Figure Lengend Snippet: APE1/Ref-1 Redox Function Affects Immunosuppressive TME ( A ) Correlation between APE1/Ref-1 expression and the infiltration of MDSCs and CD8 + T cell analyzed within the TCGA database. ( B ) Representative IHC image of high (upper panel) or low (lower panel) APE1/Ref-1 expression. C - F . mIHC staining reveals the infiltration of immune cells in paraffin-embedded tumor tissues from CRC patients, categorized by high APE1/Ref-1 expression (left panel) and low APE1/Ref-1 expression (right panel), along with corresponding statistical analyses ( D - F ). Human PMN-MDSC are defined as CD11B + CD14 − 29,30 . The white horizontal line in the images denotes 200 μm. G . Visualization of luminex liquid suspension chip detection, where the interior of the circle indicates the inhibitory effect of the drug on cytokine expression, while the exterior indicates a promoting effect. The length of the fan segments represents the magnitude of fold change (FC), quantified as log2(FC) following drug treatment; the color of the segments corresponds to the P value, with gray indicating a lack of statistical significance. H - I . Assessment of alterations in the expression levels of tumor necrosis factor-α (TNF-α, H ) and CXCL1 ( I ) subsequent to APX3330 treatment in HT-29
