Disclosed are antagonists designed to inhibit or block expression of a mammalian complement component 9 (C9). The invention has a wide range of uses including use in the preparation of a medicament for the enhancement of nerve regeneration following acute or chronic nerve damage in a mammal.
Abstract:
The present invention relates to nucleic acids and polypeptides encoded thereby, whose expression is modulated in a subject suffering from insufficient arteriogenic capacity. These nucleic acids are among other useful in methods for diagnosing insufficient arteriogenic capacity, treating a subject suffering from insufficient arteriogenic capacity and/or stimulating arteriogenic capacity and/or stimulating arteriogenesis.
Abstract:
The present invention relates to methods for expansion of stem or progenitor cells. These methods rely on Asb-a polypeptides or nucleic acids to temporarily suppress differentiation of the cells, thus allowing proliferation and self-renewal of the stem or progenitor cells. Abs-a polypeptides and coding sequences define a class of polypeptides and nucleic acids that are both structurally and functionally highly conserved among vertebrates. Asb-a polypeptides contain 6 ankyrin repeats and a SOCS box that mediate the effect of the polypeptide on the regulation of specific subsets of genes involved in differentiation. The invention discloses various methods to increase the intracellular concentration of an Asb-a polypeptide for suppression of terminal differentiation of the stem or progenitor cells. The invention further relates to Asb-a polypeptides and nucleic acids, vectors and host cells for use in methods for their production and for use in the method for expansion of stem or progenitor cells, as well as to stem or progenitor cells containing exogenous Asb-a polypeptides and nucleic acids.
Abstract:
The invention relates to the treatment and diagnosis of cancer and to the development of drugs. The invention provides a catalogue of >350 targets of the myc oncogene family. The invention provides the insight that it is the myc oncogene family itself that provides for the recruitment and adaptation of the in essence normal physiological mechanisms and events to support the essentially neoplastic character of a cancer cell. Herewith the invention provides a method for the treatment of cancer comprising modulating a myc-dependent downstream gene. The invention also provides a method to use one or more gene products of myc-downstream genes as readout in screenings assays to identify drugs. The insight provided by the invention that myc boosts the cellular protein synthesis machinery can be used to optimise cellular production systems for recombinant protein synthesis systems.

Abstract:
The invention relates to a method for detecting a pathological defect in a cell by means of an antibody. According to the invention, an antibody is used which is specific for i) a protein of a Polycomb group complex; ii) a corepressor or a coactivator of a Polycomb group complex; or iii) a Boundary element-binding protein. Preferably the extent of binding of the antibody is compared with a reference value determined for a normal cell of that type. An abnormal concentration of a protein, and hence a different reference value, has been found to be a very good indicator for detecting a pathological defect, such as cancer.

Abstract:
A photovoltaic device is provided comprising a thin-film of an energy conversion material. The energy conversion material includes one or more quantum structures, where the quantum structures comprise a semiconductor material having an indirect band-gap in the bulk. The average size of the quantum structures is selected such that a direct and an indirect band-gaps are modified in the semiconductor material such that the direct band-gap provides charge carrier generation when the quantum structures are exposed to light.
