Study ID	ST002996
Study Title	Tissue Lipidomic Profiling for Detection of Non-Small Cell Lung Cancer
Study Summary	UPLC-HRMS analysis was performed on AC and SCC patients. OPLSDA classfication was performed on tumor vs. ANT and DNT samples. Panels of discriminant features were identified. The biomarkers identified in discovery set samples for each binary classification were confirmed by using a set of validation samples, which were run separately. Additionally, paired analysis showed the abundance of discriminant compounds has significant altered in tumor tissues compared to corresponding DNT and ANT samples, reflecting the lipid characteristics related to tumor in situ and cancer cell signaling.

Sample Preparation:

Sampleprep ID:	SP003115
Sampleprep Summary:	Frozen tissue samples were thawed on ice. Each tissue sample was cut into small pieces and accurately weighed.To 100 mg tissue sample, 1 mL precooled 80% methanol was added and the sample was homogenized (60 Hz, 90 s) in a tissue homogenizer (Jingxin, JX-24, Shanghai, China). After vortexing for 1 min, the mixture was incubated at -80 °C for 4 hours, followed by centrifuging at 14,000 × g for 10 min at 4 °C. The supernatant was transferred to a new tube. To the rest of the sample, 400 μL dichloromethane/ methanol (3:1, v/v) was added for lipid extraction. The sample mixture was then vortexed twice, each time for 30 s, followed by incubation at -80 °C for 30 min. After homogenization (60 Hz, 90 s) and centrifugation of the sample at 14,000 × g for 10 min at 4 °C, the supernatant was collected and dried under a speed vacuum concentrator.
