Fig. 8. SLC25A22 depletion synergized with anti-PD1 therapy in KRAS-mutant CRC.

Fig. 8

a SLC25A22 knockout synergized with anti-PD1 in suppressing the growth of CT26 allografts (n = 10) and b MC38-KrasG12V allografts (n = 8). Each dot represents an independent tumor. c CD8+ T-cell and IFN-γ expression was induced by combined SLC25A22 knockout and anti-PD1, whilst MDSC infiltration was reduced by the combination of SLC25A22 knockout plus anti-PD1 therapy in CT26 allografts (n = 5) and d MC38-KrasG12V allografts (n = 8). Each dot represents an independent tumor. e siSlc25a22-encapsulated nanoparticles (VNP-siSLC25A22) synergized with anti-PD1 to suppress MC38-KrasG12V allografts growth and increased CD8+ T-cell activation (n = 10) and f their effect on IFN-γ levels on CD8+ T cells (siNC+IgG and siSLC+IgG: n = 10 per group; siNC+Anti-PD1 and siSLC+ Anti-PD1: n = 9 per group). Each dot represents an independent tumor. g The overall graphical summary of the study (Created with BioRender.com). Data are presented as mean ± SEM for growth curve (a, b, e) and ± SD for others (af). Two-tailed two-way ANOVA for growth curve comparison (a, b, e). Two-tailed Student’s t test for two-group comparison (a, c). Two-tailed Mann–Whitney U test for two-group comparison (b, df). ns, no significance. Source data are provided as a Source Data file.
