Abstract
Pescadillo ribosomal biogenesis factor 1 (PES1), a nucleolar protein initially identified in zebrafish, plays an important role in embryonic development and ribosomal biogenesis. Notably, PES1 has been found to be overexpressed in a number of cancer types, where it contributes to tumorigenesis and cancer progression by promoting cell proliferation, suppressing cellular senescence, modulating the tumor microenvironment (TME) and promoting drug resistance in cancer cells. Moreover, recent emerging evidence suggests that PES1 expression is significantly elevated in the livers of Type 2 diabetes mellitus (T2DM) and obese patients, indicating its involvement in the pathogenesis of metabolic diseases through lipid metabolism regulation. In this review, we present the structural characteristics and biological functions of PES1, as well as complexes in which PES1 participates. Furthermore, we comprehensively summarize the multifaceted role of PES1 in various diseases and the latest insights into its underlying molecular mechanisms. Finally, we discuss the potential clinical translational perspectives of targeting PES1, highlighting its promising as a therapeutic intervention and treatment target.

Abstract
The impact of innovative technologies on the target discovery has been employed here to characterize the interactome of STIRUR 41, a promising 3-fluoro-phenyl-5-pyrazolyl-urea derivative endowed with anti-cancer activity, on neuroblastoma-related cells. A drug affinity responsive target stability-based proteomic platform has been optimized to elucidate the molecular mechanism at the basis of STIRUR 41 action, together with immunoblotting analysis and in silico molecular docking. Ubiquitin Specific Protease 7 (USP-7), one of the deubiquitinating enzymes which protect substrate proteins from proteasomal degradation, has been identified as the most affine STIRUR 41 target. As further demonstrated by in vitro and in-cell assays, STIRUR 41 was able to inhibit both the enzymatic activity of USP-7 and its expression levels in neuroblastoma-related cells, thus laying an encouraging base for the blockade of USP-7 downstream signaling.

MYCN Amplification Is Associated with Reduced Expression of Genes Encoding γ-Secretase Complex and NOTCH Signaling Components in Neuroblastoma. Int J Mol Sci 2023; 24:8141. [PMID: 37175848 PMCID: PMC10179553 DOI: 10.3390/ijms24098141] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 04/06/2023] [Accepted: 04/26/2023] [Indexed: 05/15/2023] Open
Abstract
Amplification of the MYCN oncogene is found in ~20% of neuroblastoma (NB) cases and correlates with high-risk disease and poor prognosis. Despite the plethora of studies describing the role of MYCN in NB, the exact molecular mechanisms underlying MYCN's contribution to high-risk disease are not completely understood. Herein, we implemented an integrative approach combining publicly available RNA-Seq and MYCN ChIP-Seq datasets derived from human NB cell lines to define biological processes directly regulated by MYCN in NB. Our approach revealed that MYCN-amplified NB cell lines, when compared to non-MYCN-amplified cell lines, are characterized by reduced expression of genes involved in NOTCH receptor processing, axoneme assembly, and membrane protein proteolysis. More specifically, we found genes encoding members of the γ-secretase complex, which is known for its ability to liberate several intracellular signaling molecules from membrane-bound proteins such as NOTCH receptors, to be down-regulated in MYCN-amplified NB cell lines. Analysis of MYCN ChIP-Seq data revealed an enrichment of MYCN binding at the transcription start sites of genes encoding γ-secretase complex subunits. Notably, using publicly available gene expression data from NB primary tumors, we revealed that the expression of γ-secretase subunits encoding genes and other components of the NOTCH signaling pathway was also reduced in MYCN-amplified tumors and correlated with worse overall survival in NB patients. Genetic or pharmacological depletion of MYCN in NB cell lines induced the expression of γ-secretase genes and NOTCH-target genes. Chemical inhibition of γ-secretase activity dampened the expression of NOTCH-target genes upon MYCN depletion in NB cells. In conclusion, this study defines a set of MYCN-regulated pathways that are specific to MYCN-amplified NB tumors, and it suggests a novel role for MYCN in the suppression of genes of the γ-secretase complex, with an impact on the NOTCH-target gene expression in MYCN-amplified NB.

Pescadillo ribosomal biogenesis factor 1 reduction suppresses tumour growth and renders chemosensitivity of head and neck squamous cell carcinoma. Cancer Med 2023; 12:5703-5717. [PMID: 36217758 PMCID: PMC10028059 DOI: 10.1002/cam4.5315] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2022] [Revised: 09/14/2022] [Accepted: 09/20/2022] [Indexed: 11/07/2022] Open
Abstract
BACKGROUND As one of the most devastating cancers, head and neck squamous cell carcinoma (HNSCC) has a short survival time and poor prognosis. Pescadillo ribosomal biogenesis factor 1 (PES1) plays a critical role in the progression of numerous cancers. However, its role and underlying mechanisms in HNSCC remain unclear. METHODS A variety of bioinformatic approaches were used to identify the expressions, prognostic and diagnostic value of PES1 in HNSCC. qRT-PCR, immunofluorescence (IF) assay, western blotting and immunohistochemical (IHC) were used to evaluate the expression of PES1 in HNSCC cell lines and clinical tissues. PES1 was knocked down in TU177 and FaDu cells which have high PES1 expression. The effects of PES1 on cell proliferation and tumour growth in HNSCC were elevated by colony formation, CCK8 assays and tumorigenicity assay in nude mice. The effects on cisplatin (CDDP) sensitivity upon silencing of PES1 were assessed using a patient-derived xenograft (PDX) model. RESULTS PES1 expression was an independent prognostic factor for HNSCC and negatively associated with the overall survival rate. Silencing of PES1 reduces HNSCC cell proliferation and tumour growth. Moreover, PES1 inhibition significantly sensitises HNSCC cells to cisplatin. Furthermore, we found a PES1 has a high correlation with c-Myc and plays an essential role in the tumour immune microenvironment. CONCLUSION Our findings suggest that PES1 is associated with tumour growth and drug resistance and served as a potential cancer marker for diagnosis and a putative therapeutic target for HNSCC.

Abstract
Tumors are neogrowths formed by the growth of normal cells or tissues through complex mechanisms under the influence of many factors. The occurrence and development of tumors are affected by many factors. Pescadillo ribosomal biogenesis factor 1 (PES1) has been identified as a cancer-related gene. The study of these genes may open up new avenues for early diagnosis, treatment and prognosis of tumors. As a nucleolar protein and part of the Pes1/Bop1/WDR12 (PeBoW) complex, PES1 is involved in ribosome biogenesis and DNA replication. Many studies have shown that high expression of PES1 is often closely related to the occurrence, proliferation, invasion, metastasis, prognosis and sensitivity to chemotherapeutics of various human malignant tumors through a series of molecular mechanisms and signaling pathways. The molecules that regulate the expression of PES1 include microRNA (miRNA), circular RNA (circRNA), c-Jun, bromodomain-containing protein 4 (BRD4) and nucleolar phosphoprotein B23. However, the detailed pathogenic mechanisms of PES1 overexpression in human malignancies remains unclear. This article summarizes the role of PES1 in the carcinogenesis, prognosis and treatment of multiple tumors, and introduces the molecular mechanisms and signal transduction pathways related to PES1.

Abstract
Neurological disorders (NLDs) are among the top leading causes for disability worldwide. Dramatic changes in the epigenetic topography of the brain and nervous system have been found in many NLDs. Histone lysine acetylation has prevailed as one of the well characterised epigenetic modifications in these diseases. Two instrumental components of the acetylation machinery are the evolutionarily conserved Bromodomain and PHD finger containing (BRPF) and Bromo and Extra terminal domain (BET) family of proteins, also referred to as acetylation 'readers'. Several reasons, including their distinct mechanisms of modulation of gene expression and their property of being highly tractable small molecule targets, have increased their translational relevance. Thus, compounds which demonstrated promising results in targeting these proteins have advanced to clinical trials. They have been established as key role players in pathologies of cancer, cardiac diseases, renal diseases and rheumatic diseases. In addition, studies implicating the role of these bromodomains in NLDs are gaining pace. In this review, we highlight the findings of these studies, and reason for the plausible roles of all BET and BRPF members in NLDs. A comprehensive understanding of their multifaceted functions would be radical in the development of therapeutic interventions.

Abstract
Neuroblastoma, an embryonic tumor arising from neuronal crest progenitor cells, has been shown to contain a population of undifferentiated stem cells responsible for the malignant state and the unfavorable prognosis. Although many previous studies have analyzed neuroblastoma stem cells and their therapeutic targeting, this topic appears still open to novel investigations. Here we found that neurospheres derived from neuroblastoma stem-like cells showed a homogeneous staining for several key nucleolar proteins, such as Nucleolin, Nucleophosmin-1, Glypican-2 and PES-1. We investigated the effects of Roniciclib (BAY 1000394), an anticancer stem cells agent, on neurospheres and on an orthotopic neuroblastoma mouse model, discovering an impressive inhibition of tumor growth and indicating good chances for the use of Roniciclib in vivo. We demonstrated that Roniciclib is not only a Wnt/β-catenin signaling inhibitor, but also a nucleolar stress inducer, revealing a possible novel mechanism underlying Roniciclib-mediated repression of cell proliferation. Furthermore, we found that high expression of Nucleophosmin-1 correlates with patients’ short survival. The co-expression of several stem cell surface antigens such as CD44v6 and CD114, together with the nucleolar markers here described, extends new possibilities to isolate undifferentiated subpopulations from neuroblastoma and identify new targets for the treatment of this childhood malignancy.

Abstract
Background As a nucleolar protein associated with ribosome biogenesis, pescadillo homolog 1 (PES1) has been reported to participate in the development of many cancers. However, its role in prostate cancer is not clearly defined. Therefore, the aim of this study is to explore the effects and the specific mechanism of PES1 in prostate cancer. Methods A microarray-based analysis was performed to analyze differentially expressed genes (DEGs) between prostate cancer and normal samples. Next, the interaction between PES1 and microRNA-1271 (miR-1271) was investigated using bioinformatics analysis in combination with dual-luciferase reporter gene assay. The expression of miR-1271 in prostate cancer cells and tissues was determined using RT-qPCR. Its effects on downstream estrogen receptor β (ERβ) signaling pathway were further examined. Moreover, we analyzed whether miR-1271 affects proliferation, apoptosis, migration and invasion of prostate cancer cells by EdU assay, flow cytometry, and Transwell assay. Lastly, a prostate cancer mouse model was conducted to measure their roles in the tumor growth. Results PES1 was identified as a prostate cancer-related DEG and found to be upregulated in prostate cancer. miR-1271, which was poorly expressed in both cells and tissues of prostate cancer, can specifically bind to PES1. Additionally, overexpression of miR-1271 activated the ERβ signaling pathway. Overexpression of miR-1271 or depletion of PES1 inhibited prostate cancer cell proliferation, migration and invasion, promoted apoptosis in vitro and suppressed tumor growth in vivo. Conclusions Taken together, overexpression of miR-1271 downregulates PES1 to activate the ERβ signaling pathway, leading to the delayed prostate cancer development. Our data highlights the potential of miR-1271 as a novel biomarker for the treatment of prostate cancer.

Abstract
Purpose Liver cancer has a high incidence of mortality. DNA replication and posttranscriptional modifications play important roles in the development of liver cancer. Pescadillo (PES1) is a nuclear protein that is involved in embryonic development, ribosome synthesis, DNA replication, and cell cycle progression. Recently, abnormal PES1 expression was reported in several tumors, including neuroblastoma, colon cancer, gastric cancer, and breast cancer. Based on bio-informatic analysis, cell experiments and animal models, the aim of this study is to investigate the expression patterns and specific roles of PES1 in liver cancer. Patients and methods PES1 expression was represented by boxplots. The correlation between PES1 expression and clinical features was assessed by the chi-squared test and Fisher's exact tests. Kaplan-Meier curves compared overall survival between different levels of PES1 expression, and Cox analysis selected potential variables associated with overall survival. The MTT assay investigated the proliferation rate, the scratch assay assessed the migratory ability, and the Transwell assay evaluated the invasion capacity of tumor cells in vitro. Animal models were used to confirm the tumorigenic roles of PES1 in vivo. GSEA illustrated the molecular mechanisms that PES1 participated in. Results We found that PES1 was highly expressed in liver cancer tissues, served as a diagnostic marker, and correlated with poor overall survival (OS) and relapse-free survival (RFS) in patients. In vitro studies indicated that PES1 promoted tumor cell proliferation (P=0.0034), migration (P=0.0026), and invasion (P=0.0008), and this tumorigenic role was confirmed in animal models. GSEA further illuminated molecular mechanisms that PES1 participated in liver cancer occurrence and progression. Conclusion This study suggested that PES1 was upregulated in liver cancer and correlated with poor prognosis, by promoting tumor cell proliferation, migration, and invasion, and PES1 may be a novel diagnostic and prognostic bio-marker and a promising therapeutic target in liver cancer.

Abstract
Background Overexpressed PES1 promotes carcinogenesis in various types of malignant tumors. However, the biological role and clinical significance of PES1 in pancreatic cancer are still unexplored. Methods The expression level of PES1 in pancreatic cancer cell lines and pancreatic cancer patient samples was determined using Western Blotting analysis, RT-qPCR analysis, immunohistochemical (IHC) analysis of tissue microarray, and the GEPIA web tool. MTS assay, colony formation assay, and xenograft tumor assay were used to evaluate the tumor growth ability of pancreatic cancer cells. Results We established that the expression of PES1 was abnormally increased in pancreatic cancer tissues and led to poor prognosis of pancreatic cancer patients. We also found that PES1 was responsible for promoting cell growth and contributed to bromodomain and cancer cell resistance to extra-terminal (BET) inhibitors in pancreatic cancer. Furthermore, we showed that PES1 interacted with BRD4 to enhance c-Myc expression, which is the primary cause of cancer cell resistance to BET inhibitors in pancreatic cancer. Finally, CDK5 inhibitors were proven to destabilize PES1 and overcome cancer cell resistance to BET inhibitors in pancreatic cancer cells. Conclusions We have shown that PES1 could be one of the promoting factors of tumor growth and a prognosis-related protein of pancreatic cancer. Targeting PES1 with CDK5 inhibitors might help overcome cancer cell resistance to BET inhibitors in pancreatic cancer cells.

PES1 is a critical component of telomerase assembly and regulates cellular senescence. SCIENCE ADVANCES 2019; 5:eaav1090.

Abstract
Telomerase defers the onset of telomere shortening and cellular senescence by adding telomeric repeat DNA to chromosome ends, and its activation contributes to carcinogenesis. Telomerase minimally consists of the telomerase reverse transcriptase (TERT) and the telomerase RNA (TR). However, how telomerase assembles is largely unknown. Here, we demonstrate that PES1 (Pescadillo), a protein overexpressed in many cancers, forms a complex with TERT and TR through direct interaction with TERT, regulating telomerase activity, telomere length maintenance, and senescence. PES1 does not interact with the previously reported telomerase components Reptin, Pontin, p23, and Hsp90. PES1 facilitates telomerase assembly by promoting direct interaction between TERT and TR without affecting TERT and TR levels. PES1 expression correlates positively with telomerase activity and negatively with senescence in patients with breast cancer. Thus, we identify a previously unknown telomerase complex, and targeting PES1 may open a new avenue for cancer therapy.

[PMID: 30705367 PMCID: PMC6355968 DOI: 10.1038/s41598-018-37648-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Accepted: 12/07/2018] [Indexed: 02/07/2023] Open
Abstract
PES1, a BRCT domain-containing protein, has been shown to play a role in modulating the balance and ratio between ERα and ERβ protein, which is involved in the occurrence and development of breast and ovarian cancer. However, its role in connection with the balance and ratio between ERα and ERβ protein in papillary thyroid cancer (PTC) remains unclear. Here, we found that ERα and ERβ were co-expressed in human PTC tissues and cells. ERα promoted and ERβ inhibited the proliferation, invasion and migration of PTC cells. PES1 modulated the balance between ERα and ERβ by elevating the ERα protein level and simultaneously reducing the ERβ protein level, then upregulating the ERα/ERβ protein ratio and promoting the proliferation, invasion and migration of PTC cells. In PTC tissues, PES1 protein level was positively correlated with the ERα protein level and negatively correlated with the ERβ protein level. The PES1 and ERα protein levels were gradually increased and the ERβ protein level was decreased by degree in the occurrence and development of PTC. Increased PES1 and ERα protein levels and decreased ERβ protein level were correlated with the aggressive behaviors of PTC patients such as large tumor size, extrathyroidal extension (ETE), lymph node metastasis (LNM), high BRAFV600E expression and high TNM stage. It is suggested that PES1 promotes the occurrence and development of PTC by elevating the ERα protein level and reducing the ERβ protein level, and then upregulating the ERα/ERβ protein ratio.

PES1 enhances proliferation and tumorigenesis in hepatocellular carcinoma via the PI3K/AKT pathway. Life Sci 2019; 219:182-189.

Abstract
AIM We investigated the potential role of pescadillo ribosomal biogenesis factor 1 (PES1) in the development of hepatocellular carcinoma (HCC). MATERIAL AND METHODS One hundred and thirty-four patients with hepatocellular carcinoma were chosen to evaluate the association between the expression of PES1 and survival, clinical characteristics of these patients. Western blotting, real-time PCR, immunohistochemistry, CCK-8 assay, colony formation and subcutaneous tumors in nude mice were conducted. KEY FINDINGS We found that PES1 was commonly upregulated in HCC tissues and cells. Immunohistochemical analysis of 134 paraffin-embedded archived HCC tissues showed that the protein expression level of PES1 was positively correlated with clinical characteristics and reduced the survival time of HCC patients. Univariate and multivariate analysis revealed that PES1 expression may be an independent prognostic indicator of poorer overall survival in HCC patients. Furthermore, silencing of endogenous PES1 significantly inhibited the proliferation and tumorigenicity of SMMC 7721 and HepG2 cells in vitro as well as in vivo in nude mice. Finally, we found that PES1 affected cell proliferation by regulating the PI3K/AKT/GSK3β/cyclinD1 signaling pathway. SIGNIFICANCE Our data suggest that PES1 may promote proliferation and tumorigenicity, and potentially representing a novel prognostic marker for overall survival in HCC. CORE TIP We report that pescadillo ribosomal biogenesis factor 1 (PES1) plays an oncogenic role in hepatocellular carcinoma, which was commonly upregulated in hepatocellular carcinoma tissues and cells. Immunostaining analysis found that the protein expression level of PES1 was positively correlated with clinical characteristics and reduced survival time of hepatocellular carcinoma patients. Multivariate analysis revealed that PES1 expression might be an independent prognostic indicator of survival in hepatocellular carcinoma patients. Furthermore, PES1 knockdown inhibited the proliferation and tumorigenesis in hepatocellular carcinoma cell lines. Additionally, we found that PES1 is involved in the cell proliferation by regulating the AKT/GSK3β/cyclinD1 signaling pathway.

Abstract
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related death worldwide. However, the mechanism underlying the tumorigenesis of HCC is still unclear. Improper recruitment of Pescadillo homologue 1 (PES1) can lead to tumorigenesis in multiple cancer types, such as gastric cancer and colon cancer. Here, we reported that PES1 was upregulated and associated with a poor prognosis in HCC specimens. Next, we found that PES1 promoted the growth of HCC in vivo and in vitro. Furthermore, we showed that the knockdown of PES1 decreased glycolysis via altering the gene expression of GLUT1, PKM2, ENO1, FBP1, and PCK1, which are related to glucose metabolism in HCC cells. Moreover, we demonstrated that PES1 is regulated by bromodomain-containing protein 4 (BRD4) and is partially responsible for modulating the antitumor effect of BET inhibitors in HCC. Taken together, our results suggest that PES1 plays an important role in promoting the proliferation of human liver cancer cells, suggesting that PES1 may be an ideal molecular target for HCC therapy.

Abstract
Genomic information from human patient samples of pediatric neuroblastoma cancers and known outcomes have led to specific gene lists put forward as high risk for disease progression. However, the reliance on gene expression correlations rather than mechanistic insight has shown limited potential and suggests a critical need for molecular network models that better predict neuroblastoma progression. In this study, we construct and simulate a molecular network of developmental genes and downstream signals in a 6-gene input logic model that predicts a favorable/unfavorable outcome based on the outcome of the four cell states including cell differentiation, proliferation, apoptosis, and angiogenesis. We simulate the mis-expression of the tyrosine receptor kinases, trkA and trkB, two prognostic indicators of neuroblastoma, and find differences in the number and probability distribution of steady state outcomes. We validate the mechanistic model assumptions using RNAseq of the SHSY5Y human neuroblastoma cell line to define the input states and confirm the predicted outcome with antibody staining. Lastly, we apply input gene signatures from 77 published human patient samples and show that our model makes more accurate disease outcome predictions for early stage disease than any current neuroblastoma gene list. These findings highlight the predictive strength of a logic-based model based on developmental genes and offer a better understanding of the molecular network interactions during neuroblastoma disease progression.

Abstract
PES1 is a component of the PeBoW complex, which is required for the maturation of 28S and 5.8S ribosomal RNAs, as well as for the formation of the 60S ribosome. Deregulation of ribosomal biogenesis can contribute to carcinogenesis. In this study, we showed that PES1 could be modified by the small ubiquitin-like modifier (SUMO) SUMO-1, SUMO-2 and SUMO-3, and SUMOylation of PES1 was stimulated by estrogen (E2). One major SUMOylation site (K517) was identified in the C-terminal Glu-rich domain of PES1. Substitution of K517 with arginine abolished the SUMOylation of PES1. SUMOylation also stabilized PES1 through inhibiting its ubiquitination. In addition, PES1 SUMOylation positively regulated the estrogen signaling pathway. SUMOylation enhanced the ability of PES1 to promote estrogen receptor α (ERα)-mediated transcription by increasing the stability of ERα, both in the presence and absence of E2. Moreover, SUMOylation of PES1 also increased the proportion of S-phase cells in the cell cycle and promoted the proliferation of breast cancer cells both in vitro and in vivo. These findings showed that posttranslational modification of PES1 by SUMOylation may serve as a key factor that regulates the function of PES1 in vivo.

Abstract
Background: Human U three protein 14a (hUTP14a) promotes p53 degradation. Moreover, hUTP14a expression is upregulated in several types of tumors. However, the expression pattern of hUTP14a in hepatocellular carcinoma (HCC) remains unknown. The aim of this study was to investigate hUTP14a expression and its prognostic value in HCC. Methods: The hUTP14a expression was evaluated using immunohistochemistry (IHC) in HCC tissue specimens. The correlations between hUTP14a expression and clinicopathological variables were analyzed. The Kaplan-Meier method was used to analyze the association between hUTP14a expression and survival. Independent prognostic factors associated with overall survival (OS) and disease-free survival (DFS) were analyzed using the Cox proportional-hazards regression model. Results: The IHC data revealed that the hUTP14a positivity rate in HCC tissue specimens was significantly higher than that in nontumorous tissue specimens (89.9% vs. 72.7%, P < 0.05). The hUTP14a expression was detected in both the nucleolus and the cytoplasm. The positivity rate of nucleolar hUTP14a expression in HCC tissue specimens was higher than that in the nontumorous tissue specimens (29.3% vs. 10.1%, P < 0.05). No significant difference was found between HCC and nontumorous tissue specimens of cytoplasmic hUTP14a expression (60.6% vs. 62.6%, P > 0.05). In addition, no significant correlation was found between nucleolar hUTP14a expression and other clinicopathological variables. The 5-year OS and DFS rates in patients with positive nucleolar hUTP14a expression were significantly lower than those in patients with negative hUTP14a expression (P = 0.004 for OS, P = 0.003 for DFS). Multivariate analysis showed that nucleolar hUTP14a expression was an independent prognostic factor for OS (P = 0.004) and DFS (P < 0.001). Conclusions: The positivity rate of hUTP14a expression was significantly higher in HCC specimens. Positive expression of nucleolar hUTP14a might act as a novel prognostic predictor for patients with HCC.

Abstract
The nucleolar factor, digestive organ expansion factor (DEF), has a key role in ribosome biogenesis, functioning in pre-ribosomal RNA (pre-rRNA) processing as a component of the small ribosomal subunit (SSU) processome. Here we show that the peripheral sympathetic nervous system (PSNS) is very underdeveloped in def-deficient zebrafish, and that def haploinsufficiency significantly decreases disease penetrance and tumor growth rate in a MYCN-driven transgenic zebrafish model of neuroblastoma that arises in the PSNS. Consistent with these findings, DEF is highly expressed in human neuroblastoma, and its depletion in human neuroblastoma cell lines induces apoptosis. Interestingly, overexpression of MYCN in zebrafish and in human neuroblastoma cells results in the appearance of intermediate pre-rRNAs species that reflect the processing of pre-rRNAs through Pathway 2, a pathway that processes pre-rRNAs in a different temporal order than the more often used Pathway 1. Our results indicate that DEF and possibly other components of the SSU processome provide a novel site of vulnerability in neuroblastoma cells that could be exploited for targeted therapy.

Abstract
The synthesis of eukaryotic ribosomes is a complex, energetically demanding process requiring the aid of numerous non-ribosomal factors, such as the PeBoW complex. The mammalian PeBoW complex, composed of Pes1, Bop1, and WDR12, is essential for the processing of the 32S preribosomal RNA. Previous work in Saccharomyces cerevisiae has shown that release of the homologous proteins in this complex (Nop7, Erb1, and Ytm1, respectively) from preribosomal particles requires Rea1 (midasin or MDN1 in humans), a large dynein-like protein. Midasin contains a C-terminal metal ion-dependent adhesion site (MIDAS) domain that interacts with the N-terminal ubiquitin-like (UBL) domain of Ytm1/WDR12 as well as the UBL domain of Rsa4/Nle1 in a later step in the ribosome maturation pathway. Here we present the crystal structure of the UBL domain of the WDR12 homologue from S. cerevisiae at 1.7 Å resolution and demonstrate that human midasin binds to WDR12 as well as Nle1 through their respective UBL domains. Midasin contains a well conserved extension region upstream of the MIDAS domain required for binding WDR12 and Nle1, and the interaction is dependent upon metal ion coordination because removal of the metal or mutation of residues that coordinate the metal ion diminishes the interaction. Mammalian WDR12 displays prominent nucleolar localization that is dependent upon active ribosomal RNA transcription. Based upon these results, we propose that release of the PeBoW complex and subsequent release of Nle1 by midasin is a well conserved step in the ribosome maturation pathway in both yeast and mammalian cells.

Abstract
Dicer is central to small RNA silencing pathways, thus playing an important role in physiological and pathological states. Recently, a number of mutations in dicer gene have been identified in diverse types of cancer, implicating Dicer in oncogenic cooperation. Here we report on the properties of a rare splice variant of the human dicer gene, occurring in neuroblastoma cells, and not detectable in normal tissues. Due to the skipping of one exon, the alternatively spliced transcript encodes a putative truncated protein, t-Dicer, lacking the dsRNA-binding domain and bearing altered one of the two RNase III catalytic centers. The ability of the exon-depleted t-dicer transcript to be translated in vitro was first investigated by the expression of flagged t-Dicer in human cells. We found that t-dicer transcript could be translated in vitro, albeit not as efficiently as full-length dicer transcript. Then, the possible enzymatic activity of t-Dicer was analyzed by an in vitro dicing assay able to distinguish the enzymatic activity of the individual RNase III domains. We showed that t-Dicer preserved partial dicing activity. Overall, the results indicate that t-dicer transcript could produce a protein still able to bind the substrate and to cleave only one of the two pre-miRNA strands. Given the increasing number of mutations reported for dicer gene in tumours, our experimental approach could be useful to characterize the activity of these mutants, which may dictate changes in selected classes of small RNAs and/or lead to their aberrant maturation.
