There is growing evidence that epithelial mesenchymal-transition (EMT) plays significant roles in terms of tumor metastasis. There are a lot of cytokines inducing EMT of tumor cells, EGF is one of the important cytokines.Ezrin is a connexin between the cytoskeleton and the cell membrane, which is closely related to the morphological movement and metastasis of tumor cells.EGF can activate Ezrin and affects cell motility. In recent years, many studies have shown that NF-kB acts as an important transcription factor, involving in the process of EMT...

Miriam Osterfield, Celeste A Berg, Stanislav Y Shvartsman
Understanding the mechanisms driving tissue and organ formation requires knowledge across scales. How do signaling pathways specify distinct tissue types? How does the patterning system control morphogenesis? How do these processes evolve? The Drosophila egg chamber, where EGF and BMP signaling intersect to specify unique cell types that construct epithelial tubes for specialized eggshell structures, has provided a tractable system to ask these questions. Work there has elucidated connections between scales of development, including across evolutionary scales, and fostered the development of quantitative modeling tools...

N-acetylglucosaminyltransferase V (GnT-V), an enzyme that catalyses the formation of the N-linked β-1-6 branching of oligosaccharides, is related to the radiosensitivity of nasopharyngeal carcinoma (NPC). Cetuximab (C225) is an epidermal growth factor receptor (EGFR) inhibitor used as a radiosensitizer in the treatment of NPC. In this study, we used GnT-V as a molecular target to further sensitize cetuximab-treated NPC cells to radiation. The results from two NPC cell lines (CNE1 and CNE2) revealed that the silencing of GnT-V enhanced cetuximab-induced radiosensitivity by decreasing the β-1-6 branching of oligosaccharides on the EGFR...

Bioluminescence is a useful tool for imaging of cancer in in vivo animal models that endogenously express luciferase, an enzyme that requires a substrate for visual readout. Current bioluminescence imaging, using commonly available luciferin substrates, only lasts a short time (15-20 min). To avoid repeated administration of luciferase substrate during cancer detection and surgery, a long lasting bioluminescence imaging substrate or system is needed. A novel water-soluble biotinylated luciferase probe, B-YL (1), was synthesized...

Protein O-fucosyltransferase 1 (POFUT1) fucosylates the epidermal growth factor (EGF)-like domains found in cell-surface and secreted glycoproteins including Notch and its ligands. Although Notch fucosylation is critical for development, and POFUT1 deficiency leads to human disease, how this enzyme binds and catalyzes the fucosylation of its diverse EGF-like domain substrates has not been determined. Reported here is the X-ray crystal structure of mouse POFUT1 in complex with several EGF-like domains, including EGF12 and EGF26 of Notch...

TGF-β is considered a master switch in the pathogenesis of organ fibrosis. The primary mediators of this activity are the SMAD proteins, particularly SMAD3. In the current study, we have developed a cell-penetrating peptide (CPP) conjugate of the HIV TAT protein that is fused to an aminoterminal sequence of sorting nexin 9 (SNX9), which was previously shown to bind phosphorylated SMAD3 (pSMAD3). We determined that specifically preventing the nuclear import of pSMAD3 using the TAT-SNX9 peptide inhibited profibrotic TGF-β activity in murine cells and human lung fibroblasts as well as in vivo with no demonstrable toxicity...

BACKGROUND: Despite encouraging data in terms of neurological outcome, stem cell based therapy for ischemic stroke in experimental models and human patients is still hampered by multiple as yet un-optimized variables, i.e., time of intervention, that significantly influence the prognosis. The aim of the present study was to delineate the optimum time for neural stem cells (NSCs) transplantation after ischemic stroke. METHODS: The NSCs were isolated from 14 days embryo rat ganglion eminence and were cultured in NSA medium (neurobasal medium, 2% B27, 1% N2, bFGF 10 ng/mL, EGF 20 ng/mL and 1% pen/strep)...

Magnetic nanoparticles (MNPs) functionalized with targeting moieties can recognize specific cell components and induce mechanical actuation under magnetic field. Their size is adequate for reaching tumors and targeting cancer cells. However, due to the nanometric size, the force generated by MNPs is smaller than the force required for largely disrupting key components of cells. Here, we show the magnetic assembly process of the nanoparticles inside the cells, to form elongated aggregates with the size required to produce elevated mechanical forces...

Multiple-EGF like domains 10 (MEGF10) is the mammalian homologue of Draper, a Drosophila phagocytosis receptor that plays an important role in synapse elimination and cell type-specific recognition. However, the expression and function of MEGF10 in the brain remain to be elucidated. Therefore, we aimed to clarify the regions and types of neurons that express MEGF10 in the brain, and to determine whether cells expressing MEGF10 possess phagocytic abilities. Our results indicated that MEGF10 is expressed in cholinergic and glutamatergic neurons of the cortex, hippocampus, and substantia nigra...

Although progestin has been used to treat endometrial hyperplasia and endometrial carcinoma (EC), its therapeutic efficacy is limited. In order to improve this, the underlining mechanisms of the effects of progestin need to be elucidated in more detail. In the present study, we examined the involvement of mitogen-inducible gene-6 (MIG6), a negative regulator of the EGF receptor, in the progestin-mediated growth suppression of endometrial epithelia. The immunohistochemical expression of MIG6 was elevated in the early to mid-secretory phases of normal endometrium and also with endometrial hyperplasia after medroxyprogesterone acetate (MPA) therapy...

Preeclampsia is a complication of pregnancy manifested as hypertension-in-pregnancy (HTN-Preg) and often intrauterine growth restriction (IUGR). Placental ischemia could be an initiating event, but the molecular mechanisms are unclear. To test the hypothesis that dimerization of matrix metalloproteinases (MMPs) plays a role in HTN-Preg and IUGR, the levels/activity of MMP-9, tissue inhibitor of metalloproteinase (TIMP-1), and their dimerization forms were measured in the placenta, uterus, and uterine artery of normal pregnant (Preg) rats and a rat model of reduced uteroplacental perfusion pressure (RUPP)...
