Research on the effect of PRMT5 on the genomic binding sites of ΔNp63α and its impact on the global transcriptomic regulation in the human tongue squamous cell carcinoma cell line UM1.

Project description:By performing PRMT5 knockdown in the human tongue squamous cell carcinoma cell line UM1, we analyzed the effects of this treatment on the global gene transcription level and its impact on the genomic binding capacity of the transcription factor ΔNp63α. Using genomic binding data supplemented with the histone activation marker H3K27ac, we identified a significant impact of PRMT5 on the transcriptional regulatory capability of ΔNp63α.

RNA expression in tongue squamous cell carcinoma, tumour free tongue tissue and control tongue

Project description:Tongue squamous cell carcinoma is a tumour type with rather low five year survival, around 60%. The poor survival rate has been ascribed to late detection, a high frequency of locoregional recurrence, the occurrence of secondary primary tumours and death due to comorbidity. One reason for development of recurrence is thought to be the existence of transformed cells in areas adjacent to the primary tumour, cancerization field effect. The aim of this study was to map the changes in the tumour free tongue tissue adjacent to tongue tumours compared with healthy control tongue tissue to better understand the cancerization field effect. Tissue biopsies were collected from tumour (T) and tumour free tissue adjacent to the tumour (TF) from patients with tongue squamous cell carcinoma. Control tissue was collected from latter border of the tongue of tumour free healthy volunteers (C). All samples were homogenized and RNA was extracted. The RNA was biotin labelled and run on Illumina HT-12 bead chip array.

Whole Transcriptome sequencing TSCC (tongue squamous cell carcinoma)

Project description:Of the multiple anatomical sites represented in oral cancer, squamous cell carcinoma of the tongue (TSCC) shows the highest incidence among younger age group. Chewing betel leaf, areca nut & slaked lime and smoking tobacco are common practises in India which have direct clinical implication in TSCC carcinogenesis. Here, for the first time we define the landscape of genomic alterations in TSCC from the Indian diaspora which would help to identify novel therapeutic targets for clinical intervention and define the genetic basis for TSCC. We performed high throughput sequencing of fifty four tongue samples using whole exome sequencing (n=47, 23 paired normal tumor and 1 unpaired) and transcriptome sequencing (n=17, 10 tumor and 5 normal). Mutation, copy number analysis were carried out using exome sequencing data and transcriptome analysis provided expressed genes and transcript fusions in tongue cancer patients. Further, integrated analysis were performed to identify biologically relevant alterations. Our preliminary analysis revealed presence of most frequently altered mutations in TSCC which includes mutations in TP53, NOTCH1, CDKN2A, USP6, KMT2D etc, consistent with literature. We observed high frequency of CG/T(GC/A) transversions in non-CpG islands, a signature associated with tobacco exposure. Somatic copy number analysis revealed copy number gain in known hallmarks such as CCND1, MYC, ORAOV1 genes along with copy number alteration in novel genes. Significant positive correlation was observed in the genes harbouring copy number gains and showing increased expression.

Transcriptomic Dissection of Tongue Squamous Cell Carcinoma

Project description:The head and neck / oral squamous cell carcinoma (HNOSCC) is a diverse group of cancers, which develop from many different anatomic sites and are associated with different risk factors and genetic characteristics. The oral tongue squamous cell carcinoma (OTSCC) is one of the most common types of HNOSCC. It is significantly more aggressive than other forms of HNOSCC, in terms of local invasion and spread. In this study, we aim to identify specific transcriptomic signatures that associated with OTSCC. Keywords: Disease/Control analysis

Human tongue squamous cell carcinoma cell：Control vs. stable METTL3 knockdown

Project description:Transcriptional profiling of human tongue squamous cell carcinoma cell comparing control untreated SAS cells with stable METTL3 knockdown SAS cells. METTL3 is an important methyltransferase in N6-methyladenosine modification. Goal was to determine the differentially expressed and methylated genes upon METTL3 knockdown.

Circular RNA expression in tongue squamous cell carcinoma patients

Project description:circRNA microarrays were performed with 2 pairs of tongue squamous cell carcinoma and their matched adjacent tissues. The statistical significance of the difference was estimated by t-test. circRNAs having fold changes 1.5 and p-values 0.05 are selected as the significantly differentially expressed. The data from microarray indicated that there were 54 upregulated and 70 downregulated circRNAs in TSCC tissues.
