For instance, microRNA-216b-inhibited cyclin T2 promoted tumor development and facilitated cell cycle progression of gastric cancer [23], and Wang et al. [24] suggested that MiRNA-188-5p hindered tumor growth and metastasis of osteosarcoma through binding to the 3ʹ-UTR of CCNT2. The gene discussed is CCNT2; the disease is neoplasm.
