RAB1A and colon adenocarcinoma: We found that lower Rab1A levels correlated with better survival and a favorable prognosis in liver hepatocellular carcinoma (P = 0.021) and pancreatic adenocarcinoma (P = 0.016), while high levels of Rab1A resulted in slightly poor overall survival in the esophageal carcinoma (P = 0.074) and colon adenocarcinoma (P = 0.080) patients (Fig. 3A).
