POU2F1 and glioblastoma: The second promoter region was linked with 6 of the GBM48 panel’s genes which contained the CWNAWTKWSATRYN motif for the POU2F1 transcription factor (also known as Oct-1, FDR-adjusted p-value of 4.73 x 10^-4), which has been shown to be differentially expressed in human glioblastoma cells [31,32].
