To test this predication, ctf7 single mutant and ctf7 elg1 smc3Q triple mutant cells were transformed either with vector alone or vector providing for elevated PNCA expression.
The whole panel of 104 p53 germline missense mutants from the IARC R11 database (http://p53.iarc.fr) cloned in the pLS-Ad vector (providing for a constitutive expression of p53 mutants) [ 42] were used to test transactivation capability towards the miR-34a p53 RE.
In the absence of transfection, such binding revealed <10 fmol/mg expression in COS-7 cells, while transfection with the whole-gene <span class="lh lhl">vectors provided for ∼1,000 fmol/mg human β2AR expression.
Viral vectors have been demonstrated to be highly effective for gene delivery, and among these, lentiviral vectors provide for efficient gene transfer in cells and mediate stable, high-level transgene expression both in vitro and in vivo [17], [31], [32].
These small vectors provide for long-term transient expression of multiple transgenes without the risks of immunogenic responses as in standard plasmids.
The procedure generated exogenous gene expression in more than 80% of the cells and, to our knowledge, this is one of the first reports of such highly efficient genetic manipulation of EDT-MSC by a single GFP-carrying vector providing a basis for use of these cells in gene therapy approaches, including targeted cancer treatment or their use as cell vectors for peptides or trophic factors.
To date, autochthonous WNV infections have not been reported in Belgium, although the presence of the mosquito vector provides a potential risk for transmission (6 ).
To test whether exogenous HIF-1α over expression can cause a stimulatory effect on DDX3 promoter activity in normoxic conditions, we co-transfected the DDX3 promoter-reporter vector constructs with a vector that provides for constitutive expression of HIF-1α.
Thus, we concluded that the newly constructed mini binary vector provides a more feasible tool for TuMV researches in areas, such as creating a mild strain for cross-protection, or a viral vector for foreign gene expression.
This vector provides ready-to-use T-overhangs for ligation with A-overhangs of PCR-products.
