These findings suggest that continuous exposure to LET may perturb sex differentiation in carp, the molecular mechanism not only involve inhibition of cytochrome P450 aromatase activity, but also the changes of upstream genes in sex differentiation. So, LET can be used as a r...

The expression levels of BmARM-like protein showed similar trends with transcriptional levels in the midgut following BmNPV infection. Based on the analysis above, we specul...
