ReviewGlutamine: role in gut protection in critical illness.
Recent literature has focused on the role of the gut and increased gut permeability as a driver of systemic inflammation in critical illness. Thus, the therapeutic potential for an agent to prevent gut barrier compromise and attenuate gut-derived inflammatory response is significant. ⋯ These mechanistic findings, combined with a limited amount of clinical data showing benefit on gut permeability in illness and injury, indicate more formal studies need to be carried out looking the role of glutamine in gut protection and as an antiinflammatory in critical illness.

Review6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase and tumor cell glycolysis.
Neoplastic cells metabolize abundant glucose relative to normal cells in order to satisfy the increased energetic and anabolic needs of the transformed state. This review will summarize the requirement of 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases for the regulation of glycolysis in cancer cells and their potential utility as targets for the development of antineoplastic agents. ⋯ These findings demonstrate a key role for the 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases in neoplastic transformation and provide rationale for the development of agents that selectively inhibit the PFKFB3 enzyme as antineoplastic agents.
