK inhibitor in HepG2 cells. For upstream of AMPK, mangiferin increased AMP/ATP ratio, but had no effect on LKB1 phosphorylation. In conclusion, mangiferin decreased plasma FFA levels through promoting FFA uptake and oxidation, inhibiting FFA and TG accumulations by regulating the key enzymes expression in liver through AMPK pathway. Therefore, mangiferin is a possible beneficial natural compound for metabolic syndrome by improving FFA metabolism.

  • In Wistar rats and HepG2 cells, levels of intracellular FFA and TG accumulation were decreased in HepG2 cells.

    “Similarly, it was also observed in Wistar rats and HepG2 cells that levels of intracellular FFA and TG accumulation was decreased in HepG2 cells.”

    From Mangiferin: An effective therapeutic agent against several disorders (Review) (2018) · cites this paper as [86]

    The Results section reports that mangiferin decreased intracellular oleic acid (an FFA) and triglycerides in HepG2 cells. The Materials and Methods section confirms a rat experiment but does not identify the rats as Wistar, so that specific breed is not supported by our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Mangiferin upregulates mRNA levels of PPAR-alpha, CD36 and CPT-1.

    “It was observed that mangiferin upregulates the mRNA levels of peroxisome proliferator-activated receptor-α, fatty acid translocase (CD36) and carnitine palmitoyl transferase 1 (CPT-1) (86).”

    From Mangiferin: An effective therapeutic agent against several disorders (Review) (2018) · cites this paper as [86]

    The Results report increased CD36 and CPT-1 protein levels after mangiferin treatment in hyperlipidemic rats and HepG2 cells. The Methods specify that these proteins were measured by western blot; our copy does not report increased mRNA levels for them or for PPAR-α. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • In Wistar rats fed a high-fat diet and administered mangiferin (50, 100, 150 mg/kg) for 6 weeks, mangiferin improves FFA metabolism in a dose-dependent manner through promoting FFA uptake and oxidation.

    “Wistar rats were fed a high-fat diet and administered mangiferin (50, 100, 150 mg/kg) simultaneously for 6 weeks, which confirmed that mangiferin improves FFA metabolism in a dose-dependent manner through promoting FFA uptake and oxidation (86).”
  • Mangiferin promotes AMPK phosphorylation and upregulates expression of CD36 and CPT-1.

    “Furthermore, mangiferin promotes AMPK phosphorylation, and upregulates the expression of CD36 and CPT-1 (86).”
  • Mangiferin increases the AMP/ATP ratio upstream of AMPK, decreases DGAT2 expression, and decreases ACC activity.

    “Mangiferin increases the AMP/ATP ratio upstream of AMPK, decreases acyl-CoA:diacyl gycerol acyltransferase 2 (DGAT2) expression, decreases acetyl-CoA carboxylase (ACC) activity.”

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.
