RAB9A and cancer: In the Kaplan-Meier plotter analysis, high RAB9A expression was associated with poor survival among patients with ER-positive cancers who received endocrine treatment (HR = 2.05 (1.48–2.83), P = 8.6 × 10−6) whereas an opposite effect was seen among ER-negative cases (HR = 0.70 (0.53–0.94), P = 0.015) (Supplementary Figure 9).
