    • Abstract

       

      To analyse the mechanism of tumourigenic transformation of NIH3T3 cells at the transcriptional level, we used cancerogen 3-methylcholanthrene (3-MCA) and cancerogenic substance phorbol-12-myristate-13-acetate (PMA) to transform NIH3T3 cells and the assessment of transformation was performed using Giemsa staining and methylcellulose colony formation assay. Changes in gene expression profile were detected by MouseGenome 430 2.0 microarray; and quantitative real-time polymerase chain reaction and Western blotting were used to verify the expression changes of mRNAs and proteins, respectively. With the aidof bioinformatics method, five signalling pathways were identified to participate in different stages of NIH3T3 cell transformation. Further, our study suggested that oncogenes Cyclin A, Myc, Jun and the tumour suppressor gene Ppm1l may play important roles in these pathways.
