The liver contains two systems for the removal of ammonia-the urea cycle and the enzyme glutamine synthetase. These systems are expressed in a complementary fashion in two distinct populations of hepatocytes, referred to as periportal and perivenous cells. One of the unresolved problems in hepatolog

## Abstract Cytosolic phospholipase A~2~α (cPLA~2~α) is a rate‐limiting key enzyme that releases arachidonic acid (AA) from membrane phospholipid for the production of biologically active lipid mediators including prostaglandins, leukotrienes and platelet‐activating factor. cPLA~2~α is translocated
## Abstract The non‐canonical Wnt/Ca^2+^ signaling pathway has been implicated in the regulation of axis formation and gastrulation movements during early __Xenopus laevis__ embryo development, by antagonizing the canonical Wnt/β‐catenin dorsalizing pathway and specifying ventral cell fate. However
