As illustrated in Fig. 3f and Table 1, the expression levels of miR-199b-5p (green fluorescence) were attenuated with the increase of Gleason scores and the lowest in metastatic PCa, while the corresponding DDR1 expression levels (red fluorescence) in the same tissue section were enhanced with Gleason score increases and highest in metastatic disease. The gene discussed is DDR1; the disease is metastatic neoplasm.
