Molecules, Vol. 27, Pages 2082: Inhibition of Metastatic Hepatocarcinoma by Combined Chemotherapy with Silencing VEGF/VEGFR2 Genes through a GalNAc-Modified Integrated Therapeutic System
Jing Hu Hepatocellular carcinoma (HCC) is a highly malignant tumor related to high mortality and is still lacking a satisfactory cure. Tumor metastasis is currently a major challenge of cancer treatment, which is highly related to angiogenesis. The vascular endothelial growth factor (VEGF)/VEGFR signaling pathway is thus becoming an attractive therapeutic target. Moreover, chemotherapy combined with gene therapy shows great synergistic potential in cancer treatment with the promise of nanomaterials. In this work, a formulation containing 5-FU and siRNA against the VEGF/VEGFR signaling pathway into N-acetyl-galactosam...

Preparation and Characterization of a Liver Targeted, Poly(amidoamine) Based, Gene Delivery System
Methods Mol Biol. 2022;2455:319-332. doi: 10.1007/978-1-0716-2128-8_24.ABSTRACTNonalcoholic steatohepatitis (NASH) is an aggressive liver disease that is considered a major cause of liver cirrhosis and hepatocellular carcinoma. NASH is characterized by multiple underlying genetic mutations, with no approved cure to date. Gene therapies that target those genetic mutations may play a major role in treating this disease, once delivered specifically to the hepatocytes. In this chapter we present, in detail, the synthesis and the characterization of an efficient gene delivery system capable of targeting hepatocytes by exploitin...

Glycyrrhetinic acid-modified graphene oxide mediated siRNA delivery for enhanced liver-cancer targeting therapy.
Abstract Graphene oxide (GO) has attracted huge attention in biomedical field in recent years. However, limited attempts have been invested in utilizing GO on active targeted delivery for gene therapy in liver cancer treatments. Glycyrrhetinic acid (GA) has been reported to be widely used as a targeting ligand to functionalize nanomaterials to treat hepatocellular carcinoma. In this article, GA is employed as a liver targeting ligand to construct GA, polyethylene glycol (PEG), polyamidoamine dendrimer (Dendrimer) and nano-graphene oxide (NGO) conjugate (GA-PEG-NGO-Dendrimer, GPND) for siRNA delivery for the first ...

Lentivirus-mediated RNA interference targeting EBNA1 gene inhibits the growth of GT-38 cells in vitro and in vivo.
Authors: Wang J, Liang C, Meng F, Xu X, Wu Y, Lu L Abstract Epstein-Barr virus nuclear antigen 1 (EBNA1) is associated with the pathogenesis of Epstein-Barr virus-associated gastric carcinoma (EBVaGC). However, the function of EBNA1 in the growth of EBVaGC cells remains unclear. In the present study, the effects of silencing EBNA1, by RNA interference (RNAi), on the growth of EBVaGC cells were investigated in vitro and in vivo. A lentivirus-mediated RNAi targeting EBNA1 was transfected into the EBVaGC cell line GT-38. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR), western blot analysis, MTT...

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

SOCS and Herpesviruses, With Emphasis on Cytomegalovirus Retinitis
Christine I. Alston1,2 and Richard D. Dix1,2* 1Department of Biology, Viral Immunology Center, Georgia State University, Atlanta, GA, United States 2Department of Ophthalmology, Emory University School of Medicine, Atlanta, GA, United States Suppressor of cytokine signaling (SOCS) proteins provide selective negative feedback to prevent pathogeneses caused by overstimulation of the immune system. Of the eight known SOCS proteins, SOCS1 and SOCS3 are the best studied, and systemic deletion of either gene causes early lethality in mice. Many viruses, including herpesviruses such as herpes simplex virus and cytomega...

Hydroxyl-Rich PGMA-Based Cationic Glycopolymers for Intracellular siRNA Delivery: Biocompatibility and Effect of Sugar Decoration Degree.
Abstract The ErbB family of proteins, structurally related to the epidermal growth factor receptor (EGFR), is found to be over-expressed in many cancers such as gliomas, lung and cervical carcinomas. Gene therapy allows to modify the expression of genes like ErbB and has been a promising strategy to target oncogenes and tumor suppressor genes. In the current work, novel hydroxyl-rich polyglycidyl methacrylate (PGMA)-based cationic glycopolymers were designed for intracellular small interfering RNA (siRNA) delivery to silence the EGFR gene. The cationic polymers with different sugar decoration degrees (0%, 9%, and ...

Application of cationized magnetoferritin for magnetic field-assisted delivery of short interfering RNA in vitro
AbstractCationized magnetoferritin is used for development of a simple, efficient, and fast delivery of short interference RNA into cells using combination of magnetophoresis for pre-concentration of siRNA-magnetoferritin complex on the surface of plated cells with subsequent application of nanosecond laser pulses producing stress waves in transfection chamber, which permeabilize cell membrane for the facilitated delivery of siRNA into the cell interior. As has been quantified using siRNA inducing cell death assay, by combination of these two physical factors we have obtained high efficiency for tested three different huma...

Interfering RNA with multi-targets for efficient gene suppression in HCC cells.
Abstract RNA interference (RNAi) technology has been widely used in therapeutics development, especially multiple targeted RNAi strategy, which is a better method for multiple gene suppression. In the study, interfering RNAs (iRNAs) were designed for carrying two or three different siRNA sequences in different secondary structure formats (loop or cloverleaf). By using these types of iRNAs, co-inhibition of survivin and B-cell lymphoma-2 (Bcl-2) was investigated in hepatocellular carcinoma (HCC) cells, and we obtained promising gene silencing effects without showing undesirable interferon response. Furthermore, su...

Anti-apoptosis Effect of Decoy Receptor 3 in Cholangiocarcinoma Cell Line TFK-1.
CONCLUSIONS: The effect of DcR3 on the growth and apoptosis of cholangiocarcinoma has been demonstrated. DcR3 is not only a predictive marker for malignant tumor but it is also likely to be a potential target for cancer gene therapy. Further studies should focus on exploring the binding ligand of DcR3, the signaling pathway involved, and the molecular mechanism for the regulation of DcR3 expression in cholangiocarcinoma.
