To compare the similarities of gene expression profile between the USC-HN1 cells and HNSCC tumor biopsy samples, we focused on the upregulated genes in USC-HN1 cells. A total of 328 genes with p < 0.05 and log2 fold 1 in USC-HN1 cells compared with previous results from normal tonsils were identified. Many up-regulated genes identified in USCHN1 cells were also present in HNSCC biopsies (Table 4). These common genes were classified into various categories of biological functions including those related to immune response such as MIF and CD24, which were currently identified in HNSCC [6]. Other signatures of up-regulated genes in USC-HN1 cells include ATP5H, HSP27, FABP5, E-cadherin, EIF4G2, KRT18 and KRT8, RPLP0 and RPS18, which are associated with various biological processes such as cell growth and maintenance, cell cycle regulation, metabolism, and protein translation and synthesis (Table 4).RNA was extracted from USC-HN1 and FaDu cell lines, treated with DNase, and analyzed against Universal Human Reference RNA. Gene amplification was normalized to GAPDH. Analysis of oncogenes and cytokines depict an overall similar profile for both USC-HN1 and FaDu. C-myc, c-Kit, VEGFa, and TGF-B1 are significantly upregulated in USC-HN1 compared to FaDu; IL-1B was significantly down-regulated.Activated Notch1 analysisNotch1 protein levels were determined by Western blot for the USC-HN1 cell line in comparison to expression levels seen in positive (Karpas 299) and negative (Siha) cell line controls. Based upon these studies, USC-HN1 demonstrated an increased level of activated Notch1 protein at levels equal to or higher than the Karpas 299 positive control (Figure 9).Microarray gene expression profilingMicroarray gene expression analysis was performed on isolated total RNA from USC-HN1 cells and comparedDiscussion We describe the clinical presentation of an invasive well-differentiated maxillary HNSCC and the establishment of the USC-HN1 cell line from the primary tumor biopsy. Of note, patient NR was a non-smoker and did not receive preoperative radiotherapy or chemotherapy. Her tumor was consistent with a diagnosis of primary HNSCC on presentation by tissue histology and immunostaining for HNSCC markers. The USC-HN1 cell line was established in culture approximately 4 weeks after seeding by isolation from co-existing fibroblastic monolayers which grew from the explanted cultures. USCHN1 shares many characteristics with the primary tumor and has a phenotype typical of an advanced HNSCC. The doubling time.
