We have recently demonstrated that the transcription factor MYB can modulate
several cancer-associated phenotypes in pancreatic cancer. In order to understand
the molecular basis of these MYB-associated changes, we conducted deep-sequencing
of transcriptome of MYB-overexpressing and -silenced pancreatic cancer cells,
followed by in silico pathway analysis. We identified significant modulation of
774 genes upon MYB-silencing (p?0.05) that were assigned to 25 gene networks by
in silico analysis. Further analyses placed genes in our RNA sequencing-generated
dataset to several canonical signalling pathways, such as cell-cycle control,
DNA-damage and -repair responses, p53 and HIF1?. Importantly, we observed
downregulation of the pancreatic adenocarcinoma signaling pathway in MYB-silenced
pancreatic cancer cells exhibiting suppression of EGFR and NF-?B. Decreased
expression of EGFR and RELA was validated by both qPCR and immunoblotting and
they were both shown to be under direct transcriptional control of MYB. These
observations were further confirmed in a converse approach wherein MYB was
overexpressed ectopically in a MYB-null pancreatic cancer cell line. Our findings
thus suggest that MYB potentially regulates growth and genomic stability of
pancreatic cancer cells via targeting complex gene networks and signaling
pathways. Further in-depth functional studies are warranted to fully understand
MYB signaling in pancreatic cancer.
