described piR-30188 as part of the PIWIL3/OIP5-AS/miR-367-3p/CEBPA pathway, which is downregulated in gliomas, and its overexpression together with overexpression of PIWIL3 and miR-367-3p lead to inhibition of glioma cell progression (16). The gene discussed is CEBPA; the disease is central nervous system cancer.
