Project description:To identify TGF-β regulated lncRNAs in glioblastoma, we performed a genome-wide microarray screen in T98G glioma cells. T98G cells were treated with 10 ng/ml TGF-β (24h) and differentially expressed lncRNAs were identified using microarray in comparison with control cells.

Project description:The role of TGF-M-NM-2-induced epithelial-mesenchymal transition (EMT) in cancer cell dissemination is well established, but the involvement of lncRNAs in TGF-M-NM-2 signaling is still unknown. In this study, we observed that the lncRNA-Activated by TGF-M-NM-2 (lncRNA-ATB) was upregulated in hepatocellular carcinoma (HCC) metastases and associated with poor prognosis. lncRNA-ATB promotes the invasion-metastasis cascade, which suggest that lncRNA-ATB, a mediator of TGF-M-NM-2 signaling, could predispose HCC patients to metastases and may serve as a potential target for anti-metastatic therapies. SMMC-7721 hepatoma cells were continuously treated with 10 ng/ml of recombinant TGF-M-NM-21 for 21 days. Total RNA recovered from three untreated cells and three treated cells were used to acquire different expression profiles of mRNAs and lncRNAs.

Project description:Long non-coding RNAs (lncRNAs) are emerging as pivotal modulators of signaling trnasduction, and thereby regulate multiple pathological processes including cancer. TGF-beta signaling contributes to cancer metastasis by inducing epithelial-to-mesenchymal transition (EMT). To screen lncRNAs that are induced by TGF-beta, MCF10A-M1, MCF10A-M2 and MDA-MB-231 cells were stimulated with TGF-beta (5 ng/mL) fo 0 h, 2 h, 8 h and 24 h. RNA was extracted from those cells and analyzed by RNA-seq.

Project description:It is well understood how proteins regulate cell fate, both in normal development and disease. However, a substantial fraction of the genome is transcribed in a cell type- specific manner, producing long non-coding RNAs (lncRNA) rather than protein- coding transcripts. Here we systematically characterize transcriptional dynamics (both mRNA and lncRNA) during hematopoiesis and in hematological malignancies. We present de novo assembled transcriptome models and expression values for hematopoietic lncRNAs. We found lncRNAs to be regulated during differentiation and misregulated in disease. We assessed lncRNA function via an in vivo RNAi screen in a model of acute myeloid leukemia. With this approach, we identified several lncRNAs essential for leukemia maintenance, and found that a number act by promoting leukemia stem cell signatures. Leukemia blasts show a myeloid differentiation phenotype when these lncRNAs were depleted, and our data indicates that this effect is mediated via effects on the c-MYC oncogene.

Project description:Introduction: Glioblastoma (GBM) invasion studies have focused on coding genes, while few studies evaluate long non-coding RNAs (lncRNAs), transcripts without protein-coding potential, for role in GBM invasion. We leveraged CRISPR-interference (CRISPRi) to evaluate invasive function of GBM-associated lncRNAs in an unbiased functional screen, characterizing and exploring the mechanism of identified candidates. Methods: We implemented a CRISPRi lncRNA loss-of-function screen evaluating association of lncRNA knockdown (KD) with invasion capacity in Matrigel. Top screen candidates were validated using CRISPRi and oligonucleotide(ASO)-mediated knockdown in three tumor lines. Clinical relevance of candidates was assessed via The Cancer Genome Atlas(TCGA) and Genotype-Tissue Expression(GTEx) survival analysis. Mediators of lncRNA effect were identified via differential expression analysis following lncRNA KD and assessed for tumor invasion using knockdown and rescue experiments. Results: Forty-eight lncRNAs were significantly associated with 33-83% decrease in invasion (p<0.01) upon knockdown. The top candidate, LINC03045, identified from effect size and p-value, demonstrated 82.7% decrease in tumor cell invasion upon knockdown, while LINC03045 expression was significantly associated with patient survival and tumor grade(p<0.0001). RNAseq analysis of LINC03045 knockdown revealed that WASF3, previously implicated in tumor invasion studies, was highly correlated with lncRNA expression, while WASF3 KD was associated with significant decrease in invasion. Finally, WASF3 overexpression demonstrated rescue of invasive function lost with LINC03045 KD. Conclusion: CRISPRi screening identified LINC03045, a previously unannotated lncRNA, as critical to GBM invasion. Gene expression is significantly associated with tumor grade and survival. RNA-seq and mechanistic studies suggest that this novel lncRNA may regulate invasion via WASF3.

Project description:We conducted a genome-wide screen by clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 library to identify genes which are particularly resistant to EGFRvIII GBM cells under the chemo-stress of TMZ. In vitro and in vivo validation of EGFRvIII-specific targets revealed several strong hits, including E2F6. Mechanistic studies demonstrated that E2F6 reveals its resistance to TMZ through NF-κB and TMZ inducement.EGFRvIII GBM cells under the chemo-stress of TMZ.
