Collection:
| Collection ID: | CO000394 |
| Collection Summary: | HepG2 cells (ATCC HB-8065) were cultured in MEM containing 10 % (v:v) FBS, 100 U/mL penicillin and 100 mg/mL streptomycin (Invitrogen, Carlsbad, CA), 1 x MEM non-essential amino acids, and 5.5 mM glucose at 37 °C in a 5 % CO2 environment. Cells were grown for four to six passages in 10 cm tissue culture dishes with 14 mL MEM, and transferred to MULTIWELL™ 12 well culture dishes for incubation in 2 mL of the treatment medium. Upon reaching 80 % confluency, the cell culture medium was changed to media representative of experimental condition: 5.5 mM glucose MEM, 5.5 mM glucose MEM + 5 mM glucose, or 5.5 mM glucose MEM + 5 mM fructose. Media was replenished after 24 and 48 h. Cell material was collected at 10 min, 1, 6, and 24 h time points following the 48 h media replacement. Culture dishes were placed on ice and each well was washed twice with 1 mL ice-cold PBS. 4 mL ice-cold 3:1 methanol/H2O extraction solvent was added to each well. Cell material was manually scraped from each well, and the extraction solvent cell material suspension was transferred to collection tubes and frozen at −80 °C prior to further processing. |

| Sample Type: | Cell |
| Collection Location: | Invitrogen, Carlsbad, CA |
| Collection Frequency: | Cell material was collected at 10 min, 1, 6, and 24 h time points following the 48 h media replacement. |
| Tissue Cell Identification: | HepG2 |
Treatment:
| Treatment ID: | TR000414 |
| Treatment Summary: | 3 Treatments: A) Control group of HepG2 cells incubated in media with 5.5 mM glucose (Glc5) B) HepG2 cells incubated in media containing 5.5 mM glucose + 5.0 mM fructose (Glc5Fru5) C) HepG2 cells incubated in media containing 10.5 mM glucose (Glc10) |
| Treatment Protocol Filename: | metabolomic_responses_of_cultured_HepG2_liver_cells.pdf |
| Treatment Protocol Comments: | HepG2 cells incubated in media containing 10.5 mM glucose (Glc10) was included to enable differentiation of metabolic effects caused by fructose from metabolic effects caused by increased hexose resources |
| Cell Media: | Cells were acclimated to their respective media condition for 48 h prior to collection of sample material to obtain a metabolite profile representative of continued exposure instead of response to a sudden change in carbohydrate resources. Media was replenished after 24 and 48 h |
Sample Preparation:
| Sampleprep ID: | SP000407 |
| Sampleprep Summary: | Sample material was thawed on ice, vortexed for 20 s, sonicated for 5 min with a VWR 50HT Ultrasonic Bath (VWR International Inc., Bridgeport, NJ), and separated into 500 μL aliquots. Each aliquot was centrifuged for 5 min @ 14,000 rcf, and supernatant was collected and lyophilized to dryness. Samples was kept on ice and removed only for sonication, centrifugation, and lyophilization steps. Lyophilized material was used for HILIC-QTOF metabolite profiling without additional clean-up steps. Lyophilized material for GC-TOF analysis was redissolved in 1:1 acetonitrile/H2O, vortexed for 10 s, and centrifuged for 5 min @ 14,000 rcf. Supernatant was collected and lyophilized to dryness. |
