Treatment Summary:HADHA Line Creation: Using LentiCrisprV2 plasmid 91 (lentiCRISPRV2 was a gift from Feng Zhang (Addgene plasmid # 52961) two different gRNAs targeted to Exon 1 of HADHA were designed using CRISPRScan 92. Sequences for the gRNAs can be found in Supplemental Table S12. The gRNA and Cas9 expressing plasmids were transiently transfected into the WTC line using GeneJuice (EMD Millipore). 24 hours after transfection, WTCs were puromycin selected for two days and then clonally expanded. DNA of the clones was isolated, the region around the targeting guides was PCR amplified (see guides in Supplemental Table S12) and sequenced to determine the insertion and deletion errors generated by CRISPR-Cas9 system in exon 1 of HADHA. Western analysis was performed to determine the levels of HADHA protein in HADHA mutants. 31 clones were sent for sequencing from gRNA1 experiment, 6 clones (19%) had no mutations while 25 clones (81%) were found to have mutations. 24 clones were sent for sequencing from gRNA2, 1 clone had no mutations (4%) while 23 clones (96%) were found to have mutations. Two of the mutant lines were analyzed further in this study. Glucose and Fatty Acid Media: The base media which we are calling Glucose Media, is RPMI supplemented with B27 with insulin. The fatty acid media is the glucose media with oleic acid conjugated to BSA (Sigma O3008): 12.7μg/mL, linoleic acid conjugated to BSA (Sigma L9530): 7.05μg/mL, sodium palmitate (Sigma P9767) conjugated to BSA (Sigma A8806): 52.5μM and L-carnitine: 125μM. Fatty acid (FA) experiments used this B27 + insulin + the three FAs (oleic acid, linoleic acid and palmitatic acid), in RPMI media. This media was changed every other day during the 6-days or 12-days of treatment.
