Example Input:  [ ( 3 ) H ] azPC bound recombinant PPARgamma with an affinity ( K ( d ) ( ( app ) ) approximately 40 nm ) that was equivalent to rosiglitazone ( BRL49653 ) , and competition with rosiglitazone showed that binding occurred in the ligand - binding pocket .
Example Output: recombinant PPARgamma

Example Input:  Thus , we set out to find differences in the modes of proliferative and apoptotic responses to TNF - alpha .
