Tumor cell adhesion and migration to laminin are important events during invasion and metastatic spread. Galectin-3, a multifunctional member of the galectin family, binds specifically the poly-N-acetyllactosamine residues of laminin and has been implicated in tumor invasion and metastasis. Galectin-3 is multimerized by transglutaminase, an enzyme that catalyzes cross-linking between glutamine and other aminoacid residues. In this study, we examined the consequences of transglutaminase-mediated galectin-3 oligomerization on the interactions between cancer cells and laminin. We first demonstrated that human galectin-3 is cross-linked by guinea pig liver transglutaminase, forms oligomers, and incorporates the marker 5-(biotinamido) pentylamine. Expression of transglutaminase activity in the A375 and A2058 human melanoma cell extracts was revealed by its ability to induce galectin-3 oligomerization and 5-(biotinamido) pentylamine incorporation. Transglutaminase-treated galectin-3 did not affect adhesion or migration of the melanoma cells to laminin but consistently induced a significant increase of the percentage of cell spreading compared to the control (23.5 +/- 2.3%, vs. 10.6 +/- 1.9% at 180 min, p < 0.05), or to untreated galectin-3 or transglutaminase alone. Our study is the first demonstration that human galectin-3 is oligomerized by transglutaminase with, as a consequence, a specific effect of melanoma cell spreading on laminin. This phenomenon could be of significance in the modulation of cancer cell interactions with laminin during tumor invasion and metastasis. [less ▲]

The principal goal of the study is to equip the small ones and common averages, of the computer tools of which they miss as regards management of the environment, and in particular in the following fields: - the quality of the built medium, public spaces and the landscapes; - the consumption of energy of heating in the public buildings and the management of public lighting; - draining, the cleansing, the management of the cycle of water; - the waste harvest and processing.

Bovine herpesvirus 1 (BHV-1) induces apoptotic cell death in bovine peripheral blood mononuclear cells and B-lymphoma cells. Using a BHV-1 glycoprotein H null mutant, we have demonstrated that although penetration of BHV-1 is not required, attachment of BHV-1 viral particles is essential for the induction of apoptosis.

A mesogenic cation was associated with low molecular weight carboxylato- and sulfonato(se-mi)telechelic polymers. These compounds were prepared by ion-exchange of the quaternary ammonium group attached to the mesogen for the metal counterion of the halato(semi)telechelic polymer. The accordingly formed liquid crystalline halato(semi)telechelic polymers (LC H(S)TP's) were analyzed by differential scanning calorimetry (DSC), polarized-light optical microscopy (POM), and small angle X-ray scattering (SAXS). On the basis of these experimental results, a model for the supramolecular organization of the LC H(S)TP's is proposed. The final morphology results from the interplay of two competitive effects: the dipolar interaction of the ion-pairs known for multiplet formation and the propensity of the mesogenic moiety to form mesophases. The outcome of this competition depends on the mobility of the mesogenic counterion, i.e., on the strength of the dipolar interactions, the mobility of the polymer backbone and the mesogen/poly-mer ratio which is controlled by the molecular weight of the polymer.
