USP16 regulates castration-resistant prostate cancer cell proliferation by deubiquitinating and stablizing c-Myc

Journal of Experimental & Clinical Cancer Research, 2021
Background c-Myc, a well-established oncogene, plays an important role in the initiation and progression of various cancers, including prostate cancer. However, its mechanism in cancer cell remains largely unknown and whether there exist a deubiquitinase

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Nucleophosmin interacts directly with c-Myc and controls c-Myc-induced hyperproliferation and transformation [PDF]

Proceedings of the National Academy of Sciences, 2008
The transcription factor c-Myc is essential for cellular proliferation and is one of the most frequently activated oncogenes, but the molecular mechanism mediating its critical role in transformation is unclear. Like c-Myc, multifunctional nucleophosmin (NPM) is tightly regulated during proliferation and is overexpressed in several different types of ...

c-Myc regulates transcriptional pause release

Cell, 2010
Recruitment of the RNA Polymerase II (Pol II) transcription initiation apparatus to promoters by specific DNA binding transcription factors is well recognized as a key regulatory step in gene expression. We report here that promoter-proximal pausing is a

Profiling neoadjuvant therapy response in rectal cancer using meta‐analysis of publicly available transcriptomic RNA‐seq datasets

Molecular Oncology, EarlyView.
This study integrates publicly available transcriptomic datasets to identify molecular signatures associated with response to neoadjuvant chemoradiotherapy in locally advanced rectal cancer. By analyzing a combination of multiple cohorts with bioinformatics approaches, we reveal biological pathways and immune‐related features that may improve ...

Glutathione Depletion Induced by c-Myc Downregulation Triggers Apoptosis on Treatment with Alkylating Agents

Neoplasia: An International Journal for Oncology Research, 2004
Here we investigate the mechanism(s) involved in the c-Myc-dependent drug response of melanoma cells. By using three M14-derived c-Myc low-expressing clones, we demonstrate that alkylating agents, cisplatin and melphalan, trigger apoptosis in the c-Myc ...

Dual targeting of p53 and c-Myc selectively eliminates leukaemic stem cells

Nature, 2016
Chronic myeloid leukaemia (CML) arises after transformation of a haemopoietic stem cell (HSC) by the protein-tyrosine kinase BCR–ABL. Direct inhibition of BCR–ABL kinase has revolutionized disease management, but fails to eradicate leukaemic stem cells ...

The VHL tumor suppressor at the crossroad of protein folding, aggregation, and cancer

Molecular Oncology, EarlyView.
Mutations, environmental stress, and chaperone dysfunction can destabilize pVHL, promoting its conversion from the native folded state into amyloid‐like assemblies. This transition may contribute to protein storage, cell dormancy, survival, and drug resistance.

APOBEC3 activity and DNA polymerase‐ε deficiency are associated with distinct IDH1 R132 hotspot mutations

Molecular Oncology, EarlyView.
Isocitrate dehydrogenase 1 (IDH1) mutations are highly recurrent in multiple human cancer types, including cholangiocarcinoma and glioma. IDH1 R132C is the most common IDH1 mutation in cholangiocarcinoma and likely arises from APOBEC3A‐ or APOBEC3B‐mediated deamination.

Novel Indolocarbazole Derivative 12-(α-L-arabinopyranosyl)indolo[2,3-a]pyrrolo[3,4-c]carbazole-5,7-dione Is a Preferred c-Myc Guanine Quadruplex Ligand

Journal of Nucleic Acids, 2011
The indolocarbazole derivative 12-(α-L-arabinopyranosyl)indolo[2,3-a]pyrrolo[3,4-c]carbazole-5,7-dione (AIC) has demonstrated a high potency (at nanomolar to submicromolar concentrations) towards the NCI panel of human tumor cell lines and transplanted ...
