Disclosed herein are compositions and methods that involve using compositions containing one or more of ETV2, FOXC2, FLI1 and a miR-200b inhibitor for directly reprogramming somatic cells into induced vasculogenic cells both in vitro and in vivo. These compositions and methods are useful for a variety of purposes, including the development of pro-angiogenic therapies.

This invention provides synthetic promoters capable of promoting and/or initiating transcription of a polynucleotide in an algal cell, and methods of designing, producing and using such promoters.

The present invention provides an isolated nucleic acid molecule comprising, or consisting of, the nucleic acid sequence of SEQ ID NO:1 or a nucleic acid sequence of at least 400 bp having at least 80% identity to said sequence of SEQ ID NO:1, wherein said isolated nucleic acid molecule specifically leads to the expression in rod photoreceptors of a gene when operatively linked to a nucleic acid sequence coding for said gene.

Methods and compositions relating to the engineering of an improved protein with methionine-γ-lyase enzyme activity are described. For example, in certain aspects there may be disclosed a modified cystathionine-γ-lyase (CGL) comprising one or more amino acid substitutions and capable of degrading methionine. Furthermore, certain aspects of the invention provide compositions and methods for the treatment of cancer with methionine depletion using the disclosed proteins or nucleic acids.

Anti-angiogenic gene therapy with a combination of soluble Vascular Endothelial Growth Factors (sVEGFR) improves the efficacy of chemotherapy with paclitaxel for reducing ovarian cancer mean tumor volume (in cubic millimetres) as measured using magnetic resonance imaging. The study groups were: AdLacZ control, combination of AdsVEGFR-1, -2 and -3, combination of AdsVEGFR-1, -2, -3 and paclitaxel, bevacizumab monotherapy, paclitaxel monotherapy and carboplatin monotherapy. Effectiveness was assessed by survival time and surrogate measures such as sequential MRI, immunohistochemistry, microvessel density and tumor growth. Antiangiogenic gene therapy combined with paclitaxel significantly prolonged the mean survival compared to the controls and all other treatment groups (p=0.001). Tumors of the mice treated by gene therapy were significantly smaller than in the control group (p=0.021). The mean vascular density and total vascular area were also significantly smaller in the tumors of the gene therapy group (p=0.01).
