| Research Abstract |
Identification of pseudopodia proteins leads to a further understanding of malignant phenotypes of tumor cells and novel therapeutic strategies. Proteins in whole cells and pseudopodia fractions were individually solubilized, labeled with a highly sensitive fluorescent dye, and separated using two-dimensional difference gel electrophoresis. Among 2508 protein spots observed, 211 had different intensity between whole cells and pseudopodia fractions (more than fourfold differences and P-value of <0.05). The localization of novel pseudopodia-localizing proteins such as RAB1A, HSP90B, TDRD7, and vimentin was confirmed using immunohistochemical examinations. The previous studies demonstrated that these four proteins may function in the cell migration process. This method will provide insights into the molecular details of pseudopodia and a further understanding of malignant phenotypes of tumor cells and novel therapeutic strategies for lung cancer.
