Identification of the transcription start site of transcribed sequences from the mouse Sry locus by CAGE-seq

ABSTRACT: The mammalian sex-determining gene Sry induces male development. Through analyzing transcriptome of pre-Sertoli cells, we identified a novel sequence transcribed within palindromic sequence surrounding Sry. To examine whether this sequence contains transcription start site, Cap analysis gene expression (CAGE) -seq analysis was performed, in which putative transcriptional start sites can be identified by sequencing the 3’ end of cDNA corresponding to 5’ end of RNA. CAGE seq revealed that Cap site was absent within the novel sequence, whereas Sry transcription start site found to locate in minus strand at chrY:2,663,800-2,663,900. Combining the result from long-read RNA seq, we concluded that this sequence is the second exon of mouse Sry.

SLIC-CAGE of paired-end sequencing data in mouse islets

Project description:Super-Low Input Carrier Cap Analysis of Gene Expression (SLIC-CAGE) to identify transcription start sites (TSS) and existing genome-wide maps of islet histone marks to characterise the contribution of transcriptional regulation of LKB1-mediated control of gene expression in mouse β-cells. SLIC-CAGE was performed as in (Cvetesic et al. - doi: 10.1101/gr.235937.118) using 100 ng of total RNA extracted as described above from islets isolated from a 18 week old female mouse on a C57BL6/J background. 12 cycles were performed for library amplification. The amplified library was purified with AMPure XP beads and visualised using a HS DNA chip (Bioanalyzer, Agilent). The library was sequenced on a HiSeq2500 instrument with paired-end, 150bp reads). SLIC-CAGE paired-end sequencing data was aligned to GENCODE assembly annotation version GRCm38.p6 using the STAR alignment tool v2.4.2a.

Global Genome Analysis of the Downstream Binding Targets of Testis Determining Factor SRY and SOX9 [SRY ChIP]

Project description:A major event in mammalian male sex determination is the induction of the testis determining factor Sry and its downstream gene Sox9. The current study provides one of the first genome wide analyses of the downstream gene binding targets for SRY and SOX9 to help elucidate the molecular control of Sertoli cell differentiation and testis development. A modified ChIP-Chip analysis using a comparative hybridization was used to identify 71 direct downstream binding targets for SRY and 109 binding targets for SOX9. Interestingly, only 5 gene targets overlapped between SRY and SOX9. In addition to the direct response element binding gene targets, a large number of atypical binding gene targets were identified for both SRY and SOX9. Bioinformatic analysis of the downstream binding targets identified gene networks and cellular pathways potentially involved in the induction of Sertoli cell differentiation and testis development. The specific DNA sequence binding site motifs for both SRY and SOX9 were identified. Observations provide insights into the molecular control of male gonadal sex determination. The current study provides one of the first genome wide analyses of the downstream gene binding targets for SRY and SOX9 to help elucidate the molecular control of Sertoli cell differentiation and testis development. At embryonic day 13 (E13) of pregnancy rats were euthanized and embryonic gonads were collected for chromatin. A modified ChIP-Chip analysis using a comparative hybridization was used to identify direct downstream binding targets for SRY and for SOX9. Then, bioinformatic analysis of the downstream binding targets was done to identify gene networks and cellular pathways that are potentially involved in the induction of Sertoli cell differentiation and testis development.

CAGE experiment of S. Cerevisiae strain CEN.PK113-7D in four different chemostat conditions

Project description:The CAGE experiment was performed in four different chemostat conditions to assess if and how much the Transcription start site landscape changes in the industrial relevant S. Cerevisiae strain CEN.PK113-7D in different conditions. CAGE was also used to obtain accurate TSS annotations for each expressed gene.

Monitoring the 5′UTR landscape reveals isoform switches to drive translational efficiencies in cancer [CAGE-seq]

Project description:Transcriptional and translational control are key determinants of gene expression, however, to what extent these two processes can be collectively coordinated is still poorly understood. Here, we use Nanopore long-read sequencing and cap analysis of gene expression (CAGE-seq) to document the landscape of 5′ and 3′ untranslated region (UTR) isoforms and transcription start sites of epidermal stem cells, wild-type keratinocytes and squamous cell carcinomas. Focusing on squamous cell carcinomas, we show that a small cohort of genes with alternative 5′UTR isoforms exhibit overall increased translational efficiencies and are enriched in ribosomal proteins and splicing factors. By combining polysome fractionations and CAGE-seq, we further characterize two of these UTR isoform genes with identical coding sequences and demonstrate that the underlying transcription start site heterogeneity frequently results in 5′ terminal oligopyrimidine (TOP) and pyrimidine-rich translational element (PRTE) motif switches to drive mTORC1-dependent translation of the mRNA. Genome-wide, we show that highly translated squamous cell carcinoma transcripts switch towards increased use of 5′TOP and PRTE motifs, have generally shorter 5′UTRs and expose decreased RNA secondary structures. Notably, we found that the two 5′TOP motif-containing, but not the TOP-less, RPL21 transcript isoforms strongly correlated with overall survival in human head and neck squamous cell carcinoma patients. Our findings warrant isoform-specific analyses in human cancer datasets and suggest that switching between 5′UTR isoforms is an elegant and simple way to alter protein synthesis rates, set their sensitivity to the mTORC1-dependent nutrient-sensing pathway and direct the translational potential of an mRNA by the precise 5′UTR sequence.

Transcriptome of hepatocellular carcinoma using CAGE

Project description:An increasing number of non-coding RNAs (ncRNAs) are implicated in various human diseases including cancer; however ncRNA transcriptome of hepatocellular carcinoma (HCC) remains largely unexplored. We use CAGE (Cap Analysis of Gene Expression) to comprehensively map transcription start sites (TSSs) across different etiologies of human HCC as well as mouse HCC, with particular emphasis on ncRNAs distant from protein-coding genes. We find thousands of significantly up-regulated distal ncRNAs in HCC tumors compared to their matched non-tumors, which are as many as protein-coding genes. Moreover, we identify many LTR retroviral promoters activated in HCC tissues and expressed in a subfamily-specific manner, which account for approximately 20% of the up-regulated distal ncRNAs. The transcripts derived from LTRs, determined by 3' RACE, are multi-exon nuclear ncRNAs typically 0.5-2kb in length. This study sheds light on ncRNA transcriptome of human and mouse HCC. Expression profiles using CAGE for 37 mouse HCC. The human data are archived at dbGaP (phs000885.v1.p1). An umbrella BioProject has been created to associate the GEO and dbGaP BioProjects: PRJNA278792
