Qin et al. (2018) also showed that downregulation of MIR31HG inhibited the proliferation of lung adenocarcinoma cells and blocked the G0/G1 to S-phase transition in cell cycle progression, but had no effect on cell apoptosis. In psoriasis, the silencing of lncRNA MIR31HG induced cell cycle arrest in the G2/M phase potentially via the mediation of siRNA (Gao et al., 2018). The gene discussed is MIR31HG; the disease is psoriasis.
