Serotonin (5-HT) regulates a wide range of behaviors in Caenorhabditis elegans, including egg laying, male mating, locomotion and pharyngeal pumping. So far, four serotonin receptors have been described in the nematode C. elegans, three of which are G protein-coupled receptors (GPCR), (SER-1, SER-4 and SER-7), and one is an ion channel (MOD-1).

Duchenne muscular dystrophy, a genetic disease caused by the absence of functional dystrophin, remains without adequate treatment. Although great hopes are attached to gene and cell therapies, identification of active small molecules remains a valid option for new treatments. We have studied the effect of 20 approved pharmaceutical compounds on the muscles(More)
We previously reported the use of the cheap and fast-growing nematode Caenorhabditis elegans to search for molecules, which reduce muscle degeneration in a model for Duchenne Muscular Dystrophy (DMD). We showed that Prednisone, a steroid that is generally prescribed as a palliative treatment to DMD patients, also reduced muscle degeneration in the C.(More)
BACKGROUND Because of the increasingly concern of consumers and public policy about problems for environment and for public health due to chemical pesticides, the search for molecules more safe is currently of great importance. Particularly, plants are able to fight the pathogens as insects, bacteria or fungi; so that plants could represent a valuable(More)
The Pea Albumin 1 subunit b (PA1b) peptide is an entomotoxin extracted from legume seeds with lethal activity towards several insect pests. Its toxic activity occurs after the perception of PA1b by a plasmalemmic proton pump (V-ATPase) in the insects. Assays revealed that PA1b showed no activity towards mammalian cells displaying high V-ATPase activity.(More)
