Desmin, ZO-1, N-cadherin, and Cx43 expression in rat hearts. Lysates were prepared from nonfailing (N) and failing (F) hearts and rats treated with streptomycin (SM). (a) Western blots used antibodies against desmin, Cx43, N-cadherin, and ZO-1. (b) qPCR was used to test for mRNA for desmin, Cx43, N-cadherin, and ZO-1. ∗p < 0.05 vs nonfailing heart.
