KISS1 and prostate adenocarcinoma: Then, as for the ImmuneScore [21], the expression of KISS1 was significantly negatively correlated with immune infiltration in COAD (N = 282, R = −0.20, p = 6.1e − 4), COADREAD (N = 373, R = −0.21, p = 4.2e − 5), and STAD (N = 388, R = −0.30, p = 1.4e − 9) and positively correlated with immune infiltration in PRAD (N = 495, R = 0.20, p = 5.1e − 6) (Figure 4b).
