| pubmed-article:20596634 | pubmed:abstractText | Rho GDP dissociation inhibitors (RhoGDIs) are important regulators of the GTP hydrolase activity and biological functions of Rho GTPases. RhoGDI2 has been shown to be a metastasis suppressor in bladder cancer and several other cancers. However, the underlying mechanism, effector targets, and the cognate biological functions of RhoGDI2 are not fully understood. To investigate the possible role of RhoGDI2 in lung cancer tumorigenesis and metastasis, the expression pattern of RhoGDI2 in various lung cancer tissue samples and lung cancer-derived cell lines were profiled at both mRNA and protein levels. Furthermore, possible interplay between PI3K/Akt/mTOR pathway activation/inhibition and RhoGDI2 signalling is examined in lung cancer-related cell lines. Our results suggest that RhoGDI2 is likely to be involved in lung tumor malignancy and metastasis. | lld:pubmed |
