RT Journal Article SR Electronic T1 Expression Patterns of Kinin-Dependent Genes in Endometrial Cancer JF International Journal of Gynecologic Cancer JO Int J Gynecol Cancer FD BMJ Publishing Group Ltd SP 937 OP 944 DO 10.1097/IGC.0b013e318259d8da VO 22 IS 6 A1 Joanna Orchel A1 Lukasz Witek A1 Malgorzata Kimsa A1 Barbara Strzalka-Mrozik A1 Magdalena Kimsa A1 Anita Olejek A1 Urszula Mazurek YR 2012 UL http://ijgc.bmj.com/content/22/6/937.abstract AB Objective The present study has focused on the identification of the differences between expression patterns of kinin-dependent genes in endometrial cancer with the use of real-time quantitative reverse transcription polymerase chain reaction and oligonucleotide microarray.Materials and Methods The study group consisted of 50 endometrium samples collected from women with endometrial cancer. Gene expression of kinin receptors BR1 and BR2 was evaluated with real-time quantitative reverse transcription polymerase chain reaction. The analysis of the expression profile of genes related to the kinin mitogenic signal transduction pathway was performed using HG-U133A oligonucleotide microarrays.Results The transcriptional activity of the B1 receptor for kinins increased in patients with grade 1 (G1) and grade 2 (G2) endometrial cancer when compared to the control group, whereas it decreased in patients with grade 3 (G3) endometrial cancer. The expression of the B2 receptor showed a growing trend reaching the peak in the G2, whereas G3 was characterized by a decrease in the gene transcriptional activity. Significant differential gene expression was recorded for GNB1, PRKAR1A, KRAS, MAP2K2, GNG5, MAPK1, ADCY9, GNG11, JUN, PRKCA, PRKACB, FOS, PLCB4, ADCY8, and GNG12.Conclusion The expression changes in kinin-dependent genes might cause disturbance in the underlying biological processes, which could be important for the pathogenesis of endometrial cancer. This will eventually help to improve treatment strategies for patients with endometrial cancer in the future.
