Study ID	ST003243
Study Title	Lipidomic analysis of serum from WT, liver-specific Gclc KO, liver-specific Nrf2 KO, and liver-specific Gclc-Nrf2 DKO mice.
Study Summary	The rate-limiting enzyme in glutathione (GSH) synthesis is Gclc. GSH synthesis is suggested to be implicated in lipogenesis. Loss of GSH synthesis is suggested to increase the activity of NRF2. To examine the impact of GSH and NRF2 on lipid abundance in serum, we performed lipidomic analysis of serum from WT, liver-specific Gclc KO, liver-specific Nrf2 KO, and liver-specific Gclc-Nrf2 DKO mice.

Sample Preparation:

Sampleprep ID:	SP003369
Sampleprep Summary:	For serum for WT, liver-specific Gclc KO, liver-specific Nrf2 KO, and liver-specific Gclc-Nrf2 DKO, 20 µL of mouse serum was combined with 180 µL of chloroform:methanol extraction solvent (v:v=1:2) containing internal standards at the final concentrations: 5nM D7-Sphinganine (Avanti Polar Lipids Inc., Cat# 860658), 12.5nM D3-Deoxysphinganine (Avanti Polar Lipids Inc., Cat# 860474), and SPLASH LIPIDOMIX (1:1000, Avanti Polar Lipids Inc., Cat# 330707). After sonicating (1400 rpm, 20°C, 5 min), the extracts were cleared by centrifugation (17,000g, 20°C, 10 min), and the lipids in the supernatant were analyzed by LC-MS.
