Although reduced levels of CFIm 25 have been linked to 3′ UTR shortening and increased tumorigenicity of glioblastoma cells [11], once we applied a threshold on the RNA integrity in the samples to be analyzed, CFIm 25 expression was similar between tumors and normal tissue samples (Additional file 1: Figure S3). The gene discussed is CPSF6; the disease is glioblastoma.
