Antiangiogenic Gene Therapy in Cancer.

Antiangiogenic Gene Therapy in Cancer. Curr Genomics. 2000;1(2):117-133 Authors: Zhang L, Chen QR, Mixson AJ Abstract One of the most recent and exciting approaches in cancer gene therapy is the ability to target the developing blood supply of the tumor. An appealing feature of antiangiogenic gene therapy is that the tumor vasculature is a readily accessible target, particularly when the carrier and its gene are administered systemically. This is in contrast to several other gene therapy approaches in which the tumor vasculature represents a major obstacle to achieving high levels of transfection of the tumor cells. Several gene-based viral or non-viral therapies that target tumor angiogenesis have shown efficacy in pre-clinical models. Genes that encode antiangiogenic polypeptides such as angiostatin and endostatin have significantly inhibited tumor growth, inducing a microscopic dormant state. The products of these genes are thought to act extracellularly to inhibit angiogenesis. An alternative approach that investigators have used successfully in tumor-bearing mice is to target angiogenic growth factors or their receptors that are essential for tumor growth. Levels of angiogenic factors such as vascular endothelial growth factor (VEGF) have been reduced by either antisense methods or the use of genes encoding truncated angiogenic decoy receptors. Despite these promising findings of tumor reduction with antiangiogenic gene therapy, advances in the viral...

A Chicago biotech claims in a new lawsuit that Cambridge venture capital firm Third Rock Ventures and bluebird bio CEO Nick Leschly worked to hinder its drug development efforts so it could more easily obtain a key part of its intellectual property. Errant Gene Therapeutics is suing Third Rock Ventures and Leschly three years after it sued New York-based Sloan Kettering Memorial Cancer Center over a stalled rare disease trial. In the lawsuit, filed on Friday in Suffolk County Superior Court, Errant…

This study aimed at clarifying the mechanism and role of survivin in hypoxia-induced multidrug resistance (MDR) of laryngeal carcinoma cells. Human laryngeal cancer cells were incubated under hypoxia or normoxia. The expression of survivin was silenced by performing RNA interference. Additionally, by Western blot and real-time quantitative RT-PCR, survivin expression was detected. The sensitivity of human laryngeal carcinoma cells to multiple drugs was measured by CCK-8 assay. Meanwhile, the apoptosis of cells induced by cisplatin or paclitaxel was assessed by Annexin-V/propidium iodide staining analysis. Under hypoxic con...

In this study, we have successfully formulated oxaliplatin (OXL) and miRNA-204-5p loaded polyethyleneimine (PEI)/hyaluronic acid (HA)-assembled mesoporous silica nanoparticles (OXmi-HSMN). Our study, for the first time, proved that miRNA-204-5p can generate a synergistic anticancer effect with OXL with HMSN, and thus improve the effects of therapeutic efficacy in colon cancers. In vitro targeting studies showed that OXmi-HSMN exhibited higher uptake efficiency in CD44 receptor over-expressed HT-29 cells via CD44 receptor-mediated endocytosis. OXmi-HMSN exhibited a higher cell cytotoxicity compared to any other formulations...

Abstract Photodynamic therapy (PDT) was considered as an effective treatment. Whereas only PDT is not enough to achieve effective therapy on account of irradiation intensity decreases as depth increases as well as tumor hypoxia. Combination with gene therapy and photodynamic therapy have emerged as an effective strategy to improve therapeutic effectiveness. In the present study, a GSH responsive MnO2 was employed to delivery TB and DNAzyme for cancer imaging and PDT-gene combination treatment. TB, a photosensiters with aggregation-induced emission characteristic, was employed for photodynamic therapy, while DNAzym...
