OBJECTIVE: To investigate the effects of ligustrazine injection on type I collagen, matrix metalloproteinase-1 (MMP-1) and tissue inhibitor of metalloproteinase-1 (TIMP-1) expressions in human peritoneal mesothelial cells (HPMCs) cultured in high glucose conditions.
METHODS: HPMCs were isolated from human omenta by trypsin digestion method and subcultured. Then, the HPMCs were divided into normal control group, high glucose group and high glucose plus low-, medium- and high-dose ligustrazine (10, 20 and 40 mg/L ligustrazine respectively) groups. Semi-quantitative reverse transcription-polymerase chain reaction was used to detect the expressions of type I collagen, MMP-1 and TIMP-1 mRNAs in HPMCs. Proteins of type I collagen, MMP-1 and TIMP-1 in culture supernatants were measured by enzyme-linked immunosorbent assay (ELISA). Cell protein concentration was measured by trace bicinchoninic acid method to correct the ELISA assay results.
RESULTS: Ligustrazine injection could significantly decrease high glucose-induced type I collagen and TIMP-1 expressions in a dose-dependent manner both in protein and gene levels (P<0.05, P<0.01). In addition, medium- and high-dose ligustrazine injection could significantly increase MMP-1 expression which was inhibited by high glucose concentrations (P<0.05).
CONCLUSION: Ligustrazine injection does not only decrease type I collagen synthesis, but also promote its degradation by modulating unbalanced MMP-1/TIMP-1 expression in HPMCs cultured in high glucose conditions.
