TranscriptomicsOncogenic Myc levels activate and repress specific genes to form characteristic expression profiles in human tumors
Myc was depleted in HeLa cells (ATCC CRL-1934) with an shRNA and the resulting expression profile changes mapped via microarrays. This study is the equivalent of E-MTAB-1524 . E-MTAB-1524 has been replaced by E-MTAB-1886.

GenomicsAnalysis of MIZ1, MYC-ER and MYC-ERVD binding sites in MCF10A cells
Oncogenic levels of Myc expression sensitize cells to multiple apoptotic stimuli and this protects long-lived organisms from cancer development. How cells discriminate physiological from supra-physiological levels of Myc is largely unknown. Here we show that induction of apoptosis by Myc in breast e...

GenomicsBIM is the primary mediator of MYC-induced apoptosis in multiple solid tissues
C-MYC (henceforth MYC) is one of the most frequently overexpressed oncogenes in human cancer and even modestly deregulated MYC expression can initiate ectopic proliferation in many post-mitotic, terminally differentiated cell types in vivo. Metazoan organisms have consequently evolved a number of me...

GenomicsActivation and repression by oncogenic Myc shapes tumour-specific gene expression profiles
In mammalian cells, the Myc oncoprotein binds to thousands of promoters. During mitogenic stimulation of primary lymphocytes, Myc promotes an increase in expression of virtually all genes. In contrast, Myc-driven tumour cells differ from normal cells in expression of specific sets of up- and downreg...
