Prof. Dr. Özcan Demirel kişisel web sayfasıdır. We validated selected aberrant splicing events identified in SFmut MDS using RT-PCR (supplemental Figure 11A-J). He graduated from Ankara - Gazi Teacher Training College, the Department of English Language Teaching in 1964 and was awarded his PhD degree in Curriculum and Instruction in 1979. As these 2 ZRSR2 mutant cases also harbored a SRSF2 mutation, we compared them with SRSF2 mutant cases (without ZRSR2 mutations) and with healthy control individuals to identify the aberrant splicing events that can be attributed to the presence of the ZRSR2 mutations. Within each heat map, dysregulated pathways, transcriptional regulators and drug/chemical names are ranked by the IPA ranking score. Given the known function of SF3B1, we examined the aberrant A3SS events associated with SF3B1 mutation and found a more pronounced reduction of gene expression levels for NMD-sensitive events (median log2 fold −0.2 compared with median log2 fold −0.03 for NMD-insensitive events), although this did not reach statistical significance (supplemental Figure 2D). Medscape, LLC is jointly accredited by the Accreditation Council for Continuing Medical Education (ACCME), the Accreditation Council for Pharmacy Education (ACPE), and the American Nurses Credentialing Center (ANCC), to provide continuing education for the healthcare team. The major cellular processes and dysregulated pathways were identified in the CD34+ cells and in precursors of MDS-affected lineages of SFmut patients with MDS. We found increased inclusion of a “poison” cassette exon of EZH2 in SRSF2mut cases, as previously reported,24 and observed the same aberrant splicing event in U2AF1mut cases. demirel.ozcan@gmail.com. Results shown in A-G were obtained from 5 independent experiments, except for C (3 replicates). In contrast, among the highest-ranking aberrant splicing events in SRSF2mut (supplemental Table 4) and U2AF1mut MDS (supplemental Table 4), the largest proportion was SE (n = 31/40 and n = 27/40, respectively). Pathway analysis and upstream regulator analysis was performed on the genes showing significant aberrant splicing events (FDR <0.05) using Ingenuity Pathway Analysis (IPA) software (Qiagen).

ZRSR2 is another recurrently mutated splicing factor gene in MDS.7,8 We performed RNA-seq on CD34+ cells from 2 MDS cases with ZRSR2 mutations to determine the aberrant splicing events in these samples. The publication costs of this article were defrayed in part by page charge payment. Ulusal Eğitim Bilimleri Kongresine davet etmekten büyük bir mutluluk duyuyoruz. We investigated the correlations between aberrantly spliced events and clinical variables. The aberrant splicing events associated with each mutated splicing factor mainly affected different genes, although some overlap was observed (Figure 1J). The analysis of a large dataset allowed us for the first time to compare and contrast the effects of different mutated splicing factor genes in MDS CD34+ cells. Aberrant splicing of genes involved in heme metabolism and iron processing in SFmut MDS (XLSX, 48 KB), Document 8. A total of 147, 132, and 181 genes were aberrantly spliced distinctly in association with SF3B1mut, SRSF2mut, and U2AF1mut MDS cases, respectively (supplemental Data 3). We identified several aberrant splicing events associated with clinical features for SF3B1mut MDS, demonstrating that specific splicing events may contribute directly to aspects of the disease phenotype. The large majority of aberrantly spliced genes associated with each mutated splicing factor were different, although some overlap was observed. Focal adhesion and extracellular exosomes play a role in cancer and leukemia,95,96 and our data implicate their dysregulation as drivers of poor survival in both MDS and AML. (E and L) Percentage of CD36+CD235a+ cells in erythroid cultures with knockdown of AKAP8 (E) and SEPT2 (L) on day 11. Data represent the mean ± SEM. These aberrantly spliced genes include SEPT2 and DYNLL1 in SF3B1mut cases, PKFM and METTL17 in SRSF2mut cases, and HMGXB4 and LAT2 in U2AF1mut cases.

AKAP8 and SEPT2 play important roles in the regulation of mitosis and cell growth.70,71 Cell growth is dysregulated in MDS,1-4 and thus we selected AKAP8 and SEPT2 for functional studies. The REVIGO treemap of 118 GO terms associated only with SF3B1mut MDS showed multiple GO terms associated with cellular response to DNA damage stimulus and cell cycle processes (supplemental Figure 3B). Hierarchical clustering performed using the aberrant splicing events identified for each mutated splicing factor showed that SF3B1mut cases clustered together and separately from SFwt cases and healthy control individuals (Figure 1G). HSCs expressing splicing factor mutations show a compromised repopulation capacity in mice compared with wild-type HSCs, however,24-28 and precisely how splicing factor mutations confer a positive selection advantage in the BM remains a mystery. DOM3Z showed reduced intron retention using an upstream A3SS, although in this case there was no observed switching in A3SS use (supplemental Figure 6C). Functional effects of AKAP8 and SEPT2 knockdown on erythroid differentiation. We identified aberrantly spliced events associated with clinical variables, and isoforms that independently predict survival in MDS and implicate dysregulation of focal adhesion and extracellular exosomes as drivers of poor survival. These results suggest that aberrant splicing of SEPT2 or AKAP8 may lead to impaired erythropoiesis in association with SF3B1 and SRSF2 mutations in MDS. 1974 yılında SF3B1mut, SRSF2mut, or U2AF1mut patients were compared both with healthy control individuals and with SFwt patients, identifying more than 200 misregulated splicing events for each mutated splicing factor (Figure 1A-C; supplemental Data 2). A marked convergence of significant GO themes was identified, with 74 GOs common to all SFmut MDS groups (Figure 2A; supplemental Data 5). We analyzed various properties of the major misregulated splicing events. All P-values were obtained by 1-way ANOVA with Bonferroni’s posttest with the exception of G and N, in which 2-way ANOVA with Bonferroni’s posttest was used. It supports drag-and-drop, effects, transitions, 3D video editing, text and caption overlay, video stabilization, easy … Her hakkı saklıdır. Functional studies demonstrated that knockdown of the mitosis regulators SEPT2 and AKAP8, aberrantly spliced target genes of SF3B1 and SRSF2 mutations, respectively, led to impaired erythroid cell growth and differentiation.

This study illuminates the effect of the common spliceosome mutations on the MDS phenotype and provides novel insights into disease pathophysiology. Conflict-of-interest disclosure: The authors declare no competing financial interests. The effect of splicing factor mutations remains largely unexplored in the different lineages affected in MDS,43 and we showed aberrant splicing of important genes for erythroid, granulocyte, and monocyte function in the respective cell population in SFmut MDS. 1992-1997 yılları arasında YÖK Dünya Bankası öğretmen yetiştirme Projesinde yönetim kurulu üyesi; 1996-1997 yılları arasında Milli Eğitim Bakanlığı Dünya Bankası projesinde program geliştirme uzmanı, 2000-2002 yılları arasında MEDA Temel Eğitime Destek projesinde proje eşbaşkanı olarak çalışmıştır. Sirtuins are histone deacetylases, some of which reside in the mitochondria,81 with diverse roles in regulating metabolism, inflammation, genome stability, and cell proliferation, and have been implicated in aging, cancer and survival.82,83. Several genes involved in the suppression/regulation of R-loop formation were aberrantly spliced in SFmut MDS in our study, including SETX and ATR.87-89 SETX resolves R-loops89 and its loss leads to aberrant R-loop accumulation.87 Aberrant splicing of R-loop-related genes may contribute to increased formation of R-loops in SFmut MDS. Gazi Eğitim Enstitüsü İngilizce bölümünü bitirmiş ve on yıl A similar approach identified drugs/chemicals that can affect the expression of the genes found to be aberrantly spliced in SFmut MDS. The data discussed in this article have been deposited in the NCBI’s Gene Expression Omnibus (GEO) repository (GEO accession number: GSE114922). acknowledges funding from Associazione Italiana per la Ricerca sul Cancro (AIRC, Investigator Grant 20125). Özcan DEMİREL, 26.5.1943 yılında Adapazarı- For each category, the number of significant aberrant splicing events was normalized to the total number of events identified by the rMATS pipeline. Değerli Eğitim Bilimciler, Okul Yöneticileri, Öğretmenler ve Eğitim Fakültelerinin Lisans ve Lisansüstü Öğrencileri; okulundan mezun olmuş ve bir öğretim yılı Anadolu'nun Results shown in H-N were obtained from 4 independent experiments. Aberrant splicing of 5 genes was observed in SF3B1mut, SRSF2mut, and U2AF1mut MDS, and thus represent common targets. Among the significant pathways uniquely dysregulated in one SFmut MDS group, the regulation of eIF4 and p70S6K signaling pathway (a key pathway for translational regulation) was dysregulated in SF3B1mut MDS (Figure 2B; supplemental Table 5), whereas hypoxia signaling was dysregulated in SRSF2mut MDS (Figure 2B; supplemental Table 6). The rMATS bioinformatics pipeline34,42,43 was used to detect alternative (including cryptic) splicing events and categorize them as alternative 3′ splice site (A3SS) usage, alternative 5′ splice site (A5SS) usage, exon skipping (SE), mutually exclusive exons (MXE), or retained introns (RI). Supplemental methods, tables, and figures (PDF, 5 MB), Document 2.RNA-seq quality control metrics (XLSX, 22 KB), Document 3. Dysregulation of splicing factors leads to R-loop formation with associated genomic instability, resulting in activation of the DDR.50-52 Elevated R-loops have been shown in Srsf2(P95H) mice,51 and SRSF2 is involved in maintaining genomic stability.51,52 Thus, R-loop formation and activation of the DDR are tightly linked cellular processes, and interestingly, regulators of these processes show aberrant splicing in our study. To date, very few of the aberrantly spliced isoforms identified in SFmut malignancies have been functionally characterized.6 We identified aberrant splicing of the mitosis regulators SEPT299,100 and AKAP8,71 leading to their downregulation in the CD34+ cells of SF3B1mut and SRSF2mut MDS, respectively. Several commonly dysregulated pathways were associated with all 3 mutated splicing factors, some of which are relevant to the known MDS pathophysiology, including mitochondrial dysfunction, oxidative phosphorylation, and heme biosynthesis, linking aberrant splicing with impaired mitochondrial function in MDS. (B,I) Growth curves for erythroid cells with knockdown of AKAP8 (B) and SEPT2 (I). Sapanca'da doğmuş, 1960'da Arifiye İlköğretmen For example, ERCC3 showed reduced retention of intron 10 in conjunction with use of an A3SS 18 nt upstream of the canonical 3SS, with the change in intron retention exceeding the change in A3SS use (supplemental Figure 6B). An aberrant splicing event (RI) in the caspase 1 (CASP1) gene, the key effector of pyroptosis,46 was observed in SF3B1mut MDS cases in our study. These data are in agreement with other studies.24,35 For events associated with SF3B1 mutations, gene expression levels were overall lower for NMD-sensitive events (supplemental Figure 2C). To identify aberrantly spliced transcripts associated with SF3B1, SRSF2, and U2AF1 mutations in MDS hematopoietic stem and progenitor cells, we performed RNA-seq on CD34+ cells from 82 patients with MDS and 8 healthy control individuals. GO analysis on aberrantly spliced genes in SFmut MDS (XLSX, 42 KB), Document 6. We refined these overlapping GOs using REVIGO, which removes redundant GO terms and visualizes the most informative ontology themes. In all cases, the isoforms that predicted survival were ones that would be generated because of the aberrant splicing event identified. Using rMATS, a total of 137 misregulated splicing events were identified, including 11 A3SS, 6 A5SS, 51 RI, 63 SE, and 6 MXE events (supplemental Figure 8A; supplemental Data 7). Among the top 40 aberrant splicing events in SF3B1mut MDS (supplemental Table 4), the largest proportion was A3SS (n = 21/40), followed by RI (n = 11/40). He graduated from Ankara - Gazi Teacher Training College, the Department of English Language Teaching in 1964 and was awarded his PhD degree in Curriculum and Instruction in 1979. (C-H) Ranked heat maps showing the top 15 dysregulated pathways (C,F), top 15 transcriptional regulators (D,G), and top 6 drug/chemical gene sets (E,H) in MON, GRA, and ERY populations of SF3B1 mutant and SRSF2 mutant patients with MDS.

Of these, the AKAP8 SE and SEPT2 A3SS events identified generate premature termination codons predicted to trigger NMD and were associated with significant downregulation in SRSF2mut and SF3B1mut MDS, respectively (supplemental Figure 11B,F). After staining with CD34-APC (8G12), CD45-FITC (2D1), and CD14-PE (MφP9) (all from BD Biosciences, San Jose, CA), monocytes/macrophages restricted precursors (CD34−CD45+SSCmedCD14+), granulocytic precursors (CD34−CD45medSSChigh), and erythroid precursors (CD34−CD45−) were isolated by FACS using a FACSAria cell sorter and the FACSDIVA software (BD Biosciences). Loss of XPB activity contributes to R-loop-mediated DNA damage.62 Use of the upstream A3SS in the upregulated intron would insert 6 amino acids between the helicase and ResIII domains and may affect protein function. (A-B) UpSet plots showing the overlap of aberrant splicing events identified in monocyte (MON), granulocyte (GRA), and erythroid (ERY) precursor cell populations isolated from SF3B1 (A) and SRSF2 (B) mutant MDS patient samples.

Distinct and common aberrantly spliced genes and differential gene expression in SFmut MDS as shown in Figure 1J (XLSX, 77 KB), Document 5. These include RI events of AP1G2, DOM3Z, and ERCC3 with ANC, and a RI event of NICN1 with Plt, indicating increased aberrant splicing of these genes in MDS cases with higher ANC and higher platelets, respectively. Two retinoid drugs (CD437 and ST1926), the nucleotide antagonist 5-fluorouracil, and the mTOR inhibitor sirolimus (rapamycin) were significant for all 3 mutated splicing factors (Figure 2D), indicating that a significant proportion of the target genes of these compounds are aberrantly spliced in SFmut MDS. Tightly controlled protein synthesis is critical for HSC (and progenitor) function and serves as a tumor suppressive mechanism,77 implicating the aberrant splicing of multiple translation-related genes in SFmut MDS in disease pathogenesis. We have performed a comprehensive and systematic analysis to determine the effect of these commonly mutated splicing factors on pre-mRNA splicing in the bone marrow stem/progenitor cells and in the erythroid and myeloid precursors in splicing factor mutant MDS. CD34+ cells from healthy donors (Lonza) were cultured in erythroid differentiation media for 14 days, as described previously.45 SEPT2 and AKAP8 genes were knocked down individually, using Mission shRNA lentiviral vectors (Sigma-Aldrich). Site içerisinde yer alan bilgiler kaynak gösterilerek kullanılabilir. Mutations in splicing factor genes define distinct clinical phenotypes in MDS.6,14 We investigated the overlap of the aberrantly spliced genes identified in SF3B1mut, SRSF2mut, and U2AF1mut patients. okulundan mezun olmuş ve bir öğretim yılı Anadolu'nun Aberrantly spliced isoforms predict MDS survival and implicate dysregulation of focal adhesion and exosomes as drivers of poor survival. süreyle orta dereceli okullarda İngilizce öğretmenliği ve Öğretim Teknolojileri ve Materyal Geliştirme (2001), Öğretmenlik Mesleğine Giriş (2001), Öğretim İlke ve Yöntemleri (1999), Developing Test Techniques (1998), Developing Reading Skills (1998), Eğitim Terimleri (1987) , Proficiency in English (1986-1993), Tests for Proficiency in English (1985-1993), English for Hotels and Tourism, Book I (1984) ve English-Turkish Dictionary (1981) ortak yazarlı yayınlarıdır.

Özcan DEMİREL, 26.5.1943 yılında Adapazarı- Sapanca'da doğmuş, 1960'da Arifiye İlköğretmen okulundan mezun olmuş ve bir öğretim yılı Anadolu'nun bir köyünde ilkokul öğretmenliği yapmıştır. SF3B1, SRSF2, and other splicing factors are components of a DNA damage-induced mRNA splicing complex,84 linking splicing factors to the DDR. The reads were mapped to human genome GRCh37 using HISAT2 version 2.0.0-beta.39 Uniquely mapped read pairs were counted using featureCounts,40 included with subread v1.5.0.41 Quality control was performed on the mapped files using Picard CollectRnaSeqMetrics (http://broadinstitute.github.io/picard; supplemental Data 1). SF3B1mut-misregulated A3SSs showed varying sequence profiles between canonical and cryptic sites (supplemental Figure 5A) and the characteristic 16 nt peak separation of upstream cryptic sites from their associated canonical sites (supplemental Figure 5B).34,64-66 Exons downregulated in association with U2AF1 mutations in the ZF1 and ZF2 domains (S34 and R156/Q157, respectively) showed altered 3′ splice site (3SS) logos (supplemental Figure 5C) consistent with contact by ZF1 and ZF2 at the −3 and +1 positions.35 SRSF2mut-misregulated exons showed no alterations in splice site compositions (supplemental Figure 5D), but consistent with previous observations,24 CCNG motifs were enriched in upregulated cassette exons and GGNG motifs in downregulated exons (supplemental Figure 5E). bir köyünde ilkokul öğretmenliği yapmıştır. Erythroid cells with AKAP8 or SEPT2 knockdown showed significantly impaired growth and G1/S transition arrest compared with the scramble control (Figure 5A-C,H-J). RNA-seq analysis of CD34+ cells identifies novel aberrantly spliced genes and dysregulated pathways in splicing factor mutant MDS. We have performed a comprehensive and systematic analysis to determine the effect of these commonly mutated splicing factors on pre-mRNA splicing in the bone marrow stem/progenitor cells and in the erythroid and myeloid precursors in splicing factor mutant MDS. Aberrantly spliced genes and dysregulated pathways were identified in the MDS-affected lineages in splicing factor mutant MDS. Aberrant RNA splicing occurs as a consequence of splicing factor gene mutations in several human malignancies.29-33 Some studies have investigated aberrant splicing in MDS and AML patients with splicing factor mutations,24,28,34-38 but included small numbers of splicing factor mutant (SFmut) cases and/or analyzed unfractionated BM or mononuclear cell samples. The processes and pathways by which splicing factor mutations exert their effects are not established in the stem/progenitor cells and erythroid and myeloid precursors in MDS. Of 200 and 150 genes involved in heme metabolism or in iron homeostasis and transport (supplemental Methods), respectively, we found several showing aberrant splicing events in SF3B1mut, SRSF2mut, and U2AF1mut MDS cases, with a higher number of events occurring in SF3B1mut MDS cases (supplemental Data 6).

Gazi Eğitim Enstitüsü İngilizce bölümünü bitirmiş ve on yıl Aberrant splicing events associated with each mutated splicing factor were identified on the basis of the overlap between the lists of significant events identified by rMATS consistently in the comparisons of SFmut MDS both with SFwt MDS and with healthy control individuals (false discovery rate [FDR], <0.05 and inclusion level difference of >0.1 or <−0.1). Several biological processes were significantly affected in all 3 SFmut MDS groups, including RNA splicing, RNA processing, mRNA translation, and mitochondrial translation. The research was approved by the relevant institutional review boards or ethics committees, and all participants gave written informed consent. Clinical variables showing a significant difference between SFmut and SFwt patients with MDS were lower percentage of BM blasts and higher number of white blood cells, ANC, and Plt in the SF3B1mut group (supplemental Table 9). Özcan DEMİREL, 01 Mart 1943 yılında Adapazarı-Sapanca’da doğmuş, 1960’da Arifiye İlköğretmen okulunu, 1964 yılında Gazi Eğitim Enstitüsü İngilizce bölümünü bitirmiştir. müdür yardımcılığı görevi yapmıştır. Most U2AF1 mutations affect the S34 and R156/Q157 codons within the 2 zinc finger (ZF) domains.9 All U2AF1mut cases clustered together, with the S34 mutants and the R156/Q157 mutants in 2 subclusters (Figure 1I). You can add, exclude, or delete schedule policy entity associations. Genes with isoforms that significantly predicted survival in MDS in multivariate models. After sorting, morphology and purity of the isolated cell populations were determined and the purity was higher than 95%. Lentiviruses were produced and used to transduce CD34+ cells from healthy donors, as described previously.43. Hacettepe Üniversitesi'ne İngilizce öğretim görevlisi olarak Here, the mutational profile of the patients with MDS was determined using a next-generation sequencing-based myeloid gene panel20 (supplemental Table 3; supplemental Figure 1B). Significantly dysregulated gene expression was observed for 33 (16%) of the aberrantly spliced genes identified in SF3B1mut MDS cases, with a lower percentage observed for SRSF2mut-associated and U2AF1mut-associated aberrantly spliced genes (supplemental Data 3).
