CCL21 and adrenal cortex carcinoma: Supplementary Figure S1A shows the distribution of SLC genes positively (log2FC ≤ −1) or negatively (log2FC ≥ 1) associated with OS in all tumor types. The analysis revealed that the highest percentage of SCL genes negatively associated with OS was observed for UVM (16%), THYM (14%), ACC (13%), KIRP (12%), and MESO (11%). Conversely, the pro-survival SLC genes were mainly represented in ACC (17%), KIRC (13%), THYM (13%), and PCPG (11%) (Supplementary Figure S1A).
