mRNA expression of Oct3 (A), Octn1 (B), and Octn2 (C) in the hearts of CVB3-infected A.BY/SnJ and C57/BL/6 mice. Oct(n) and 18S rRNA expression was determined in control animals and 4, 8, 12, and 28 days after CVB3 infection. Values are presented as mean ± SD in relation (rel.) to day 0. Statistical significance was tested versus untreated mice using the Mann-Whitney U-test (*P < 0.05).
