Study TitleGlutaminase inhibition impairs CD8 T cell activation in STK11/Lkb1 deficient lung cancer
Study TypeBiomedical research
Study SummaryTo characterize the impact of KRAS co-mutations KEAP1 and STK11/Lkb1 on the metabolic and immune microenvironment of lung adenocarcinoma in immune-intact models, we generated a cohort of genetically engineered mouse models (GEMMs) to reflect the diverse tumor suppressor landscape seen in patients. Mice carrying the KrasG12D allele (K)21 were crossed with Keap1flox/flox (KK)22 and/or Lkb1flox/flox (KKL, KL)23 mice and genetic recombination induced by intranasal inhalation of Ad5-CMV-Cre adenovirus. We interrogated the metabolites present in lung tumor nodules collected from cohorts of KK, KL and KKL mice.

Sample Preparation:

Sampleprep ID:SP002154
Sampleprep Summary:Tumor tissue was flash frozen and crushed using a mortar and pestle in liquid nitrogen. To the Eppendorf tubes 150 µL of cold 80 % acetonitrile was added and vortexed quickly. The suspension was transferred to a fresh Eppendorf tube. Another 150 µL portion of extraction solvent was added to the tubes, vortexed and the suspension combined with the first portion. To the combined extraction mixture 75 µL of CHCl3 was added and samples were mixed for 1 h in a cool room to ensure complete extraction. The samples were centrifuged at 4 °C at 14.8 g for 10 min, supernatant transferred to new tubes and evaporated at 20 °C under a stream of nitrogen. BSA assay was performed on the protein pellet by dissolving all protein in equal volume of detergent solution (4 % v/v SDS in water). Dried samples were resolubilized in appropriate volume of CHCl3 : MeOH : H2O (1 : 3 :1, v/v) mixture based on measured protein content, shaken for 15 min at room temperature, centrifuged at 4 °C at 14.8 g for 10 min. 100 µL of the supernatant was transferred to LCMS vials. 10 µL injected for metabolomics analysis.
