MPZL1 and central nervous system cancer: To explore the mechanism by which MPZL1 promotes cell invasion and migration, bulk RNA-seq data of glioma samples from the CGGA (693 & 325) database were ranked according to the expression level of MPZL1, and the median was used as the cut-off point to divide the samples into the high-MPZL1 group and the low-MPZL1 group.
