Iron : ftn-1

ftn-1 mRNA steadily increases 2-fold as FAC (ferric ammonium citrate) concentration increases from 0.33 to 6.6 mg/ml. In worms grown in the presence of DF (deferoxamine), an iron chelator, ftn-1 mRNAs decrease 10-fold.

Iron : ftn-2

As FAC (ferric ammonium citrate) concentration increases from 0.33 to 6.6 mg/ml, a smaller, but consistent, 0.5-fold increase is observed for ftn-2 mRNA. In worms grown in the presence of DF (deferoxamine), an iron chelator, ftn-2 mRNAs decrease 2-fold.
