ZIKV infection reduces Cx43 protein levels in neonatal heart tissue and isolated cardiomyocytes. ( A ) Western blotting analysis of the heart tissues. Heart tissues were collected at 11 dpi from the 1-day-old C57BL/6 mice injected intraperitoneally with ZIKV strain PRVABC59 (10 6 PFU/mouse) or PBS ( n = 3/group). Homogenized heart tissues were subjected to western blot assays for Cx43, Tubulin, and ZIKV NS3 detection. ( B ) Western blotting analysis of the cardiomyocytes. Cardiomyocytes were isolated from the hearts of six 1-day-old mice and infected with ZIKV (MOI = 1) for 24 h. MG132 (5 or 10 µM), a ubiquitin-proteasome process inhibitor, was added to the cells 6 h before harvesting the cells. Whole-cell lysates were analyzed by western blot using anti-Cx43, anti-ZIKV NS3, and anti-tubulin antibodies. ( C ) RT-qPCR analysis of Cx43 mRNA levels. Relative Cx43 mRNA levels were measured in mock- or ZIKV-infected cardiomyocytes at 12, 24, and 48 hpi, normalized to GAPDH expression.
