According to the CIBERSORT and CIBERSORT‐ABS algorithms, we found a statistically positive correlation between the immune infiltration of Tregs and KISS1 expression in tumors of ACC, BRCA, BRCA‐LumA, ESCA, HNSC, HNSC (HPV [human papillomavirus]‐), KIRC, KIRP, LUAD, LUSC, MESO, and THCA (Figure 5c), and the scatterplot data of ACC, BRCA‐LumA, HNSC, HNSC (HPV‐), KIRC, KIRP, ESCA, and LUAD are shown in Figure 5d. The gene discussed is KISS1; the disease is adrenal cortex carcinoma.
