Gene expression analysis of hamster heart. RNA was extracted from hearts of hamsters infected with Delta or Omicron BA.2 at 2 or 7 dpi. The expression of genes important for cardiac function were measured by RT-qPCR, normalised to B2m expression. Data are presented as mean ± SEM, n = 3 biological replicates. Statistical analysis was performed using one-way ANOVA followed by Dunnett’s multiple comparisons test, relative to mock; *p < 0.05, **p < 0.01
