(Submitter supplied) Accumulating evidence indicate that aberrantly increased ribosome biogenesis is a hallmark of cancer. As such, there is a growing interest in the development of strategies to target this pathway for cancer therapeutic. It is well established that inhibition of any steps of ribosome biogenesis induces a nucleolar stress characterized by p53 activation and subsequent cell cycle arrest and/or cell death. more...

(Submitter supplied) Myriad of craniofacial disorders are caused by heterozygous mutations in general regulators of housekeeping cellular functions such as ribosome biogenesis. While it is understood that many of these highly tissue-specific malformations are a consequence of defects in cranial neural crest cells (cNCCs), an embryonic cell group that gives rise to most of the facial structures during embryogenesis, the mechanism underlying cell type-selectivity of these effects remains largely unknown. more...

(Submitter supplied) The role of ribosome biogenesis in erythroid development is supported by the recognition of erythroid defects in ribosomopathies in both Diamond-Blackfan anemia and 5q- syndrome. Whether ribosome biogenesis exerts a regulatory function on normal erythroid development is still unknown. In the present study, a detailed characterization of ribosome biogenesis dynamics during human and murine erythropoiesis shows that ribosome biogenesis is abruptly interrupted by the drop of rDNA transcription and the collapse of ribosomal protein neo-synthesis. more...

(Submitter supplied) The transcription factor p53 exerts its tumor suppressive effects through transcriptional activation of numerous target genes controlling cell cycle arrest, apoptosis, cellular senescence and DNA repair. In addition, there is evidence that p53 influences the translation of specific mRNAs, including translational attenuation of ribosomal protein synthesis and translational activation of MDM2. A challenge in the analysis of translational control is that changes in mRNA abundance exert a kinetic (passive) effect on ribosome densities. more...

(Submitter supplied) In all domains of life, the rate of protein synthesis is directly linked to the rates of cell growth and proliferation. Consequently, highly proliferative cancer cells are especially sensitive to perturbations in ribosome biogenesis. While ribosome synthesis and cancer have a well-established relationship, only recently has ribosome biogenesis drawn interest as a cancer therapeutic target. Here, we have exploited the relationship between ribosome biogenesis and cancer cell proliferation by using a potent ribosome biogenesis inhibitor: RBI2 (Ribosome Biogenesis Inhibitor 2) to perturb cancer cell growth and viability.  We demonstrate that RBI2 significantly decreases cell viability in malignant melanoma cells and breast cancer cell lines. more...

(Submitter supplied) Loss of the tumor suppressor APC, which constitutes the initiating event in the adenoma carcinoma sequence for colorectal cancer (CRC), induces expression of RNA polymerase I (RNAPOL1) transcription machinery and subsequently upregulates rDNA transcription. Targeting RNAPOL1 with a specific inhibitor, CX5461, disrupts nucleolar integrity and induces a disbalance of ribosomal proteins. CX5461-induced growth arrest is irreversible, and exhibits features of senescence as well as terminal differentiation. more...

(Submitter supplied) Tumours depend on altered rates of protein synthesis for growth and survival, suggesting that mechanisms controlling mRNA translation may be exploitable for therapy. Here, we show that loss of APC, which occurs almost universally in colorectal tumours, strongly enhances the dependence on the translation initiation factor eIF2B5. Depletion of eIF2B5 induces an integrated stress response and enhances translation of MYC via an internal ribosomal entry site. more...

(Submitter supplied) Ribonucleotides serve important cellular functions as energy carriers, signaling molecules and building blocks of RNA. In eukaryotes, rRNA and tRNA synthesis in the nucleolus accounts together for over 90% of all RNA molecules. In many cancers, high proliferation rates correlated with elevation of rRNA and tRNA levels4 and nucleolar hypertrophy. However, the metabolic changes that lead to the increased nucleolar transcription and in turn foster tumorigenesis are incompletely understood. more...

(Submitter supplied) Nucleolar stress (NS) kills cells by p53-dependent and independent manners. To investigate the mechanisms of p53-indendendent toxicity, we here used (PR)n arginine-rich peptides as inducers of NS, which are found in patients of some neurodegenerative diseases. Although these peptides generate NS, how this translates to toxicity is poorly understood. We here reveal that whereas (PR)n expression leads to an overall decrease in protein abundance for the majority of the proteome, this occurs concomitant to an accumulation of free ribosomal proteins in the cytoplasm, which is a hallmark of ribosomopathies. more...
