Through employing the sophisticated technique of Cox regression analysis, it has been established that elevated levels of RAB3B serve as detrimental risk factors influencing overall survival in numerous tumor classifications such as CESC, HNSC, KIRC, LUAD, MESO, SARC, STAD, and UVM, thus elucidating its significance as a potent biomarker within cancer scientific inquiry (Fig. 7A). The gene discussed is RAB3B; the disease is cancer.
