Cyprinid herpesvirus 2 (CyHV-2), the etiological agent of herpesvirus haematopoietic necrosis (HVHN) in carp and goldfish, has caused significant economic losses in the aquaculture industry. During viral infection, the host initiates a series of active or passive defences to regulate the process of virus infection. Apoptosis is a key component of active cellular defence, and members of the Bcl-2 family have been shown to play a critical role in the apoptotic process. However, the mechanism of action of the Bcl-2 family in inducing apoptosis during CyHV-2 infection remains unclear. In this study, we revealed the molecular mechanism of miRNA-mediated silver crucian carp BAX (ccBax) in CyHV-2-induced apoptosis for the first time and demonstrated that the overexpression of miR-124 suppressed ccBax expression and significantly down-regulated apoptosis in caudal fin cells of Carassius auratus gibelio (GiCF), while miR-124 inhibitors were the opposite. These studies indicated that miR-124 inhibits CyHV-2-induced apoptosis by reducing the expression of ccBax. Furthermore, the fact that transfection of miR-124 mimics promoted CyHV-2 replication, whereas miR-124 inhibitors inhibited CyHV-2 replication, indicated that miR-124 inhibited CyHV-2-induced apoptosis and contributed to viral replication. All these results suggested that miR-124 suppresses virus-induced apoptosis and promotes viral replication by targeting and regulating ccBax expression
