Provided are compositions and methods for prophylaxis and/or therapy of ErbB2-positive cancer. The compositions include pharmaceutical preparations that contain isolated or recombinant or modified peptidase D (PEPD) proteins. The methods include prophylaxis and/or therapy of ErbB2-positive cancer by administering a PEPD to an individual who has or is at risk for developing ErbB2-positive cancer.

The present invention relates to novel uses of the polypeptides and novel variants of said polypeptides capable of detoxifying Ochratoxin A (OTA) and methods (e.g., for detoxifying mycotoxins) based thereon. The present invention further relates to compositions, kits, transgenic plants, transgenic seeds, transgenic pollen grains, foodstuff, intermediate foodstuff; fodder, intermediate fodder; feed, intermediate feed; additive (e.g., foodstuff-, fodder- or feed additive), intermediate additive (e.g., foodstuff-, fodder- or feed intermediate additive); detoxifying agent, intermediate detoxifying agent; nutritional supplement, intermediate nutritional supplement, prebiotic, intermediate prebiotic and/or mixture/s thereof comprising one or more of the polypeptides and/or variants capable of detoxifying Ochratoxin A (OTA).

Disclosed are methods of making collagen 7, or functional fragments thereof, as well as collagen 7, and functional fragments thereof produced by such methods, nucleic acids encoding collagen 7, and functional fragments thereof, as well as vectors and host cells comprising such nucleic acids.

Provided are methods for treating cancer. The methods involve administering to an individual who has cancer a combination of peptidase D (PEPD), a sheddase inhibitor, a chemotherapeutic agent and a coagulation inhibitor.

Disclosed are methods of making collagen 7, or functional fragments thereof, as well as collagen 7, and functional fragments thereof produced by such methods, nucleic acids encoding collagen 7, and functional fragments thereof, as well as vectors and host cells comprising such nucleic acids.

A method for treating cancer is provided. The method includes administering a combination of a Prolidase, also known as peptidase D (PEPD), in combination with a monoclonal antibody or antigen binding fragment thereof that binds with specificity to a clotting factor, such as Factor XII (FXII). A single dose of the monoclonal antibody is sufficient to enable a therapeutic effect of the PEPD.
