- "\nAbstract\nAquaporins (AQPs) are integral membrane channels that facilitate the
bidirectional transport of water and sometimes other small solutes across biological
membranes. AQPs are important in mediating environmental adaptations in mosquitoes
and are considered as a novel target for the development of effective insecticides
against mosquitoes. Here, we expressed Aedes aegypti AQP6 (\nAaAQP6) in human embryonic
kidney (HEK) 293 cells and analyzed the water permeability by a conventional swelling
assay, that is, a real‐time change in cell size corresponding to the cell swelling
induced by hyposmotic solution. The swelling assay revealed that \nAaAQP6 is a mercury‐sensitive
water channel. Gene expression studies showed that \nAaAQP6 is highly expressed
in the pupae than other developmental stages. Heterologous expression of \nAaAQP6
in HEK cell was mainly observed intracellularly suggesting \nAaAQP6 possibly could
be a subcellular water channel and may play an osmoregulatory function in the pupae
of \nA. aegypti.\n"
