... in hepatopancreas, expression in gill was 10-fold greater and expression was highest in antennal gland (15-fold greater than in hepatopancreas). Compared with baseline expression levels in intermolt stage,expression of ECaC in antennal gland increased 7.4- and 23.8-fold,respectively, in pre- and postmolt stages...

... membrane Na + /K + -ATPase is a potentially key target for regulation during estivation. Na + /K + -ATPase was investigated in foot muscle and hepatopancreas of the land snail Otala lactea , comparing active and estivating states. In both tissues enzyme properties changed significantly during estivation...
