Pyrrolizidine Alkaloids 60-83 ATP binding cassette subfamily B member 1 Homo sapiens 122-127 24375927-11 2014 The passage of the noncyclic PA Hn and Em is reduced by an ABCB1-driven efflux into the gastrointestinal lumen resulting in a decreased oral bioavailability. Pyrrolizidine Alkaloids 29-31 ATP binding cassette subfamily B member 1 Homo sapiens 59-64
