We have previously shown that IQGAP3, an intracellular signaling molecule, is responsible for cell proliferation because of its ability to regulate Ras, a proto-oncogene product. In the present study, we showed that IQGAP3 is directly involved in the process of cytokinesis as well, and the underlying molecular mechanisms were also addressed. In addition, expression of the IQGAP3 gene, which is tightly co-related with the state of cell proliferation, as well as the molecular mechanismswith which IQGAP3 regulates Ras, was also investigated.

我们之前已经证明，IQGAP3（一种细胞内信号分子）负责细胞增殖，因为它能够调节 Ras（一种原癌基因产物）。在本研究中，我们表明 IQGAP3 也直接参与胞质分裂过程，并且还阐明了潜在的分子机制。此外，还研究了与细胞增殖状态密切相关的IQGAP3基因的表达，以及IQGAP3调节Ras的分子机制。
