Identification of biomarkers for lymph node metastasis in early-stage cervical cancer by tissue-based proteomics.

ABSTRACT:

Background

Pelvic lymph node metastasis (PLNM) is the key to determining the treatment and prognosis of early-stage cervical cancer (CC, I-IIst). The aim of this study was to identify biomarkers for PLNM of CC, I-IIst.

Methods

Two-dimensional fluorescence difference gel electrophoresis and matrix-assisted laser desorption/ionisation-time-of-flight mass spectrometry (MALDI-TOF/TOF MS) were used to identify differentially expressed proteins in primary CC, I-IIst tissue with (n=8) and without (n=10) PLNM. The expression levels of three differential proteins (FABP5, HspB1, and MnSOD) were validated using western blotting and immunohistochemistry. An independent cohort of 105 CC, I-IIst patients was analysed to assess the correlation of FABP5, HspB1, and MnSOD with clinicopatholo
