Interestingly, we also noticed that the expression of Rack1 gene has been identified with significant upregulation in SHH, WNT, and Type 3 MB tumor samples, but reduction in Type 4 MB tissues based on gene profiling assay using Gene Expression Omnibus (GEO) DataSet (GSE124814) (Figure S4), which was in agreement with our immunostaining results (Figure 1). This evidence concerns the gene RACK1 and neoplasm.
