HIF1A and cancer: The bioinformatic analysis showed that the proteins associated with SP1, MYC, and HIF1A were specifically involved in the regulation of transcription and that various microRNAs (miRNAs) that had been shown to induce either anti- or procancer activity were associated with SP1, MYC, and HIF1A, which suggested that the inhibition of SP1, MYC, and HIF1A could modulate the transcription of both coding and noncoding RNAs and affect cancers.
