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 E-MTAB-1524 has been replaced by E-MTAB-1886.

TranscriptomicsThe MYC-MIZ1 interaction defines tumor identity
Medulloblastoma (MB) is the most common malignant brain tumor. MB is a cerebellar tumor that occurs mostly in children between the ages of 3-7 years but also in adults. Human MBs are classified into four subgroups: Wingless (WNT), Sonic Hedgehog (SHH), Group 3 (G3) and G4, each of which with distinc...

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...

TranscriptomicsMyc and N-myc induce distinct medulloblastoma subgroups via Miz1
Medulloblastomas (MBs) are cerebellar tumors that can be classified into molecularly distinct subgroups that differ in pathology and prognosis. The mechanisms that underlie subgroup specification are largely unknown. While human SHH MBs express MYCN, Group3 (G3) MBs are associated with c-MYC (MYC) o...

TranscriptomicsMyc and Miz-1 control melanocyte senescence by regulating intracellular cystathionase levels
The development of malignant melanoma is a highly complex process which is still poorly understood despite extensive research. A majority of human melanomas are found to express a handful of oncogenic proteins, such as mutant RAS and BRAF. However, these oncogenes are also found in nevi, and it is n...

TranscriptomicsTumor cell-specific inhibition of MYC function using small molecule inhibitors of the HUWE1 ubiquitin ligase
Deregulated expression of MYC is a driver of colorectal carcinogenesis, necessitating novel strategies to inhibit MYC function. The ubiquitin ligase HUWE1 (HECTH9, ARFBP1, MULE) associates with both MYC and the MYC-associated protein MIZ1. We show here that HUWE1 is required for growth of colorecta...

TranscriptomicsUbiquitin-dependent turnover of MYC promotes loading of the PAF complex on RNA Polymerase II to drive transcriptional elongation (RNA-seq)
The MYC transcription factor is an unstable protein and its turnover is controlled by the ubiquitin system. Ubiquitination enhances MYC-dependent transactivation, but the underlying mechanism remains unresolved. Here we show that proteasomal turnover of MYC is dispensable for recruitment of RNA poly...
