STAT1 and metastatic melanoma: As shown in Supplementary Figure S14A, STAT1 expression was revealed to be positively correlated with CTL infiltration levels in endometrial carcinoma (r = 0.363, p = 2.48e−18), acute myeloid leukemia (r = 0.335, p = 2.53e−3), neuroblastoma (r = 0.363, p = 1.52e−13), metastatic melanoma (r = 0.623, p = 1.69e−35), and triple negative breast cancer (r = 0.655, p = 6.97e−30).
