Project description:Hypoxic microenvironment plays important roles in the progression of solid tumors including oral squamous cell carcinoma (OSCC). Long noncoding RNAs (lncRNAs) have gained much attention in the past few years. However, it is not clear whether lncRNAs could regulate hypoxia-adaptation of OSCC, and which lncRNAs participate in this process. Using an lncRNA microarray, we analyzed the aberrant lncRNA expression profiles in OSCC tissues compared with paired normal oral mucosa as well as in hypoxic OSCC cells compared with normoxic OSCC cells. Our data revealed 2053 differentially expressed (Fold Change >= 2.0, P-value <= 0.05) lncRNAs, among which 934 lncRNAs were significantly up-regulated and 1119 lncRNAs were down-regulated in OSCC compared with paired normal mucosa. Six OSCC tissues and paired normal oral mucosa were obtained from 6 patients with OSCC. LncRNA expression profiles were evaluated by an Agilent Human LncRNA Array v3.0 (8 x 60K, Arraystar).

Our microarray also identified 942 lncRNAs that were up-regulated and 507 lncRNAs that were down-regulated in cells cultured under hypoxia compared with those cultured under normoxia (Fold Change >= 2.0, P-value <= 0.05). An OSCC cell line Cal-27 was cultured under either 20% O2 (normoxic) or 1% O2 (hypoxic) conditions. Three samples from each group were obtained for microarray study.

Project description:Lymph node metastasis, a powerful prognostic indicator of oral squamous cell carcinoma (OSCC), is chiefly responsible for cancer death. Long non-coding RNA (lncRNA) is recently addressed to significantly account for modulating OSCC metastasis. Here, we identified a novel alternative splice of Oral Cancer Overexpressed 1 (ORAOV1), ORAOV1-B, which was subsequently validated as an lncRNA and correlated with OSCC lymph node metastasis; significantly increased invasion and migration were observed in ORAOV1-B-overexpressed OSCC cells; In the metastatic model, ORAOV1-B also significantly contributed to OSCC-related lung metastasis. cDNA microarrays was performed to compare up- or down-regulated genes in EV and ORAOV1-B sets of OSCC, which suggested TNFα as a potential downstream of ORAOV1-B and the upregulation of pro-inflammatory genes, indicating the activation of NF-κB pathway. In summary, the novel splice variant ORAOV1-B is an lncRNA, which significantly potentiates OSCC invasion and metastasis by binding to Hsp90 and activating the NF-κB-TNFα loop. Our study implies that ORAOV1-B might serve as an attractive OSCC metastasis intervention target.

Project description:We report the application of Methylated RNA Immunoprecipitation with Next Generation Sequencing and R software package in SCC25 and HAEC. By analysis the m6A peak areas which decorated in the 3' untranslated regions of target functional mRNAs and the entire interval of lncRNA, after that use gene ontology enrichment analysis and pathway enrichment analysis to indicate the explicit correlation to transcription, DNA-templated and pathways, we detect a series of m6A modification in mRNAs and lncRNAs, and explore some key clues in pathways related to OSCC which can guide the further studies on OSCC tumorigenesis and potential targeting.

Project description:chemoresistance frequently leads to therapeutic failure in oral squamous cell carcinoma (OSCC). Recently, studies have reported that lncRNAs play active roles in regulation biological properties of cancer. To understand whether lncRNAs involve in regulating cisplatin sensitivity in TSCC, in this study, we profiled the expression of lncRNAs in two TSCC cell lines(CAL-27 and SCC-9) under cisplatin treatment paired untreated cell lines by LncRNA Array (ArrayStar V3.0).

Project description:Although many protein-coding genes have been identified to be aberrantly expressed in hepatocellular carcinoma (HCC), the mechanisms that account for development and progression of HCC remain unclear. In recent years, long noncoding RNAs (lncRNAs) have been shown to have critical regulatory roles in mammalian cell biology. Many lncRNAs can result in aberrant expression of gene products that may contribute to cancer biology. In this study, we first identified non-overlapping signatures of a small number of lncRNAs that are aberrantly expressed in human HCC compared with paired peritumoral tissues. Then we used real-time PCR to validate five lncRNAs whose expression was altered in HCC compared with paired peritumoral tissues. Using loss-of-function and gain-of-function approaches, we found that an lncRNA (termed lncRNA-HEIH) plays a key role in cell cycle regulation. We further demonstrated that lncRNA-HEIH bound to enhancer of zeste homolog 2 (EZH2) and that this interaction was required for the repression of EZH2 target genes. Together, these results reveal insights into the molecular regulation mechanisms of HCC cell cycle regulation and lead us to propose that lncRNAs may serve as key regulatory hubs in cancer biology. A ten chip study using total RNA recovered from five separate HCC tissues and five corresponding paired non-tumor samples.

Project description:Oral squamous cell carcinoma (OSCC) is a main reason of oral cancer mortality and morbidity. Cancer of oral cavity in central south Asia, ranks among third most common kinds of cancer. The discovery of candidate markers to differentiate normal from malignant cells in clinical diagnosis of OSCC would be of critical importance because this malignancy has poor prognosis. To improve the clinical outcome in OSCC patients, the present study was aimed at identifying robust candidate biomarkers for early OSCC diagnosis and to enhance understanding of the mechanisms of disease progression and pathogenesis. Of particular interest are proteins that can be found in tissue lysates of OSCC tumor vs normal adjacent mucosa samples and secreted in cell line Secretomes of HNSCC for non-invasive detection. We analysed 17 paired human malignant OSCC tissues and normal adjacent tissue in addition to secretomes of 9 HNSCC cell lines. The proteome dataset of OSCC and normal tissues consisted of 5,123 protein groups, including 299 proteins with strong differential expression (p-value <0.01, fold change barrier to ˃+2 and <-2, 205 upregulated and 94 down regulated) and 134 common proteins were also found out of total dataset of 4473 identified proteins of HNSCC cell line secretomes. Functional data analysis revealed that these differential proteins were significantly associated with multiple biological processes. Myogenesis, Fatty Acid Metabolism and KRAS Signaling DN were associated with the proteins downregulated in cancer tissues, while Protein Secretion, Unfolded Protein Response, Spliceosomal complex assembly, Protein localization to endosome and Interferon Gamma Response were enriched in the set of upregulated proteins and these regulated proteins may be classically or non-classically secreted. Furthermore, we found differential enrichment of Creb3L1, ESRRA, YY, ELF2, STAT1 and XBP transcription factors potentially regulating these major pathways.
