The transcription activity of NF-��B promoter in siCXCR4-1 and siCXCR4-2 groups was 51.3% and 33.4%, respectively, compared with the control group (P? http://www.selleckchem.com/products/SRT1720.html over-expressed in a variety of malignant tumors, including glioma, colorectal cancer, breast cancer, lung cancer, prostate cancer, and cervical cancer (Chaudary et al., 2013; Gillies et al., 2013; Hu et al., http://www.selleckchem.com/products/Adrucil(Fluorouracil).html 2013). It can activate the downstream signal transduction molecules and cytokine production, and can impact the cell adhesion and invasion through complex signaling processes. Several studies have shown that inhibiting the CXCR4 expression in tumor cells could suppress tumor metastasis (Wang et al., 2013). Therefore, CXCR4 is considered as a new target for tumor treatment. (Gil et al., 2013). E-cadherin is important for cell�Ccell adhesion invasion. It maintains the structural integrity of epithelial tissues. CD44 is also an important adhesion molecule. An abnormal CD44 and E-cadherin expression may worsen the degree of tumor malignancy (Shiota et al., 2010; Faber et al., 2013; Wang et al., 2013). The results of our study demonstrated that CXCR4 silencing decreased the adhesion potential of tumor cells in vitro by decreasing CD44 expression and increasing E-cadherin expression. Matrix metalloproteinases (MMPs) belong to the family of proteolytic enzymes. They can almost degrade all the ingredients of the extracellular matrix and release cytokines including TGF-��, IL-6, and IL-8. The expression levels of MMP-2/-9 are closely associated with the degradation of extracellular matrix and tumor cells metastasis (Huang et al., 2012). p53 and p21 are important tumor suppressor genes which could suppress tumor metastasis and block the cell cycle by repairing the DNA damage (Wang et al., 2013). Our results showed that the expression levels of MMPs and the http://en.wikipedia.org/wiki/MERTK production of TGF-��, IL-6, and IL-8 were decreased, whereas the expression levels of p53 and p21 were increased, thereby inducing the down regulation of tumor invasion potential in vitro. The phosphorylation of AKT and PTEN is a type of carcinogenesis/anti-carcinogenesis interactive signal transduction pathway (Wu et al., 2013). PTEN is a tumor suppressor gene and the phosphorylation of PTEN could inhibit the phosphorylation of AKT, which enhances the tumor metastasis ability. NF-��b is an important transcription factor regulated by the AKT activity, and is involved in many physiological processes of cells.
