Because in some cases, lncRNAs function by regulating their gene neighbors28–30, we first tested whether TP73-AS1 may regulate the expression of its gene neighbor, TP73. We found that this is not the case, as there is no correlation in expression between the two genes in G26, in a collection of mammalian cell lines and in two independent GBM cohorts. The gene discussed is TP73; the disease is glioblastoma.
