Is anyone aware what Phase 2 metabolism A549 lung cancer cells are
capable of? Can they glucuronidate or sulfate drugs? I can't really
find anything on this doing a quick Medline search. If you know of a
reference that would be fantastic.
Thank you in advance,

Dear Peter,
In our hands A549 cells are metabolically very capable cells. However, I
have no direct information on Phase 2 metabolism in this cell line but
being a lung cell I'd assume they would express 'reasonable' levels of
conjugating enzymes. This cell line is also in the NCI cell line panel
and more information may be gleaned from NCI's Website. The following
references (ex Medline) may be useful:
