c-Myc induced changes in higher order rDNA structure accompany growth factor stimulation of quiescent cells [PDF]

, 2007
Human c-Myc is believed to be a high level coordinator of protein synthesis capacity and cell growth rate, capable of activating transcription by all three nuclear RNA Polymerases.

The nucleolar RNA methyltransferase Misu (NSun2) is required for mitotic spindle stability [PDF]

, 2009
Myc-induced SUN domain–containing protein (Misu or NSun2) is a nucleolar RNA methyltransferase important for c-Myc–induced proliferation in skin, but the mechanisms by which Misu contributes to cell cycle progression are unknown.

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

Western Blot for c-MYC

, 2020
Western blot analysis was performed according to standard procedures. The primary antibodies used were anti-c-Myc (Abcam ab32072) and anti-GAPDH (Santa Cruz sc47724), each at a dilution of 1:1000.

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

DNA-dependent protein kinase catalytic subunit modulates the stability of c-Myc oncoprotein

Molecular Cancer, 2008
Background C-Myc is a short-lived oncoprotein that is destroyed by ubiquitin-mediated proteolysis. Dysregulated accumulation of c-Myc commonly occurs in human cancers. Some of those cases with the dysregulated c-Myc protein accumulation are attributed to

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.

PAK1 activation drives divergent resistance mechanisms to aromatase inhibition and tamoxifen in a luminal: A breast cancer model

Molecular Oncology, EarlyView.
Breast cancer remains a major cause of cancer death in women, frequently developing endocrine therapy resistance. This study demonstrates that upregulated p21‐activated kinase 1 (PAK1) activity drives resistance to tamoxifen and long‐term estrogen deprivation in ER+ breast cancer models.

Nucleolar localization of hepatic c-Myc: a potential mechanism for c-Myc regulation

Biochimica et Biophysica Acta (BBA) - Molecular Cell Research, 2005
The c-myc proto-oncogene encodes a transcription factor that is involved in cell proliferation, growth, differentiation, and apoptosis. Previous studies on the regulation of hepatic c-myc have focused on control of its mRNA expression, which generally correlates with hepatocyte proliferation during both liver development and liver regeneration. However,

SCP1 regulates c-Myc stability and functions through dephosphorylating c-Myc Ser62 [PDF]

Oncogene, 2015
Serine 62 (Ser62) phosphorylation affects the c-Myc protein stability in cancer cells. However, the mechanism for dephosphorylating c-Myc is not well understood. In this study, we identified carboxyl-terminal domain RNA polymerase II polypeptide A small phosphatase 1 (SCP1) as a novel phosphatase specifically dephosphorylating c-Myc Ser62.
