Key result
miR-222a overexpression suppresses DHAV-1 replication in duck embryo fibroblasts by downregulating ITGB3.
Why the study?
The interplay between duck hepatitis A virus 1 infection and regulatory microRNAs remains ambiguous.

miR-222a may inhibit DHAV-1 in duck cells; leaves open in vivo efficacy and therapeutic translation.
p-value: p=<0.01
miR-222a acts as an antiviral factor against DHAV-1 by modulating its replication via interaction with ITGB3 in duck embryo fibroblasts.
Sui et al. (2022) studied Duck Hepatitis A Virus Type 1 Infection. miR-222a mimics vs. negative control mimics was evaluated on DHAV-1 viral titers (TCID50) and protein expression (p=<0.01). Overexpression of miR-222a significantly suppressed DHAV-1 replication in duck embryo fibroblasts by directly targeting and downregulating integrin subunit beta 3 (ITGB3).
