KCNA3 and infection: The modulation of miRNAs from the hearts of T. cruzi-infected mice is positively correlated with a parasitemia peak at 30 days post-infection (dpi), as observed for miR-146b, miR-21, miR-142-3p, and miR-142-5p, while a negative correlation is observed for miR-145-5p and miR-149-5p and also suggests the regulation of genes involved in the pathophysiological conditions of experimental infection, such as calcium and potassium channels and electrocardiography (ECG) parameters [116], as shown in Figure 3.
