A. GRP78 was overexpressed by adenovirus infection in NRVMs. After PE treatment for 24 hours, cells were harvested for immunofluorescent staining of α-done between control and TG groups after.B. GRP78 overexpression in NRVMs led to more profound hypertrophic growth as shown by increase in cardiac cell size. N = 91–93. C. Overexpression of GRP78 led to increase in protein synthesis, assessed by radioactive leucine incorporation assay. N = 6. D. Anf protein level was augmented by GRP78 overexpression in NRVMs after PE treatment. E. Quantification of D showed significant upregulation of Anf protein. N = 9. F. Anf mRNA level was significantly increased by GRP78 overexpression in NRVMs. N = 3–5. *, p < 0.05; **, p < 0.01; ***, p < 0.001.
