Treatment of both cell lines with 10 % FBS Dasatinib Bcr-Abl inhibitor for 24 h showed significant up regulation of IL 5, IL 20, and IL 28A expression in mRNA levels, Moreover, real time PCR analysis showed the expression of the receptors of three cytokines, IL 5Ra, IL 20R1, and IL 28AR1 in both 253J and EJ cells, IL 5, IL 20, and IL 28A proteins were observed by immunoblot of protein extracts from both cell lines, IL 5, IL 20, and IL 28A protein expression was increased by adding 10 % FBS, Using immunofluorescence confocal microscopy, we next evaluated the sub cellular localiza tion of IL 5, IL 20, and IL 28A protein in both cell lines. All three cytokines were distributed while in the cytoplasm and in the peri atomic places, IL 5, IL 20, and IL 28A Stimulates MMP 9 Expression via Activation of Transcription Factors NF kB and AP 1 in Bladder Cancer Cells Previous reports demonstrated that MMP 9 expression was strongly related Gene expression to bladder tumor invasion and migration, Our data showed that IL 5, IL 20, and IL 28A triggered the migration and invasion of bladder cancer cells, These results prompted us to examine whether IL 5, IL 20, and IL 28A induces MMP 9 expression. Treatment of both types of cancer cells with IL 5 resulted in significant up-regulation of MMP 9 expression in a concentration and time dependent manner, recognized using gelatin zymography and immunoblot analysis, Comparable effects were observed after treatment with either IL 20 or IL 28A, respectively, In addition, the expression of MMP 2, another matrix metalloproteinase, was also activated in IL 5, IL 20, and IL 28A treated cells, including 253J and EJ cells, The 59 regulatory region of the human MMP 9 promoter contains several consensus motifs for NF kB, AP 1, and Sp 1 transcrip tion components, We reasoned that MMP 9 expression by IL 5, IL 20, and IL 28A could be correlated with increased activity of NF kB, AP 1, and Sp 1 in the nucleus. To this TCID 30675-13-9 end, we conducted an electrophoretic mobility shift assay using nuclear extracts of kidney cancer cells stimulated by IL 5, IL 20, and IL 28A. IL 5, IL 20, and IL 28A induced significant upsurge in NF kB and AP 1 binding activities in 253J cell lines, No particular binding things into Sp 1 were observed in cells treated with some of the interleukins, Nonetheless, in the event of EJ cells, each IL 5 and IL 28A stimulated NF kB binding activity, Increased NF kB and AP 1 binding activities were detected in IL 20 treated EJ cells, Induction of the MAPK and Jak Stat Signaling Pathway in Bladder Cancer Cells Induced by IL 5, IL 20, and IL 28A Since signaling for cytokines primarily activates the Jak Stat and MAPK signal transduction pathways, we next investigated the signaling cascades induced by IL 5, IL 20, and IL 28A in bladder cancer cells. Time course experiments were conducted in 253J and EJ cells.
