Modified mesenchymal stromal cells by in vitro transcribed mRNA: a therapeutic strategy for hepatocellular carcinoma.

Background: Mesenchymal stromal cells (MSCs) tropism for tumours allows their use as carriers of antitumoural factors and in vitro transcribed mRNA (IVT mRNA) is a promising tool for effective transient expression without insertional mutagenesis risk. Granulocyte-macrophage colony-stimulating factor (GM-CSF) is a cytokine with antitumor properties by stimulating the specific immune response. The aim of this work was to generate modified MSCs by IVT mRNA transfection to overexpress GM-CSF and determine their therapeutic effect alone or in combination with doxorubicin (Dox) in a murine model of hepatocellular carcinoma (HCC).

Hepatic SPARC Expression Is Associated with Inflammasome Activation during the Progression of Non-Alcoholic Fatty Liver Disease in Both Mice and Morbidly Obese Patients.

The severity of non-alcoholic fatty liver disease (NAFLD) ranges from simple steatosis to steatohepatitis, and it is not yet clearly understood which patients will progress to liver fibrosis or cirrhosis. SPARC (Secreted Protein Acidic and Rich in Cysteine) has been involved in NAFLD pathogenesis in mice and humans. The aim of this study was to investigate the role of SPARC in inflammasome activation, and to evaluate the relationship between the hepatic expression of inflammasome genes and the biochemical and histological characteristics of NAFLD in obese patients.

Evaluation of cancer stem cells markers expression in HCC trough real-time polymerase chain reaction.

Quantitative real-time polymerase chain reaction (qRT-PCR) flexibility, robustness and reproducibility have rapidly extended the scope of the method. Cancer stem cells are gaining increasing importance since their role in cancer initiation, treatment resistance and recurrence give rise to a wide range of potential diagnostic and therapeutic applications. The expression of several characteristic markers is proven a reliable method to assess stem-like-phenotype of cancer cells.

Design of nalidixic acid‑vanadium complex loaded into chitosan hybrid nanoparticles as smart strategy to inhibit bacterial growth and quorum sensing.

The discovery of new alternatives for the treatment of infectious diseases has become the focus of burgeoning global interest. The complexation of the wide-spectrum antibiotic nalidixic acid (NA) with oxidovanadium(IV) ion and its incorporation into hybrid nanoparticulate systems were explored. The V-NA complex proved to be a stronger antimicrobial agent against E.
