Abstract
Cyano-bridged Gd(3+)/[Fe(CN)6](3-) coordination polymer nanoparticles of 3-4 nm stabilized with D-mannitol presenting a high r1 relaxivity value of 11.4 mM(-1) s(-1) were investigated in vivo as contrast agents (CA) for Magnetic Resonance Imaging (MRI). They allow an increase of the MR image contrast and can act as an efficient intravascular T1 CA with a relatively long blood-circulation lifetime (60 min) without specific toxicity.

Abstract
In this mini-review, we focus on different strategies to bring nanotools specifically to cancer cells. We discuss about a better targeting of tumor, combining the characteristics of tumor environment, the increase in nanoparticles life time, the biomarkers overexpressed on cancer cells and different physical methods for non invasive therapies. Here we detail the necessity of a synergy between passive and active targeting for an actual specificity of cancer cells.

Abstract
Earlier studies indicated that density-arrested cancer cells released an unidentified growth inhibitor whose secretion was prevented by overexpression of the lysosomal protease cathepsin D (cath D). In this study, this growth inhibitor was purified by affinity chromatography and identified as the heat shock cognate 70 protein (hsc70) based on its peptide microsequencing and specific antibody recognition. Among intracellular proteins, including other heat shock proteins, only constitutive hsc70 was secreted in response to the high-cell density. Moreover, hsc70 secretion from cancer cells was generated by serum deprivation, whereas its cellular concentration did not change. Prevention of Hsc70 secretion by cath D overexpression was associated with the formation of multilayer cell cultures, thus indicating a loss of contact inhibition. In addition, we showed that supplementing the culture medium with purified hsc70 inhibited cell proliferation in the nanomolar range. Conversely, removal of this extracellular hsc70 from the medium by either retention on ADP-agarose or competition at the Hsc70 binding site restored cell proliferation. Hsc70 appears active in human breast cancer cells and hypersecreted by direct cath D inhibition. These results suggest a new role of this secreted hsc70 chaperone in cell proliferation that might account for the higher tumor growth of cancer cells overexpressing cath D.

Abstract
The cation-independent mannose 6-phosphate receptor is a multifunctional protein which binds at the cell surface to two distinct classes of ligands, the mannose 6-phosphate (M6P) bearing proteins and IGF-II. Its major function is to bind and transport M6P-enzymes to lysosomes, but it can also modulate the activity of a variety of extracellular M6P-glycoproteins (i.e., latent TGFbeta precursor, urokinase-type plasminogen activator receptor, Granzyme B, growth factors, Herpes virus). The purpose of this review is to highlight the synthesis and potential use of high affinity M6P analogues able to target this receptor. Several M6P analogues with phosphonate, carboxylate or malonate groups display a higher affinity and a stronger stability in human serum than M6P itself. These derivatives could be used to favour the delivery of specific therapeutic compounds to lysosomes, notably in enzyme replacement therapies of lysosomal diseases or in neoplastic drug targeting. In addition, their potential applications in preventing clinical disorders, which are associated with the activities of other M6P-proteins involved in wound healing, cell growth or viral infection, will be discussed.

Abstract
This study investigates the effects of SR141716, a selective CB(1) receptor antagonist that reduces food intake and body weight of rodents, on Acrp30 mRNA expression in adipose tissue. Acrp30, a plasma protein exclusively expressed and secreted by adipose tissue, has been shown to induce free fatty acid oxidation, hyperglycemia and hyperinsulinemia decrease, and body weight reduction. We report that N-(piperidin-1-yl)-5-(4-chlorophenyl)-1-(2,4-dichlorophenyl)-4-methyl-1H-pyrazole-3-carboximide hydrochloride (SR141716) treatment once daily (10 mg/kg/d, i.p.) from 2 to 14 days reduced body weight and stimulated Acrp30 mRNA expression in adipose tissue of obese Zucker (fa/fa) rats. In parallel, the hyperinsulinemia associated with this animal model was reduced by SR141716 treatment. In cultured mouse adipocytes (3T3 F442A), SR141716 (25 to 100 nM) also induced an overexpression of Acrp30 mRNA and protein. In addition, in adipose tissue of CB(1)-receptor knockout mice, SR141716 had no effect on Acrp30 mRNA expression, demonstrating a CB(1) receptor mediating effect. Furthermore, RT-PCR analysis revealed that rat adipose tissue and 3T3 F442A adipocytes expressed CB(1) receptor mRNA. Relative quantification of this expression revealed an up-regulation (3- to 4-fold) of CB(1) receptor mRNA expression in adipose tissue of obese (fa/fa) rats and in differentiated 3T3 F442A adipocytes compared with lean rats and undifferentiated adipocytes, respectively. Western blot analysis revealed the presence of CB(1) receptors in 3T3 F442A adipocytes, and their expression was up-regulated in differentiated cells. These results show that SR141716 stimulated Acrp30 mRNA expression in adipose tissue by an effect on adipocytes, and reduced hyperinsulinemia in obese (fa/fa) rats. These hormonal regulations may participate in the body weight reduction induced by SR141716 and suggest a role of metabolic regulation in the antiobesity effect of SR141716.
