IGFBP3 contributes to cell migration and proliferation in an endophytic tongue squamous cell carcinoma cell line

Project description:We previously found that IGFBP3 mRNA levels are higher in endophytic-type human tongue squamous cell carcinoma (TSCC) that is more invasive and more prone to metastasis than exophytic and superficial types. To investigate the roles of IGFBP-3 in SAS cells that express a fluorescent ubiquitination-based cell-cycle indicator (Fucci).

PARVB overexpression increases migration capability and defines high risks for endophytic growth and metastasis in tongue squamous cell carcinoma.

Project description:Tongue squamous cell carcinoma (TSCC) varies in characteristics even in early stages and is mainly classified into three subtypes, which are superficial, exophytic and endophytic types, based on a macroscopic appearance of tumor growth.Of these subtypes, endophytic tumor has a poorer prognosis because of its invasive feature and higher frequency to have metastasis. To understand a molecular mechanism of endophytic subtype and identify biomarkers, we performed comprehensive microarray analysis for mRNAs from clinical biopsy sampleswhich were classified into subtypes and found overexpression of parvin-beta (PARVB) gene significantly related to endophytic type. PARVB is known to play a critical role in actin reorganization and focal adhesions. Knocking down PARVB expression in vitrocaused apparent decreases in cell migration and wound healing, implying that PARVB has a crucial role in cellular motility. Moreover, metastasis-free survival was significantly lowered in patients with higher PARVB expression. Therefore overexpression of PARVB is a candidate biomarker for endophytic tumor and metastasis and may be clinically applicable for decision making of an adjuvant therapy in TSCC. Twenty seven OCT embedded tissues were used to extract total RNA. Then RNAs were amplified, biotinylated, fragmented and hybridized on GeneChip Human Genome U133 plus 2.0 arrays.

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.

The interplay of MMP-8, TGF-β1 and VEGF-C cooperatively contributes to the aggressiveness of oral tongue squamous cell carcinoma

Project description:The study aimed to resolve the mechanisms of protective actions of MMP-8 in oral tongue squamous cell carcinoma. The experiment compares the gene expression levels of control and MMP-8 overexpressing human oral tongue squamous cell carcinoma cells (HSC-3) in stationary and migrating phenotype.

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
