The gene encoding β-catenin is frequently mutated in hepatocellular carcinoma cells. While the oncogenicity of β-catenin has been extensively studied, β-catenin’s role in hepatocellular carcinoma tumor metabolism is currently less well understood.

Glutamine, MTOR and autophagy: a multiconnection relationship
Cancer cells metabolize glutamine mostly through glutaminolysis, a metabolic pathway that activates MTORC1. The AMPK-MTORC1 signaling axis is a key regulator of cell growth and proliferation.

Hepatic endothelial Alk1 signaling protects from development of vascular malformations while maintaining organ‐specific endothelial differentiation and angiocrine portmanteau of the names Wingless and Int‐1 signaling. Abstract Background and Aims In hereditary hemorrhagic telangiectasia (HHT), severe liver vascular malformations are associated with ...

Outgrowth of Rice Tillers Requires Availability of Glutamine in the Basal Portions of Shoots
Background Our previous studies concluded that metabolic disorder in the basal portions of rice shoots caused by a lack of cytosolic glutamine synthetase1;2 (GS1;2) resulted in a severe reduction in the outgrowth of tillers.

Molecular mechanisms of adaptation of the moderately halophilic bacterium Halobacillis halophilus to its environment [PDF]
The capability of osmoadaptation is a prerequisite of organisms that live in an environment with changing salinities. Halobacillus halophilus is a moderately halophilic bacterium that grows between 0.4 and 3 M NaCl by accumulating both chloride and ...

The Rhizobium GstI Protein Reduces the NH4+ Assimilation Capacity of Rhizobium leguminosarum
We show that the protein encoded by the glutamine synthetase translational inhibitor (gstI) gene reduces the NH4+ assimilation capacity of Rhizobium leguminosarum.

Glutamine metabolism in the proliferation of GS-expression pituitary tumor cells
Objective: Many cancer cells cannot survive without exogenous glutamine (Gln); however, cancer cells expressing glutamine synthetase (GS) do not have this restriction.

Asparagine promotes cancer cell proliferation through use as an amino acid exchange factor. [PDF]
Cellular amino acid uptake is critical for mTOR complex 1 (mTORC1) activation and cell proliferation. However, the regulation of amino acid uptake is not well-understood.

The intracellular location of nitrogen metabolism enzymes in Pisum arvense L. roots
The time course changes of nitrate assimilation enzymes and their distribution has been studied in Pisum arvense roots. The results indicate that nitrate reductase (EC 1.6.6.2) and glutamine synthetase (EC 6.3.1.2) are present in the soluble fraction ...

Cancer metabolism at a glance [PDF]
A defining hallmark of cancer is uncontrolled cell proliferation. This is initiated once cells have accumulated alterations in signaling pathways that control metabolism and proliferation, wherein the metabolic alterations provide the energetic and ...
