PLAT and gastrointestinal stromal tumor: The relative expression of the three circRNAs (circ_0069765, circ_0079471 and circ_0084097) was evidently upregulated in the GIST tissues compared with that in the adjacent noncancerous tissues (p < 0.001); in addition, the three host genes, i.e., KIT, PLAT and ETV1, were upregulated (p < 0.001) (Figure 4).
