Study ID	ST000894
Study Title	Analysis of the effects of Tyrosine Kinase Inhibitors Sunitinib and Erlotinib on Liver Metabolism In Vivo
Study Summary	Background.More than 90 tyrosine kinases have been implicated in the pathogenesis of malignant transformation and tumor angiogenesis. Tyrosine kinase inhibitors (TKIs) have emerged as effective therapies in treating cancer by exploiting this kinase dependency. The tyrosine kinase inhibitor erlotinib targets epidermal growth factor receptor (EGFR), whereas sunitinib targets primarily vascular endothelial growth factor receptor (VEGRF) and platelet-derived growth factor receptor (PDGFR). TKIs impact the function of non-malignant cells had have on- and off-target toxicities, including cardiotoxicities. Most of the reports of sunitinib have identified cardiotoxic effects, whereas erlotinib was less often found to have these effects. We hypothesized that the deleterious effects of TKIs were related to their impact on cardiac metabolism. Methods. C57BL/6 mice (10/group) were treated with therapeutic doses of sunitinib (40 mg/kg), erlotinib (50 mg/kg), or vehicle daily for 2 weeks. Echocardiographic assessment of the heart in vivo identified significant systolic dysfunction consistent with cardiotoxicity compared to vehicle treated controls. Heart, skeletal muscle, liver, and serum were flash frozen and prepped for non-targeted GC-MS metabolomics analysis. Results. Compared to vehicle treated controls, sunitinib treated mice had significant decreases insystolic function, whereas erlotinib treated mice did not. Non-Targeted metabolomics analysis of heart identified identified significant decreases in Docosahexaenoic acid (DHA), Arachidonic Acid/Eicosapentaenoic acid (EPA), O-Phosphocolamine, and 6-Hydroxynicotinic acid after sunitinib treatment. DHA was significantly decreased in skeletal muscle (quadriceps femoris), with elevations in cholesterol were identified in liver and elevated ethanol amine in serum. In contrast, erlotinib affected only one metabolite elevated (spermidine significantly increased).Conclusions.Mice treated with sunitinib had exhibited systolic dysfunction within two weeks, with significantly lower heart and skeletal muscle levels of long chain omega-3 fatty acids docosahexaenoic acid (DHA), arachidonic acid (AA)/eicosapentaenoic acid (EPA) and increased serum O-Phosphocholine phospholipid. This is the first link between sunitinib-induced cardiotoxicity and depletion in the polyunsaturated fatty acids (PUFAs) and inflammatory mediators DHA and AA/EPA in the heart, possibly by affecting mitochondria function where they have vital roles on calcium channels.

Chromatography Summary:	GC/MS methods follow previous studies using a 6890 N GC connected to a 5975 Inert single quadrupole MS (Agilent Technologies, Santa Clara, CA) (Bonikos et al. 1975; Fiehn 2008; Kind et al. 2009). The two wall-coated, open-tubular GC columns connected in series are both from J&W/Agilent, DB5-MS, 15 meters in length, 0.25 mm in diameter, with an 0.25-l m luminal film. Positive ions generated with conventional electron-ionization at 70 eV are scanned broadly from 600 to 50 m/z in the detector throughout the 45 min cycle time.
