As shown in Figure 3B and 3C, non-GSCs glioma cells displayed significantly lower HuR protein levels than GSCs, while let-7b level showed no significant change between GSCs and non-GSCs glioma cells, which suggested that downregulation of lincRNA-p21 in GSCs might result from upregulation of HuR expression. This evidence concerns the gene ELAVL1 and glioma.
