For example, LUCAT1 activated by STAT3 modulates hepatoblastoma by sponging miR‐301b and regulating STAT3 expression.24 LUCAT1 affects chemoresistance in osteosarcoma by targeting miR‐200c/ABCB1 axis.25 In our study, we found LUCAT1 mainly located in the cytoplasm and therefore conjectured LUCAT1 as a ceRNA to control the progression of CM. Here, LUCAT1 is linked to osteosarcoma.
