Project description:Oral cancer is characterized by poor prognosis and low survival rate despite sophisticated surgical and radiotherapeutic modalities. Lymphatic metastasis of oral cancer is a complex process involving multiple post-transcriptional biological processes. Thus, feasible detection of cancer metastasis in plasma could be challenging and beneficial. We recruited patients with oral squamous cell carcinoma (OSCC), one of the common oral cancer types, and checked the lymphatic metastatic status and profiled small RNA in plasma samples.
Project description:Gene Expression Profiling of Oral Squamous Cell Carcinoma (OSCC) was performed to delineate candidate genes clusters with potential to distinguish normal and tumor tissue from oral cavity. All tissue samples were collected after obtaining written informed consent.
Project description:Gene Expression Profiling of Oral Leukoplakia (OPL) and Early Stage Oral Squamous Cell Carcinoma (OSCC) was performed to delineate candidate gene/s clusters with potential to distinguish normal, OPL and tumor tissue from Gingivobuccal complex. All tissue samples were collected after obtaining written informed consent. The RNA profile of 15 OPL and 34 OSCC samples was compared with 1 independent controls Gingivobuccal complex tissue from healthy donors.
Project description:Oral squamous cell carcinoma (OSCC) is highly heterogeneous and metastatic, and the mechanisms driving OSCC development, progression, and metastasis are poorly understood. We performed multiregional single-cell RNA sequencing on 268,131 cells obtained from tumor core, tumor periphery, adjacent non-tumor tissue, and metastatic lymph node samples from 10 patients with human papillomavirus (HPV)–negative metastatic OSCC.

Project description:To elucidate the potential role of small ncRNAs, such as piRNAs and miRNAs in oncogenesis of Oral squamous cell carcinoma (OSCC), we performed genome wide profiling in three human OSCC cell lines, H357 (tongue squamous cell carcinoma), KB (mouth cancer), Hep-2 (laryngeal cancer), and HOK (Normal human oral keratinocyte) using high-throughput RNA sequencing (RNA-Seq) of small RNAs. We discovered 4854 piRNAs in H357, 5184 in KB, 8340 in Hep-2, and 4735 in HOK, while miRNAs in H357, KB, Hep-2, and HOK were 1538, 1533, 1257, and 1468, respectively. This is the first study to identify both piRNAs and miRNAs in OSCCs, which will serve as a future resource for understanding the molecular mechanisms underlying the complex neoplastic events mediated by these small RNAs. Furthermore, these piRNAs and miRNAs have the potential to be used as biomarkers for OSCC.
Project description:Array Comparative Genomic Hybridization (CGH) profiling of Oral Leukoplakia (OPL) and early stage Oral Squamous Cell Carcinoma (OSCC) was performed to delineate candidate non-random chromosomal loci associated with disease progression and clinico-pathological parameters. The array CGH hybridizations were performed for 24 OPL and 38 OSCC samples with pooled gender matched controls. All tissue samples were collected after obtaining written informed consent.
Project description:Common overexpressing genes were identified in all human oral squamous cell carcinoma tissues and/or cultured cells. Ten oral squamous cell carcinoma tissues and 10 human oral squamous cell carcinoma cell lines were analyzed. Three normal oral mucosa tissues and a human non-neoplastic keratinocyte cell lines were used as control samples.
Project description: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.
Project description:Predictive Value of MicroRNAs in the Progression of Oral Leukoplakias Comparison of 10 samples from non-progressive leukoplakias (did not turn into oral squamous cell carcinoma), with 10 samples from progressive leukoplakias (turned into oral squamous cell carcinoma w/in 5 yrs)
