ACOX3 and neoplasm: By performing qRT-PCR, we confirmed that mRNA levels of many molecules involved in fatty acid metabolism, including PPARδ (gene name: Ppard), Pgc1α (gene name: Ppargc1a), Cd36, Acox1, Acox2, Acox3, Sirt1, Hif1a, but not Hadhb, were significantly increased in GA muscle of KPC tumor-bearing Xbp1fl/fl mice compared to corresponding control Xbp1fl/fl mice.
