Figure Lengend Snippet: (A) Time-dependent changes in cytokine and chemokine production in LPS-stimulated THP-1 cells. After LPS (10 μg/ml) treatment for 15, 30, 60, or 120 min without any agents and with minocycline (50 μg/ml), tigecycline (50 μg/ml), or doxycycline (50 μg/ml), cytokines and chemokines were measured using Multi Plex according to the manufacturer’s protocols. * p <0.05 compared with LPS only at 60 min. ** p <0.05 compared with LPS only at 120 min. Mino: minocycline, Tige: tigecycline, Doxy: doxycycline. (B) The rate of cytokine and chemokine production in the THP-1 cell line compared to the production of cytokines and chemokines by LPS stimulation without tetracyclines. After LPS treatment (10 μg/ml) for 30, 60, 120 or 240 min without any agents and with minocycline (50 μg/ml), tigecycline (50 μg/ml), or doxycycline (50 mg/ml), cytokines and chemokines were measured with Multi Plex.

Figure Lengend Snippet: Effects of minocycline, doxycycline, and tigecycline on the modulation of NF-κB, phospho-NF-κB, IKKα/β, phospho-IKKα/β, IκBα, and phospho-IκBα in LPS-stimulated THP-1 cells. THP-1 cells were incubated without or with 10 μg/ml LPS, or with LPS plus minocycline (50 μg/ml), doxycycline (50 μg/ml), or tigecycline (50 μg/ml) for 30, 60, or 120 min. NF-κB, phospho-NF-κB, IKKα/β, phospho-IKKα/β, IκBα, and phospho-IκBα were assessed with Western blotting.

Figure Lengend Snippet: Effects of tetracyclines (minocycline, doxycycline, and tigecycline) on the activation of phospho-ERK1/2 and phospho-p38 in LPS-stimulated THP-1 cells. THP-1 cells were incubated without or with 10 μg/ml LPS, or with LPS plus minocycline (50 μg/ml), doxycycline (50 μg/ml), or tigecycline (50 μg/ml) for 30 or 60 min. Phospho-p38 and phospho-ERK1/2 were assessed with Western blotting.

Figure Lengend Snippet: SB203580, U0126 and BAY11-7082 suppressed TNF-α and IL-8 production in LPS-stimulated THP-1 cells on treatment with or without tetracyclines. THP-1 cells were pre-incubated by SB203580 (10 μM), U0126 (5 μM) and BAY11-7082 (5 μM) for 30 min, followed treatment without or with LPS (10 μg/ml), or with LPS (10 μg/ml) plus minocycline (50 μg/ml), doxycycline (50 μg/ml), or tigecycline (50 μg/ml) for 60 min. TNF-α were measured with ELISA. * p <0.05, ** p <0.01, *** p <0.001 compared to the measurement without the inhibitor in the same group. Abbreviation; SB: SB203580, U: U0126, BAY: BAY11-7082.
