  • Publication number: 20220087981
    Abstract: The present invention relates to active agents or compounds as well as pharmaceutical compositions comprising said compounds, which are capable of reducing or inhibiting or blocking the enzymatic activity of the glutaminyl-peptide cyclotransferase (QPCT) protein, the glutaminyl-peptide cyclotransferase-like protein (QPCTL) protein, or combinations thereof or are capable of reducing or inhibiting the expression of QPCT gene, the QPCTL gene, or combinations thereof. Also provided are methods for screening or selecting for said compounds. The present invention further relates to a pharmaceutical composition comprising a first active agent for use in a method of treating a condition in a subject that would benefit from reducing the signaling or the binding between SIRP? and CD47 in the subject (e.g. cancer), wherein the method of treating comprises reducing expression or enzymatic activity of QPCTL, QPCT, or combinations thereof in the cell with CD47 on the surface.

  • Publication number: 20190309287
    Abstract: The present invention comprises generally applicable methods for identifying endogenous physiologically relevant genetic elements that affects a intracellular phenotype of interest. In the methods, non-living cells that have been subjected to a mutagenesis treatment are sorted based on phenotype and analyzed to identify the genetic element. By use of these methods, elements previously unknown to be involved in a phenotype can be identified, for example in relationship to health conditions, external stress or drug response, in particular in cancer.

  • Patent number: 9234885
    Abstract: Methods and assays for treating a subject with a filovirus infection using an agent that inhibits Niemann-Pick CI (NPCI), VPSII, VPSI6, VPSI8, VPS33A, VPS39, VPS41, BLOCISI, BLOCIS2, GNPTAB, PIKFYVE, ARHGAP23 or FIG4. Methods for screening for an agent that treats and/or prevents infection of a subject with a filovirus, where the methods comprise determining whether the agent inhibits one or more of Niemann-Pick CI (NPCI), VPSII, VPSI6, VPSI8, VPS33A, VPS39, VPS41. BLOCISI, BLOCIS2, GNPTAB, PIKFYVE, ARHGAP23 or FIG4, wherein an agent that inhibits one or more of NPCI, VPSII, VPSI6, VPSI8, VPS33A, VPS39, VPS41, BLOCISI, BLOCIS2, GNPTAB, PIKFYVE, ARHGAP23 or FIG4 is a candidate for treating and/or preventing an infection with a filovirus and wherein an agent that does not inhibit NPCI, VPSII, VPSI6, VPSI8, VPS33A. VPS39, VPS41, BLOCISI, BLOCIS2, GNPTAB, PIKFYVE, ARHGAP23 or FIG4 is not a candidate for treating and/or preventing an infection with a filovirus.
