    ABSTRACT: Endothelial dysfunction is decisive and leads to the development of several inflammatory diseases. Endotoxemia-derived sepsis syndrome exhibits a broad inflammation-induced endothelial dysfunction. We reported previously that the endotoxin, lipopolysaccharide (LPS), induces the conversion of endothelial cells (ECs) into activated fibroblasts, showing a myofibroblast-like protein expression profile. Enhanced migration is a hallmark of myofibroblast function. However, the mechanism involved in LPS-induced EC migration is no totally understood. Some studies have shown that the transient receptor potential melastatin 7 (TRPM7) ion channel is involved in fibroblast and tumor cell migration through the regulation of calcium influx. Furthermore, LPS modulates TRPM7 expression. However, whether TRPM7 is involved in LPS-induced EC migration remains unknown. Here, we study the participation of LPS as an inducer of EC migration and study the mechanism underlying evaluating the participation of the TRPM7 ion channel. Our results demonstrate that LPS induced EC migration in a dose-dependent manner. Furthermore, this migratory process was mediated by the TLR-4/NF-κB pathway and the generation of ROS through the PKC-activated NAD(P)H oxidase. In addition, LPS increased the intracellular calcium level and the number of focal adhesion kinase (FAK)-positive focal adhesions in EC. Finally, we demonstrate that using TRPM7 blockers or suppressing TRPM7 expression through siRNA successfully inhibits the calcium influx and the LPS-induced EC migration. These results point out TRPM7 as a new target in the drug design for several inflammatory diseases that impair vascular endothelium function.

    ABSTRACT: Pulmonary hypertension (PH) is characterized by enhanced pulmonary artery smooth muscle cell (PASMC) proliferation leading to vascular remodeling. Although, multiple factors have been associated with pathogenesis of PH the underlying mechanisms are not fully understood. Here, we hypothesize that already very short exposure to hypoxia may activate molecular cascades leading to vascular remodeling. Microarray studies from lung homogenates of mice exposed to only three hours of hypoxia revealed endothelin-1 (ET-1) and connective tissue growth factor (CTGF) as the most upregulated genes, and the mitogen-activated protein kinase (MAPK) pathway as the most differentially regulated pathway. Evaluation of these results in vitro showed that ET-1 but not CTGF stimulation of human PASMCsincreased DNA synthesis and expression of proliferation markers such as Ki67 and cell cycle regulator, cyclin D1. Moreover, ET-1 treatment elevated extracellular signal-regulated kinase (Erk)-dependent c-fos expression and phosphorylation of c-fos and c-jun transcription factors. Silencing of c-fos with siRNA abrogated the ET-1-induced proliferation of PASMCs. Expression and immunohistochemical analyses revealed higher levels of total and phosphorylated c-fos and c-jun in the vessel wall of lung samples of human idiopathic pulmonary arterial hypertension patents, hypoxia-exposed mice and monocrotaline-treated rats as compared to control subjects. These findings shed the light on the involvement of c-fos/c-jun in the proliferative response of PASMCs to ET-1 indicating that already very short hypoxia exposure leads to the regulation of mediators involved in vascular remodeling underlying PH.

    ABSTRACT: Efforts in understanding the role of the microenvironment in the development of breast cancer have focused on tumor-stroma cross-talk, but the possibility that normal epithelial cells might also play a role in tumor progression has received little attention. Here, we show that non-tumorigenic human mammary epithelial cells (MCF10A and HMEC) secrete factors able to enhance the proliferation of estrogen receptor α (ERα) positive breast cancer cells (MCF7 and T47D) and suppress their ability to undergo apoptosis. Conditioned medium (CM) derived from MCF10A and HMEC cells was capable of activating ERα in a hormone-independent way, by phosphorylating ERα on Ser167. Co-exposure with PI3K and mTORC1 inhibitors significantly reduced the ERα Ser167 phosphorylation and suppressed the proliferation-enhancing effects of both 10A-CM and HMEC-CM on MCF7 cells. We show that MCF10A and HMEC secrete numerous cytokines, among them MCP-1, which was one of the most prevalent. MCP-1 was shown to have a role in the effects elicited by the 10A-CM. It activated the ERα by phosphorylating Ser167 via the PI3K/Akt/mTORC1 signaling pathway, an effect which was further confirmed by silencing the MCP-1 receptors, CCR2 and CCR4. To our knowledge, this is the first time MCP-1 has been shown to contribute to ERα signaling activation. These data suggest that normal mammary cells could have the capability of supporting the proliferation of breast cancer cells via paracrine interactions. A better understanding of the role of these cells may be useful for designing strategies for the prevention of tumor progression at early stages.A

    ABSTRACT: Gangliosides play important roles in the development, differentiation and proliferation of mammalian cells. They bind to other cell membrane components through their terminal sialic acids. Different gangliosides influence cellular functions based on the positions and linkages of sialic acids. Expression of gangliosides mainly depends on the status of sialic acid-modulatory enzymes, such as different types of sialyltransferases and sialidases. One such sialyltransferase, disialoganglioside GD3 synthase, is specifically responsible for the production of GD3. Pancreatic ductal adenocarcinoma, making up more than 90% of pancreatic cancers, is a fatal malignancy with poor prognosis. Despite higher sialylation status, the disialoganglioside GD3 level is very low in this cancer. However, the exact status and function of this disialoganglioside is still unknown. Here, we intended to study the intracellular mechanism of disialoganglioside GD3-induced apoptosis and its correlation with the adhesion and angiogenic pathways in pancreatic cancer. We demonstrated that disialoganglioside GD3 synthase-transfected cells showed enhanced apoptosis and it caused the arrest of these cells in the S-phase of the cell cycle. Integrins, a family of transmembrane proteins play important role in cell–cell recognition, invasion, adhesion and migration. disialoganglioside GD3 co-localised with integrin-β1 and thereby inhibited it's downstream signalling in transfected cells. Transfected cells exhibited inhibition of cell adhesion with extracellular matrix proteins. Enhanced GD3 expression down regulated angiogenesis-regulatory proteins and inhibited epidermal growth factor/vascular endothelial growth factor-driven angiogenic cell growth in these cells. Taken together, our study provides support for the GD3-induced cell cycle arrest, disruption of integrin-β1-mediated anchorage, inhibition of angiogenesis and thereby induced apoptosis in pancreatic cancer cells.

    ABSTRACT: Rhodopsin was the first G protein-coupled receptor (GPCR) for which a high-resolution crystal structure was obtained. Several crystal structures have now been solved representing different activation states of the receptor. These structures, together with those from lower resolution techniques (e.g. electron microscopy), shed light on the stepwise process by which energy from an extracellular photon is transduced across the membrane to the intracellular compartment thereby activating signalling mechanisms responsible for very low-level light detection. Controversy remains in several areas including: (i) transmembrane helix movements responsible for the transduction process, (ii) the stoichiometry of coupling to G proteins and their mode of activation, (iii) the role, if any, of receptor oligomerisation and (iv) the suitability of using structures of this GPCR as templates for modelling the structures of other GPCRs, and their mechanisms of activation.

    ABSTRACT: The theory of Darwinian evolution is the fundamental keystones of modern biology. Late in the last century, computer scientists began adapting its principles, in particular natural selection, to complex computational challenges, leading to the emergence of evolutionary algorithms. The conceptual model of selective pressure and recombination in evolutionary algorithms allow scientists to efficiently search high dimensional space for solutions to complex problems. In the last decade, genetic programming has been developed and extensively applied for analysis of molecular data to classify cancer subtypes and characterize the mechanisms of cancer pathogenesis and development. This article reviews current successes using genetic programming and discusses its potential impact in cancer research and treatment in the near future.
