Description
Background: Information on the carcinogenic potential of chemicals is only availably for High Production Volume products. There is however, a pressing need for alternative methods allowing for the chronic toxicity of substances, including carcinogenicity, to be detected earlier and more reliably. Here we applied advanced genomics to a cellular transformation assay to identify gene signatures useful for the prediction of risk for carcinogenicity. Methods: Genome wide gene expression analysis and qRT-PCR were applied to untransformed and transformed Balb/c 3T3 cells that exposed to 2, 4-diaminotoluene (DAT), benzo(a)pyrene (BaP), 2-Acetylaminoflourene (AAF) and 3-methycholanthrene (MCA) for 24h and 120h, at different concentrations, respectively. Furthermore, various bioinformatics tools were used to identify gene signatures predicting for the carcinogenic risk. Results: Bioinformatics analysis revealed distinct datasets for the individual chemicals tested while the number of significantly regulated genes increased with ascending treatment concentration of the cell cultures. Filtering of the data revealed a common gene signature that comprised of 13 genes whose regulation in cancer tissue has already been established. Strikingly, this gene signature was already identified prior to cell transformation therefore confirming the predictive power of this gene signature in identifying carcinogenic risks of chemicals. Comparison of fold changes determined by microarray analysis and qRT-PCR were in good agreement. Conclusion: Our data describes selective and commonly regulated carcinogenic pathways observed in an easy to use in vitro carcinogenicity assay. Here we defined a set of genes which can serve as a simply assay to predict the risk for carcinogenicity by use of an alternative in vitro testing strategy.

Description
We performed microarray analysis to examine the differential gene expression profiles between Prdm1 (Blimp-1)-deleted and control keratinocytes. Keratinocytes isolated from Prdm1-floxed K5-CreER positive (CKO) mice were cultured in the presence of 4OHT to induce deletion of the Prdm1 allele in vitro. Prdm1-floxed K5-CreER positive (CKO) keratinocytes treated with the ethanol solvent control (EtOH) or Prdm1-floxed K5-CreER negative (control) keratinocytes treated with 4OHT or EtOH served as controls. Microarray analyses revealed that there were 93 genes up-regulated and 109 genes down-regulated by more than 2-fold in the CKO + 4OHT group in comparison with the CKO + EtOH, Ctrl + 4OHT or Ctrl + EtOH groups. Several corneocytes-related genes, including Rptn, Lce1f, Krt1 and Lce1d, are significantly down-regulated and several cytokines/chemokines, including Cxcl1, Cxcl2, Cxcl5 and Il24, are significantly up-regulated upon the deletion of Prdm1 in vitro.

Description
Patient selection and specimen collection. Thirty-six freshly frozen tumor samples were prospectively collected from patients undergoing surgery or biopsy for HNSCC at the University of North Carolina (UNC) at Chapel Hill (21 patients) and Vanderbilt University (15 patients). All tissues were snap-frozen in liquid nitrogen within 30 minutes of surgical resection or biopsy, and kept at -80oC until further processing. All patients consented to participation in this study under protocols approved by IRB at the two institutions.

Description
Protein Kinase C alpha (PKC) is a critical mediator of cell signaling and cancer growth. We show that PKC inhibitors decrease proliferation in squamous cell carcinoma of the head and neck (SCCHN) cells and abrogate growth of SCCHN tumors in mouse xenografts. Analysis of gene expression arrays reveals that PKC regulates cell cycle genes required for DNA synthesis. In particular, PKC increases cyclin E protein expression, cyclinE/cdk2 complex formation, and transcription of cyclin E and E2F target genes. Consistent with this mechanism, expression of cyclin E rescues the block in DNA synthesis caused by PKC inhibition. In SCCHN tissue, PKC and cyclin E expression increase progressively from normal and dysplastic to malignant human head and neck tissue. Furthermore, PKC expression correlates with poor prognosis in SCCHN. These results demonstrate that PKC regulates growth by stimulating DNA synthesis through cyclin E and E2F and identify PKC as a therapeutic target that is highly expressed in aggressive SCCHN.
