Disclosed herein are synergistically effective combinations of Amino Acid Depletion Agents (AADA) and Amino Acid Depletion Agent Sensitizers (AADAS). Also disclosed are methods of using the disclosed combinations to treat subjects with a disease treatable by amino acid depletion-induced cell death (e.g. apoptosis). For example, the disclosed combinations are useful in the treatment or the manufacture of a medicament for use in the treatment of adult and pediatric cancers, in particular, acute lymphoblastic leukemia (ALL), as well as other conditions where amino acid depletion-induced apoptosis is expected to have a therapeutically useful effect. The synergistic combinations are also effective against solid tumors and lymphomas, including gastric cancer, pancreatic cancer, NK lymphoma, DLBCL, colorectal cancer, bladder cancer, hepatic cancer and glioblastoma.

Methods for making hemoglobin based blood substitute preparations and hemoglobin based blood substitute preparations. The methods involve preparing a low purity erythrocyte protein fraction comprising hemoglobin protein and endogenous non-hemoglobin protein complement, and chemically modifying the proteins in the protein fraction to form a cross-linked hemoglobin containing blood substitute preparation. The low purity erythrocyte protein preparation can contain from at least about 0.2% (mole/mole) up to about 20% (mole/mole) endogenous non-hemoglobin protein complement. At least about 90% (mole/mole) of the hemoglobin proteins can be cross-linked, so that the average molecular mass of cross-linked proteins comprising hemoglobin protein molecules in the preparation is at least about 300 kDa. The preparations can be used to prepare finished blood substitute formulations for in-vivo and ex-vivo use.

A method of making an erythroid cell comprising elevated levels of a target protein or polypeptide, the method comprising: a) provision of an erythroid progenitor which is able to express the target protein or polypeptide; b) expression of the target protein or polypeptide; and c) maturation of the erythroid progenitor into the erythroid cell; wherein during maturation of the erythroid progenitor into the erythroid cell, the target protein or polypeptide is configured and/or inhibited such that ubiquitination of the target protein or polypeptide is hindered or prevented. Erythroid cells, pharmaceutical compositions and methods of use related thereto, and a method of screening for proteins or polypeptides degraded by ubiquitination during maturation of an erythroid progenitor are also provided.
