Fig. 4. Pharmaceutical IgG impairs oxaliplatin-induced ERK1/2 signal transduction.

Fig. 4

Colon cancer cells were treated with 6.25 µM oxaliplatin (OXA), 5 mg/mL PRIVIGEN® IgG (a, b), Tonglu® IgG (TL-IgG, c), IgG1 (d) or an OXA-containing combination for 36 h. We observed that OXA markedly activated ERK1/2, whereas PRIVIGEN® IgG, TL-IgG and IgG1 impaired ERK1/2 phosphorylation. The P-values were determined by Mann–Whitney U test. N = 5 for (a), (b) and (d); N = 4 for (c).
