Osteogenic commitment and differentiation of human mesenchymal stem cells by low‐intensity pulsed ultrasound stimulation

2018

Low-intensity pulsed ultrasound (LIPUS) as an adjuvant therapy in in vitro and in vivo bone engineering has proven to be extremely useful. The present study aimed at investigating the effect of 30 mW/cm(2) LIPUS stimulation on commercially available human mesenchymal stem cells (hMSCs) cultured in basal or osteogenic medium at different experimental time points (7d, 14d, 21d). The hypothesis was that LIPUS would improve the osteogenic differentiation of hMSC and guarantying the maintenance of osteogenic committed fraction, as demonstrated by cell vitality and proteomic analysis. LIPUS stimulation (a) regulated the balance between osteoblast commitment and differentiation by specific network…

Myc Promoter-Binding Protein-1 (MBP-1) Is a Novel Potential Prognostic Marker in Invasive Ductal Breast Carcinoma

2010

BackgroundAlpha-enolase is a glycolytic enzyme that catalyses the formation of phosphoenolpyruvate in the cell cytoplasm. α-Enolase and the predominantly nuclear Myc promoter-binding protein-1 (MBP-1) originate from a single gene through the alternative use of translational starting sites. MBP-1 binds to the P2 c-myc promoter and competes with TATA-box binding protein (TBP) to suppress gene transcription. Although several studies have shown an antiproliferative effect of MBP-1 overexpression on several human cancer cells, to date detailed observations of α-enolase and MBP-1 relative expression in primary tumors versus normal tissues and their correlation with clinicopathological features ha…

Rôle de la Dynamique Membranaire dans la Mise en Place des Mécanismes de Défense chez le Tabac

2011

Cryptogein, a protein secreted by the oomycete Phytophthora cryptogea, induces defense mechanisms in tobacco. Several proteins involved in the associated signaling pathway were identified and localized on the plasma membrane (PM). A fraction resistant to solubilization by detergent named DIMs for Detergent Insoluble Membranes, enriched in sterols an sphigolipids had been isolated from tobacco PM. It was proved to contain proteins previously identified as actors of the signaling cascade triggered by cryptogein. In animal cells, the dynamic association of proteins to sterol and sphingolipid rich microdomains under the influence of a biological stimulus plays an essential role in the regulatio…

Label-free quantitative proteomic profiling of colon cancer cells identifies acetyl-CoA carboxylase alpha as antitumor target of Citrus limon-derived…

2017

Abstract We have previously isolated exosome-like nanoparticles from Citrus-limon juice, able to inhibit in vitro and in vivo tumor cell growth. In order to deeply understand the mechanism underlying nanovesicle effects, we performed a proteomic profile of treated colorectal cancer cells. Among the proteins differentially expressed after nanovesicle treatment, we found a significant downregulation of the Acetyl-CoA Carboxylase 1 (ACACA) and we demonstrated that silencing ACACA in cancer cells leads to a reduction of cell growth. Our study proved that the anti-tumor effects of Citrus-limon nanovesicles is partly mediated by lipid metabolism inhibition, in particular via ACACA downregulation.…

EVpedia: a community web portal for extracellular vesicles research

2014

Abstract Motivation: Extracellular vesicles (EVs) are spherical bilayered proteolipids, harboring various bioactive molecules. Due to the complexity of the vesicular nomenclatures and components, online searches for EV-related publications and vesicular components are currently challenging. Results: We present an improved version of EVpedia, a public database for EVs research. This community web portal contains a database of publications and vesicular components, identification of orthologous vesicular components, bioinformatic tools and a personalized function. EVpedia includes 6879 publications, 172 080 vesicular components from 263 high-throughput datasets, and has been accessed more tha…

DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY

2015

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…

The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin belongs to the family of small leucine-rich proteoglycans (SLRP) and is involved physiologically in the fibrillogenesis of collagen. In the last few year a new anti-oncogenic role has been proposed for decorin1. This study aimed to implement the knowledge on the effects of ectopic decorin on breast cancer cells using as a reference point the results already achieved by our research group2 on the experimental model format. By breast cancer cell line 8701-BC and its transfected clone DEC-C2. The extension of the proteomic analysis combined with the mass spectrometry allowed to triplicate the number of identified proteins in our model. Among the newly identified proteins were members of the classes of metabolic enzymes S100 family and cell motility proteins which revealed a net decrease in the decorin transfected cells. Of considerable importance is the observation that these classes of proteins are the most involved in metastatic progression. These results confirm and reinforce the anti-oncogenic role hypothesized for decorin. The work was co-funded by the Italian 5x1000 to COBS.DECORIN
