SORT1 and neoplasm: We performed RT-qPCR on tumor samples from 12 LUAD patients, and the results suggested significant differences in the expression of TRAV38-2DV8 and SORT1 in the low- and high-risk groups and were consistent with the trend in the TCGA cohort, while NRAS expression was not significantly different in the two risk subgroups (Figure 4H).
