Abstract
Background: Endotoxin is a significant contributing factor underlying the occurrence of fever, diarrhea, inflammation, edema, coagulation, shock, and other syndromes associated with Gram-negative bacterial infections. To date, there is no effective treatment for endotoxemia.
Aim: The aim of this study was to characterize differentially expressed genes in sinomenine-treated and LPS-induced endothelial cells by microarray analysis, and to determine the potential pharmacological activity of sinomenine.
Design: The cultured cells of five treatment groups (n = 3, respectively) were collected. Participants: Total RNA was extracted and subjected to Agilent Porcine 4 × 44 K whole genome microarray.
Methods: Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology software were applied to screen and analyze differentially regulated genes.
Results: The results showed that 723 differentially regulated genes were identified including 410 up-regulated genes and 313 down-regulated genes in therapy group vs. LPS group. Ten genes may be key controlled genes in the pathogenesis of LPS, including 5 up-regulated genes (ARG1, TLR2, IL1A, VCAM1, DKK3) and 5 down-regulated genes (HABP2, ID1, CHDH, GPX3, PTGFR), which primarily contribute to biological processes such as inflammatory response, vascular lesion, metabolic process, cell cycle. IL1A and FMO3, were considered as potent target genes.
Conclusion: Global gene expression profile analysis showed that sinomenine might effectively be useful to regulate inflammatory responses as part of future anti-endotoxin therapies.
