Bidirectional promoters are the major source of gene activation-associated
noncoding RNA (ncRNA). PC12 cells offer an interesting model for understanding
the mechanism underlying bidirectional promoter-mediated cell cycle control.
Nerve growth factor (NGF)-stimulated PC12 cells elongate neurites, and are in a
reversible cell-cycle-arrested state. In contrast, these cells irreversibly
differentiate and cannot re-enter the normal cell cycle after NGF plus cAMP
treatment. In this study, using directional RNA-seq, we found that bidirectional
promoters for protein-coding genes with promoter-associated ncRNA (pancRNA) were
enriched for cAMP response element consensus sequences, and were preferred
targets for transcriptional regulation by the transcription factors in the
cAMP-dependent pathway. A spindle-formation-associated gene, Nusap1 and
pancNusap1 were among the most strictly co-transcribed pancRNA-mRNA pairs. This
pancRNA-mRNA pair was specifically repressed in irreversibly differentiated PC12
cells. Knockdown (KD) and overexpression experiments showed that pancNusap1
positively regulated the Nusap1 expression in a sequence-specific manner, which
was accompanied by histone acetylation at the Nusap1 promoter. Furthermore,
pancNusap1 KD recapitulated the effects of cAMP on cell cycle arrest. Thus, we
conclude that pancRNA-mediated histone acetylation contributes to the
establishment of the cAMP-induced transcription state of the Nusap1 locus and
contributes to the irreversible cell cycle exit for terminal differentiation of
PC12 cells.
