Abstract

Objectives

The purpose of this study was to investigate the effect of Phellinus linteus cheonghyeol plus (PLCP) on antioxidant and inhibition of inflammatory factor expression associated with dyslipidemia in HUVEC.

Methods

The scavenging activity of DPPH and ABTS radical of PLCP was measured in HUVEC. The expression levels of NF-κB, p-IκBα, ERK, JNK, and p38 proteins were measured after treating with TNF-α in HUVEC. The expression levels of MCP-1, ICAM-1, and VCAM-1 mRNA and biomarkers were measured after treatment with TNF-α in HUVEC

Results

  1. PLCP increases DPPH and ABTS radical scavenging activity in a concentration dependent manner.

  2. PLCP significantly decreased the concentration of NF-κB, p-IκBα, ERK, JNK protein compared to the control at concentrations of 100 μg/ml or more, and significantly decreased concentration of p38 protein at all concentrations.

  3. PLCP significantly decreased MCP-1 mRNA expression levels at 100 μg/ml or more compared to the control. ICAM-1 and VCAM-1 mRNA expression levels were significantly reduced at all concentrations compared to the control. MCP-1, ICAM-1 protein expression levels were significantly reduced compared to the control at concentrations of 100 μg/ml or more, and VCAM-1 protein expression levels were reduced at all concentrations.

Conclusions

These results suggest that PLCP has an antioxidant effect, and it has been experimentally confirmed that it can prevent or inhibit inflammatory diseases caused by dyslipidemia due to its inhibitory effect on inflammation-related factors in HUVEC.

DPPH(A) and ABTS(B) radical scavenging activity of PLCP. PLCP was incubated at 1, 10, 100, and 1000/with DPPH solution for 30 mins and ABTS solution for 10 mins. DPPH radical scavenging activities were determined by measurement of absorbance at 517 and ABTS radical scavenging activities were determined by measurement of absorbance at 732. The results were expressed as mean ± S.D from three independent experiments.

The total cell extracts were subjected to 10% SDS-PAGE and western blot analysis with the respective primary and secondary antibodies. The results were presented by the mean ± S.D from three independent experiments (Significance of results, * ; p≤0.05, ** ; p≤0.01, *** ; p≤0.001 compared to control).

The mRNA expression levels were measured using a quantitative real-time PCR (qRT-PCR). The results were presented by the mean ± S.D from three independent experiments (Significance of results, * ; p≤0.05, ** ; p≤0.01, *** ; p≤0.001 compared to control).

MCP-1(A), ICAM-1(B) and VCAM-1(C) levels were measured using a ELISA kit. The results were presented by the mean ± S.D from three independent experiments (Significance of results, * ; p≤0.05, ** ; p≤0.01, *** ; p≤0.001 compared to control).
