Moreover, the viability of glioma cells is partly under the control of miR-20a97, while purple sweet potato delphinidin-3-rutin regulates the regulatory function of miR-20b-5p through the protein kinase B (AKT)/Creb/miR-20b-5p/Atg7 pathway98. The gene discussed is AKT1; the disease is central nervous system cancer.
