Genome-scale methylation assessment did not identify prognostic biomarkers in oral tongue carcinomas

ABSTRACT: DNA methylation profiling of heterogeneous head and neck squamous cell carcinoma (HNSCC) cohorts has been reported to predict patient outcome. We investigated if a prognostic DNA methylation profile could be found in tumour tissue from a single uniform subsite, the oral tongue. The methylation status of 83 comprehensively annotated oral tongue squamous cell carcinoma (OTSCC) formalin-fixed paraffin-embedded (FFPE) samples from a single institution were examined with the Illumina HumanMethylation450K (HM450K) array. 83 FFPE primary OTSCC tumour samples were analysed in one experimental run.

<h4>Background</h4>DNA methylation profiling of heterogeneous head and neck squamous cell carcinoma (HNSCC) cohorts has been reported to predict patient outcome. We investigated if a prognostic DNA methylation profile could be found in tumour tissue from a single uniform subsite, the oral tongue.

Transcription profiling of human tongue squamous cell carcinoma (SCC)

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. Experiment Overall Design: 26 OTSCC samples and 12 control samples were analyzed using Affymetrix U133 Plus 2.0 array.

Bone marrow-derived multipotent mesenchymal stromal cells promote tongue cancer invasion by inducing collagen production

Project description:Tumor microenvironment (TME) is an active player in malignant growth and spread. Changes in the composition and structure of TME and extracellular matrix can result in either suppression or facilitation of malignant tumor growth. Carcinoma‐associated fibroblasts, bone marrow-derived multipotent mesenchymal stromal cells (BMMSCs), tumor associated macrophages and other inflammatory cells all affect the composition of TME, proliferation and survival of cancer cells, angiogenesis, invasion and metastasis. The objective of this work was to investigate the effect of the interaction between bone marrow-derived BMMSCs and human oral tongue squamous cell carcinoma (OTSCC) cells in the processes of invasion and gene expression. Co-cultures of OTSCC cancer cells and BMMSCs in 3D organotypic invasion assay were used in addition to cell culture, immunological, microarray, and RNA interference techniques. Total number of 4 samples were analyzed. 2 replicates of cultured human oral tongue squamous cell carcinoma (OTSCC) cells, and 2 replicates of OTSCC cells co-cultured with bone marrow-derived multipotent mesenchymal stromal cells

Characterization of the immune profile of oral tongue squamous cell carcinomas with advancing disease

Project description:We investigated whether a unique immune response was instigated with the development of oral tongue squamous cell carcinomas (OTSCC), with/without nodal involvement, with/without recurrent metastatic disease, or within tumor involved nodes. 110 FFPE samples were collected from a retrospective cohort of 67 OTSCC patients and 10 non-cancerous tongue samples. Targets including CD4, CD8, FOXP3, PD-L1 and PD-1 were analyzed by immunohistochemistry. The Nanostring PanCancer Immune Profiling Panel was used for gene expression profiling. Data were externally validated in the TCGA head and neck (HNSCC), melanoma and lung squamous cell carcinoma (LSCC) cohorts. A 24-immune gene signature was identified that discriminated more aggressive OTSCC cases, and although not prognostic in HNSCC was associated with survival in other TCGA cohorts (improved survival for melanoma, p<0.001 and worse survival for LSCC, p=0.038). OTSCC exhibited concordant gene and IHC features characterized by a TH-2 biased, pro-inflammatory profile with upregulated B cell and neutrophil gene activity and increased CD4, FOXP3 and PD-L1 expression (p<0.001 for all by IHC). Compared to less advanced disease, nodal involvement and recurrent OTSCC did not induce a different immune response although recurrent disease was characterized by significantly higher PD-L1 expression (p=0.004 by SP263, p=0.013 by 22C3, p=0.004 for gene expression). Identification of a gene signature associated with different prognostic effects in other cancers highlights common pathways of immune dysregulation that are impacted by the tumor origin. The significant immunosuppressive signaling in OTSCC indicates primary failure of immune system to control carcinogenesis emphasizing the need for early, combination therapeutic approaches.

A minimal DNA 5-methylcytosine signature of oral tongue squamous cell carcinoma [HumanHT-12 WG-DASL V4.0]

Project description:Oral tongue squamous cell carcinomas (OTSCC) are a homogenous group of aggressive tumors in the head and neck region, with a rising incidence among younger population. The role of altered DNA methylation in OTSCC and its link with clinical parameters has not been fully assessed yet. We performed genome-wide methylation analysis of oral tongue primary tumors (n = 52) using 485, 512 probes and correlated altered methylation with differences in gene expression. We used an ensemble machine-learning algorithm to identify differentially methylated probes and regions predictive of survival, risk habits, nodal status, tumor stage, and HPV infection followed by validation using data from the cancer genome atlas (TCGA) project on oral tongue (n = 24) and tumors from all subsites of head and neck region (n = 50). Whole-genome gene expression profiling was carried out with Illumina HumanHT12 v4 expression BeadChip (Illumina, San Diego, CA) with 21 tumors and their matched adjacent normal tissues. Total RNA was extracted using PureLink RNA mini kit (Invitrogen) and RNA quality was checked on the bioanalyzer using RNA Nano6000 chip (Agilent). RNA samples with poor RIN numbers (â?¤7) on the bioanalyzer chip, indicating partial degradation of RNA were processed using Illumina WGDASL assay and the ones with good RIN numbers (>7) were labelled using Illumina TotalPrep RNA Amplification kit (Ambion) as per the manufacturerâ??s recommendations. Targets were used to hybridize arrays and arrays were processed according to the manufacturerâ??s recommendations. Arrays were scanned using HiScan, Illumina, and the data collected were analyzed with GenomeStudio V2011.1 Gene Expression module 1.9.0 (Illumina) to check for the assay quality control probes. Raw signal intensities were exported from GenomeStudio for transformation, normalization and differential expression analyses using R.
