Importantly, AML patients with high RAB27B expression show reduced survival compared with those with low RAB27B expression in 2 different data sets — UALCAN (http://ualcan.path.uab.edu/) (Figure 2G) and TCGA (https://servers.binf.ku.dk/bloodspot/) (Figure 2H) — consistent with a recent report (29). Here, RAB27B is linked to acute myeloid leukemia.
