To characterize and better understand the role of midkine (MDK) in gliomas, we downloaded uniformly processed RNA-Seq abundance values from recount-brain, a curated repository for human brain RNA-Seq datasets, for four different uniformly processed datasets of adult gliomas and healthy brain tissue controls: 643 glioma samples from the cancer genome atlas (TCGA), 268 glioma samples from Chinese glioma genome atlas (CGGA), 93 glioma samples from SRP044668 and 48 glioma samples from ERP010930. This evidence concerns the gene MDK and cancer.
