Ribosomal DNA-connecting ribosome biogenesis and chromosome biology [PDF]

Chromosome Research, 2019
Ribosomal DNA, the topic of this special issue, has long fascinated biologists. The RNA products of the ribosomal DNA are the ribosomal RNAs that are part of the ribosome. In this special issue, we focus on the sequence, molecular organization, repair, stability, copy number, and peculiar genetics of this region of the genome.

Inhibiting eukaryotic ribosome biogenesis: Mining new tools for basic research and medical applications

Microbial Cell, 2019
The formation of new ribosomes is a fundamental cellular process for each living cell and is tightly interwoven with cell cycle control and proliferation.

Genome-Scale CRISPR Screening Reveals Host Factors Required for Ribosome Formation and Viral Replication

mBio, 2023
Viruses are known to co-opt host machinery for translation initiation, but less is known about which host factors are required for the formation of ribosomes used to synthesize viral proteins.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

Molecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

The Effects of Deregulated Ribosomal Biogenesis in Cancer

Biomolecules, 2023
Ribosomes are macromolecular ribonucleoprotein complexes assembled from RNA and proteins. Functional ribosomes arise from the nucleolus, require ribosomal RNA processing and the coordinated assembly of ribosomal proteins (RPs), and are frequently hyperactivated to support the requirement for protein synthesis during the self-biosynthetic and metabolic ...

Arginine methylation as a regulatory ratchet in cancer: From substrate selection to malignant‐state stabilization

Molecular Oncology, EarlyView.
Arginine methylation can be viewed as a persistence‐prone post‐translational modification regulated by a network of PRMTs. Competitive and compensatory interactions among PRMTs can redistribute methylation across substrate pools shaped by sequence, structural, spatial, and environmental layers, reinforcing RNA‐processing, chromatin, and signaling ...

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.

When ribosomes go bad: diseases of ribosome biogenesis [PDF]

Molecular BioSystems, 2010
Abstract Ribosomes are vital for cell growth and survival. Until recently, it was believed that mutations in ribosomes or ribosome biogenesis factors would be lethal, due to the essential nature of these complexes. However, in the last few decades, a number of diseases of ribosome biogenesis have been discovered.

Fibrillarin-mediated ribosomal RNA maturation is a novel therapeutic vulnerability in triple-negative breast cancer

Breast Cancer Research
Background Triple-negative breast cancer (TNBC) remains one of the most challenging breast cancer subtypes to treat due to the lack of effective therapeutic options.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.
