SLC38A2 and pancreatic adenocarcinoma: In PAAD, SLC38A2 shows a strong positive correlation with infiltrating T helper cells (R = 0.588, p < 0.001) and a moderate positive correlation with infiltrating Tcm (R = 0.405, p < 0.001), Neutrophils (R = 0.402, p < 0.001), Th2 cells (R = 0.380, p < 0.001), Th1 cells (R = 0.374, p < 0.001), and Macrophages (R = 0.314, p < 0.001) (Figure 3D).
