Figure 8: Induction of cell proliferation by palmitic acid is dependent of IL-6. (a) Cells were untreated or treated with PA (75, 100, 125, and 150 μmol/L) for 24 hours. Cell viability was measured by a CCK-8 assay kit. Data are expressed as mean ± standard deviation ( ). * compared with control. (b) Cells were untreated or treated with PA (75 and 150 μmol/L) for 24 hours, with or without the presence of 10 μg/mL goat anti-human IL-6 polyclonal neutralizing antibody (IL-6 Ab) or control goat IgG in cell culture system. Cell viability was measured by a CCK-8 assay kit. Data are expressed as mean ± standard deviation ( ). * compared with treatments without IL-6 Ab.
