Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

FEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...

Direct Regulation of Hsp60 Expression by C-Myc Induces Transformation

, 2009
The c-MYC proto-oncogene encodes a ubiquitous transcription factor involved in cell proliferation and tumorigenesis. Heat shock protein 60 ( HSP60) plays an essential role in assisting many newly synthesized proteins to reach their native forms ...

MYC and N-MYC are overexpressed in MYC-ER and N-MYC-ER-expressing cells, and naturally overexpressed MYC controls circadian gene expression.

, 2023
A.MYCN was determined in parental SKNAS, SKNAS N-MYC-ER, or SHEP N-MYC-ER by qPCR in n = 3 replicates by quantitative PCR (qPCR), normalized to β2M. MYCN overexpression is shown relative to parental SKNAS, since SHEP do not express MYCN. B.

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Positive and negative regulation of Myc-mediated transcription [PDF]

, 2008
The aim of this thesis has been focused to analyze the positive regulation of Myc-mediated transcription by P-TEFb elongation complex, and the negative control exerted by p14ARF onco-suppressor on Myc's transactivation functions.

PA2G4 Functions as a Cofactor for MYC Family Oncoproteins in MYC-Driven Malignancies

Cells
MYCN and c-MYC are critical driver oncogenes in several childhood cancers, including neuroblastoma. Currently, the clinical development of MYC inhibitors has been hindered by the intrinsically disordered structure of MYC proteins, which lack well-defined

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

AID Is Required for the Chromosomal Breaks in c-myc that Lead to c-myc/IgH Translocations [PDF]

Cell, 2008
Chromosomal translocation requires formation of paired double-strand DNA breaks (DSBs) on heterologous chromosomes. One of the most well characterized oncogenic translocations juxtaposes c-myc and the immunoglobulin heavy-chain locus (IgH) and is found in Burkitt's lymphomas in humans and plasmacytomas in mice.

Asparagine sustains cellular proliferation and c-Myc expression in glutamine-starved cancer cells

, 2021
During tumorigenesis, oncogene activation and metabolism rewiring are interconnected. Activated c-Myc upregulates several genes involved in glutamine metabolism, making cancer cells dependent on high levels of this amino acid to survive and proliferate ...
