IGF1R, as an indispensable player in SCLC [28–30], was further confirmed as the only common target of miR-377-3p and miR-494-3p, evidenced by that the IGF1R mRNA level was significantly decreased or increased upon the transfection of miR-377-3p/miR-494-3p mimics or inhibitors, respectively (Fig. S4). Here, IGF1R is linked to small cell lung carcinoma.
