Hatching gland cells (HGCs) originate from different germ layers between frogs and teleosts, although the hatching enzyme genes are orthologous. Teleostei HGCs differentiate in the meso-endodermal cells at the anterior end of the involved hypoblas...

Six aspartic proteinase precursors, a pro-cathepsin E (ProCatE) and five pepsinogens (Pgs), were purified from the stomach of adult newts (Cynops pyrrhogaster). On sodium dodecylsulfate-polyacrylamide gel electrophoresis, the molecular weights of ...

Syngnathiform fishes carry their eggs in a brood structure found in males. The brood structure differs from species to species: seahorses carry eggs within enclosed brood pouch, messmate pipefish carry eggs in the semi-brood pouch, and alligator p...
The effect of microwave heating (MW) on the activity of a well-known enzyme (catalase) was elucidated by examining the catalase-assisted decomposition of hydrogen peroxide (H2O2 at various heating times (0 to 12 min)). For comparison, conventional...

We investigated the evolution of the hatching enzyme gene using bester sturgeon (hybrid of Acipencer ruthenus and Huso huso), a basal member of ray-finned fishes. We purified the bester hatching enzyme from hatching liquid, yielding a single band ...
