Fig. 6. Changes in protein expression associated with cardiac hypertrophy in
transgenic hearts. Western blot analysis of heart lysates from 3-day- to
4-week-old wild-type and
MHC/Ncad (A) and
MHC/Ecad (B)
transgenic mice shows the time course of the expression of the transgene in
relation to other intercalated disc proteins. Note the dramatic decrease in
Cx43 protein in the 4-week-old
Ecad heart compared with
Ncad,
consistent with the severe hypertrophy response caused by E-cadherin. GAPDH
signal shows loading of samples between lanes. tg, transgene; d, days; w,
weeks.
