Drosophila models of phosphatidylinositol glycan biosynthesis class A congenital disorder of glycosylation (PIGA-CDG) mirror patient phenotypes.

Mutations in the phosphatidylinositol glycan biosynthesis class A (PIGA) gene cause a rare, X-linked recessive congenital disorder of glycosylation. Phosphatidylinositol glycan biosynthesis class A congenital disorder of glycosylation (PIGA-CDG) is characterized by seizures, intellectual and developmental delay, and congenital malformations. The PIGA gene encodes an enzyme involved in the first step of glycosylphosphatidylinositol (GPI) anchor biosynthesis.

Serotonergic modulation of appetitive and ingestive behavior in crayfish.

Serotonin is an important modulator of feeding behavior across animal species. In invertebrates, much is known about the regulation of feeding in several model organisms, but comparative data are limited. We examined the modulation of feeding behavior in crayfish by administering serotonin and two serotonin receptor ligands, mianserin and 5-carboxamidotryptamine.
