Control Samples

Selection of optimal control samples is crucial in expression profiling tumor samples. To address this issue, we performed microarray expression profiling of control samples routinely used in head and neck squamous cell carcinoma studies: human bronchial and tracheal epithelial cells, squamous cells obtained by laser uvulopalatoplasty and tumor surgical margins. We compared the results using multidimensional scaling and hierarchical clustering versus tumor samples and laryngeal squamous cell carcinoma cell lines. A general observation from our study is that the analyzed cohorts separated according to two dominant factors: “malignancy”, which separated controls from malignant samples and “cell culture-microenvironment” which reflected the differences between cultured and non-cultured samples. In conclusion, we advocate the use of cultured epithelial cells as controls for gene expression profiling of cancer cell lines. In contrast, comparisons of gene expression profiles of cancer cell lines versus surgical margin controls should be treated with caution, whereas fresh frozen surgical margins seem to be appropriate for gene expression profiling of tumor samples.

Cutaneous squamous cell carcinoma (cSCC) is a common skin cancer. Most patients who develop metastases (2–5%) present with advanced disease that requires a combination of radical surgery and adjuvant radiation therapy. There are few effective therapies for refractory disease. In this study, we describe novel patient-derived cell lines from cSCC metastases of the head and neck (designated UW-CSCC1 and UW-CSCC2). The cell lines genotypically and phenotypically resembled the original patient tumor and were tumorogenic in mice. Differences in cancer-related gene expression between the tumor and cell lines after various culturing conditions could be largely reversed by xenografting and reculturing. The novel drug susceptibilities of UW-CSCC1 and an irradiated subclone UW-CSCC1-R to drugs targeting cell cycle, PI3K/AKT/mTOR, and DNA damage pathways were observed using high-throughput anti-cancer and kinase-inhibitor compound libraries, which correlate with either copy number variations, targetable mutations and/or the upregulation of gene expression. A secondary screen of top hits in all three cell lines including PIK3CA-targeting drugs supports the utility of targeting the PI3K/AKT/mTOR pathway in this disease. UW-CSCC cell lines are thus useful preclinical models for determining targetable pathways and candidate therapeutics.

Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most fatal malignancies worldwide and despite using various therapeutic strategies for the treatment of HNSCC, the surveillance rate is low. Telomerase has been remarked as the primary targets in cancer therapy. Considering the key regulatory role of epigenetic mechanisms in controlling genome expression, the present study aimed to investigate the effects of two epigenetic modulators, a DNA methylation inhibitor and a histone deacetylase inhibitor on cell migration, proliferation, hTERT gene expression, and telomerase activity in HNSCC cell lines. Methods: Human HNSCC cell lines were treated with Azacitidine and Trichostatin A to investigate their effects on telomerase gene expression and activity. Cell viability, migration, hTERT gene expression, and telomerase activity were studied using MTT colorimetric assay, scratch wound assay, qRT-PCR, and TRAP assay, respectively. Results: Azacitidine at concentrations of ≤1μM and Trichostatin A at 0.1 to 0.3nM concentrations significantly decreased FaDu and Cal-27 cells migration. The results showed that Azacitidine significantly decreased hTERT gene expression and telomerase activity in FaDu and Cal-27 cell lines. However, there were no significant changes in hTERT gene expression at different concentrations of Trichostatin A in both cell lines. Trichostatin A treatment affected telomerase activity at the high dose of 0.3 nM Trichostatin A. Conclusion: The findings revealed that unlike histone deacetylase inhibitor, Azacitidine as an inhibitor of DNA methylation decreases telomerase expression in HNSCC cells. This might suggest the potential role of DNA methyltransferase inhibitors in telomerase-based therapeutic approaches in squamous cell carcinoma.
