For example, the lncRNA Ras suppressor protein 1 pseudogene 2 (RSU1P2) was shown to be overexpressed in cervical cancer and to play a tumor-promoting role by acting as a ceRNA for microRNA let-7a and regulating the expression of IGF1R, N-myc, and EphA4 [29]. This evidence concerns the gene IGF1R and cervical carcinoma.
