A miR-1305 mimic and a miR-1305 inhibitor were transfected into GC cells to overexpress and knockdown miR-1305, respectively, and theqRT-PCR data showed that the expression of JAK1 and STAT1 was downregulated when miR-1305 was overexpressed, and the expression of JAK1 and STAT1 was upregulated when miR-1305 was knocked down (Figure 7B). This evidence concerns the gene JAK1 and gastric cancer.
