XH lncRNA tend to participate in transcriptional or development regulations as their coding neighbors

ABSTRACT: We report that head to head long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and classified to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we knockdown serveral XH lncRNA by shRNA in embryonic stem cells and induce nondirectional differentiation by removing LIF or neural differentiation by RA. Knockdown of XH lncRNAs led to uniform downregulation of nearby coding genes, and form regulatory circuits with its nearby coding genes to fine-tune embryonic lineage development. We propose that XH lncRNA may function primarily as 'cis-regulators' of the expression of nearby protein-coding genes, and tend to participate in transcriptional or development regulations as their coding neighbors.

Evx1as and EVX1 knockouts by CRISPR

Project description:We report that long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and tend to located closely to protein-coding genes. To study position relationship between lncRNA and protein-coding genes, we classified all of lncRNA to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we knockdown serveral XH lncRNA by shRNA in embryonic stem cells and induce nondirectional differnetiation by removing LIF or neural differnetiation by RA. Knockdown of XH lncRNAs led to uniform downregulation of nearby coding genes, and form regulatory circuits with its nearby coding genes to fine-tune embryonic lineage development. In addition, we also knockout one lncRNA-Evx1as and its nearby protein-coding gene-EVX1 by CRISPR, and get similar results as knockdown.We propose that XH lncRNA may function primarily as 'cis-regulators' of the expression of nearby protein-coding genes, and tend to participate in transcriptional or development regulations as their coding neighbors. All RNA-seq(s) were designed to reveal the differentially expressed genes between wild-type and XH lncRNA knockdown/knockout ESCs during differentiation.

Genomic deletion by CRISPR/Cas9 reveals a critical role for Evx1as/Evx1 locus in regulating embryonic stem cell differentiation

Project description:We report that head to head long noncoding RNAs contribute to transcription and developmental process. Thousands of lncRNAs have been identified in the whole genome, and classified to several subgroups based on the genome position with their coding neighbors. XH, the head to head subgroup is associated with transcription and development in GO analysis. Here, we deleted the promoter and exon1 region which shared by Evx1as/Evx1 XH pair in embryonic stem cells by two sgRNAs-mediated CRISPR. Two homozygous mutants came out from 46 single clones with high efficiency, while two control clones were picked from cells which were only Cas9 transfected. These two mutants failed to activate Evx1 in -LIF differentiation compared to control cells, while Evx1as still have 30% mRNA residual. Meanwhile, we characterized gene expression level among different stages of ESC differentiation and found many differentiated related makers exhibited aberrant regulation, especially endodermal genes. We propose that XH lncRNA and its coding neighbor could regulate each other, and function as a unit to promote ESC differentiation and biological development.

Global identification of growth-related long non-coding RNAs in breast muscle of chicken

Project description:Long non-coding RNAs (lncRNAs) can have potential roles in development of tissues and organs. We selected breast muscle of fast-growing White Recessive Rock chicken (WRR) and slow-growing Xing Hua chicken (XH) to identify lncRNA transcripts by LncRNA-Seq. This study identified 21,993 novel lncRNAs. Among 7,339 differentially expressed lncRNAs, 723 up-regulated and 6,616 down-regulated lncRNAs were found in WRR compared with XH. Of them, five novel lncRNA were antisense transcripts for growth-related genes CACNA1D (unigene 14689_all), IL4I1 (unigene 15355_all), LEF-1 (unigene 19525_all) and FABP1 (unigenes 17536_all and 17537_all) respectively. Meanwhile, 12 other novel lncRNAs were found in the intron or downstream of some known growth-related genes (IGF1, IGF2BP2, IGF2BP3, CACNA1D, IL4I1, LEF-1 and FABP1). In addition, 4,043 SSRs and 200,049 SNPs were identified. Our data revealed the global lncRNA expression pattern in muscle tissue, and contributed a useful genomic resource towards studying the effects of lncRNAs in regulating chicken growth.

Genome-wide profiling of long noncoding RNA expression patterns in chemoresistant breast cancer cells

Project description:Long non-coding RNAs (lncRNAs) are involved in cancer progression. In this study, the lncRNA profiling were analyzed in chemoresistant and sensitive breast cancer cells. We found a group of dysregulated lncRNAs in chemoresistant cells. Expression of dysregulated lncRNAs are correlated with dysregulated mRNAs, and enriched in GO and KEGG pathways related with cancer progression and chemoresistance development. Within those lncRNA-mRNA interactions, some lncRNAs may cis-regulate neighboring protein coding genes and involved in chemoresistance. The lncRNA NONHSAT028712 was then validated to regulate nearby CDK2 and interfere with cell cycle and chemoresistance. Furthermore, we identified another group of lncRNAs trans-regulated gene expression via interacting with different transcription factors (TF). Whereby NONHSAT057282 and NONHSAG023333 was found to modulate chemoresistance and most likely interacted with ELF1 and E2F1 respectively. In conclusion, this study reported for the first time the lncRNA expression patterns in chemoresistant breast cancer cells, and provided a group of novel lncRNA targets in mediating chemoresistance development in both cis- and trans- action mode.

The long noncoding RNA expression profile of hepatocellular carcinoma identified by microarray analysis

Project description:To explore the potential involvement of lncRNAs in hepatocellular carcinoma (HCC) oncogenesis, we conducted lncRNA and mRNA profiling in 3 pairs of human HCC and adjacent normal tissue (NT) by microarray. With abundant probes accounting for 33,045 lncRNAs and 30,215 coding transcripts in our microarray, the number of lncRNAs and coding transcripts that could be detected here is 10,149 and 14,944, respectively. From the data, thousands of lncRNAs and mRNAs were found to bedifferentially expressed (Fold Change≥2.0) in HCC tissues compared with NT and identified 624 lncRNAs and 1050 mRNAs were differentially expressed in all three HCC tissues.Bioinformatic analysis (gene ontology, pathway and network analysis) was performed for further study of these differentially expressed mRNAs.By qRT-PCR analysis in nineteen pairs HCC and adjacent normal tissues, we found that eightl ncRNAs were aberrantly expressed in HCC compared with corresponding NT, which is consistent with microarray data. Additionally, change trends of seven lncRNAs were basically identical to their nearby coding genes. In this study, to explore the potential involvement of lncRNAs in hepatocellular carcinoma (HCC) oncogenesis, we conducted lncRNA and mRNA profiling in 3 pairs of human HCC and adjacent normal tissue (NT) by microarray.
