Cross-species comparison of drug handling with near-physiological kidney transporter model. New drug molecules are usually tested in vivo in two preclinical species to gain a more detailed understanding of how they are transported and eliminated through the kidney and also to mitigate risk of renal toxicity in humans. However, these animal models are not always predictive of human responses. To address this problem, robust, comparative in vitro kidney transporter models, such as aProximate™, are powerful tools to compare different species and are much needed to improve in vitro-in vivo extrapolation (IVIVE).

Investigate renal drug transport modalities and drug interactions in vitro. aProximate™ PTCs retain high expression of the relevant transporters involved in drug handling including megalin and cubilin; so are ideal for drug transporter and drug interaction studies of both small and large molecules. Transporters play a major role in the uptake and efflux of drugs across cellular membranes. Drug interactions with transporter proteins are common and can act either as substrates and/or inhibitors, a role which is best be identified during the early-stages of drug development to define the absorption, distribution, metabolism and excretion (ADME) profile. Using our scientific expertise, Newcells provides transporter assays using the aProximate™ model to support your specific requirements and understand potential drug interactions.
