Figure 1From: Target competition: transcription factors enter the limelightTarget competition: a multi-layered regulatory mechanism. mRNAs crosstalk through miRNA sequestration resulting in co-expression. In addition, transcription factor mRNAs are translated into transcription factor proteins that can be competed for by transcription factor binding sites in promoters. Moreover, the target genes of such transcription factors are transcribed into RNA transcripts that may also participate in ceRNA crosstalk. TF, transcription factor.Back to article page
