Abstract

To further explore the mechanism of p38 MAP kinase in regulation of JB6 Cl41 cell transformation. cDNA array was employed to scan the differential expression genes between DN-p38 cells and CMV-neo JB6 Cl41 cells after EGF stimuli. We found that up-expression genes including oncogenes and tumor suppressor genes, p53-associated protein, transcription repressors, apoptosis-associated genes, and growth arrest and DNA damage-inducible protein 153 were detected in DN-p38 cells, but low expression in CMV-neo JB6 Cl41 cells after EGF treatment. Meanwhile, some proto-oncogenes, such as c-Myc, and signal transducer and activator of transcription 1 (STAT1) were lowly expressed in EGF-stimulated DN-p38 cells, but had relatively high expression level in CMV-neo JB6 Cl41 cells under the same stimuli. Four of the differential expression genes were further confirmed by quantitative RT-PCR analysis. Our results indicate that p38 MAP kinase is involved in EGF-induced JB6 Cl41 cell transformation through effecting on more genes expression levels including transcription factors, proto-oncogene, apoptosis-related genes and growth arrest genes.
