Oropharyngeal squamous cell carcinoma (OPSCC) incidence has increased dramatically due to human papillomavirus (HPV); however, associated epigenetic alterations are not well studied. We performed genome-wide DNA methylation analysis using an Infinium 450k BeadArray for clinical OPSCC and non-cancerous samples and cancer cell lines with/without 5-aza-2'-deoxycytidine and/or trichostatin A treatment. Frequent promoter hypermethylation and methylation-associated silencing were detected in 144 genes, which included those involved in cell-cell signaling and neuron differentiation. Read More

In this study, we expanded our recent work showing that ASCT2, a Na+-dependent neutral amino acid transporter that is a major transporter of glutamine uptake in cancer cells, is physically associated with EGFR in human head and neck squamous cell carcinoma cells and in several other types of cancer cells. We found in our current study that ASCT2 can be downregulated by cetuximab, an approved anti-EGFR therapeutic antibody, via cetuximab-induced EGFR endocytosis independently of cetuximab-mediated inhibition of EGFR tyrosine kinase. We further found that ASCT2-EGFR association involves the adaptor-related protein complex 1 gamma 1 subunit (AP1G1), a subunit of clathrin-associated adaptor protein complex 1, which plays a role in membrane protein sorting in endosomes after receptor-mediated endocytosis.

The most widely studied detection for circulating tumor cells (CTCs) in peripheral blood of cancer patients has been based on immunomagnetic enrichment using antibodies against epithelial cell adhesion molecule (EpCAM), which is overexpressed in epithelial cells. A neurotrophin receptor p75 (p75NTR) is expressed in a candidate stem cell fraction in esophageal squamous cell carcinoma (ESCC), which shows significantly higher colony formation, enhanced tumor formation in mice, along with strong expression of epithelial mesenchymal transition-related genes. Here, we describe a method to detect CTCs in ESCC based on the combined expression of EpCAM and p75NTR using flow cytometry, demonstrating the feasibility of expression analysis of multiple cell surface markers in viable cells.

Significant correlations between the response to induction chemotherapy and success of subsequent radiotherapy have been reported and suggest that the response to induction chemotherapy is able to predict a response to radiotherapy. Therefore, induction chemotherapy may be used to tailor the treatment plan to the individual patient with head and neck cancer: following the planned subsequent (chemo)radiation schedule, planning a radiation dose boost, or reassessing the modality of treatment (eg, upfront surgery). Findings from reported trials suggest room for improvement in clinical response assessment after induction chemotherapy, but an optimal method has yet to be identified. Read More
