Abstract

Globally, breast cancer is the second most common cancer amongst women. Although biomarker discoveries through various proteomic approaches of tissue and serum samples have been studied in breast cancer, urinary proteome alterations in breast cancer is least studied. Urine, being a non-invasive biofluid and a significant source of proteins has potential in early diagnosis of breast cancer. The present study used complementary quantitative gel based and gel free proteomic approaches to find a panel of urinary protein markers that could discriminate HER2 enriched (HE) subtype breast cancer from the healthy controls. A total of 183 differentially expressed proteins were identified using three complementary approaches viz. 2D-DIGE, iTRAQ and SWATH. The differentially expressed proteins were subjected to various bioinformatic analyses for deciphering the biological context of these proteins using PANTHER, DAVID and STRING. Multivariate statistical analysis was undertaken to identify the set of most significant proteins, which could discriminate HE breast cancer from healthy controls. Immunoblotting and MRM based validation in a separate cohort testified a panel of 21 proteins such as ZA2G, A2GL, RET4, ANXA1, SAP3, SRC8, GELS, KNG1, CO9, CLUS, CERU and A1AT could be a panel of candidate markers that could discriminate HE breast cancer from healthy controls.
