  • Publication number: 20140068794
    Abstract: The present invention stems from the finding that two genes designated R2R1 and R2R2, play important roles in tissue development and cancer biology. In particular, the inventors have discovered that these two genes are expressed in pulmonary cells and are required for late branching morphogenesis of pulmonary epithelium and endothelium and support the development/maintenance of the refined three dimensional architecture of the lung. These genes are essential in the squamous differentiation program and development/maintenance of the progenitor (Krt14 expressing) cell pool. Moreover, the inventors have identified crucial roles for these genes in cancer biology, particularly processes associated with the acquisition of an immortal and metastatic phenotype (including cancer progression and metastasis) and pulmonary and cardiac development. Accordingly, the invention provides compounds and methods for use in the treatment of cardiac and pulmonary diseases and well as in cancer.

  • Patent number: 8361979
    Abstract: In the present invention means and method are provided for optimising exon-skipping using exon-internal AON. We show that skipping efficiencies are improved by targeting putative splicing regulatory sequences (ESEs) within an exon. Such double targeting may be particularly useful for exons with which efficient skipping was difficult to obtain prior to the invention.

  • Publication number: 20120315304
    Abstract: The metabolization of certain phenols, monophenols or benzenediols into reactive quinone compounds, in particular ortho-quinones and related reactive intermediates, which is brought about by oxidation of monophenols and benzenediols by proteins exhibiting tyrosinase activity, such as human tyrosinase and the related proteins TRP1 and TRP2. The compounds function as haptens that become covalently bound to the tyrosinase enzymes, in particular to histidine moieties, in or near the catalytic site of proteins exhibiting tyrosinase activity, such as tyrosinase, TRP1 and TRP2. An immune response is then to be mounted against these haptenized auto-antigens to treat malignancies.

  • Patent number: 8304398
    Abstract: The present invention provides means and methods for alleviating genetic disease. A genetic defect that has a phenotype in differentiated cells can lead to defects in precursor cells thereof. These so-called secondary defects contribute to the overall disease of the individual. In the present invention, genetic intervention with the aim to alleviate symptoms of genetic disease is directed toward the primary genetic defect in the differentiated cell and the secondary defect in the precursor cell.
