[Retracted] Minocycline Induces Autophagy and Inhibits Cell Proliferation in LPS-Stimulated THP-1 Cells

Figure 2

LPS-induced autophagy was mediated by TNF-α in THP-1 cells. (a) LPS-induced autophagy in a dose-dependent manner. THP-1 cells were treated with indicated concentration of LPS for 12 h. (b) THP-1 cells were treated with 1 μg/ml LPS for 6, 12, or 24 h. (c) Effect of specific anti-TNF-α monoclonal antibody infliximab on LPS-induced autophagy. THP-1 cells were preincubated with 5 μm infliximab for 1 h followed with 1 μg/ml LPS for 12 h. (d, e, and f) Densitometric analysis of the blots showing the ratios of LC3-II to LC3-I. Data were represented as the (, , vs. control; ^▲ vs. LPS). IN: infliximab.
