Project description:GSM1056261-GSM1056272: NFX1-123 has been shown to associate with a number of RNA processing proteins, such as cytoplasmic poly(A) binding proteins (PABPC), to affect mRNA stability and translational efficiency of target genes. The high-risk human papillomavirus type 16E6 (HPV 16E6) induces telomerase activity by activation of hTERT, the catalytic subunit of telomerase. NFX1-123 can bind to hTERT mRNA and increase its stability in HPV 16E6 expressing keratinocytes (16E6 NHKs). Little is known regarding what other transcripts, and downstream signaling pathways, may be dependent on NFX1-123. In order to determine additional cellular transcripts affected by HPV 16E6 and NFX1-123, we assessed global gene expression changes in cells in which NFX1-123 was overexpressed or knocked down by short hairpin RNAs (shRNA) when compared to an isogenic scramble control, in three independently derived 16E6 NHKs GSM1212499-GSM1212510: NFX1-123 has been shown to associate with a number of RNA processing proteins, such as cytoplasmic poly(A) binding proteins (PABPC), to affect mRNA stability and translational efficiency of target genes.

GSM1056261-GSM1056272: Three independent 16E6 expressing NHK cell lines were expanded and transduced with: short hairpin RNA (sh1) that knocked down NFX1-123 by 20%, short hairpin RNA (sh3) that knocked down NFX1-123 by 80%; a non-targeting isogenic shRNA scramble control; or a NFX1-123 overexpression construct with a FLAG-tag (FNFX1-123WT) that increased its RNA expression on average 3.5-fold. In total, twelve samples were used for the microarray, derived from the three initial NHK cell lines.

Project description:NFX1-91, a novel E6 cellular downstream target, functions as a transcriptional regulator and is involved in repressing hTERT expression. Other functions and downstream targets regulated by NFX1-91 were not well understood. We used microarrays to determine gene expression deregulated when NFX1-91 was knocked down. HCT116 cells was infected with lentivirus carrying NFX1-91 shRNA or control β-Galactosidase shRNA to stably knock down target gene expression. Total RNAs were extracted and hybridized on Affymetrix microarrays.

Project description:The investigation of spliceosomal processes is currently a topic of intense research in molecular biology. In the molecular mechanism of alternative splicing, a multi-protein–RNA complex – the spliceosome – plays a crucial role. To understand the biological processes of alternative splicing, it is essential to comprehend the biogenesis of the spliceosome.
In this paper, we propose the first abstract model of the regulatory assembly pathway of the human spliceosomal subunit U1. Using Petri nets, we describe its highly ordered assembly that takes place in a stepwise manner.

Project description:Complex functional coupling exists between transcriptional elongation and pre-mRNA alternative splicing. Pausing sites and changes in the rate of transcription by RNAPII may therefore have a fundamental impact in the regulation of alternative splicing. Here, we show that the elongation and splicing-related factor TCERG1 regulates alternative splicing of the apoptosis gene Bcl-x in a promoter-dependent manner. TCERG1 promotes the splicing of the short isoform of Bcl-x (Bcl-xs) through the SB1 regulatory element located in the first half of exon 2. Consistent with these results, we show evidence for in vitro and in vivo interaction of TCERG1 with the Bcl-x pre-mRNA. Transcription profile analysis reveals that the RNA sequences required for the effect of TCERG1 on Bcl-x alternative splicing coincide with a putative polymerase pause site. Furthermore, TCERG1 modifies the impact of a slow polymerase on Bcl-x alternative splicing. In support of a role for an elongation mechanism in the transcriptional control of Bcl-x alternative splicing, we found that TCERG1 modifies the amount of pre-mRNAs generated at distal regions of the endogenous Bcl-x. Most importantly, TCERG1 affects the rate of RNAPII transcription of endogenous human Bcl-x. We propose that TCERG1 modulates the elongation rate of RNAPII to relieve pausing, thereby activating the pro-apoptotic Bcl-xS 5’ splice site. ChIP-Seq

Project description:Background: We investigated the effect of PPIA overexpression on downstream gene expression at the cellular level. Methods: The PPIA gene was overexpressed in human umbilical vein endothelial cells. Then, transcriptome sequencing was performed. The differentially expressed genes and genes with alternative splicing were screened. GO and KEGG analyses were performed. Nine differentially expressed genes and 7 genes with alternative splicing were validated by real-time quantitative PCR. Results: After PPIA overexpression, 328 genes were differentially expressed, including 157 up-regulated genes and 171 down-regulated genes. GO enrichment analysis of up-regulated genes found that the enriched GO terms included extracellular region, protein binding and metal ion binding, etc. For down-regulated genes, the enriched GO terms included neuron projection, protein binding, endoplasmic reticulum unfolded protein response, etc. KEGG showed that the up-regulated genes were mainly enriched in gastric acid secretion, AMPK signaling pathway, etc; and, the down-regulated genes were enriched in transcriptional misregulation in cancer, TNF signaling pathway, etc. Real-time quantitative PCR analysis of ATF4 (activating transcription factor 4), PPP1R15A (protein phosphatase 1, regulatory (inhibitor) subunit 15A protein phosphate 1, regulatory (inhibitor) subunit 15A), GADD45B (growth arrest and DNA damage inducible protein 45B), SGK1 (serum/glucocorticoid regulated kinase 1), DDIT3 (Recombinant DNA Damage Inducible Transcript 3), PMAIP1 (Phorbol-12-myristate-13-acetate-induced Protein 1), SULF1 (Sulfatase 1), GDF6 (Growth Differentiation Factor 6), and XBP1 (X-Box Binding Protein 1) obtained consistent results with the sequencing results. On the other hand, multiple genes with alternative splicing were identified and analyzed with KEGG and GO. Real-time quantitative PCR validation showed that the probability of alternative splicing in LHPP, APH1A, BRD1, and ORAI3 was increased. However, the changes of NFX1, SERGEF, and PCBP4 were inconsistent with the sequencing results. Conclusion: The overexpression of PPIA in human umbilical vein endothelial cells causes changes in the expression of downstream genes, and induces alternative splicing in multiple genes. PPIA may be involved in the development of atherosclerosis by regulating the expression of downstream genes and causing endothelial cell dysfunction.
