The present invention relates to the field of cancer. More specifically, the present invention provides compositions and methods for treating cancer using albumin-proaerolysin prodrugs. Accordingly, in one aspect, the present invention provides prodrug compositions. In certain embodiments, a prodrug composition comprises a prostate-specific antigen (PSA)-activated pro-aerolysin (PA), wherein a PSA cleavable linker replaces the native furin cleavage site within PA; and human serum albumin (HSA) or a fragment thereof fused to the N-terminus of the PSA-activated PA.

Provided herein are compositions and methods to make and use engineered cells, for the purpose of increasing the cell density of a culture comprising metazoan cells and for the production of a cultured edible product.

Non-human animal genomes, non-human animal cells, and non-human animals comprising a humanized albumin (ALB) locus and methods of making and using such non-human animal genomes, non-human animal cells, and non-human animals are provided. Non-human animal cells or non-human animals comprising a humanized albumin locus express a human albumin protein or a chimeric albumin protein, fragments of which are from human albumin. Methods are provided for using such non-human animals comprising a humanized albumin locus to assess in vivo efficacy of human-albumin-targeting reagents such as nuclease agents designed to target human albumin.

Provided herein are compositions and methods to make and use engineered cells, for the purpose of increasing the cell density of a culture comprising metazoan cells and for the production of a cultured edible product.

Protein based highly stretchable compositions with ionic conductivity are disclosed herein. Methods for preparing such compositions are also disclosed.

Disclosed herein are reduced viscosity liquid formulations comprising a protein and an excipient compounds. Further disclosed are methods of reducing the viscosity of a liquid formulation comprising a protein, methods of treatment, and methods of improving protein processing.

The present invention relates to fusion proteins suitable for use as a medicament or research tool. Therapeutic uses of the fusion proteins may include the prevention or treatment of acute or chronic inflammatory and immune system-driven organ and micro-vascular disorders, for example, acute kidney injury, acute myocardial infarction, acute respiratory distress or chronic obstructive pulmonary disease fibrosis and other organ injuries resulting from tissue trauma and acute and chronic injury.
