... pathways, ion and ammonia transporters, hemolymph osmolality and ammonia concentration in Litopenaeus vannamei after injection of 10 −7 and 10 −6 mol DA per shrimp. The data showed a significant increase in crustacean hyperglycemic hormone (CHH) concentration at 1–12 h and a transient significant decrease...

...Lingjun Si; Luqing Pan; Hongdan Wang; Xin Zhang ABSTRACT Effects of ammonia-N (0.05, 2, 10 and 20 mg l −1 ) on the neuroendocrine regulation of ammonia transport were investigated in Litopenaeus vannamei . The results showed that corticotrophin-releasing hormone, adrenocorticotropic hormone...

..., and HEA is a relevant environmental stressor in Lake Magadi ( Wilson et al., 2004 ). Therefore, at present we favour the idea that the branchial Rh proteins are present in the gills to function as ammonia transporters. Under normal conditions, they might well be inactive. However, during HEA...

...C. Michele Nawata; Shigehisa Hirose; Tsutomu Nakada; Chris M. Wood; Akira Kato SUMMARY Rhesus (Rh) protein involvement in ammonia transport processes in freshwater fish has received considerable attention; however, parallel investigations in seawater species are scant. We exposed pufferfish to high...

...C. Michele Nawata; Chris M. Wood; Michael J. O'Donnell SUMMARY Recent experimental evidence from rainbow trout suggests that gill ammonia transport may be mediated in part via Rhesus (Rh) glycoproteins. In this study we analyzed the transport properties of trout Rh proteins (Rhag, Rhbg1, Rhbg2...

These data suggest that Rhesus glycoproteins are important for ammonia transport in the freshwater trout gill, and may help to explain in vivo data...

..., mirroring those in trout exposed to high environmental ammonia. Therefore a dual function for gill and skin Rh proteins in CO 2 and ammonia transport is not evident from these results. Rhag expression, however, responded differentially to high CO 2 and high ammonia, suggesting a possible dual role...
