From: Melatonin antagonizes lipopolysaccharide-induced pulpal fibroblast responses
Expression of MT1 and MT2 transcripts of cultured pulpal fibroblasts after co-incubation with E. coli LPS (20 μ g/mL) and exogenous melatonin at different concentration for 24 h. Relative densities of the representative PCR products from one of 3 independent experiments yielding similar results were shown (5A), in which one-way ANOVA did not reveal any statistical difference (5B, and 5C)
