Publikováno v: Frontiers in Physiology, Vol 8 (2017)

Giant clams live in symbiosis with extracellular zooxanthellae and display high rates of growth and shell formation (calcification) in light. Light-enhanced calcification requires an increase in the supply of Ca2+ to, and simultaneously an augmented

Molecular characterization of three Rhesus glycoproteins from the gills of the African lungfish, Protopterus annectens, and effects of aestivation on their mRNA expression levels and protein abundance.

Autor: You R Chng, Jasmine L Y Ong, Biyun Ching, Xiu L Chen, Kum C Hiong, Wai P Wong, Shit F Chew, Siew H Lam, Yuen K Ip

Publikováno v: PLoS ONE, Vol 12, Iss 10, p e0185814 (2017)

African lungfishes are ammonotelic in water. They can aestivate for long periods on land during drought. During aestivation, the gills are covered with dried mucus and ammonia excretion ceases. In fishes, ammonia excretion through the gills involves

Publikováno v: Frontiers in Physiology, Vol 7 (2016)

African lungfishes can undergo long periods of aestivation on land during drought. During aestivation, lungfishes are confronted with desiccation and dehydration, and their gills become non-functional and covered with a thick layer of dried mucus. Aq

Voltage-Gated Na+ Channel Isoforms and Their mRNA Expression Levels and Protein Abundance in Three Electric Organs and the Skeletal Muscle of the Electric Eel Electrophorus electricus.

Autor: Biyun Ching, Jia M Woo, Kum C Hiong, Mel V Boo, Wai P Wong, Shit F Chew, Yuen K Ip

Publikováno v: PLoS ONE, Vol 11, Iss 12, p e0167589 (2016)

This study aimed to obtain the coding cDNA sequences of voltage-gated Na+ channel (scn) α-subunit (scna) and β-subunit (scnb) isoforms from, and to quantify their transcript levels in, the main electric organ (EO), Hunter's EO, Sach's EO and the sk

Publikováno v: PLoS ONE, Vol 8, Iss 12, p e84298 (2013)

The swamp eel, Monopterus albus, can survive in high concentrations of ammonia (>75 mmol l(-1)) and accumulate ammonia to high concentrations in its brain (4.5 µmol g(-1)). Na(+)/K(+)-ATPase (Nka) is an essential transporter in brain cells, and sinc
