Title

Protective effect of bacterial lipase on lipopolysaccharide-induced toxicity in rat cardiomyocytes; H9C2 cell line

Pages

  35-42

Abstract

 Introduction: Cardiovascular system is highly sensitive to LPS-induced oxidative damage. This study aimed to show the inhibitory effect of bacterial Lipase on LPS-induced cardiomyoblasts toxicity. Methods: Rat cardiomyoblasts H9C2 were classified into Control, LPS (cells received 0. 1, 1 and 10 μ g/ mL LPS) and LPS+ Lipase groups. In LPS+Lipase group, different concentrations of Lipopolysaccharide were pre-incubated with 5 mg/mL bacterial Lipase at 37˚ C overnight prior to cell treatment. After 72 hours, cell viability was assessed by MTT assay. The expression of key genes related to Toll-Like Receptor Signaling pathways was assessed by real-time PCR assay. Percentage of fatty acids was evaluated in each group using gas chromatography assay. The levels of NO was also measured using the Griess reaction. Results: Data showed H9C2 cells viability was decreased after exposure to LPS in a dose-dependent manner (P < 0. 05). Incubation of LPS with Lipase increased cell survival rate and closed to near-tocontrol levels (P < 0. 05). Lipase had the potential to blunt the increased expression of IRAK and NF-κ B in cells after exposure to the LPS. Compared to the LPS group, Lipase attenuated the increased level of NO-induced by LPS (P < 0. 05). Gas chromatography analysis showed the reduction of saturated fatty acids in cells from LPS group while the activity of Lipase prohibited impact of LPS on cell fatty acid composition. LPS decreased the ability of cardiomyoblasts to form colonies. Incubation of LPS with Lipase enhanced clonogenic capacity. Conclusion: Reduction in Lipopolysaccharide-induced cytotoxicity is possibly related to Lipase activity and reduction of modified Lipopolysaccharide with toll-like receptor.
