CNBP and gastric cancer: Moreover, Yang et al. discovered that circHuR (hsa_circ_0049027), a circular RNA derived from 3 to 5 exons of HuR, was able to bind to CCHC-type zinc finger nucleic acid-binding protein (CNBP) and inhibited its interaction with the HuR promoter, leading to the decrease in HuR expression and the inhibition of gastric cancer advancement [94].
