1.4 Gaines Family Home at 3932 Weest Belle Place, St. Louis, Missouri

Following the death of Lloyd's father, his family, the size of which is reported to be anywhere from five to 11 siblings, moved to St. Louis, Missouri in 1926, settling in the city's Central West End neighborhood.

1.4 Lloyd C. Stark, 39th Governor of State of Missouri, 1937-1941

After weeks of debate Taylor’s proposal, House Bill No. 195 was passed and signed by Governor Lloyd Stark.

Defects in inositol 1,4,5-trisphosphate receptor expression, Ca2+ signaling, and insulin secretion in the anx7(+/−) knockout mouse

The mammalian anx7 gene codes for a Ca2+-activated GTPase, which supports Ca2+/GTP-dependent secretion events and Ca2+ channel activities in vitro and in vivo. To test whether anx7 might be involved in Ca2+ signaling in secreting pancreatic β cells, we knocked out the anx7 gene in the mouse and tested the insulin-secretory properties of the β cells. The nullizygous anx7 (−/−) phenotype is lethal at embryonic day 10 because of cerebral hemorrhage. However, the heterozygous anx7 (+/−) mouse, although expressing only low levels of ANX7 protein, is viable and fertile. The anx7 (+/−) phenotype is associated with a substantial defect in insulin secretion, although the insulin content of the islets, is 8- to 10-fold higher in the mutants than in the normal littermate control. We infer from electrophysiological studies that both glucose-stimulated secretion and voltage-dependent Ca2+ channel functions are normal. However, electrooptical recordings indicate that the (+/−) mutation has caused a change in the ability of inositol 1,4,5-trisphosphate (IP3)-generating agonists to release intracellular calcium. The principle molecular consequence of lower anx7 expression is a profound reduction in IP3 receptor expression and function in pancreatic islets. The profound increase in islets, β cell number, and size may be a means of compensating for less efficient insulin secretion by individual defective pancreatic β cells. This is a direct demonstration of a connection between glucose-activated insulin secretion and Ca2+ signaling through IP3-sensitive Ca2+ stores.
