Targeting the glutamatergic system for the treatment of HIV-associated neurocognitive disorders.
Review
New
Slusher et al., Baltimore, United States. In J Neuroimmune Pharmacol, Jun 2013
One alternative to direct receptor blockade has been the inhibition of enzymes responsible for the production of glutamate such as glutaminase and glutamate carboxypeptidase II.
Effect of different maternal metabolic characteristics on fetal growth in women with gestational diabetes mellitus.
New
Jamal et al., Tehrān, Iran. In Iran J Reprod Med, Apr 2013
After adjustment for confounding variables, maternal hypertriglyceridemia remained as a significant risk factor for delivering large for gestational age (LGA) newborns (p=0.04); and according to spearman test the increase of TG level was correlated with increase of insulin resistance and HOMA-IR (p<0.001,

Targeting cellular metabolism to improve cancer therapeutics.
Review
Tan et al., Chengdu, China. In Cell Death Dis, 2012
From this unique angle, this review article will discuss the relationship between dysregulated cellular metabolism and cancer drug resistance and how targeting of metabolic enzymes, such as glucose transporters, hexokinase, pyruvate kinase M2, lactate dehydrogenase A, pyruvate dehydrogenase kinase, fatty acid synthase and glutaminase can enhance the efficacy of common therapeutic agents or overcome resistance to chemotherapy or radiotherapy.
