...Allison M. King; Jantina Toxopeus; Thomas H. MacRae Females of the crustacean Artemia franciscana produce either motile nauplii or gastrula stage embryos enclosed in a shell impermeable to nonvolatile compounds and known as cysts. The encysted embryos enter diapause, a state of greatly reduced...

... in animal mitochondrial gene expression. We have used embryos of the brine shrimp Artemia franciscana to test hypotheses regarding message stability and polyadenylation under conditions simulating anoxia-induced quiescence. In response to anoxia, these embryos undergo a profound and acute metabolic...

...Ana Martinez-Lamparero; Marie-Carmen Casero; Javier Ortiz-Caro; Leandro Sastre SUMMARY Artemia franciscana embryos can suspend their development and metabolism at the gastrula stage to enter a state of cryptobiosis, forming cysts. Embryonic development and metabolism can be resumed under favorable...

...Brian D. Eads; Steven C. Hand SUMMARY In response to anoxia, embryos of the brine shrimp Artemia franciscana are able coordinately to downregulate metabolism to levels low enough to permit survival for several years at room temperature. In addition to dramatic decreases in free ATP levels and heat...

...J. I. Spicer; M. M. El-Gamal ABSTRACT The ability to regulate O 2 uptake during exposure to acutely declining O 2 tensions developed early (stage 6) in the brine shrimp Artemia franciscana and co-occurred with the appearance of a functional heart and gills. Culture under chronic hypoxia resulted...

...Thomas J. Anchordoguy; Steven C. Hand ABSTRACT Encysted gastrulae of Artemia franciscana are known to enter a reversible state of quiescence promoted by anoxia, during which the half-life of cytochrome oxidase is prolonged up to 77-fold. This observation suggests that proteolytic pathways within...
