RAB37 and lung adenocarcinoma: We found that exhaustion T cell (Tex) gene signatures showed a stronger positive correlation with Rab37 compared to Rab3a, Rab8a or Rab11b in patients with lung adenocarcinoma (n = 483) and lung squamous cell carcinoma (n = 486) datasets (Fig. 1A–D) from the Gene Expression Profiling Interactive Analysis (GEPIA) website [19].
