ABSTRACT: Background
Colorectal carcinoma (CRC) represents life-threatening problems worldwide. IQ motif containing GTPase activating protein 1 (IQGAP1) is acting as oncogenesis regulators. RNAi is proposed as promising cancer therapeutics.Objective
The objective of this work to explore the consequences of the IQGAP1 silence as a goal for treating CRC using the HCT166 cells as a model for human colon cancer.Methods
RNAi technology was used to design a short specific sequence of RNA (shRNA) to silence the IQGAP1 oncogene. The impact of IQGAP1 silencing on IQGAPs, Ras, IL-8, and TRAIL was investigated. Furthermore, the effect of IQGAP1 silencing on cell viability, proliferation, apoptosis, and invasive capacity was investigated.Results
The present results revealed that IQGAP1 shRNA-treated HCT166 cells showed no invasive capacity compared to the control cells. The silencing of IQGAP1 induced remarkable downregulation of IQGAP1, RAS (H&K), IL-8, CXCR1, CXCR2, NF-kB, BCL-2, and apoptosis of HCT166 cells. On the contrary, IQGAP2, IQGAP3, DR4, DR5, CASP-3, and BAX genes were significantly up-regulated.Conclusion
The IQGAP1 regulates the expression of IQGAPs, Ras, IL-8 receptors, and the apoptotic network. Therefore, the silence of IQGAP1 is a promising strategy for colon cancer therapy.
