Study ID	ST003760
Study Title	Untargeted lipidomics of combination gemcitabine/paclitaxel attenuated (CombAT) PDAC cells
Study Summary	In this work produced combination gemcitabine/paclitaxel attenuated (CombAT) Panc1 and MiaPaCa2 cells, and used untargeted lipidomics to profiled changes in their lipidome. This dataset includes CombAT cells and control (CON) cells, alongside internal quality controls (iQC) and blank samples for background subtraction (as described under sample prep). These data revealed extensive increases across 166 lipid species in Panc1 CombAT cell lines compared with CON, including increases in many triacylglycerol (TG) species and total TG. Increases were also seen in several TG species in CombAT MiaPaCa2 cells, with 30 lipid species increased in total when compared with CON. Data were analysed using MS-DIAL v4.9.

Project Title:	Untargeted lipidomics of combination gemcitabine/paclitaxel attenuated (CombAT) PDAC cells
Project Summary:	Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive disease with few treatment options and poor survivability. In this work we sought to characterise metabolic adaptations to gemcitabine (GEMC)-based chemotherapy exposure to discover new therapeutic targets for improving treatment efficacy. This project examined the impact of combination gemcitabine/paclitaxel resistance on the lipidomics of Panc1 and MiaPaCa2 PDAC cell lines, finding upregulated de novo lipogenesis in both cell lines.

Collection:

Collection ID:	CO003886
Collection Summary:	Samples were obtained from established immortalised adherent human pancreatic ductal adenocarcinoma cells (Panc1 & MiaPaCa2). Cells were cultured in high glucose DMEM containing 4.5 g/L glucose and 4 mM glutamine and were supplemented with 10% FCS. Cells were cultured under 5% CO2 at 37ºC and routinely passaged every 2-3 days (when ~80-90% confluent). Cell lines were regularly screened for mycoplasma infection.
Sample Type:	Pancreas

Treatment:

Treatment ID:	TR003902
Treatment Summary:	Combination gemcitabine/paclitaxel attenuated (CombAT) cells were produced by serial treatment with escalating doses of gemcitabine/paclitaxel (10:1) for approximately 12 weeks. The final concentration of gemcitabine for Panc1 cells was 28 nM (2.8 nM paclitaxel), and 8 nM (0.8 nM paclitaxel) for MiaPaCa2 cells.

Sample Preparation:

Sampleprep ID:	SP003899
Sampleprep Summary:	Lipids were extracted from cells grown to 80-90% confluency in 6 well plates using a modified methyl tert-butyl ether (MTBE) method. Adherent cells were washed with ice-cold PBS and scraped into methanol containing 0.01% butylated hydroxytoluene and 100 pmol each of internal standards (phosphatidylcholine 19:0/19:0, phosphatidylethanolamine 17:0/17:0, phosphatidylserine 17:0/17:0, lysophosphatidylcholine 17:0, lysophosphatidylethanolamine 14:0, phosphatidylglycerol 17:0/17:0, phosphatidic acid 17:0/17:0, ceramide d18:1/17:0, dihydrosphingomyelin 12:0, cholesteryl ester 22:1, diacylglycerol 17:0/17:0, D5-triacylglycerol 16:0/16:0/16:0 and cardiolipin 14:0/14:0/14:0/14:0). An empty well was also scraped for use in background subtraction. To this, MTBE was added at a ratio of 3:1 v/v, and extracts were rotated overnight at 4ºC. Following overnight rotation, 1 part of ice-cold 150 mM ammonium acetate was added, samples were vortexed vigorously and centrifuged at 2000 x g for 5 min. The upper organic phase containing lipids was transferred into a 1.5 mL autosampler vial and dried under N2 at 37ºC Dried lipids were reconstituted in chloroform:methanol:water (60:30:4.5 v/v/v), transferred to a sleeved vial, and stored at -20ºC until analysis. The aqueous phase containing the protein pellet was dried under N2 and digested with 1M NaOH overnight at 4ºC. Digested protein was diluted 1:2 v/v with water and protein concentration was determined using a Pierce BCA assay kit (ThermoFisher Scientific)
