Abstract
RhoE, a small G protein, is constitutively GTP bound within the cell and can regulate actin cytoskeleton reorganization, leading to the appearance of aggregates of actin filaments. Although emerging evidence suggests that RhoE is causally involved in cancer formation and progression, little is known about its significance in solid cancer, including lung cancer. In the present study, the expression of RhoE was analyzed using Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR), real-time RT-PCR, immunohistochemistry and western blot in 30 patients with Non-Small Cell Lung Cancer (NSCLC). Then the correlation of RhoE overexpression with clinical parameters was evaluated. Furthermore, the possible reasons contributing to the RhoE expression were examined by real-time genomic PCR and mutation analysis on DNA sequence and cDNA sequence. Our results revealed that RhoE expression was dramatically increased in lung cancer tissues compared with adjacent non-tumoral lung tissues (p
