Regulation of a truncated isoform of AMP-activated protein kinase α (AMPKα) in response to hypoxia in the muscle of Pacific oyster Crassostrea gigas
AMP-activated protein kinase α (AMPKα) is a key regulator of energy balance in many model species during hypoxia. In a marine bivalve, the Pacific oyster Crassostrea gigas, we analyzed the protein content of addu...

In Vivo RNA Interference of a Gonad-Specific Transforming Growth Factor-β in the Pacific Oyster Crassostrea gigas
We investigated the role of oyster gonadal TGFβ (og-TGFβ) in the reproduction of Crassostrea gigas, using an in vivo RNA interference approach. We designed double-stranded RNA targeting og-TGFβ, which is specific...
