The Wnt/β-catenin pathway is one of the most common pathways dysregulated in breast cancer, and may, therefore, be a potential-therapeutic target. We have investigated the effects of PNU-74654 in breast cancer, as a Wnt/β-catenin inhibitor, either alone or in combination with fluorouracil (5-FU). PNU-74654 suppressed cell growth at an IC 50 of 122 ± 0.4 μmol/L and synergistically enhanced the antiproliferative activity of gemcitabine by modulating the Wnt pathway. Using a 3D cell culture model, we found that the PNU-74654 caused tumor shrinkage. It reduced the migration of MCF-7 cells (by an 18% reduction in invasive behavior) after the treatment with PNU-74654 through perturbation of E-cadherin and MMP3/9. PNU-74654/5-FU combination enhanced the percentages of cells in S-phase and significantly increased apoptosis. Moreover, our data showed that this agent was able to inhibit the growth of tumor in a xenograft model, although this effect was more pronounced in the animals treated with PNU-74654 plus 5-FU. These data show the ability of PNU-74654 to specifically target Wnt pathway, interfere with cell proliferation, induce-apoptosis, reduce-migration, and synergistically interact with 5-FU, supporting further studies on this novel therapeutic-approach for breast cancer. 相似文献

Colorectal cancer (CRC) is the leading cause of cancer death worldwide. Dysregulation of RAS/MAPK signaling axis is frequently found in CRC patients. The RAS/MAPK axis regulates cancer cell proliferation, apoptosis, inflammation, migration, and metastasis. Oncogenic or tumor-suppressor microRNAs (miRNAs) for RAS/MAPK signaling play a key role in the pathogenesis of CRC and are considered as novel potential biomarkers for diagnosis and prognosis of human malignancies. This review summarizes the current knowledge of mechanisms of action of RAS/MAPK miRNAs in the development and progression of CRC for a better understanding and hence a better management of this disease. 相似文献

Background
β-catenin is an essential mediator of canonical Wnt signaling and a central component of the cadherin-catenin epithelial adhesion complex. Dysregulation of β-catenin expression has been described in pancreatic neoplasia. Newly published studies have suggested that β-catenin is critical for normal pancreatic development although these reports reached somewhat different conclusions. In addition, the molecular mechanisms by which loss of β-catenin affects pancreas development are not well understood. The goals of this study then were; 1] to further investigate the role of β-catenin in pancreatic development using a conditional knockout approach and 2] to identify possible mechanisms by which loss of β-catenin disrupts pancreatic development. A Pdx1-cre mouse line was used to delete a floxed β-catenin allele specifically in the developing pancreas, and embryonic pancreata were studied by immunohistochemistry and microarray analysis. 相似文献16.

β-Casein is one of the major components of the milk micelles of most mammals and has been shown to exhibit in vitro chaperone-like
activity. Glycerol is a chemical chaperone belonging to the polyol family, which increases protein stability and inhibits
protein aggregation. These prompted us to compare the chaperone-like activity of β-casein and glycerol. In this study, the
effect of β-casein and glycerol on folding of the target proteins (ovotransferrin, insulin and α-lactalbumin) in the presence
of dextran, as a macromolecular crowding agent, is examined using visible absorption spectroscopy, intrinsic fluorescence
spectroscopy, 1-anilino-8-naphthalene sulfonic acid fluorescence binding and near CD spectroscopy. In the presence of dextran,
the rate and extent of aggregation of target proteins was enhanced and β-casein was less effective in preventing the aggregation
and precipitation of target proteins. These data support the hypothesis that β-casein interacts more effectively with slowly
aggregating rather than rapidly aggregating target proteins. It is proposed that dextran-induced changes to protein conformation
and the rate of intermolecular association are in a kinetic competition with the chaperoning action of β-casein; however our
results demonstrated the higher activity of glycerol, as a chemical chaperone, than β-casein on the folding of target proteins,
especially in the presence of dextran. This is likely due to the stabilizing effect of glycerol on protein structure and environment.
The implications for the in vivo functions of β-casein and glycerol, based on their exhibiting such in vitro chaperone-like
activities, are discussed. 相似文献

Early growth and differentiation of the pancreatic endoderm is regulated by soluble factors from the pancreatic mesenchyme. Previously, we demonstrated that N-cadherin-deficient mice lack a dorsal pancreas, due to a critical role of N-cadherin in dorsal pancreatic mesenchymal cell survival. Here, we show that restoring cardiac and circulatory function in N-cadherin null mice by cardiac-specific expression of N-cadherin, rescues formation of the dorsal pancreas, indicating that the phenotype is secondary to defects related to cardiac/vascular function. Based on this observation, we demonstrate that soluble factors present in plasma, such as sphingosine-1-phosphate, rescue formation of the dorsal pancreas in N-cadherin-deficient mice. We also show that sphingosine-1-phosphate indirectly promotes budding of the pancreatic endoderm by stimulating pancreatic mesenchymal cell proliferation. Finally, we identify sphingosine-1-phosphate receptors within the mesenchyme and show that pertussis toxin blocks the sphingosine-1-phosphate-induced actions, suggesting the involvement of G-protein-coupled sphingosine-1-phosphate receptors. Thus, we propose a new model where blood vessel-derived sphingosine-1-phosphate stimulates growth and budding of the dorsal pancreatic endoderm by induction of mesenchymal cell proliferation. 相似文献
