Fig. 7. Time course of ANF expression in wild-type and transgenic hearts. Northern
blot analysis of ANF mRNA in
MHC/Ncad and
MHC/Ecad hearts from
3-day- to 4-week-old animals (A). GAPDH signal shows loading of samples
between lanes. (B) Graphic comparison of changes in ANF mRNA levels between
wild-type and transgenic littermates. Note the increase in ANF expression in
Ecad heart at one week of age compared with
Ncad. ANF mRNA
levels were normalized to GAPDH mRNA levels. tg, transgene; d, days; w,
weeks.
