- Abstract
Comparative proteome analysis was performed between RT4 (grade-1) and T24 (grade-3) bladder cancer cell lines, in an attempt to identify differentially expressed proteins during bladder cancer progression. Among those relatively abundant proteins, seven spots changed more than two-fold reproducibly and identified by peptide mass fingerprinting using mass spectrometry and database search. We found most extensive and reproducible down-regulation of NADP dependent isocitrate dehydrogenase cytoplasmic (IDPc) and peroxiredoxin-II (Prx-II), in poorly differentiated T24 compared to well-differentiated RT4 bladder cancer cell line. Subsequent Western blotting analysis of human biopsy samples from bladder cancer patient revealed significant loss... (More)

We found most extensive and reproducible down-regulation of NADP dependent isocitrate dehydrogenase cytoplasmic (IDPc) and peroxiredoxin-II (Prx-II), in poorly differentiated T24 compared to well-differentiated RT4 bladder cancer cell line. Subsequent Western blotting analysis of human biopsy samples from bladder cancer patient revealed significant loss of IDPc and Prx-II in more advance tumor samples, in agreement with data on cell lines. These results suggest that loss of IDPc and Prx-II during tumor development may involve in tumor progression and metastasis. However, additional investigations are needed on large number of human samples to further verify these findings.
