Recent studies have established a role for the phosphoinositide (PI) cycle in the early patterning of Xenopus mesoderm. In explants, stimulation of this pathway in the absence of growth factors does not induce mesoderm, but when accompanied by growth

Wnt genes encode secreted proteins which are implicated in receptor-mediated cell-cell signaling events important in embryogenesis, but the second messenger systems modulated by Wnts have not been identified. We report that ectopic expression of Xwnt

A role for the phosphatidylinositol (PI) cycle signal transduction pathway in Xenopus mesoderm induction has been revealed by observations of PI cycle activation coincident with this process, combined with the demonstration that Li+ (a PI cycle inhib

Propagating Ca2+ waves are a characteristic feature of Ca(2+)-linked signal transduction pathways. Intracellular Ca2+ waves are formed by regenerative stimulation of Ca2+ release from intracellular stores by Ca2+ itself. Mechanisms that rely on eithe

Calcium-induced calcium release (CICR) may function widely in calcium-mediated cell signaling, but has been most thoroughly characterized in muscle cells. In a homogenate of sea urchin eggs, which display transients in the intracellular free calcium

Mesoderm induction and body axis determination in frog (Xenopus) embryos are thought to involve growth factor-mediated cell-cell signaling, but the signal transduction pathways are unknown. Li+, which inhibits the polyphosphoinositide (PI) cycle sign

It can be argued that the calcium ion is the oldest recognized signal transduction molecule, whether one dates the birth of this recognition with Ringer’s 1883 studies1 on the requirement for extracellular Ca2+ in myocardial contraction, or with He

The thrombin receptor is a G protein-coupled receptor, but the G proteins functionally coupled to this receptor in human platelets are not yet definitively identified. Thrombin stimulation of platelets leads to phospholipase C-mediated increases in i

We studied the fusion of nuclear vesicles bound to chromatin in Xenopus egg extracts. Fusion was inhibited by 5 mM BAPTA, a Ca2+ buffer that suppresses cytosolic [Ca2+] gradients. The BAPTA-inhibited step in fusion was biochemically distinct from, an
