NDRG2 regulates intracellular signals by inhibiting c-Jun phosphorylation and cyclin D expression, therefore inhibiting cell proliferation [16]. NDRG2 overexpression was shown to reduce intracellular -catenin levels and TCF/LEF activity by activating glycogen synthase kinase three (GSK-3) inside a colorectal carcinoma cell line, SW620. The inhibition of TCF/-catenin activity by NDRG2 suppresses tumor metastasis [18]. The MMP (matrix metalloproteinase) loved ones contributes towards the degradation of your extracellular matrix in tumor progression and metastasis [191]. Moreover, NDRG2 expression was shown to be associated with MMP downregulation in clear cell renal cell carcinoma (CCRCC) and hepatocellular carcinoma (HCC) [22,23]. Also, MMP expression is regulated via mechanisms which include ERK1/2 inhibition, NFB signaling regulation, and TGF signaling inhibition by NDRG2 overexpression [17,22,246]. NDRG2 includes a function as a PP2A recruiter, inhibiting NFB signaling by inducing NFB-inducing kinase (NIK) dephosphorylation [27]. NDRG2 was shown to suppress the TGF-1-mediated induction of MMP by way of the regulation of integrin three expression in hepatocarcinoma and integrin six expression in metastatic murine breast cancer cells (4T1), thereby suppressing the activation of latent extracellular TGF- [17,26]. A variety of stimuli, including the IL-6 family members, EGF, and IGF, activate Janu kinase/signal transducer and GW-870086 Protocol activator of transcription (JAK/STAT) signaling [28]. Signal transducer and activator of transcription three (STAT3) plays a role in cell proliferation, survival, and invasion/metastasis as a tumorigenic player [291]. NDRG2 expression suppresses Snail expression at the transcriptional level and epithelial esenchymal transition (EMT) by inhibiting STAT3 [32]. Snail is usually a zinc-finger transcription regulator that inhibits E-cadherin expression and initiates EMT [33]. The silencing of suppressors of cytokine signaling (SOCS-1) contributes to the preferential activation of STAT3 by the JAK pathway [34]. The overexpression of NDRG2 in MBA-MB231 breast cancer cells increases SOCS-1 expression, plus the JAK/STAT3 pathway is negatively regulated by SOCS-1 [35]. Even though you can find reports around the NDRG2-mediated regulation of signal transduction and EMT-inducing transcription element, the precise molecular mechanism has not been totally elucidated. The Warburg impact indicates that cancer cells choose metabolism through glycolysis more than the much much more efficient oxidative phosphorylation pathway which is favored by most other cells. Thus, improved glucose consumption is required, as glucose is a carbon source for anabolic processes to help cell proliferation. An increase in glucose transporters (GLUTs) is expected to enable significant amounts of glucose to be taken up in tumors [369]. GLUT-1 promotes glucose transport across the plas.
