| Introduction | |
| D4-GDI belongs to the family of Rho-GDIs or GDP-dissociation inhibitors for the Rho/Rac family of small G proteins; consisting of RhoGDI-1, D4 GDI/RhoGDI-2 and RhoGDI-3. It inhibits the release of GDP from the Rho proteins, essential for GTP-loading and activation of GTPase activity. D4-GDI is located in the cytoplasm and is involved in the regulation of the membrane association and dissociation cycle of Rho/Rac proteins. It is known to be a substrate for caspase 3 during Fas-mediated apoptosis. D4-GDI is expressed only in hematopoietic tissues, mainly in B and T cells, unlike RhoGDI which is expressed ubiquitously. D4-GDI plays a role in the regulation of lymphocyte activation, survival, and responsiveness. Expression of D4-GDI is also observed in cells of nonhematopoietic neoplasms, including ovarian and bladder cancer cells, suggestive of D4-GDI’s role in progression of human tumors. D4-GDI is expressed in human breast cancer cells. In different human breast cancer cell lines that were studied, cell lines with high invasive activities, for example MDA-MB-231, expressed higher D4-GDI than did weakly invasive and noninvasive cell lines. Intentional disruption of D4-GDI by steadily expressing small interfering RNA (siRNA) against D4-GDI transcripts successfully blocks the motility and invasive potential of MDA-MB-231 cells in vitro. Cells deficient of D4-GDI revert to a normal breast epithelial phenotype characterized by the formation of cysts with a central lumen when grown on Matrigel. D4-GDI reduction is linked to a down-regulation of the cell surface protein ?1-integrin and a loss of cell-matrix adhesion, suggestive of D4-GDI induction of cell invasion by controlling ?1-integrin expression. The expression of ?1-integrin and invasive activities are restored once there’s restitution of D4-GDI expression to the levels found in the parental MDA-MB-231 cells. Therefore it is suggested that D4-GDI may play a significant role in the regulation of breast cancer cell invasiveness. | |
