Functional assays suggested that inhibition of these three circular RNAs (hsa_circ_0047905, hsa_circ_0138960 and hsa-circRNA7690-15) suppresses GC cell proliferation and invasion in vitro.
Analysis of co-expression networks for circular RNAs and mRNAs reveals that circular RNAs hsa_circ_0047905, hsa_circ_0138960 and has-circRNA7690-15 are candidate oncogenes in gastric cancer.
