Abstract


OBJECTIVE
Comparison of protein expression by two-dimensional gel electrophoresis (2-DE) in normal myometrium and uterine leiomyoma in Korean women.
METHODS
Normal myometrium and uterine leiomyoma tissues were solubilized with 2-DE buffer and the first dimension of PROTEAN IEF CELL, isoelectric focusing (IEF), was performed using pH4-8 linear IPG strips of 17 cm. And then running 12% sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS- PAGE) and sliver stain. Scanned image analyzed using PDQuest 2-D softwareTM. Protein spot spectrum was identified by assisted laser desorption/ionization-time of fighting (MALDI-TOF) and the protein mass spectrums identification were performed by searching protein databases of Swiss-prot/TrEMBL, Mascot and MS-FIT.
RESULTS
In this study, we found 17 up-regulated proteins (phosphate carrier protein, 60 kDa heat shock protein, acidic calcium-independent, glutathione transferase omega, chloride intracellular channel 4, Ras-related protein Rab-11B, phosphatidylinositol transfer protein alpha isoform, type II keratin subunit protein, Cofilin 2 isoform 1, transgelin, ATP carrier protein, alpha-catenin homolog, parkinson disease 2, apo-cellular retinoic acid binding protein II, osteoglycin preproprotein, proteasome activator subunit 1 isoform, Unnamed protein) and 7 down-regulated proteins (Serum amyloid P component, annexin IV, alpha 1 actin precursor, hypoxanthine-guanine phosphoribosyltransferase, tumor necrosis factor receptor superfamily member EDAR precursor, peroxiredoxin 2, translation elongation factor EF-Tu precursor) between myometrium and leiomyoma.
CONCLUSION
2-DE offer total protein expression between normal myometrium and uterine leiomyoma, and searching of differently expressed protein for the diagnostic markers of leiomyoma.
