R&D Systems human cytokine array kit
Effects of metformin on <t>cytokine</t> expression and ERK signaling <t>in</t> <t>RPMI</t> 2650 cancer cells in the presence of leptin. (A) Comparative cytokine array analysis of RPMI 2650 cancer cells treated with 10 ng/mL leptin alone and in combination with 10 mM metformin. 1=IL-2, 2=Serpin E1/PAI-1, 3=IL-18/IL-1FA. (B) Quantification of pERK/ERK expression levels in RPMI 2650 cancer cells treated with 10 ng/mL leptin and 10 ng/mL leptin+10 mM metformin. The expression of pERK and ERK was normalized to GAPDH expression. One-way ANOVA was performed (n=3). Data are presented as the group mean±standard deviation. ** P <0.01, *** P <0.005, and **** P <0.001. ERK, extracellular signal-regulated kinase; pERK, phosphorylated ERK; GAPDH, glyceraldehyde 3-phosphate dehydrogenase; IL, interleukin; PAI-1, plasminogen activator inhibitor-1.
