英文摘要
This subproject is one of many research subprojects utilizing the resources
provided by a Center grant funded by NIH/NCRR. Primary support for the subproject
and the subproject's principal investigator may have been provided by other sources,
including other NIH sources. The Total Cost listed for the subproject likely
represents the estimated amount of Center infrastructure utilized by the subproject,
not direct funding provided by the NCRR grant to the subproject or subproject staff.
We have used a label-free quantitative nanoESI-HPLC mass spectrometric method to
perform comparative proteomics analysis on the urine from control rats and rats bearing
4-hydroxybutyl(butyl)nitrosamine induced bladder tumors. In this study the urinary
proteins from control animals (n = 10) and from those with palpable bladder tumors (n =
10) were digested sequentially with endoprotease Lys C and trypsin after reduction
and alkylation. The peptides were separated with nanoflow- reversed phase HPLC,
ionized with nanospray ionization, and analyzed with a hybrid linear quadrupole Fourier
transform ion cyclotron mass spectrometer (FT-MS). Parent mass scans were acquired
over a 2 h linear gradient of acetonitrile for each of the 20 samples. The mass spectra
from the control and tumor-bearing groups were aligned and the individual accurate
mass signals were quantified using Rosetta ElucidatorTM software. The isotope groups
with statistically significant different areas (P < 0.01) between the two groups were
used to produce the accurate m/z values for directed acquisition of tandem mass
spectra to sequence the peptide and identify the protein differences between the two
groups. Among the proteins that were found to be increased in the tumor bearing urine
(after excluding the hepatic-derived and well-recognized blood proteins e.g. albumin,
hemopexin, hemoglobin) were meprin, E-cadherin, hyaluronan receptor, glycam,
retinoblastoma binding protein.
