Abstract

Oral squamous cell carcinoma (OSCC) is the 11th most common cancer worldwide, and is associated with a high death rate. At present, there are no suitable markers for detecting and/or monitoring OSCC in body fluids/tissues. Here, we used 1D SDS-PAGE and MALDI-TOF MS to systematically analyze the secretomes of two OSCC cell lines (OEC-M1 and SCC4). The putative OSCC-related proteins identified in this analysis included the Mac-2 binding protein (Mac-2 BP), which was further found to be overexpressed in OSCC specimens and significantly elevated in the sera of OSCC patients compared to healthy controls. Finally, RNA interference-based knock-down of Mac-2 BP expression in OSCC cells revealed for the first time that Mac-2 BP is involved in regulating growth and motility of OSCC cells.
