Studies by Dong et al. [10] on circRNA nuclear receptor-interacting protein 1 (CircRNA NRIP1) has been published in which they describe that CircRNA NRIP1 may work as a carcinogene to facilitate the development of renal carcinoma via sponging miR-505 by motivating the AMPK and PI3K/AKT/mTOR pathways. Here, NRIP1 is linked to renal carcinoma.
