[Effects of shuanglong pill on mRNA expression of platelet-derived growth factor A and monocyte chemoattractant
Objective:
To explore the molecular mechanism of Shuanglong Pill (SLP) in intervening atherosclerosis, mainly the effect of SLP on the mRNA expression of the platelet-derived growth factor-A (PDGF-A) and the monocyte chemoattractant protein-1 (MCP-1).
Methods:
Using the hyperlipoprotein serum (HLS) of cultured rabbits' aortic smooth muscle cell (SMC) to build the atherosclerotic cell model, and medicated serum acting on the cell model by serum pharmacologic method. The effect of SLP medicated serum on the level of PDGF-A, MCP-1 mRNA expression were observed and analysed by means of reverse transcriptase-polymerase chain reaction assay.
Results:
It was found that HLS stimulated mRNA expression of the PDGF-A and the MCP-1, but the medicated serum of SLP lowered their expression level.
Conclusion:
SLP could inhibit the function of cellular auto-secreting growth factor, it is one of the possible pharmacologic mechanism in intervening atherosclerosis.
Insights
Shuanglong Pill (SLP) reduces the expression of platelet-derived growth factor-A (PDGF-A) and monocyte chemoattractant protein-1 (MCP-1) mRNA. This suggests SLP may treat atherosclerosis by inhibiting cellular growth factor secretion.
Area of Science:
- Molecular biology
- Pharmacology
- Cardiovascular research
Context:
- Atherosclerosis is a complex cardiovascular disease.
- Platelet-derived growth factor-A (PDGF-A) and monocyte chemoattractant protein-1 (MCP-1) play key roles in its development.
- Understanding the molecular mechanisms of therapeutic interventions is crucial.
Purpose:
- To investigate the molecular mechanism of Shuanglong Pill (SLP) in treating atherosclerosis.
- To determine the effect of SLP on the mRNA expression of PDGF-A and MCP-1.
Summary:
- An in vitro atherosclerotic cell model was developed using hyperlipoprotein serum (HLS) on rabbit aortic smooth muscle cells (SMCs).
- SLP-medicated serum was applied to the model.
- Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to analyze PDGF-A and MCP-1 mRNA expression.
- Results showed HLS increased PDGF-A and MCP-1 mRNA levels, while SLP treatment significantly reduced them.
Impact:
- SLP demonstrates potential in intervening atherosclerosis.
- The findings suggest that SLP may exert its therapeutic effects by inhibiting the auto-secretion of cellular growth factors.
- This research provides insights into the pharmacological basis of SLP for atherosclerosis treatment.
