Abstract
The non-POU domain-containing octamer-binding protein (NONO) is a nucleic acid-binding protein with diverse functions that has been identified as a potential cancer target in cell biology studies. Little is known about structural motifs that mediate binding to NONO apart from its ability to form homodimers, as well as heterodimers and oligomers with related homologues. We report a stapling approach to macrocyclise helical peptides derived from the insulin-like growth factor binding protein (IGFBP-3) that NONO interacts with, and also from the dimerisation domain of NONO itself. Using a range of chemistries including Pd-catalysed cross-coupling, cysteine arylation and cysteine alkylation, we successfully improved the helicity and observed modest peptide binding to the NONO dimer, although binding could not be saturated at micromolar concentrations. Unexpectedly, we observed cell permeability and preferential nuclear localisation of various dye-labelled peptides in live confocal microscopy, indicating the potential for developing peptide-based tools to study NONO in a cellular context.

Abstract
Gallbladder cancer (GBC) is a highly malignant and rapidly progressing tumor of the human biliary system, and there is an urgent need to develop new therapeutic targets and modalities. Non-POU domain-containing octamer-binding protein (NONO) is an RNA-binding protein involved in the regulation of transcription, mRNA splicing, and DNA repair. NONO expression is elevated in multiple tumors and can act as an oncogene to promote tumor progression. Here, we found that NONO was highly expressed in GBC and promoted tumor cells growth. The dysregulation of RNA splicing is a molecular feature of almost all tumor types. Accordingly, mRNA-seq and RIP-seq analysis showed that NONO promoted exon6 skipping in DLG1, forming two isomers (DLG1-FL and DLG1-S). Furthermore, lower Percent-Spliced-In (PSI) values of DLG1 were detected in tumor tissue relative to the paraneoplastic tissue, and were associated with poor patient prognosis. Moreover, DLG1-S and DLG1-FL act as tumor promoters and tumor suppressors, respectively, by regulating the YAP1/JUN pathway. N6-methyladenosine (m6A) is the most common and abundant RNA modification involved in alternative splicing processes. We identified an m6A reader, IGF2BP3, which synergizes with NONO to promote exon6 skipping in DLG1 in an m6A-dependent manner. Furthermore, IP/MS results showed that RBM14 was bound to NONO and interfered with NONO-mediated exon6 skipping of DLG1. In addition, IGF2BP3 disrupted the binding of RBM14 to NONO. Overall, our data elucidate the molecular mechanism by which NONO promotes DLG1 exon skipping, providing a basis for new therapeutic targets in GBC treatment.

Abstract
X-linked intellectual developmental disorder is a rare X-linked genetic disease, manifested as heart disease, intellectual impairment, and developmental disorders. We report a male infant who presented with dyspnea after birth. Physical examination on admission revealed poor responsiveness, deep eye sockets, a small mandible, abnormalities of the outer ears, and reduced limb muscle tone. The child was moaning with shortness of breath and a positive three-concave sign without pulmonary rales. The heart sounds were weak with a grade 2/6 diastolic heart murmur. Echocardiography showed an enlarged heart with increased trabeculae in the left ventricular muscle wall. X-linked mental retardation syndrome type 34(MRXS34, OMIM# 300967) was diagnosed after exome sequencing showed a c.1131G > A hemizygous variant in the NONO gene. After timely therapy including respiratory support, cardiac glycosides, and diuresis, the child's condition improved and he was discharged at one month of age. A literature review showed that, to date, 22 live births with X-linked mental retardation have been reported. The NONO-related phenotype can be summarized as a neurological and cardiac developmental disorder, which may be accompanied by multisystem malformations. The present case enriches the knowledge of X-linked intellectual developmental syndromes.

Abstract
Vascular calcification is a pathological process commonly associated with atherosclerosis, chronic kidney disease, and diabetes. Paraspeckle protein NONO is a multifunctional RNA/DNA binding protein involved in many nuclear biological processes but its role in vascular calcification remains unclear. Here, we observed that NONO expression was decreased in calcified arteries of mice and patients with CKD. We generated smooth muscle-specific NONO-knockout mice and established three different mouse models of vascular calcification by means of 5/6 nephrectomy, adenine diet to induce chronic kidney failure, or vitamin D injection. The knockout mice were more susceptible to the development of vascular calcification relative to control mice, as verified by an increased calcification severity and calcium deposition. Likewise, aortic rings from knockout mice showed more significant vascular calcification than those from control mice ex vivo. In vitro, NONO deficiency aggravated high phosphate-induced vascular smooth muscle cell osteogenic differentiation and apoptosis, whereas NONO overexpression had a protective effect. Mechanistically, we demonstrated that the regulation of vascular calcification by NONO was mediated by bone morphogenetic protein 2 (BMP2). NONO directly bound to the BMP2 promoter using its C-terminal region, exerting an inhibitory effect on the transcription of BMP2. Thus, our study reveals that NONO is a novel negative regulator of vascular calcification, which inhibits osteogenic differentiation of vascular smooth muscle cell and vascular calcification via negatively regulating BMP2 transcription. Hence, NONO may provide a promising target for the prevention and treatment of vascular calcification.

Abstract
BACKGROUND Ubiquitination plays an important role in proliferating and invasive characteristic of glioblastoma (GBM), similar to many other cancers. Tripartite motif 25 (TRIM25) is a member of the TRIM family of proteins, which are involved in tumorigenesis through substrate ubiquitination. METHODS Difference in TRIM25 expression levels between nonneoplastic brain tissue samples and primary glioma samples was demonstrated using publicly available glioblastoma database, immunohistochemistry, and western blotting. TRIM25 knockdown GBM cell lines (LN229 and U251) and patient derived GBM stem-like cells (GSCs) GBM#021 were used to investigate the function of TRIM25 in vivo and in vitro. Co-immunoprecipitation (Co-IP) and mass spectrometry analysis were performed to identify NONO as a protein that interacts with TRIM25. The molecular mechanisms underlying the promotion of GBM development by TRIM25 through NONO were investigated by RNA-seq and validated by qRT-PCR and western blotting. RESULTS We observed upregulation of TRIM25 in GBM, correlating with enhanced glioblastoma cell growth and invasion, both in vitro and in vivo. Subsequently, we screened a panel of proteins interacting with TRIM25; mass spectrometry and co-immunoprecipitation revealed that NONO was a potential substrate of TRIM25. TRIM25 knockdown reduced the K63-linked ubiquitination of NONO, thereby suppressing the splicing function of NONO. Dysfunctional NONO resulted in the retention of the second intron in the pre-mRNA of PRMT1, inhibiting the activation of the PRMT1/c-MYC pathway. CONCLUSIONS Our study demonstrates that TRIM25 promotes glioblastoma cell growth and invasion by regulating the PRMT1/c-MYC pathway through mediation of the splicing factor NONO. Targeting the E3 ligase activity of TRIM25 or the complex interactions between TRIM25 and NONO may prove beneficial in the treatment of GBM.

Abstract
RNA-binding proteins (RBPs) play crucial roles in the functions and homoeostasis of various tissues by regulating multiple events of RNA processing including RNA splicing, intracellular RNA transport, and mRNA translation. The Drosophila behavior and human splicing (DBHS) family proteins including PSF/SFPQ, NONO, and PSPC1 are ubiquitously expressed RBPs that contribute to the physiology of several tissues. In mammals, DBHS proteins have been reported to contribute to neurological diseases and play crucial roles in cancers, such as prostate, breast, and liver cancers, by regulating cancer-specific gene expression. Notably, in recent years, multiple small molecules targeting DBHS family proteins have been developed for application as cancer therapeutics. This review provides a recent overview of the functions of DBHS family in physiology and pathophysiology, and discusses the application of DBHS family proteins as promising diagnostic and therapeutic targets for cancers.

Abstract
This study aimed to investigate the role and mechanism of POU6F2-AS2 in the development of gastric cancer. POU6F2-AS2 expression was considerably higher in clinical stomach adenocarcinoma (STAD) tissues and gastric cancer cell lines (MKN-28 and MGC-803) than in neighbouring normal tissues and gastric mucosa epithelial cells (GES-1). POU6F2-AS2 overexpression resulted in a low overall survival probability, progression-free survival probability and post progression survival probability, as well as increased cell viability, migration and invasion of gastric cancer cells, thereby inhibiting apoptosis. Based on RNA pull-down, cycloheximide and MG132 incubation experiments, POU6F2-AS2 promoted SKP2 by stabilizing NONO expression. In addition, in vivo silencing of POU6F2-AS2 in gastric cancer cells can inhibit tumour progression and produce a synergistic antitumour effect when combined with paclitaxel. POU6F2-AS2 is overexpressed in STAD, which is attributed to a bad prognosis. In vitro and in vivo experiments have confirmed that the POU6F2-AS2/NONO/SKP2 axis promotes STAD progression, and that the silencing of POU6F2-AS2 plays a synergistic antitumour effect when combined with paclitaxel. Therefore, POU6F2-AS2 may be potentially developed as a target to inhibit STAD and reduce chemoresistance.

Abstract
Microcystic/reticular schwannoma (MRS) is a benign variant of schwannoma with a predilection for the gastrointestinal tract and skin. To date, genetic characterization of this tumor is limited. Prompted by the identification of TFE3::NONO fusion and ALK overexpression in an index case of MRS, a cohort of tumors was collected from institutional and consultation archives of two institutions. Next-generation sequencing (NGS), TFE3 fluorescence in situ hybridization (FISH), and TFE3 and ALK immunohistochemistry were performed, while clinicopathologic variables were documented. Eighteen MRS cases were identified (35 to 85 years) arising in the skin (n=8), gastrointestinal tract (n=5), adrenal gland (n=3), abdominal wall (n=1), and unknown site (n=1). Tumors showed a circumscribed to multinodular to plexiform low-power architecture with variable amounts of microcystic/reticular and solid schwannian components. Mitotic figures were scarce (0-1/10 HPFs), and atypia was absent. S100 protein and/or SOX10 immunoreactivity was noted in the microcystic/reticular and schwannian areas of all cases. NGS performed on two cutaneous tumors yielded NONO exon 12 fusion with TFE3 exon 4, and these lesions also showed HMB45 and ALK expression. Two additional cases showed ALK expression (1 weak), while a third was positive for TFE3, but these cases failed to show ALK or TFE3 rearrangement by FISH/NGS. There were no morphologic variables that correlated with the presence of NONO::TFE3. We identified a subset of microcystic/reticular schwannomas with NONO::TFE3 fusions and ALK co-expression, adding to the cohort of mesenchymal neoplasms that show ALK overexpression without rearrangement of the ALK gene.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive and fatal disease caused by a subset of cancer stem cells (CSCs). It is estimated that there are approximately 100 000 long noncoding RNAs (lncRNAs) in humans. However, the mechanisms by which lncRNAs affect tumor stemness remain poorly understood. In the present study, it is found that DIO3OS is a conserved lncRNA that is generally downregulated in multiple cancers, including HCC, and its low expression correlates with poor clinical outcomes in HCC. In in vitro cancer cell lines and an in vivo spontaneous HCC mouse model, DIO3OS markedly represses tumor development via its suppressive role in CSCs through downregulation of zinc finger E-box binding homeobox 1 (ZEB1). Interestingly, DIO3OS represses ZEB1 post-transcriptionally without affecting its mRNA levels. Subsequent experiments show that DIO3OS interacts with the NONO protein and restricts NONO-mediated nuclear export of ZEB1 mRNA. Overall, these findings demonstrate that the DIO3OS-NONO-ZEB1 axis restricts HCC development and offers a valuable candidate for CSC-targeted therapeutics for HCC.

Abstract
The NONO gene encodes a nuclear protein involved in transcriptional regulation, RNA synthesis and DNA repair. Hemizygous loss-of function, de novo or maternally inherited variants in NONO have been associated with an X-linked syndromic intellectual developmental disorder-34 (OMIM # 300967), characterized by developmental delay, intellectual disability, hypotonia, macrocephaly, elongated face, structural abnormalities of corpus callosum and/or cerebellum, congenital heart defect and left ventricular non-compaction cardiomyopathy. Few patients have been described in the literature and the phenotype data are limited. We report a 17-year-old boy with dolihocephaly, elongated face, strabismus, speech and motor delay, intellectual disability, congenital heart defect (ASD, VSD and Ebstein's anomaly), left ventricular non-compaction cardiomyopathy, bilateral inguinal hernia and cryptorchidism. Additional features included recurrent fractures due to multiple non-ossifying fibromas, thrombocytopenia, and renal anomalies. Exome sequencing revealed a de novo pathogenic variant (NM_001145408.2: c.348+2_ 348+15del) in intron 5 of the NONO gene. Renal anomalies and thrombocytopenia have been rarely reported in patients with NONO-X-linked intellectual disability syndrome, while recurrent fractures due to multiple non-ossifying fibromas have not previously been associated with this syndrome. The phenotypic spectrum of NONO-X-linked intellectual disability syndrome may be broader than currently known.

Abstract
Breast cancer is one of the most common cancers with a high mortality rate, underscoring the need to identify new therapeutic targets. Here we report that non-POU domain-containing octamer-binding (NONO) protein is overexpressed in breast cancer and validated the interaction of the WW domain of PIN1 with c-terminal threonine-proline (thr-pro) motifs of NONO. The interaction of NONO with PIN1 increases the stability of NONO by inhibiting its proteasomal degradation, and this identifies PIN1 as a positive regulator of NONO in promoting breast tumor development. Functionally, silencing of NONO inhibits the growth, survival, migration, invasion, epithelial to mesenchymal transition (EMT), and stemness of breast cancer cells in vitro. A human metastatic breast cancer cell xenograft was established in transparent zebrafish (Danio rerio) embryos to study the metastatic inability of NONO-silenced breast cancer cells in vivo. Mechanistically, NONO depletion promotes the expression of the PDL1 cell-surface protein in breast cancer cells. The identification of novel interactions of NONO with c-Jun and β-catenin proteins and activation of the Akt/MAPK/β-catenin signaling suggests that NONO is a novel regulator of Akt/MAPK/β-catenin signaling pathways. Taken together, our results indicated an essential role of NONO in the tumorigenicity of breast cancer and could be a potential target for anti-cancerous drugs. Video Abstract.

Abstract
R-loop, an RNA-DNA hybrid structure, arises as a transcriptional by-product and has been implicated in DNA damage and genomic instability when excessive R-loop is accumulated. Although previous study demonstrated that R-loop is associated with ten-eleven translocation (Tet) proteins, which oxidize 5-methylcytosine to 5-hydroxymethylcytosine (5hmC), the sixth base of DNA. However, the relationship between R-loop and DNA 5hmC modification remains unclear. In this study, we found that chronic restraint stress increased R-loop accumulation and decreased 5hmC modification in the prefrontal cortex (PFC) of the stressed mice. The increase of DNA 5hmC modification by vitamin C was accompanied with the decrease of R-loop levels; on the contrary, the decrease of DNA 5hmC modification by a small compound SC-1 increased the R-loop levels, indicating that 5hmC modification inversely regulates R-loop accumulation. Further, we showed that Tet deficiency-induced reduction of DNA 5hmC promoted R-loop accumulation. In addition, Tet proteins immunoprecipitated with Non-POU domain-containing octamer-binding (NONO) proteins. The deficiency of Tet proteins or NONO increased R-loop levels, but silencing Tet proteins and NONO did not further increase the increase accumulation, suggesting that NONO and Tet proteins formed a complex to inhibit R-loop formation. It was worth noting that NONO protein levels decreased in the PFC of stressed mice with R-loop accumulation. The administration of antidepressant fluoxetine to stressed mice increased NONO protein levels, and effectively decreased R-loop accumulation and DNA damage. In conclusion, we showed that DNA 5hmC modification negatively regulates R-loop accumulation by the NONO-Tet complex under stress. Our findings provide potential therapeutic targets for depression.

Abstract
The paraspeckle protein NONO is a multifunctional nuclear protein participating in the regulation of transcriptional regulation, mRNA splicing and DNA repair. However, whether NONO plays a role in lymphopoiesis is not known. In this study, we generated mice with global deletion of NONO and bone marrow (BM) chimeric mice in which NONO is deleted in all of mature B cells. We found that the global deletion of NONO in mice did not affect T-cell development but impaired early B-cell development in BM at pro- to pre-B-cell transition stage and B-cell maturation in the spleen. Studies of BM chimeric mice demonstrated that the impaired B-cell development in NONO-deficient mice is B-cell-intrinsic. NONO-deficient B cells displayed normal BCR-induced cell proliferation but increased BCR-induced cell apoptosis. Moreover, we found that NONO deficiency impaired BCR-induced activation of ERK, AKT, and NF-κB pathways in B cells, and altered BCR-induced gene expression profile. Thus, NONO plays a critical role in B-cell development and BCR-induced B-cell activation.

Abstract
Despite massive improvements in the treatment of B-ALL through CART-19 immunotherapy, a large number of patients suffer a relapse due to loss of the targeted epitope. Mutations in the CD19 locus and aberrant splicing events are known to account for the absence of surface antigen. However, early molecular determinants suggesting therapy resistance as well as the time point when first signs of epitope loss appear to be detectable are not enlightened so far. By deep sequencing of the CD19 locus, we identified a blast-specific 2-nucleotide deletion in intron 2 that exists in 35% of B-ALL samples at initial diagnosis. This deletion overlaps with the binding site of RNA binding proteins (RBPs) including PTBP1 and might thereby affect CD19 splicing. Moreover, we could identify a number of other RBPs that are predicted to bind to the CD19 locus being deregulated in leukemic blasts, including NONO. Their expression is highly heterogeneous across B-ALL molecular subtypes as shown by analyzing 706 B-ALL samples accessed via the St. Jude Cloud. Mechanistically, we show that downregulation of PTBP1, but not of NONO, in 697 cells reduces CD19 total protein by increasing intron 2 retention. Isoform analysis in patient samples revealed that blasts, at diagnosis, express increased amounts of CD19 intron 2 retention compared to normal B cells. Our data suggest that loss of RBP functionality by mutations altering their binding motifs or by deregulated expression might harbor the potential for the disease-associated accumulation of therapy-resistant CD19 isoforms.

Abstract
PURPOSE The NONO protein belongs to the multifunctional family of proteins that can bind DNA, RNA and proteins. It is located in the nucleus of most mammalian cells and can affect almost every step of gene regulation. Dysregulation of NONO has been found in many types of cancer; however, data regarding its expression and relevance in Multiple Myeloma (MM) are virtually absent. METHODS We took advantage of a large cohort of MM patients enrolled in the Multiple Myeloma Research Foundation CoMMpass study to elucidate better the clinical and biological relevance of NONO expression in the context of the MM genomic landscape and transcriptome. RESULTS NONO is overexpressed in pathological samples compared to normal controls. In addition, higher NONO expression levels are significant independent prognostic markers of worse clinical outcome in MM. Our results indicate that NONO deregulation may play a pathogenetic role in MM by affecting cell cycle, DNA repair mechanisms, and influencing translation by regulating ribosome biogenesis and assembly. Furthermore, our data suggest NONO involvement in the metabolic reprogramming of glucose metabolism from respiration to aerobic glycolysis, a phenomenon known as the 'Warburg Effect' that supports rapid cancer cell growth, survival, and invasion. CONCLUSION These findings strongly support the need of future investigations for the understanding of the mechanisms of deregulation and the biological role and activity of NONO in MM.

Abstract
NONO and SFPQ are involved in multiple nuclear processes (e.g., pre-mRNA splicing, DNA repair, and transcriptional regulation). These proteins, along with NEAT1, enable paraspeckle formation, thus promoting multiple myeloma cell survival. In this paper, we investigate NONO and SFPQ dimer stability, highlighting the hetero- and homodimer structural differences, and model their interactions with RNA, simulating their binding to a polyG probe mimicking NEAT1guanine-rich regions. We demonstrated in silico that NONO::SFPQ heterodimerization is a more favorable process than homodimer formation. We also show that NONO and SFPQ RRM2 subunits are primarily required for protein–protein interactions with the other DBHS protomer. Simulation of RNA binding to NONO and SFPQ, beside validating RRM1 RNP signature importance, highlighted the role of β2 and β4 strand residues for RNA specific recognition. Moreover, we demonstrated the role of the NOPS region and other protomer’s RRM2 β2/β3 loop in strengthening the interaction with RNA. Our results, having deepened RNA and DBHS dimer interactions, could contribute to the design of small molecules to modulate the activity of these proteins. RNA-mimetics, able to selectively bind to NONO and/or SFPQ RNA-recognition site, could impair paraspeckle formation, thus representing a first step towards the discovery of drugs for multiple myeloma treatment.

Abstract
About 20 years ago, large RNA-protein complexes called paraspeckles were discovered in cell nuclei. The main components of these complexes are SFPQ and NONO proteins and the long noncoding RNA NEAT1. Later, these proteins were found free in the nucleus and even in the cytoplasm. The functions of NEAT1 and paraspeckle proteins are quite diverse including retention of RNAs subjected to multiple editing of adenosine to inosine in the nucleus, response to DNA damage, transcription regulation, control of mRNA stability, regulation of splicing, and participation in the cell response to viral infection. Thus, there are numerous, albeit contradictory, data on the involvement of NEAT1, SFPQ, and NONO in the HIV-1 replicative cycle at its various stages. Here, we tried to briefly review the main cellular functions of NEAT1 RNA and SFPQ and NONO proteins. The goal of this review was also to summarize and, if possible, systematize the existing data on their role in the HIV-1 life cycle.

Abstract
Long noncoding RNAs have recently emerged as significant contributors to cancers, including breast cancer (BC). One class of long noncoding RNAs called transcribed ultraconserved regions (T-UCRs) is highly conserved in many species and closely related to diverse physiological and pathological processes. However, the function of T-UCRs in BC remains largely unclear. In this study, we identified uc.51, a T-UCR that is overexpressed in both BC tissues and cell lines and is correlated with larger tumor size. Loss- and gain-of-function assays were performed in vitro and demonstrated that uc.51 promotes the proliferation, migration, and invasion of BC cells. Mechanistically, non-POU domain-containing octamer-binding protein (NONO) was found to physically interact with uc.51 by RNA pulldown followed by mass spectrometry. This interaction was further verified by RNA immunoprecipitation. Moreover, uc.51 positively regulated the expression of NONO, maintained its stability through the ubiquitin-proteasome system, and activated the phosphorylation of CREB. Rescue experiments demonstrated that NONO overexpression compensated for the attenuated influence on BC progression resulting from downregulation of uc.51, indicating that NONO functions downstream of uc.51. In vivo functional experiments also revealed a positive correlation between uc.51 expression and tumor size. Ki-67 and NONO levels in the lv-uc.51-shRNA group were decreased compared with those in the lv-con-shRNA group, according to the immunohistochemical staining results, and a decreased incidence of distant metastasis was observed in the lv-uc.51-shRNA group in the xenograft model. Collectively, our results reveal a substantial role for the uc.51-NONO axis in BC progression and indicate that the uc.51-NONO axis has potential to be a therapeutic target for BC.

Abstract
The Hippo pathway effector TAZ promotes cellular growth, survival, and stemness through regulating gene transcription. Recent studies suggest that TAZ liquid-liquid phase separation (LLPS) compartmentalizes key cofactors to activate transcription. However, how TAZ LLPS is achieved remains unknown. Here, it is shown that the paraspeckle protein NONO is required for TAZ LLPS and activation in the nucleus. NONO is a TAZ-binding protein. Their interaction shows temporal regulation parallel to the interaction between TAZ and TEAD as well as to the expression of TAZ target genes. NONO depletion reduces nuclear TAZ LLPS, while ectopic NONO expression promotes the LLPS. Accordingly, NONO depletion reduces TAZ interactions with TEAD, Rpb1, and enhancers. In glioblastoma, expressions of NONO and TAZ are both upregulated and predict poor prognosis. Silencing NONO expression in an orthotopic glioblastoma mouse model inhibits TAZ-driven tumorigenesis. Together, this study suggests that NONO is a nuclear factor that promotes TAZ LLPS and TAZ-driven oncogenic transcriptional program.

Abstract
The androgen receptor (AR) and its related signaling pathways play an important role in the development of prostate cancer (PCa). Long non-coding RNAs (lncRNAs) are involved in the regulation of tumorigenesis and development, but their specific mechanism of action remains unclear. This study examines the function and mechanisms of action of lncRNA AC016745.3 in the development of PCa. It shows that dihydrotestosterone (DHT) results in the AR-dependent suppression of AC016745.3 expression in the LNCaP androgen-sensitive human prostate adenocarcinoma cell line. In addition, overexpression of AC016745.3 inhibits the proliferation and migration of PCa cells, and suppresses the expression of AR target genes. This research also demonstrates that the protein NONO interacts with AR and functions as an AR co-activator, promoting AR transcriptional activity. Furthermore, using RNA immunoprecipitation (RIP)-PCR experiments, the study demonstrates that both NONO and AR can bind AC016745.3. Moreover, cell phenotypic experiments reveal that NONO can promote cellular proliferation and migration, and that AC016745.3 can partially antagonize the pro-oncogenic functions of NONO in PCa cells. In summary, the results indicate that AC016745.3 can bind NONO, suppressing its ability to promote AR-dependent transcriptional activity. Furthermore, DHT-dependent suppression of AC016745.3 expression can enhance NONO's promotion effect on AR.

Abstract
Hemizygous loss-of-function variants in the non-POU domain-containing, octamer-binding gene, NONO, cause X-linked mental retardation syndrome 34 (MRXS34). Here, we describe the 12th patient in the literature with this rare syndrome, the first affected male from sub-Saharan Africa. This South African patient presented with dysmorphic features, congenital cardiac abnormalities (Ebstein's anomaly, left ventricular non-compaction, and a VSD), and developmental delay. He was enrolled in our "Undiagnosed Disease Programme." Exome sequencing identified a novel hemizygous 14bp deletion in NONO, which he inherited from his unaffected, healthy mother. His features overlap with the previous patients described, lending more support to the assertion that MRXS34 is a recognizable, albeit rare, syndrome. The cardiac anomalies are particularly distinctive, which combined with a variety of other associated features, should prompt the inclusion of NONO-associated MRXS34 in the differential diagnosis.

Abstract
BACKGROUND Increasing studies have shown a vital fact that long non-coding RNAs (lncRNAs) play a considerable regulatory role in hepatocellular carcinoma (HCC) progression. However, whether ST8 alpha-N-acetyl-neuraminide alpha-2, 8-sialyltransferase 6 antisense RNA 1 (ST8SIA6-AS1) affects the development of HCC is unclear. METHODS The target genes in HCC cell lines were quantified via utilzing quantitative real-time polymerase chain reaction (RT-qPCR) analysis and western blot. Effects of ST8SIA6-AS1 on proliferative, apoptosis and migratory ability of HCC cells were proved by a series of function experiments. The cellular distribution of ST8SIA6-AS1 was examined through fluorescent in situ hybridization (FISH) assay and subcellular fractionation experiments. RNA pulldown assay was implemented to explore the target of ST8SIA6-AS1. RNA Binding Protein Immunoprecipitation (RIP) and luciferase reporter assays were performed to identify the specific relationships between miR-338-3p and ST8SIA6-AS1/ non-POU domain containing octamer binding (NONO). RESULTS The expression of ST8SIA6-AS1 was apparently elevated in HCC cell. Silenced ST8SIA6-AS1 reduced proliferative, migratory and invasive ability of HCC cells. Moreover, ST8SIA6-AS1 targeted miR-338-3p to modulate the expression of NONO in HCC cells. CONCLUSIONS ST8SIA6-AS1 enhances the progression of HCC via miR-338-3p/NONO axis in vitro.

Abstract
Radioresistance is one of the main causes of cancer treatment failure, which leads to relapse and inferior survival outcome of cancer patients. Liquid-liquid phase separation (LLPS) of proteins is known to be involved in various biological processes, whereas its role in the regulation of radiosensitivity remains largely unknown. In this study, we characterized NONO, an RNA/DNA binding protein with LLPS capacity, as an essential regulator of tumor radioresistance. In vitro assay showed that NONO involved in DNA repair via non-homologous end joining (NHEJ) manner. NONO knockout significantly reduced DNA damage repair and sensitized tumor cells to irradiation in vitro and in vivo. NONO overexpression was correlated with an inferior survival outcome in cancer patients. Mechanically, NONO was associated with nuclear EGFR (nEGFR). Both irradiation and EGF treatment induced nEGFR accumulation, thereby increased the association between NONO and nEGFR. However, NONO was not a substrate of EGFR kinase. Furthermore, NONO promoted DNA damage-induced DNA-PK phosphorylation at T2609 by enhancing the interaction between EGFR and DNA-PK. Importantly, NONO protein formed high concentration LLPS droplets in vitro, and recruited EGFR and DNA-PK. Disruption of NONO droplets with LLPS inhibitor significantly reduced the interaction between EGFR and DNA-PK, and suppressed DNA damage-induced phosphorylation of T2609-DNA-PK. Taken together, LLPS of NONO recruits nuclear EGFR and DNA-PK and enhances their interaction, further increases DNA damage-activated pT2609-DNA-PK and promotes NHEJ-mediated DNA repair, finally leads to tumor radioresistance. NONO phase separation-mediated radioresistance may serve as a novel molecular target to sensitize tumor cell to radiotherapy.

Abstract
Ischemic stroke (IS) remains a major cause of disability and death. The changes in long non-coding RNA (lncRNA) RGD1566344 expression in the mouse cerebral cortex, including the infarct and penumbra regions after IS, are not clear. Less is known about the impact and underlying mechanisms of RGD1566344 in IS. In this study, we found that RGD1566344 levels were elevated in the ischemic infarct and penumbra regions 12 h after middle cerebral artery occlusion/reperfusion (MCAO/R) in male mice and in PC12 cells with oxygen glucose deprivation/reperfusion (OGD/R). The inhibition of RGD1566344 by small interference RNA (siRNA) significantly alleviated apoptosis in OGD/R PC12 cells. In cell transfection, quantitative real-time PCR, and Western blot experiments, we demonstrated the possible interaction of non-POU domain-containing octamer-binding protein (NONO) with RGD1566344. The NONO level in OGD/R PC12 cells was obviously increased after inhibiting the RGD1566344 treatment; subsequently the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway was activated. This demonstrated the effect of the RGD1566344-NONO-AKT axis on neural protection after IS. These results revealed a new molecular mechanism of lncRNA RGD1566344 inhibitors through targeting NONO/AKT/mTOR signaling to protect against ischemic neuronal injury, providing strong evidence for the development of promising therapeutic strategies against IS.

Abstract
Esophageal squamous cell carcinoma (ESCC) is the major subclass of esophageal cancer and one of the most life-threatening malignancies with high morbidity and mortality. Long noncoding RNAs (lncRNAs) participate in tumorigenesis and metastasis of various tumors. Here, we investigated the function of a newly identified lncRNA FAM225A in ESCC. LncRNA FAM225A expression was significantly higher in ESCC and predicted poor prognosis of ESCC patients. We confirmed that upregulation of FAM225A in ESCC and overexpression of FAM225A was associated with poor outcome in ESCC patients using TCGA ESCC cohort. Knockdown of FAM225A significantly inhibited cell growth, migration and invasion of ESCC cells in vitro and inhibited ESCC xenograft development in vivo. Mechanistically, we demonstrated that lncRNA FAM225A functioned as a competing endogenous RNA (ceRNA) via sponging miR-197-5p. LncRNA FAM225A exerted its regulatory function on ESCC proliferation and metastasis via modulating expression of miR-197-5p. MiR-197-5p overexpression antagonized the function of FAM225A, with decreased cell growth and invasion. Moreover, we identified that RNA binding protein NONO was a direct target of miR-197-5p and miR-197-5p negatively regulated NONO expression and TGF-β signaling in ESCC cells. In summary, our findings suggest that lncRNA FAM225A promotes ESCC development and progression via sponging miR-197-5p and upregulating NONO expression. These results suggest that lncRNA FAM225A could be explored as a new therapy target in ESCC treatment.

Abstract
Ubiquitin‐specific protease 11 (USP11) has been implicated in the regulation of DNA repair, apoptosis, signal transduction and cell cycle. It belongs to a USP subfamily of deubiquitinases. Although previous research has shown that USP11 overexpression is frequently found in melanoma and is correlated with a poor prognosis, the potential molecular mechanism of USP11 in melanoma remains indefinitive. Here, we report that USP11 and NONO colocalize and interact with each other in the nucleus of melanoma cells. As a result, the knockdown of USP11 decreases NONO levels. Whereas, overexpression of USP11 increases NONO levels in a dose‐dependent manner. Furthermore, we reveal that USP11 protects NONO protein from proteasome‐mediated degradation by removing poly‐ubiquitin chains conjugated onto NONO. Functionally, USP11 mediated melanoma cell proliferation via the regulation of NONO levels because ablation of USP11 inhibits the proliferation which could be rescued by ectopic expression of NONO protein. Moreover, a significant positive correlation between USP11 and NONO concentrations was found in clinical melanoma samples. Collectively, these results demonstrate that USP11 is a new deubiquitinase of NONO and that the signalling axis of USP11‐NONO is significantly involved in melanoma proliferation.

Abstract
Many long non-coding RNAs (lncRNA) are highly dysregulated in cancer and are emerging as therapeutic targets. One example is NEAT1, which consists of two overlapping lncRNA isoforms, NEAT1_1 (3.7 kb) and NEAT1_2 (23 kb), that are functionally distinct. The longer NEAT1_2 is responsible for scaffolding gene-regulatory nuclear bodies termed paraspeckles, whereas NEAT1_1 is involved in paraspeckle-independent function. The NEAT1 isoform ratio is dependent on the efficient cleavage and polyadenylation of NEAT1_1 at the expense of NEAT1_2. Here, we developed a targeted antisense oligonucleotide (ASO) approach to sterically block NEAT1_1 polyadenylation processing, achieving upregulation of NEAT1_2 and abundant paraspeckles. We have applied these ASOs to cells of the heterogeneous infant cancer, neuroblastoma, as we found higher NEAT1_1:NEAT1_2 ratio and lack of paraspeckles in high-risk neuroblastoma cells. These ASOs decrease NEAT1_1 levels, increase NEAT1_2/paraspeckles and concomitantly reduce cell viability in high-risk neuroblastoma specifically. In contrast, overexpression of NEAT1_1 has the opposite effect, increasing cell proliferation. Transcriptomic analyses of high-risk neuroblastoma cells with altered NEAT1 ratios and increased paraspeckle abundance after ASO treatment showed an upregulation of differentiation pathways, as opposed to the usual aggressive neuroblastic phenotype. Thus, we have developed potential anti-cancer ASO drugs that can transiently increase growth-inhibiting NEAT1_2 RNA at the expense of growth-promoting NEAT1_1 RNA. These ASOs, unlike others that degrade lncRNAs, provide insights into the importance of altering lncRNA polyadenylation events to suppress tumorigenesis as a strategy to combat cancer.

Abstract
Bladder cancer patients with lymph node (LN) metastasis have an extremely poor prognosis and no effective treatment. The alternative splicing of precursor (pre-)mRNA participates in the progression of various tumors. However, the precise mechanisms of splicing factors and cancer-related variants in LN metastasis of bladder cancer remain largely unknown. The present study identified a splicing factor, non-POU domain-containing octamer-binding protein (NONO), that was significantly downregulated in bladder cancer tissues and correlated with LN metastasis status, tumor stage, and prognosis. Functionally, NONO markedly inhibited bladder cancer cell migration and invasion in vitro and LN metastasis in vivo. Mechanistically, NONO regulated the exon skipping of SETMAR by binding to its motif, mainly through the RRM2 domain. NONO directly interacted with splicing factor proline/glutamine rich (SFPQ) to regulate the splicing of SETMAR, and it induced metastasis suppression of bladder cancer cells. SETMAR-L overexpression significantly reversed the metastasis of NONO-knockdown bladder cancer cells, both in vitro and in vivo. The further analysis revealed that NONO-mediated SETMAR-L can induce H3K27me3 at the promotor of metastatic oncogenes and inhibit their transcription, ultimately resulting in metastasis suppression. Therefore, the present findings uncover the molecular mechanism of lymphatic metastasis in bladder cancer, which may provide novel clinical markers and therapeutic strategies for LN-metastatic bladder cancer.

Abstract
The treatment of triple-negative breast cancer (TNBC) relies largely on chemotherapies. However, it is frequent that TNBC patients develop resistance to the chemotherapy drugs. Generation of drug-resistant cell lines facilitates the identification of drug resistance. Here, we established two paclitaxel (PTX)-resistant TNBC cancer cell lines using an intermittent and stepwise method and found that long non-coding RNA long intergenic non-protein-coding RNA p53-induced transcript (LINC-PINT) was significantly decreased in PTX-resistant cancer cells. Ectopic expression of LINC-PINT sensitized both PTX-resistant TNBC and wild-type TNBC to PTX. Moreover, RNA immunoprecipitation showed that LINC-PINT bound to RNA-binding protein NONO. Overexpression of LINC-PINT resulted in the degradation of NONO in a proteasome-dependent manner and vice versa. Knockdown of NONO with siRNA sensitized TNBC to PTX. We further analyzed the expression level of LINC-PINT and NONO in patient samples via online database and found that LINC-PINT and NONO may function antagonistically in all types of breast cancers. Taken together, our data illustrated a tumor suppressor role of LINC-PINT in sensitizing TNBC to chemotherapies via destabilizing NONO.

Abstract
Breast cancer (BC) is one of the most common cancers in women. TNBC (Triple-negative breast cancer) has limited treatment options and still lacks viable molecular targets, leading to poor outcomes. Recently, RNA-binding proteins (RBPs) have been shown to play crucial roles in human cancers, including BC, by modulating a number of oncogenic phenotypes. This suggests that RBPs represent potential molecular targets for BC therapy. Methods: We employed genomic data to identify RBPs specifically expressed in TNBC. NONO was silenced in TNBC cell lines to examine cell growth, colony formation, invasion, and migration. Gene expression profiles in NONO-silenced cells were generated and analyzed. A high-throughput screening for NONO-targeted drugs was performed using an FDA-approved library. Results: We found that the NONO RBP is highly expressed in TNBC and is associated with poor patient outcomes. NONO binds to STAT3 mRNA, increasing STAT3 mRNA levels in TNBC. Surprisingly, NONO directly interacts with STAT3 protein increasing its stability and transcriptional activity, thus contributing to its oncogenic function. Importantly, high-throughput drug screening revealed that auranofin is a potential NONO inhibitor and inhibits cell growth in TNBC. Conclusions: NONO is an RBP upstream regulator of both STAT3 RNA and protein levels and function. It represents an important and clinically relevant promoter of growth and resistance of TNBCs. NONO is also therefore a potential therapeutic target in TNBC.

Abstract
Paraspeckle protein 1 (PSPC1) overexpression in cancers is known to be the pro-metastatic switch of tumor progression associated with poor prognosis of cancer patients. However, the detail molecular mechanisms to facilitate cancer cell migration remain elusive. Here, we conducted integrated analysis of human phospho-kinase antibody array, transcriptome analysis with RNA-seq, and proteomic analysis of protein pulldown to study the molecular detail of PSPC1-potentiated phenotypical transformation, adhesion, and motility in human hepatocellular carcinoma (HCC) cells. We found that PSPC1 overexpression re-assembles and augments stress fiber formations to promote recruitment of focal adhesion contacts at the protruding edge to facilitate cell migration. PSPC1 activated focal adhesion-associated kinases especially FAK/Src signaling to enhance cell adhesion and motility toward extracellular matrix (ECM). Integrated transcriptome and gene set enrichment analysis indicated that PSPC1 modulated receptor tyrosine kinase IGF1R involved in the focal adhesion pathway and induction of diverse integrins expression. Knockdown IGF1R expression and treatment of IGF1R inhibitor suppressed PSPC1-induced cell motility. Interestingly, knockdown PSPC1-interacted paraspeckle components including NONO, FUS, and the lncRNA Neat1 abolished PSPC1-activated IGF1R expression. Together, PSPC1 overexpression induced focal adhesion formation and facilitated cell motility via activation of IGF1R signaling. PSPC1 overexpression in tumors could be a potential biomarker of target therapy with IGF1R inhibitor for improvement of HCC therapy.

Abstract
The non-POU domain-containing octamer-binding protein NONO/p54nrb , which belongs to the Drosophila behaviour/human splicing (DBHS) family, is a multifunctional nuclear protein rarely functioning alone. Emerging solid evidences showed that NONO engages in almost every step of gene regulation, including but not limited to mRNA splicing, DNA unwinding, transcriptional regulation, nuclear retention of defective RNA and DNA repair. NONO is involved in many biological processes including cell proliferation, apoptosis, migration and DNA damage repair. Dysregulation of NONO has been found in many types of cancer. In this review, we summarize the current and fast-growing knowledge about the regulation of NONO, its biological function and implications in tumorigenesis and cancer progression. Overall, significant findings about the roles of NONO have been made, which might make NONO to be a new biomarker or/and a possible therapeutic target for cancers.

Abstract
The RNA binding proteins (RBPs) have multiple roles in human cancer. However, their molecular target and function have not been clearly identified. Our genomic analysis derived from patients reveals that NONO is a potential oncogenic gene in lung cancer. NONO is highly expressed in lung cancer tissues compared with normal tissues, and its expression has been correlated with the prognosis of lung cancer patients. We found that NONO significantly influences cancer cell proliferation in lung cancer. Gene expression profiles with NONO-depleted cells revealed that the sirtuin signaling pathway is highly correlated with NONO. Thus, NONO-silenced cells caused reduction of the TCA cycle and glycolysis metabolism. We identified that NONO regulated NAMPT, which is a well-known gene involved in sirtuin signaling, and NONO has a significant correlation with NAMPT in lung cancer patients. We propose that NONO modulates energy metabolism by direct interaction with NAMPT and suggest that a functional relationship between NONO and NAMPT contributes to lung cancer cell survival. Targeting the axis can be a promising approach for patient treatment in lung cancer.

Abstract
The non-POU domain containing, octamer-binding gene, NONO, is located on chromosome Xq13.1 and encodes a member of a small family of RNA and DNA binding proteins that perform a variety of tasks involved in RNA synthesis, transcriptional regulation and DNA repair. Hemizygous loss-of-function variants in NONO have been shown to cause mental retardation, X-linked, syndromic 34 in males. Features of this disorder can include a range of neurodevelopmental phenotypes, left ventricular noncompaction (LVNC), congenital heart defects, and CNS anomalies. To date only eight cases have been described in the literature. Here we report two unrelated patients and a miscarried fetus with loss-of-function variants in NONO. Their phenotypes, and a review of previously reported cases, demonstrate that hemizygous loss-of-function variants in NONO cause a recognizable genetic syndrome. The cardinal features of this condition include developmental delay, intellectual disability, hypotonia, macrocephaly, structural abnormalities affecting the corpus callosum and/or cerebellum, LVNC, congenital heart defects, and gastrointestinal/feeding issues. This syndrome also carries an increased risk for strabismus and cryptorchidism and is associated with dysmorphic features that include an elongated face, up/down-slanted palpebral fissures, frontal bossing, and malar hypoplasia.

Abstract
The majority of breast cancers are primarily hormone‐sensitive and can be managed by endocrine therapy, although therapy‐resistant or hormone‐refractory cancers need alternative treatments. Recently, increasing attention is being paid to RNA‐binding proteins (RBP) in cancer pathophysiology. The precise role of RBP in breast cancer, however, remains to be clarified. We herein show that an RBP non‐POU domain‐containing octamer binding (NONO) plays a critical role in the pathophysiology of breast cancers regardless of their hormone dependency. Clinicopathological and immunohistochemical study of 127 breast cancer cases showed that NONO is a significant independent prognostic factor for breast cancer patients. Notably, siRNA‐mediated NONO knockdown substantially repressed the proliferation of both hormone‐sensitive MCF‐7 and hormone‐refractory MB‐MDA‐231 breast cancer cells. Integrative analysis combined with expression microarray and RIP‐sequencing (RNA immunoprecipitation‐sequencing) showed that NONO post‐transcriptionally regulates the expression of cell proliferation‐related genes by binding to their mRNAs, as exemplified by S‐phase‐associated kinase 2 and E2F transcription factor 8. Overall, these results suggest that NONO is a key regulator for breast cancer proliferation through the pre‐mRNA splicing of cell proliferation‐related genes and could be a potential new diagnostic and therapeutic target for advanced disease.

Abstract
Gallbladder carcinoma (GBC) is the most aggressive carcinoma of the biliary tract, effective chemotherapy was critical for the patients with unresectable GBC. However, chemotherapy resistance is still problematic for clinicians. Here, we identified a specific long non-coding RNA, SSTR5-AS1, in GBC patient that facilitates gemcitabine resistance. SSTR5-AS1 is significantly increased in GBC samples and cell lines, especially in gemcitabine-resistant cell lines, and higher SSTR5-AS1 expression was correlated with poorer overall survival rate in GBC patients. Our data revealed that upregulated SSTR5-AS1 facilitates gemcitabine resistance via inhibiting apoptosis. Knockdown of SSTR5-AS1 sensitized drug resistant GBC cells to gemcitabine in vitro and strongly inhibited xenografts formed by drug resistant GBC cells in vivo. Moreover, we found via streptavidin pull down assay that NONO specifically binds to sense sequence of SSTR5-AS1 and prevented proteasome mediated NONO degradation, which resulted in increased NONO protein level without affecting the transcription of NONO. NONO functions as the downstream effector of SSTR5-AS1 and is required for SSTR5-AS1 mediated gemcitabine resistance. Collectively, our data provided novel insights into lncRNA-mediated chemotherapy resistance and suggested a novel therapeutic target to improve chemotherapy strategies for unresectable GBC patients.

Abstract
Spermatogenesis and healthy testicular development are prerequisites for male reproductive function. Androgen receptor (AR), an important receptor in testicular sertoli cells, is involved in androgen specific response and its dysfunction will lead to abnormal sperm development, resulting in male infertility. NONO (non-POU-domain-containing octamer binding protein) can act as a coactivator to enhance the transcription of AR, while AR may be regulated by NONO in testicular sertoli cells. LncRNAs are involved in almost every step of spermatogenesis. However, there are few studies focus on the relationship between lncRNAs and spermatogenesis in goat testis. Therefore, in this research, high throughput sequencing and bioinformatics analysis were performed on testicular tissues of Dazu black goats at different stages of development to obtain the target NONO lncRNA. It's called lncNONO-AS. This study further explored the biological functions of lncRNA through RNA pull down, overexpression, interference, fluorescence quantification, Western blot and other techniques on the basis of in vitro culture of testis sertoli cells, and we got the following results: The gene expression levels of NONO and AR in lncNONO-AS overexpression group were significantly higher than that in the empty vector group (P < 0.01). Compared with the untreated negative control group, the expression of NONO decreased from 1.00 to 0.68 (P < 0.01), and the expression of AR decreased from 1.01 to 0.34 (P < 0.01). The results showed that lncNONO-AS could regulate the expression of AR by mediating the expression of NONO.

Abstract
Non-POU-domain-containing octamer-binding protein (NONO), a component of multifunctional Drosophila behavior/human splicing (DBHS) family, plays an important role in regulating glucose and fat metabolism, circadian cycles, cell division, collagen formation and fibrosis. Dysfunctional variants of NONO have been described as the cause of congenital heart defects in males. However, the effects of NONO deficiency on the ventricular function and cardiac fibrosis as well as the related mechanisms are not clear. In the present study, we aimed to reveal the overall phenotypes, cardiac function and fibroblasts in NONO knockout (NONO KO) mice compared with the wild-type (WT) male littermates. The results showed that the birth rate of NONOgt/0 mice was much lower than their WT male littermates at the time of weaning. The body weight of NONOgt/0 mice was 19% lower than that of WT male littermates (27.2 ± 1.49 g vs. 22.01 ± 1.20 g, P < .001). NONO KO mice exhibited continuous higher mortality from birth to a year later (P < .05). Compared with those in the WT mice, the heart weight was lower(142.0 ± 8.7 mg vs. 179.0 ± 10.4 mg, P < .001), the heart weight to body weight ratio (HW/BW) was similar, the E/A ratio was higher (1.80 ± 0.47 vs. 1.44 ± 0.26, P < .05), and the left ventricular end diastolic diameter (LVEDd) was significantly lower (2.72 ± 0.51 mm vs.3.54 ± 0.43 mm, P < .001) in the NONO KO mice. We also found excessive matrix deposition in vivo. In vitro, NONO deficiency led to fibroblasts hyperproliferation, while migration was inhibited, which would induce collagen maturation and deposition. Conversely, overexpression of NONO inhibited fibroblasts proliferation and increased migration which reduced collagen deposition. RNA-seq of cardiac fibroblasts further indicated that NONO deficiency upregulated the cell cycle regulators, which included cyclin B2, the origin recognition complex 1 (ORC1) and cell division cycle 6 (CDC6), while downregulated the migration regulators, which included myosins, integrin and coagulation factor II. Overexpression of NONO further verified the effects of these indicators. In conclusion, our study demonstrated that NONO deficiency was associated with developing heart defects in mice. Hyperproliferation of cardiac fibroblasts with dramatically excessive collagen secretion might be the cause of heart defects of NONO KO mice.

Abstract
The role of Non‐POU‐domain‐containing octamer‐binding protein (NONO) in the formation and development of angiotensin II (Ang II)‐induced abdominal aortic aneurysm (AAA) in apolipoprotein E‐knockout (ApoE−/−) mice is still unknown. In Part I, the protein level of NONO was suggestively greater in the AAA tissues compare to that in the normal abdominal aortas. In Part II, 20 ApoE−/− male mice were used to examine the transfection efficiency of lentivirus by detecting GFP fluorescence. In Part III, mice were arbitrarily separated into two groups: one was the control group without Ang II infusion, and another was the Ang II group. Mice treated with Ang II were further randomly divided into three groups to receive the same volume of physiological saline (NT group), sh‐negative control lentivirus (sh‐NC group) and si‐NONO lentivirus (sh‐NONO group). NONO silencing suggestively reduced the occurrence of AAA and abdominal aortic diameter. Compare to the NT group, NONO silencing markedly augmented the content of collagen and vascular smooth muscle cells but reduced macrophage infiltration in AAA. In addition, knockdown of NONO also increased the expression of prolyl‐4‐hydroxylase α1, whereas also decreased the levels of collagen degradation and pro‐inflammatory cytokines in AAA. We detected the interface of NONO and NF‐κB p65, and found that NONO silencing inhibited both the nuclear translocation and the phosphorylation levels of NF‐κB p65. Silencing of NONO prevented Ang II‐influenced AAA in ApoE−/− mice through increasing collagen deposition and inhibiting inflammation. The mechanism may be that silencing of NONO decreases the nuclear translocation and phosphorylation of NF‐κB.

Abstract
Splicing factor proline/glutamine-rich (SFPQ) is an essential RNA-binding protein that is implicated in many aspects of nuclear function. The structures of SFPQ and two paralogs, non-POU domain-containing octamer-binding protein and paraspeckle component 1, from the Drosophila behavior human splicing protein family have previously been characterized. The unusual arrangement of the four domains, two RNA-recognition motifs (RRMs), a conserved region termed the NonA/paraspeckle (NOPS) domain and a C-terminal coiled coil, in the intertwined dimer provides a potentially unique RNA-binding surface. However, the molecular details of how the four RRMs in the dimeric SFPQ interact with RNA remain to be characterized. Here, a new crystal structure of the dimerization domain of human SFPQ in the C-centered orthorhombic space group C2221 with one monomer in the asymmetric unit is presented. Comparison of the new crystal structure with the previously reported structure of SFPQ and analysis of the solution small-angle X-scattering data revealed subtle domain movements in the dimerization domain of SFPQ, supporting the concept of multiple conformations of SFPQ in equilibrium in solution. The domain movement of RRM1, in particular, may reflect the complexity of the RNA substrates of SFPQ. Taken together, the crystal and solution structure analyses provide a molecular basis for further investigation into the plasticity of nucleic acid binding by SFPQ in the absence of the structure in complex with its cognate RNA-binding partners.

Abstract
Although inhibition of the androgen–androgen receptor (AR) axis effectively represses the growth of prostate cancer, most of all cases eventually become castration-resistant prostate cancers (CRPCs). Enhancement of the expression of AR and its variants along with the downstream signals is important for disease progression. AR-V7, a constitutive active form of AR, is generated as a result of RNA splicing. RNA splicing creates multiple transcript variants from one pre-messenger RNA (mRNA) by removing introns/exons to allow mRNA translation. The molecular mechanisms leading to marked increases of AR and generation of AR-V7 have been unclear. However, recent papers highlighted the roles of RNA splicing factors which promote AR expression and production of variants. Notably, a broad range of splicing components were aberrantly regulated in CRPC tissues. Interestingly, expression of various spliceosome genes is enhanced by RNA-binding protein splicing factor proline- and glutamine-rich (PSF/SFPQ), leading to changes in the expression of AR transcript variants. Moreover, inhibition of several splicing factors repressed tumor growth in vivo. Altered expression of splicing factors is correlated to biochemical recurrence in prostate cancer patients. Thus, these findings suggest that splicing factors would be a potential therapeutic target. This review focuses on the emerging roles of splicing factors in prostate cancer progression and AR signaling.

Abstract
The NONO gene encodes a nuclear protein involved in RNA metabolism. Hemizygous loss-of-function NONO variants have been associated with syndromic intellectual disability and with left ventricular noncompaction (LVNC). A two-year-old boy presented to the University of Utah's Penelope Undiagnosed Disease Program with developmental delay, nonfamilial features, relative macrocephaly, and dilated cardiomyopathy with LVNC and Ebstein anomaly. Brain MRI showed a thick corpus callosum, mild Chiari I malformation, and a flattened pituitary. Exome sequencing identified a novel intronic deletion (c.154+5_154+6delGT) in the NONO gene. Splicing studies demonstrated intron 4 read-through and the use of an alternative donor causing the frameshift p.Asn52Serfs*6. Family segregation analysis showed that the variant occurred de novo in the boy's unaffected mother. MRI and endocrine findings suggest that hypopituitarism may contribute to growth failure, abnormal thyroid hormone levels, cryptorchidism, or delayed puberty in patients with NONO-associated disease. Also, including this case LVNC has been observed in five out of eight patients, and this report also confirms an association between loss of NONO and Ebstein anomaly. In some cases, unrelated individuals share the same pathogenic NONO variants but do not all have clinically significant LVNC, suggesting that additional modifiers may contribute to cardiac phenotypes.

Abstract
OBJECTIVE Breast cancer is the leading cause of cancer death among women. Nowadays, long non-coding RNAs (lncRNAs) have been identified and emerged as critical bio-markers in breast cancer tumorigenesis and progression. However, only a handful of lncRNAs which are implicated in BC have been characterized. The underlying molecular mechanisms are still largely unknown. METHODS In this study, we explored 12 nominated lncRNAs at breast cancer susceptibility loci identified by genome-wide association studies to contribute to the risk and effects of breast cancer. We then analyzed these lncRNAs in a total of 132 pairs of breast cancer tissues and surrounding non-tumor tissues from southern China population. RESULTS Here, we report a novel lncRNA, LINC01585, is aberrantly down regulated during breast cancer (BC). Next, to explore the molecular mechanisms underlying the biological activity of LINC01585, we identified LINC01585 binding protein by RNA pull-down experiments. Functionally, we found that LINC01585 overexpression inhibited breast cancer proliferation and growth by prototypical experiments. Mechanistically, LINC01585 was located in nuclear and binding with NONO protein. Interestingly, when LINC01585 was down-expressed, NONO separated from LINC01585 and then interacted with CRTC. The complex promotes CAMP/CREB target gene transcription and thus promotes the growth of breast cancer. CONCLUSIONS A series of discoveries suggest to us that LINC01585 has a potential value in anti-carcinoma therapy and deserves further investigation.

Abstract
Detection of viruses by innate immune sensors induces protective antiviral immunity. The viral DNA sensor cyclic GMP-AMP synthase (cGAS) is necessary for detection of HIV by human dendritic cells and macrophages. However, synthesis of HIV DNA during infection is not sufficient for immune activation. The capsid protein, which associates with viral DNA, has a pivotal role in enabling cGAS-mediated immune activation. We now find that NONO is an essential sensor of the HIV capsid in the nucleus. NONO protein directly binds capsid with higher affinity for weakly pathogenic HIV-2 than highly pathogenic HIV-1. Upon infection, NONO is essential for cGAS activation by HIV and cGAS association with HIV DNA in the nucleus. NONO recognizes a conserved region in HIV capsid with limited tolerance for escape mutations. Detection of nuclear viral capsid by NONO to promote DNA sensing by cGAS reveals an innate strategy to achieve distinction of viruses from self in the nucleus.

Abstract
The formation of paraspeckle, a stress-induced nuclear body, increases in response to viral infection or proinflammatory stimuli. Paraspeckle consists of lncRNA (nuclear paraspeckle assembly transcript 1, NEAT1) and protein components including NONO, SFPQ, PSPC1, etc., which are shown to be involved in viral infection and cancer. Both NEAT1 and NONO expression increase in human hepatocellular carcinoma (HCC) samples according to TCGA data. However, the role of paraspeckle in HCC progression needs further identification. IL-6 signaling is well known to contribute to HCC progression. Here we reported that IL-6 signaling increased paraspeckle formation in HCC cells. Destruction of paraspeckle formation by silencing the paraspeckle essential components NEAT1_2 or NONO could suppress IL-6-induced STAT3 phosphorylation in HCC cells, and consequently repressed IL-6-promoted in vitro HCC cell invasion, cell cycle progression and survival. Mechanistically, paraspeckle promotes IL-6-induced STAT3 phosphorylation by binding and trapping peroxiredoxin-5 (PRDX5) mRNA in nucleus, decreasing protein level of PRDX5 which can directly interact with STAT3 and inhibit STAT3 phosphorylation. Besides, glutathione S-transferase P (GSTP1) protein, which inhibits DNA damage and apoptosis through its detoxification and anti-oxidation function, was also trapped within paraspeckles under IL-6 stimulation. Paraspeckle-trapping of both PRDX5 mRNA and GSTP1 protein contributes to IL-6-increased DNA damage in HCC cells. Our results demonstrate that paraspeckle can nuclear entrap the inhibitors of IL-6/STAT3 signaling as well as DNA damage, and then strengthen the promoting effect on HCC progression by IL-6. Therefore, paraspeckle contributes to the inflammation-related HCC progression and might be a potential therapeutic target for HCC.

Abstract
UV radiations challenge genomic stability and are a recognized cancer risk factor. We previously found that the RNA-binding protein NONO regulates the intra-S phase checkpoint and its silencing impaired HeLa and melanoma cell response to UV-induced DNA damage. Here we investigated the mechanisms underlying NONO regulation upon UVC treatment. We found that UVC rays induce the expression of mir320a, which can indeed target NONO. However, despite mir320a induction, NONO mRNA and protein expression are not affected by UVC. We found through RNA immunoprecipitation that UVC rays induce the ubiquitous RNA-binding protein HUR to bind NONO 5′UTR in a site overlapping mir320a binding site. Both HUR silencing and its pharmacological inhibition induced NONO downregulation following UVC exposure, whereas concomitant mir320a silencing restored NONO stability. UVC-mediated mir320a upregulation is triggered by p53 binding to its promoter, which lies within a region marked by H3K4me3 and H3K27ac signals upon UVC treatment. Silencing mir320a sensitizes cells to DNA damage. Overall our findings reveal a new mechanism whereby HUR protects NONO from mir320-mediated degradation upon UVC exposure and identify a new component within the complex network of players underlying the DNA damage response adding mir320a to the list of p53-regulated targets upon genotoxic stress.

Abstract
Members of the Drosophila behavior human splicing (DBHS) protein family are nuclear proteins implicated in many layers of nuclear functions, including RNA biogenesis as well as DNA repair. Definitive of the DBHS protein family, the conserved DBHS domain provides a dimerization platform that is critical for the structural integrity and function of these proteins. The three human DBHS proteins, splicing factor proline- and glutamine-rich (SFPQ), paraspeckle component 1 (PSPC1), and non-POU domain-containing octamer-binding protein (NONO), form either homo- or heterodimers; however, the relative affinity and mechanistic details of preferential heterodimerization are yet to be deciphered. Here we report the crystal structure of a SFPQ/PSPC1 heterodimer to 2.3-Å resolution and analyzed the subtle structural differences between the SFPQ/PSPC1 heterodimer and the previously characterized SFPQ homodimer. Analytical ultracentrifugation to estimate the dimerization equilibrium of the SFPQ-containing dimers revealed that the SFPQ-containing dimers dissociate at low micromolar concentrations and that the heterodimers have higher affinities than the homodimer. Moreover, we observed that the apparent dissociation constant for the SFPQ/PSPC1 heterodimer was over 6-fold lower than that of the SFPQ/NONO heterodimer. We propose that these differences in dimerization affinity may represent a potential mechanism by which PSPC1 at a lower relative cellular abundance can outcompete NONO to heterodimerize with SFPQ.

Abstract
Objective The function of Epstein–Barr virus (EBV) stable intronic sequence (sis)RNAs, non-coding RNAs transcribed from a region required for EBV-mediated cellular transformation, remain unknown. To better understand the function of ebv-sisRNA-1 and ebv-sisRNA-2 from the internal repeat (IR)1 region of EBV, we used a combination of bioinformatics and biochemistry to identify associated RNA binding proteins. The findings reported here are part of ongoing studies to determine the functions of non-coding RNAs from the IR1 region of EBV. Results Human regulatory proteins HNRNPA1 (heterogeneous nuclear ribonucleoprotein A1), HNRNPC, HNRNPL, HuR (human antigen R), and protein LIN28A (lin-28 homolog A) were predicted to bind ebv-sisRNA-1 and/or ebv-sisRNA-2; FUS (fused in sarcoma) was predicted to associate with ebv-sisRNA-2. Protein interactions were validated using a combination of RNA immunoprecipitation and biotin pulldown assays. Both sisRNAs also precipitated with HNRNPD and NONO (non-POU domain-containing octamer-binding protein). Interestingly, each of these interacting proteins also precipitated non-spliced non-coding RNA sequences transcribed from the IR1 region. Our findings suggest interesting roles for sisRNAs (through their interactions with regulatory proteins) and provide further evidence for the existence of non-spliced stable non-coding RNAs.

Abstract
This study aimed to investigate the role of long noncoding RNAs (lncRNAs) in the metastasis of colorectal cancer (CRC). Metastasis is an important prognostic factor of CRC, and lncRNAs have been implicated in tumor proliferation and metastasis. The human CRC cell lines HCT116, HT29, SW480, DLD-1, and SW620 were used in the study. Genome-wide lncRNA expression patterns in metastatic lymph nodes compared with paired normal lymph nodes of CRC were assessed by microarray analysis. Gastric adenocarcinoma predictive long intergenic noncoding (GAPLINC) RNA was detected via functional prediction. The increased expression of GAPLINC was found to be positively correlated with larger tumor size, advanced tumor stage (T stage), advanced node stage (N stage), increased death, and shorter survival of patients with CRC by in situ hybridization analysis. Besides, the decreased expression of GAPLINC could significantly repress CRC cell invasion in vitro and also inhibit proliferation in vitro and in vivo. RNA pull-down with mass spectrum experiments revealed that PTB-associated splicing factor (PSF) and non-POU-domain-containing octamer-binding (NONO) protein bound to GAPLINC and reversed the effect of GAPLINC on cell invasion. Gene array and bioinformatics analyses identified that snail family zinc finger 2 (SNAI2) was involved in the biological processes of GAPLINC/PSF/NONO. This study indicated the importance of GAPLINC in promoting CRC invasion via binding to PSF/NONO and partly by stimulating the expression of SNAI2. Hence, GAPLINC may serve as a promising target for CRC diagnosis and therapy. The findings may help in developing a novel therapeutic strategy for patients with CRC.

Abstract
Developing therapeutic approaches are necessary for treating hormone-refractory prostate cancer. Activation of androgen receptor (AR) and its variants' expression along with the downstream signals are mostly important for disease progression. However, the mechanism for marked increases of AR signals and its expression is still unclear. Here, we revealed that various spliceosome genes are aberrantly induced by RNA-binding protein PSF, leading to enhancement of the splicing activities for AR expression. Our high-speed sequence analyses identified global PSF-binding transcripts. PSF was shown to stabilize and activate key long noncoding RNAs and AR-regulated gene expressions in prostate cancer cells. Interestingly, mRNAs of spliceosome-related genes are putative primary targets of PSF. Their gene expressions are up-regulated by PSF in hormone-refractory prostate cancer. Moreover, PSF coordinated these spliceosome proteins to form a complex to promote AR splicing and expression. Thus, targeting PSF and its related pathways implicates the therapeutic possibility for hormone-refractory prostate cancer.
