... biological processes. Accumulation of several metabolites, including specific amino acids, glycerol and gamma aminobutyric acid (GABA), and transcript shifts in the associated pathways for generating these metabolites indicated congruence between changes in the metabolome and gene expression. Ticks treated...

... reduced cell survival in foregut tissue and caused leakage of free proline, total amino acids and proteins from tissues into the hemolymph. The addition of glycerol to the bathing medium reduced freezing injury in fat body cells, as evidenced by reduced leakage of amino acids and proteins. * Author...

.... Cryoprotectant analysis using HPLC showed that the pre-exposure treatment allowed the larvae to accumulate glycerol in the hemolymph. Two genes, glycerol-3-phosphate dehydrogenase ( GPDH ) and glycerol kinase ( GK ), were identified as being associated with glycerol biosynthesis, and were cloned from S. exigua...

... most susceptible to the effects of low temperatures. The concentration of glucose in the posterior chamber of the kidney and concentration of glycerol in the digestive gland were significantly higher in cold-acclimated snails than in non-acclimated ones, suggesting carbohydrate metabolic pathways...

..., 95% of the last-instar nymphs emerged. N. arctica produce both glycerol and ice-binding factors (e.g. antifreeze protein) in response to low temperature. Hemolymph glycerol concentrations increased from 3 mmol l –1 to 930±114 mmol l –1 when temperatures were decreased from 4°C to –8°C, and N. arctica...

...William R. Driedzic; Connie E. Short SUMMARY Rainbow smelt Osmerus modax accumulate glycerol in winter that serves as an antifreeze. Fish were held at 8°C, or subjected to a decrease in water temperature to –1°C over a 19 day period, and subsequently maintained at –1°C from 15 January to 11 May...

...William R. Driedzic; Kathy A. Clow; Connie E. Short; K. Vanya Ewart SUMMARY Rainbow smelt ( Osmerus mordax ) accumulate high levels of glycerol in winter that serves as an antifreeze. Fish were subjected to controlled decreases in water temperature and levels of plasma glycerol, liver metabolites...

... spring. Plasma levels of glycerol, trimethylamine oxide (TMAO) and urea were elevated by December 15 and continued to increase in fish held in ambient conditions. In contrast, fish held under warm conditions exhibited decreased glycerol and urea content in plasma, muscle and liver. Plasma and liver TMAO...

... to the investigation of most metabolic substrates, including fatty acids, glycerol, amino acids and lactate, in addition to glucose. Future application of the continuous infusion technique under steady-state as well as non-steady-state conditions will add a new dimension to the general understanding of fish metabolism...

... conditions for 3 months ( Clegg and Jackson, 1989 ). We found no measurable change in trehalose and glycerol content under these conditions, but did observe a statistically significant decrease in the glycogen content of anoxic cysts. In the present paper we report comparable data from additional studies...
