We amplified and characterized the BmDaxx gene of the silkworm (Bombyx mori) by real-time quantitative polymerase chain reaction (RT-qPCR). The expression levels of BmDaxx and its downstream genes BmFadd and BmDredd showed significant increases after overexpression of BmDaxx. However, the expression...
