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

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.

The Expression and Localization of N-Myc Downstream-Regulated Gene 1 in Human Trophoblasts [PDF]

, 2013
The protein N-Myc downstream-regulated gene 1 (NDRG1) is implicated in the regulation of cell proliferation, differentiation, and cellular stress response.

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.

Distinct functions of transforming growth factor-β signaling in c-MYC driven hepatocellular carcinoma initiation and progression

Cell Death and Disease, 2021
Dysregulation of transforming growth factor-beta (TGFβ) signaling has been implicated in liver carcinogenesis with both tumor promoting and inhibiting activities.

Direct Activation of HSP90A Transcription by c-Myc Contributes to c-Myc-induced Transformation [PDF]

Journal of Biological Chemistry, 2004
The c-myc proto-oncogene encodes a ubiquitous transcription factor involved in the control of cell growth and differentiation and implicated in inducing tumorigenesis. Understanding the function of c-Myc and its role in cancer depends upon the identification of c-Myc target genes.

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.

A novel mechanism by which c-MYC is aberrantly activated by epigenetic silencing of its antisense lncRNA in colon cancer

Frontiers in Genetics
BackgroundProto-oncogenes are abnormally activated in nearly all types of tumors. However, the epigenetic mechanism of proto-oncogene activation has not yet been well elucidated.MethodsThe present study involved the construction of a double-stranded cDNA
