  • Patent number: 9950029
    Abstract: The present invention provides a method of treating BPH using modified pore-forming proteins (MPPs). These MPPs are derived from naturally occurring cytotoxic proteins (nPPs) that kill cells by forming pores or channels in the cell membrane, resulting in cell death. The MPPs are generated by modification of the nPPs such that they are capable of being selectively activated at normal prostate cells. Such modification may include the addition of a prostate-specific protease cleavage site to the activation sequence, and/or the addition of a prostate-specific targeting domain to allow selective targeting of prostate cells. These MPPs are capable of selectively targeting and killing normal prostate cells in vivo. The MPPs may be used either alone or in combination with other therapies for the treatment of BPH.

  • Patent number: 7838266
    Abstract: Disclosed herein are modified proaerolysin (PA) peptide. In some examples, the proteins include a prostate-specific protease cleavage site and can further include a prostate-tissue-specific binding domain which functionally replaces the native PA binding domain. In other examples, the proteins include a furin cleavage site and a prostate tissue-specific binding domain which functionally replaces the native PA binding domain. Methods of using such peptides to treat prostate cancer are also disclosed.

  • Publication number: 20090016988
    Abstract: The present invention provides modified pore-forming protein toxins (MPPTs), capable of being used to kill cancer cells. The MPPTs according to the present invention comprise a modification of the naturally occurring activation sequence comprising one or more general cleavage sites, each of which is cleavable by general activating agent, or a plurality of specific cleavage sites, each of which is cleavable by a specific activating agent. Optional further modifications that allow specific targeting of these molecules are also described. These MPPTs may be used to treat cancer.

  • Patent number: 6593095
    Abstract: The present invention relates to toxins that specifically bind to GPI anchored proteins. More specifically, the present invention encompasses the uses of such toxins to detect the presence or absence of GPI anchored proteins. In one embodiment the present invention can be used to detect the presence of paroxysmal nocturnal hemoglobinuria.
