Identification of a cancer driver lncRNA in DNA damage response

ABSTRACT: We report that the lncRNA SCAT7 (ELF3-AS1) is involved in the activation of the DNA damage response in cisplatin resistant LUAD cells, akin cisplatin in sensitive cells. Therefore SCAT7 is a potential therapeutic target for drug resistant cancers

Knockdown of lncRNA ELF3-AS1 in two gastric cancer cell lines

Project description:Our data showed that ELF3-AS1 was a nuclear lncRNA, and its biofunction in cancers is largely unknown to date. To explore the function of lncRNA ELF3-AS1 in gastric cancer, loss-of-function study was performed in SGC7901 and AGS cell lines. RNA sequencing studies showed that the expression of almost all the histone coding genes were significantly increased after knocking down of ELF3-AS1 in SGC7901 and AGS cell lines.

Knockdown of ILF2/ILF3 (NF45/NF90) in the gastric cancer cell line SGC7901

Project description:Our data showed that lncRNA ELF3-AS1 could bind on the exon1 of ELF3-201 to form a double-stranded RNA molecule. This double-stranded RNA could interact with ILF2/ILF3 complex. To explore the biofunction of the interaction between ELF3-AS1 and ILF2/ILF3 complex, loss-of-function studies regarding ILF2 and ILF3 were performed in SGC7901 cell line. RNA sequencing studies showed that knockdown of ILF3 significantly decreased ELF3-AS1, while knockdown of ILF2 significantly increased ELF3-AS1 and NF90 expression. Our data revealed that ILF2/ILF3 complex interacted with ELF3-AS1/ELF3 double-stranded RNA and regulated their transcripts stability.

Identification of differentially expressed miRNAs after knockdown of ELF3-AS1 in gastric cancer

Project description:In this study, we used miRNA sequencing to analyze and identify possible miRNAs that can be regulated by and ELF3-AS1 in gastric cancer. The results showed that lncRNA ELF3-AS1 knockdown decreased the expression of miR-33a/b and miR-203a. Due to miR-33a/b and miR-203a were able to target SNAI2 expression, and ELF3-AS1 knockdown significantly upregulates SNAI2 expression, we speculated ELF3-AS1 may negatively regulate SNAI2 expression through positively regulating the expression of miR-33a/b and miR-203a in GC.

A novel lncRNA, LUADT1 promotes lung adenocarcinoma proliferation by epigenetic suppression of p27

Project description:Long noncoding RNAs (lncRNAs) are known to regulate the development and progression of various cancers, however, few lncRNAs have been well characterized in lung adenocarcinoma (LUAD). Understanding the expression profile of lncRNAs and protein-coding genes is critical to develop new diagnosis and treatment strategies for LUAD and improving the prognosis of diagnosed patients. Five female LUAD patients with no smoking history were selected to profile lncRNA and protein-coding gene expression with microarrays. Paired tumor tissues and adjacent nontumor tissues were collected and confirmed by pathologists.

HHIP-AS1 lncRNA promotes tumorigenicity in human SHH-driven brain tumors

Project description:Long non-coding RNAs (lncRNAs) comprise a diverse class of gene expression regulators with emerging roles in many biological processes including cancer. Here we show that the expression of the lncRNA Hedgehog Interacting Protein Antisense 1 (HHIP-AS1) is a hallmark feature of human SHH-driven tumors. Importantly, loss of HHIP-AS1 leads to reduced tumor growth in SHH-driven tumors in vitro and in vivo. Our results demonstrate the power of cross-entity transcriptome-wide comparisons to identify novel epigenetic–regulatory lncRNA circuitries underlying human cancers.

Identification of interacting proteins of lncRNA HIF1α-AS1

Project description:LncRNA Hypoxia-inducible factor 1α-antisense 1 (HIF1α-AS1) is located on the antisense strand of the important Hypoxia-inducible factor 1α (HIF1α) gene, but being transcribed in antisense direction along the HIF1α promoter. Here we used the 3’end biotinylated HIF1a-AS1 RNA and a control RNA for RNA Pulldown and searched for interacting proteins in nuclear extracts of human umbilical vein endothelial cells (HUVEC).

DNA methylation profiling of lung adenocarcinomas and patient-matched non-malignant lung

Project description:Gene function in cancer is often cell type-specific. The epithelial cell-specific transcription factor ELF3 is a documented tumour suppressor in many epithelial tumours yet displays oncogenic properties in others. Here, we show that ELF3 is an oncogene in the adenocarcinoma subtype of lung cancer (LUAD), providing genetic, functional, and clinical evidence of subtype specificity. We discover a region of focal amplification at chromosome 1q32.1 encompassing the ELF3 locus in LUAD which is absent in the squamous subtype. Gene dosage and promoter hypomethylation affect the locus in up to 80% of LUAD analysed. ELF3 expression was required for tumour growth and a pan-cancer expression network analysis supports its subtype and tissue specificity. We further show that ELF3 displays strong prognostic value in LUAD but not LUSC. We conclude that, contrary to many other tumours of epithelial origin, ELF3 is an oncogene and putative therapeutic target in LUAD.

Circadian lncRNA ADIRF-AS1 binds PBAF and regulates renal clear cell tumorigenesis

Project description:We identified ADIRF-AS1 as a BMAL1-CLOCK regulated circadian lncRNA. Loss of ADIRF-AS1 in U2OS cells altered rhythmicity of clock-controlled genes and expression of genes associated with cell adhesion and the extracellular matrix (ECM) but did not affect neighboring genes in cis. Affinity based enrichment of U2OS ADIRF-AS1-interacting proteins identified all components of the tumor suppressive PBAF (PBRM1/BRG1) complex. Because PBRM1 is a tumor suppressor mutated in 40% of clear cell renal carcinoma (ccRCC) cases, we studied ccRCC 786O cells and also found PBRM1 bound to ADIRF-AS1. Reducing ADIRF-AS1 expression in 786O and A498 ccRCC cells decreased expression of PBAF-suppressed genes, consistent with ADIRF-AS1 acting to antagonize the function of PBAF. Loss of PBRM1, however, rescued PBAF responsive cell cycle genes in ADIRF-AS1 KO 786O ccRCC cells. Importantly, ADIRF-AS1 expression correlates with survival in human ccRCC, particularly in PBRM1 wild-type, but not mutant PBRM1 tumors. In this regard, loss of ADIRF-AS1 did not affect in vitro 786O cell growth, but strikingly eliminated in vivo tumorigenesis, which was partially rescued by concurrent loss of PBRM1. This rescue, however, requires Matrigel, suggesting a PBRM1-independent function of ADIRF-AS1 in regulating the ECM. Collectively, our findings suggest that ADIRF-AS1 functions partly to antagonize the tumor suppressive effect of the PBAF complex and behaves as an unforeseen BMAL1-regulated, oncogenic lncRNA.
