89Zr Immuno-PET Imaging of Tumor PD-1 Reveals That PMA Upregulates Lymphoma PD-1 through NFκB and JNK Signaling

Figure 8

Effects of PMA on signaling pathways in EL4 tumors. Immunoblots of tumor tissue for PD-1, HIF-1α, p-IκBα, and p-JNK with quantified protein band intensities corrected by controls. Animals were intraperitoneally administered with vehicle or PMA for 3 days. Bars represent the of quintuple mice per group. , , and .
