Abstract:
Genomic regulation and functional significance of PVT-1 gene locus, in the MYC-driven cancers, has remained enigmatic ever since its discovery. With the present study, an attempt is made to establish that cellular AATF genome encoded miR-2909 RNomics pathway involving crucial genes coding for KLF4, Deptor, mTORC1, STAT3, and p53 has the inherent capacity to ensure sustained co-amplification of PVT-1 gene locus together with c-Myc gene. Based upon these results, we propose that miR-2909 RNomics pathway may play a crucial role in the regulation of tumorigenic PVT-1 gene locus.
