cfa-mir-151: Cfa-mir-151 is a microRNA that has been identified as a regulator of IgSF genes [PMC7689213]. In a study comparing dogs with mitral valve disease (MMVD) to healthy dogs, cfa-mir-151 was found to be significantly upregulated in the eccentric hypertrophy group [PMC8062772]. In another study comparing dogs with various heart diseases, cfa-mir-151 was found to be significantly upregulated in the group with patent ductus arteriosus (PDA) [PMC8542680]. Additionally, the 5' seed region of cfa-mir-151 was found to be partially complementary to the mRNA of NP and NS1 of the avian influenza H3N2 virus [PMC8779696]. These findings suggest that cfa-mir-151 may play a role in cardiac hypertrophy and potentially have implications in viral infections. Further research is needed to fully understand the function and significance of cfa-mir-151 in these contexts [PMC8062772][PMC8542680][PMC8779696].
