Other BCL2 family genes such as PMAIP1 (NOXA) and BAX were also higher in TI-Tregs than other PB-Tregs cells from human ccRCC (Supplementary Fig. 1c); MCL1 was slightly higher in TI-Tregs than PB-Tregs in HCC (Supplementary Fig. 1d). This evidence concerns the gene MCL1 and hepatocellular carcinoma.
