Project description:Oral epithelial dysplasias are believed to progress through a series of histopathological stages; from mild to severe dysplasia, to carcinoma in situ, and finally to invasive OSCC. Underlying this change in histopathological grade are gross chromosome alterations and changes in gene expression of both protein-coding genes and non-coding RNAs. Recent papers have described associations of aberrant expression of microRNAs, one class of non-coding RNAs, with oral cancer. However, expression profiling of long non-coding RNAs (lncRNAs) has not been reported. Long non-coding RNAs are a novel class of mRNA-like transcripts with no protein coding capacity, but with a variety of functions including roles in epigenetics and gene regulation. In recent reports, the aberrant expression of lncRNAs has been associated with human cancers, suggesting a critical role in tumorigenesis. Here, we present the first long non-coding RNA expression map for the human oral mucosa. We describe the expression of 325 long non-coding RNAs, suggesting lncRNA expression contributes significantly to the oral transcriptome. Intriguingly, 60% of the detected lncRNAs show aberrant expression in oral premalignant lesions. A number of these lncRNAs have been previously associated with other human cancers. A total of six normal oral samples and ten oral premalignant lesions were used to construct SAGE libraries which were then queried for long non-coding RNA expression profiles. The six normal oral samples were previously deposited as GSE8127.

Project description:This portion of the study evaluated the effects of topical 10% black raspberry gel application on gene expression profiles of premalignant oral lesions. Topical application of the bioadhesive black rasberry gel was observed to modulate gene expression and reduce proinflammatory proteins in human premalignant oral lesions. Keywords: Human oral tissues treated with 10% berry gfel

Project description:This portion of the study evaluated the effects of topical 10% black raspberry gel application on gene expression profiles of premalignant oral lesions. Topical application of the bioadhesive black rasberry gel was observed to modulate gene expression and reduce proinflammatory proteins in human premalignant oral lesions. Experiment Overall Design: Each patient served as their own internal control. A pretreatment specimen of the premalignant lesion was obtained for baseline parameters. Following six weeks of treatment, the treated lesional tissue was removed. All tissue samples were immediately placed in RNA later and placed in a -80 degree freezer until sample preparation.

Project description:Oral submucous fibrosis (OSF) as one of the malignant disorders endures a series of histopathological stages to invasive oral squamous cell carcinoma (OSCC) eventually. The role of long non-coding RNA (lncRNA) expression in OSF malignant progression is still poorly understood. Genome-wide lncRNA expression profiling of normal mucous, OSF and OSCC tissues was performed by RNA sequencing. Bioinformatic methods were applied for differential lncRNA analysis and functional enrichment analysis. Quantitative-RT-PCR was used to verify identified lncRNAs.21 novel transcripts were differentially expressed among all three stages during OSF progression with varied expression levels. Our study firstly comprehensively elucidated lncRNAs expression profile of the process of OSCC premalignant lesion to OSCC.
