New findings from a Universite de Montreal and the Vaccine and Gene Therapy Institute of Florida (VGTI) study, in collaboration with scientists from the NIH and the McGill University Health Center, may soon lead to an expansion of the drug arsenal used to fight HIV. The Canada-U.S. study published in the journal Nature Medicine characterizes the pivotal role of two molecules, PD-1 and IL-10, in influencing the function of CD4/T-helper cells and altering their ability to fight HIV… (Source: Health News from Medical News Today)

For 25 years, scientists have touted the promise of gene therapy to treat human diseases, but only a handful of therapies have shown progress. Nonetheless, proponents remain optimistic and say the approach may yet revolutionize medicine.» E-Mail This     » Add to Del.icio.us (Source: NPR Health and Science)

In conclusion, intra-ovarian injection of an adenovirus expressing human FSHR gene is able to restore FSH responsiveness and reinitiate ovarian folliculogenesis as well as resume estrogen production in female FORKO mice. Ad-LacZ injections indicate the absence of systemic viral dissemination or germ line transmission of adenovirus DNA to offspring. (Source: Molecular Human Reproduction)

CONCLUSION: VEGF, FLT-1 and FLK-1 are associated with colorectal carcinogenesis. siRNA silencing of the VEGF gene suppresses proliferation, and induces apoptosis in HCT116 cells. The results suggest that VEGF may be a new gene therapy target for colorectal cancer.

The clinical use of gene therapy requires tight regulation of the gene of interest and functional expression only when it is needed. Thus, it is necessary to develop ways of regulating functional gene expression with exogenous stimuli. Many regulatable systems are currently under development. For example, the tetracycline-dependent transcriptional switch has been successfully employed for in vivo preclinical applications. However, there are no examples of regulatable systems that have been employed in human clinical trials. In the present study, we established an adenovirus-delivered functional gene expression system that is regulated by estrogen. This system uses p16INK4A fused at its C-terminus to the ligand-bind…

Stereospecific radiation treatment offers a distinct opportunity for temporal and spatial regulation of gene expression at tumor sites by means of inducible promoters. To this end, a plasmid, pCArG-U2, was constructed by incorporating nine CArG elements (in tandem) of EGR1 gene upstream to uPA and uPAR siRNA oligonucleotides in a pCi-neo vector. Radiation-induced siRNA expression was detected in a meningioma cell line (IOMM-Lee). Immunoblotting and RT-PCR analyses confirmed downregulation of uPA and uPAR. A similar effect was observed in transfected cells followed by H2O2 treatment. Moreover, pre-treatment of transfected cells with N-acetyl L-cysteine blocked the silencing of uPA and uPAR, which fur…

Nonviral gene therapy requires a high yield and a low cost production of eukaryotic expression vectors that meet defined criteria such as biosafety and quality of pharmaceutical grade. To fulfil these objectives, we designed a novel antibiotic-free selection system.The proposed strategy relies on the suppression of a chromosomal amber mutation by a plasmid-borne function. We first introduced a nonsense mutation into the essential Escherichia coli thyA gene, resulting in thymidine auxotrophy. The bacterial strain was optimized for the production of small and novel plasmids free of antibiotic resistance markers (pFARs) and encoding an amber suppressor t-RNA. Finally, the potentiality of pFARs as eukaryotic expression vectors was assessed by monitoring luciferase activities after electrotrans…

Major complications with respect to the development of gene therapy treatments for hemophilia A include low factor VIII (fVIII) expression and humoral immune responses resulting in inhibitory anti-fVIII antibodies. We previously achieved sustained curative fVIII activity levels in hemophilia A mice after nonmyeloablative transplantation of genetically-modified hematopoietic stem cells (HSCs) encoding a B-domain deleted porcine fVIII (BDDpfVIII) transgene with no evidence of an immune response.Mouse HSCs were transduced using MSCV-based recombinant virus encoding BDDpfVIII and transplanted into hemophilia A mice. Transplanted mice were followed for donor cell engraftment, fVIII expression and activity, and generation of anti-fVIII immune response.We now show that: (i) the protein expressed …
