In this study, we aim to screen metastasis-related proteins in human lung squamous carcinoma (LSC) using laser capture microdissection and a proteomic approach. Twenty two differential proteins were identified from pooled microdissected primary LSC and matched lymph node (LN) metastatic tissues. Expression of the differential protein 14-3-3 sigma was determined by Western blotting and immunohistochemistry. In cell invasion assay, down-regulated 14-3-3 sigma by siRNA increased in vitro invasive ability of HTB-182 and A549 cells, up-regulation of 14-3-3 sigma by pcDNA3.0/14-3-3 sigma decreased in vitro invasive ability of HTB-182 and A549 cells. The data suggest that 14-3-3 sigma is a potential LN metastasis-related protein in LSC, and its dysregulation might play an important role in the LN metastatic process of LSC.
