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

Therapeutic Potential of the Cyclin-Dependent Kinase Inhibitor Flavopiridol on c-Myc Overexpressing Esophageal Cancer

Frontiers in Pharmacology, 2021
Tumors with elevated c-Myc expression often exhibit a highly aggressive phenotype, and c-Myc amplification has been shown to be frequent in esophageal cancer.

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.

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

Nucleophosmin is essential for c-Myc nucleolar localization and c-Myc-mediated rDNA transcription [PDF]

Oncogene, 2012
The transcription factor c-Myc has a critical role in cell proliferation and growth. The control of ribosome biogenesis by c-Myc through the regulation of transcription mediated by all three RNA polymerases is essential for c-Myc-driven proliferation. Specifically, in the nucleolus, c-Myc has been shown to be recruited to ribosomal DNA and activate RNA

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.

c-Myc Inhibition Induces an Additive Effect with Cyclophosphamide in Acute Lymphoblastic Leukemia [PDF]

ImmunoAnalysis
Background: Cellular-myelocytomatosis (c-Myc), an oncoprotein and a transcription factor, is involved in several essential cellular processes. The c-Myc expression level is highly regulated in normal cells.

Domain-specific c-Myc ubiquitylation controls c-Myc transcriptional and apoptotic activity [PDF]

Proceedings of the National Academy of Sciences, 2012
The oncogenic transcription factor c-Myc causes transformation and tumorigenesis, but it can also induce apoptotic cell death. Although tumor suppressors are necessary for c-Myc to induce apoptosis, the pathways and mechanisms are unclear.

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.

Additional file 2 of Ring finger protein 180 suppresses cell proliferation and energy metabolism of non-small cell lung cancer through downregulating C-myc

, 2022
Additional file 2: Figure S2. RNF180 silencing contributed to the expression of C-myc through inhibiting its ubiquitination. A and B. Western blot was used to examine the protein level of C-myc in siNC and siRNF180 transfecting H292 and A549 with or ...
