Figure 7. UBA2 is highly expressed in LUAD and is associated with poor prognosis in LUAD patients. (A) Random forest feature importance ranking for the SUMOPS genes; (B–E) The expression of UBA2 between LUAD and normal tissues in the (B) GSE10072, (C) GSE18842, (D) GSE33479 and (E) GSE33532 cohorts. (F–I) Prognostic analysis investigating the role of UBA2 in predicting outcomes in the (F) GSE11969, (G) GSE13213, (H) GSE68465 and (I) GSE72094 cohorts. *p < 0.05; **p < 0.01, ***p < 0.001.
