Targeting Glutamine Metabolism for Cancer Treatment
Rapidly proliferating cancer cells require energy and cellular building blocks for their growth and ability to maintain redox balance. Many studies have focused on understanding how cancer cells adapt their nutrient metabolism to meet the high demand of anabolism required for proliferation and maintaining redox balance. Glutamine, the most abundant amino acid in plasma, is a well-known nutrient...
متن کاملTargeting glutamine metabolism rescues mice from late-stage cerebral malaria.
The most deadly complication of Plasmodium falciparum infection is cerebral malaria (CM) with a case fatality rate of 15-25% in African children despite effective antimalarial chemotherapy. There are no adjunctive treatments for CM, so there is an urgent need to identify new targets for therapy. Here we show that the glutamine analog 6-diazo-5-oxo-L-norleucine (DON) rescues mice from CM when ad...
متن کاملTargeting Glutamine Metabolism in Breast Cancer with Aminooxyacetate.
PURPOSE Glutamine addiction in c-MYC-overexpressing breast cancer is targeted by the aminotransferase inhibitor, aminooxyacetate (AOA). However, the mechanism of ensuing cell death remains unresolved. EXPERIMENTAL DESIGN A correlation between glutamine dependence for growth and c-MYC expression was studied in breast cancer cell lines. The cytotoxic effects of AOA, its correlation with high c-...
متن کاملRB in glutamine metabolism
In a majority of cancer cells, inactivation of the retinoblastoma protein (pRB) through hyperphosphorylation, deletion, or mutation leads to dissociation from E2F effector proteins and aberrant activation of downstream target genes. Suppression of pRB function ultimately results in the loss of regulatory control over multiple biochemical pathways required for tumorigenesis, including cell cycle...
متن کاملAvian mitochondrial glutamine metabolism.
Intact avian liver mitochondria were shown to synthesize glutamine from glutamate in the absence of exogenous ATP and ammonia. With L-[U-14C]glutamate as the substrate, there was an approximate 1:1 stoichiometry between glutamate deaminated (as measured by the release of 14CO2 due to alpha-keto-[14C]glutarate oxidation) and glutamate amidated. With L-[15N]glutamate as the substrate, the isolate...
