Background and Objective: The antibiotic minocycline (MINO) is known to have anti-inflammatory activity. This study aimed to examine the effects of MINO on hydrogen peroxide (H2O2)-induced cell death and interleukin (IL)-8 production, which have been shown to increase during inflammation, using small airway epithelial cells (SAECs). Materials and Methods: The SAECs were pretreated with MINO (1, 5 and 10 μM) for 24, 48 or 72 h and subsequently exposed to H2O2 (100 μM) for 6 h. Cell viability was assessed using the WST-8 assay and levels of IL-8 protein were measured using an enzyme-linked immunosorbent assay (ELISA). Tukey’s multiple comparison test was used for analysis of statistical significance. Results: Treatment of SAECs with 10 μM MINO or greater than 100 μM H2O2 significantly decreased cell viability. However, pretreatment with 1 μM MINO for 24 h significantly suppressed the H2O2-induced decrease in cell viability. In addition, IL-8 production increased in the H2O2 treated group as compared to the control group (not treated with H2O2), whereas IL-8 production decreased significantly following pretreatment with MINO (1, 5 or 10 μM) for 48 or 72 h. Conclusion: It was suggested that pretreatment of SAECs with low concentrations of MINO for 24 or 48 h has a cytoprotective effect and pretreatment for 48 or 72 h suppresses IL-8 production indicating a potential anti-inflammatory effect.
