RNA-seq of human patient-derived xenograft pancreatic cancer PancA6L cells cultured for 14 days with Galactose versus PancA6L cells cultured for 14 days with Glucose

ABSTRACT: The goal of the study was to identify genes and pathways that were altered when human pancreatic ductal adenocarcinoma (PDAC) cancer cells are cultured with different carbon source (Glucose versus Galactose). Primary adherent cultures established from patient-derived xenograft passaged in mice were established (PancA6L). Low passage (< 15) PDX-derived primary PDAC PancA6L cultures were trypsinized and seeded at a concentration of 800,000 cells in p100 plates with RPMI medium supplemented with 10% fetal bovine serum (FBS) and 50 units/mL of penicillin and streptomycin. After 24 h, cells were cultured with either 1) glucose-free DMEM medium (Dulbecco´s Modified Eagle Medium, Thermo Fisher Scientific) supplemented with 5mM glucose (0.9 g/L), 10% FBS, 50 units/mL of penicillin and streptomycin and 1mM of pyruvate [Glucose: OXPHOS-independent conditions] or 2) glucose-free DMEM medium (Thermo Fisher Scientific) supplemented with 5mM galactose (0.9 g/L), 10% FBS, 50 units/mL of penicillin and streptomycin and 1mM of pyruvate [Galactose: OXPHOS-competent enriched conditions]. Sugar concentrations of 5mM were chosen to mimic physiological sugar levels (glucose, 5mM) and to avoid potential biological artifacts mediated by supraphysiological sugar levels. Media for both conditions were changed every day Following 14 days in culture as spheres, Total RNA was isolated by the guanidine thiocyanate (GTC) method using standard protocols. PolyA+ RNA fraction was processed as in Illumina’s ‘‘TruSeq RNA Sample Preparation v2 Protocol’’. The resulting purified cDNA library was applied to an Illumina flow cell for cluster generation (TruSeq cluster generation kit v5) and sequenced on the Genome Analyzer IIx with SBS TruSeq v5 reagents by following manufacturer’s protocols. RNA-seq data sets were analyzed using the tool Nextpresso.
