| Study Title | Metabolomics Adaptation of Juvenile Pacific Abalone Haliotis discus hannai to Heat Stress |
| Study Summary | We compared two groups of abalones (from the same population) with different temperature acclimation history, through their survival at acute heat treatment and metabolites changes. The results indicated significantly higher survival for the high temperature acclimation group. Both groups experienced mitochondrial homeostasis break down during heat treatment, while the higher temperature acclimation group accumulated more metabolites beneficial to metabolic homeostasis, including various dipeptides, antioxidants, and neuroprotective substances. |

Sample Preparation:
| Sampleprep ID: | SP001406 |
| Sampleprep Summary: | 50 mg of sample was taken and placed in an Eppendorf tube, followed by the addition of 1000 µl extraction solvent containing an internal target (V methanol : V acetonitrile : V water = 2 : 2 : 1, containing internal standard 2 µg/ml). The mixture was homogenized in ball mill for 4 min at 45 Hz, then ultrasound treated for 5min (incubated in ice water). After homogenization for 3 times, the mixture was incubated for 1 h at -20 °C to precipitate proteins. Centrifugation was performed at 12000 rpm for 15 min at 4 °C. A total of 825 µl supernatant was carefully transferred into a fresh Eppendorf tube, and dried in a vacuum concentrator without heating. 200 µl extraction solvent (V acetonitrile: V water = 1:1) was then added for reconstitution, followed by vortex 30 s and sonicated for 10 min (4 °C water bath), centrifuge for 15 min at 12000 rpm (4 °C). 75 µl supernatant was transferred into a fresh 2 ml LC/MS glass vial for UHPLC-QTOF-MS analysis, while another 20 µl was taken from each sample and pooled as QC samples. Six technical replicates were conducted to QC sample with 75 µL each for UHPLC-QTOF-MS analysis. |
