Project description:The elevation of guanine nucleotide binding protein alpha 12 (GM-NM-112) expression is highly associated with tumor invasiveness in several human cancers. We used an siRNA strategy to deplete GM-NM-112 in oral squamous cell carcinoma (OSCC) cells and analyze the transcriptome profile by the Affymetrix Human Exon 1.0 ST platform. Transcriptome analysis of total RNA samples from OSCC cells. We analyzed OSCC cell samples using the Affymetrix Human Exon 1.0 ST platform. Array data was processed by the Affymetrix Exon Array Computational Tool. No technical replicates were performed.
Project description:Three pairs of human OSCC tissues and normal tissues were collected. Methylated RNA immunoprecipitation sequencing (MeRIP-seq) was used to identify m7G sites on Transcriptome (including lncRNAs, mRNAs and circRNAs) and differences in m7G distribution between OSCC tissues and normal tissues.
Project description:Next-generation sequencing (NGS) has transformed systems-based analysis in the molecular landscapes of various cancer types. The goals of this study are to obtain transcriptomes expressed in human oral squamous cell carcinoma (OSCC) cell lines. The transcriptome profiles of OSCC cell lines (H357, KB and Hep-2) and normal Human oral keratinocytes (HOK) were obtained from the high throughput RNA sequencing sequencing using Illumina Hiseq2500 platform. We obtained 10160, 10251, 10191, 10201 transcripts expressed in HOK, H357, KB, and Hep-2 respectively, which include protein coding genes (PCGs), lncRNAs, pseudogenes and others. Our results showed a set of transcripts that are dysregulated in OSCC, which might be playing some key roles in tumorigenesis process. Further in-depth analysis might provide clues for better understanding of gene function in OSCC.

Project description:Oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral cavity and despite therapeutic advances, late-stage diagnoses continue to negatively affect survival, presenting a continuing challenge for clinicians. Detailed molecular characterization by recent bulk and single-cell RNA-sequencing datasets from OSCC suggest that identification of prognostic biomarkers may lead to more targeted therapies, improving patient outcomes. Development of OSCC is associated with exposure to tobacco, alcohol consumption, and infection with human papillomavirus. The mouse model of 4-Nitroquinoline 1-oxide (4NQO) carcinogenesis produces a spectrum of neoplastic lesions that are a robust model of tobacco-induced OSCC. Specifically, studies have shown that similar to human OSCC, mouse OSCC shows upregulation of the oncogenic master transcription factor p63. We performed complementary loss- and gain-of-function experiments of p63 in mouse 4NQO-transformed OSCC cell lines and utilized RNA-sequencing and ChIP-sequencing to uncover the p63 oncogenic network. By combining our signature with publicly available bulk and scRNA-seq data, we generated a murine p63 signature that we have utilized to better understand the role of p63 in mOSCC. Our analyses have identified several potential biomarkers and conserved pathways that are relevant to hOSCC, as well as highlighted the dynamic role of p63 in migration and invasion.
Project description:To exmaine the PMM1-relative tumor suppression transcriptome in OSCC cells, we preformed the Affymetrix Human Genome U133 Plus 2.0 Array with empty vector, PMM1-wildtype and R150H mutation in Cal-27 cells
Project description:To exmaine the apoptosis independent function of FAS knockout transcriptome in OSCC cells, we preformed the Affymetrix Human Genome U133 Plus 2.0 Array with CRISPR/Cas9 control or FAS knockout in SAS cells
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).
