Project description:To understand the role of areca nut constituents in manifestation of Oral submucous fibrosis, we studied gene expression profile in epithelial cells following areca nut water extract treatment. A comaprison with TGF-beta induced gene expression changes were performed as epithelial cells were predicted to be source of TGF-beta. Control Vs Areca nut 5 ug/ml water extract (5H) (2), Contro Vs TGF-beta (2), Control Vs ALK5 (TbetaRI inhibitor) (2), Control Vs 5H + ALK5 inhibitor (2). (2)- Biological duplicates.

Role of areca nut induced TGF-β and epithelial mesenchymal interaction in pathogenesis of precancerous Oral submucous fibrosis

Project description:To understand the role of areca nut and TGF-β induced gene expression changes in fibroblasts and its contibution in the manifestation of Oral submucous fibrosis, we studied gene expression profile in primary human gingival fibroblast (hGF) cells following treatment with areca nut, TGF-β and both together. Control Vs Areca nut 5 µg/ml water extract (5H) (2), Contro Vs TGF-β (2), Control Vs Areca nut (5 µg/ml) and TGF-β (5 ng/ml) (5H+T) (2). (2)- Biological duplicates.

Long non-coding RNA expression profile associated with malignant progression of oral submucous fibrosis

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.

Gene expression profie of OSMF (Oral Submucous Fibrosis) tissues compared with the expression in normal oral tissues

Project description:ABSTRACT: Background: Oral Submucous Fibrosis (OSF) is a chronic inflammatory disease resulting in progressive fibrosis of the oral soft tissues. Habit of chewing betel quid has been proposed as an important etiological factor in the development of this disease. But the exact mechanism of pathogenesis is still not clear. Methods: We took microarray approach to identify differentially regulated genes in 10 OSF tissues against 8 pooled normal tissues using oligonucleotide arrays. Microarray results have been confirmed by qRT-PCR. Regulation of genes in epithelial and fibroblast cells was studied after treatment with arecoline, TGF-b and LAP followed by qRT-PCR. Results: Total number of genes found to be commonly regulated in OSF (p<=0.05 and Fold change>=1.5) tissues are 5288 and among them 2884 are up-regulated and 2404 are down-regulated. Extra cellular matrix genes that have been reported in OSF such as collagens, fibronectin and cytokines ET1, CTGF and TGF-b1 are among the up regulated genes. The list of up and down regulated genes also includes RARRES1, TGM2, THBS1, CHGB, MMP3, SPP1 and ALOX12, C4orf7 respectively. Analysis of microarray data revealed TGF-? pathway as a principal gene network involved in the development of OSF. Intriguingly, there was no regulation of CTGF and THBS1 in fibroblasts by arecoline. However, TGF-b1 treatment regulated all these genes in both epithelial and fibroblast cells. Conclusion: We demonstrate over expression of novel genes in OSF and suggest that OSF development involves TGF-b pathway in an epithelial-stromal cooperation. Targeting TGF-b signaling could be an alternate strategy to treat OSF. Two-condition experiment: 10 OSF tissues against 8 pooled normal tissues
