/ml, the LLOQ from the analytical system. Roughly calculated, that would correspond to a bioavailability of 0.025 , if in theory the complete dose applied (one hundred mg/kg) would be absorbed and not metabolized (blood volume calculated in line with reference 34). Species variations within the bioavailability of drugs are frequent (35) and could possibly clarify the reduced bioavailability observed in our study in rats. In conclusion, determined by in vitro and in vivo studies, drug-drug interactions are unlikely to take place for the two combinations albendazole-oxantel pamoate and albendazole-mebendazole. Having said that, pharmacokinetic research in humans may possibly be valuable to provide additional information regarding the safety profiles of those combinations.FUNDING INFORMATIONThis function, like the efforts of Jennifer Keiser, was funded by EC | European Analysis Council (ERC) (614739-A_HERO).

FIP1L1-PDGFRA is really a leukemogenic fusion kinase that causes chronic eosinophilic leukemia. As a constitutively active kinase, FIP1L1-PDGFRA stimulates downstream signaling molecules, major to cellular proliferation along with the generation of an anti-apoptotic state. Contribution with the N-terminal FIP1L1 portion is vital for FIP1L1-PDGFRA to exert its complete transforming activity, but the underlying mechanisms have not been totally characterized. We identified PIAS1 as a FIP1L1-PDGFRA association molecule by yeast two-hybrid screening. Our analyses indicate that the FIP1L1 portion of FIP1L1-PDGFRA is essential for efficient association with PIAS1. As a consequence in the association, FIP1L1-PDGFRA phosphorylates PIAS1. Additionally, the kinase activity of FIP1L1-PDGFRA stabilizes PIAS1. Therefore, PIAS1 is one of the downstream targets of FIP1L1-PDGFRA. In addition, we identified that PIAS1, as a SUMO E3 ligase, sumoylates and stabilizes FIP1L1PDGFRA. Moreover, suppression of PIAS1 activity by a knockdown experiment resulted in destabilization of FIP1L1-PD.
