AXL and neoplasm: To investigate whether Axl mRNA levels correlated with miR-34a or miR-34c expression in RCC tumors, RT-qPCR was used to measure the three miRNA-family members in RCC tumor tissue (N = 198), and in kidney cortex tissue (N = 50) and compared to Axl mRNA expression data from the same cohort, which has previously been reported [10] (Table 1).
