Abstract
The aim of the present study was to detect differentially expressed genes in human bladder cancer cell lines using a non-radioactive RNA fingerprinting technique (arbitrarily primed polymerase chain reaction of RNA, RAP-PCR). The two clonal urothelial cancer cell lines, RT4 and J82, show different growth kinetics upon stimulation with EGF. By RAP-PCR we detected changes in band patterns for J82 cells treated with EGF but not for RT4 cells. Polymorphic fragments were further characterized and sequences from two of these gave a perfect match to the coding sequence of the human tropomyosin gene TM30(pl) and the human MAC30 gene, respectively. In accordance with the results of RAP-PCR downregulation in EGF-stimulated J82 cells could be demonstrated by reverse transcription PCR.
