In rodents, the Lsamp gene has been implicated in trait anxiety, fear reaction and fear conditioning. Human data link the LSAMP gene to several psychiatric disorders. In this study, we presented a general phenotypic characterization of Lsamp gene-deficient mouse line, created by deleting exon 1b. These mice displayed no gross sensory-motor deficiencies, no(More)
As different kinds of enrichment equipment are applied to standard rodent laboratory housing conditions in Europe (Directive 2010/63/EU) and worldwide, it is essential to understand how it may influence the brain and behaviour of animals. We observed common inbred mouse strains 129S6/SvEv/Tac (129) and C57BL/6 Bkl (B6) reared in 3 different environments:(More)
Limbic system-associated membrane protein (LSAMP) is a neural cell adhesion molecule involved in neurite formation and outgrowth. The purpose of the present study was to characterize the distribution of alternatively transcribed Lsamp isoforms in the mouse brain and its implications on the regulation of behavior. Limbic system-associated membrane protein 1b(More)
Limbic system associated membrane protein (Lsamp) gene is involved in behavioral adaptation in social and anxiogenic environments and has been associated with a broad spectrum of psychiatric diseases. Here we studied the activity of alternative promoters of Lsamp gene in mice in three rearing conditions (standard housing, environmental enrichment and social(More)
Wolfram syndrome (WS) is a rare autosomal-recessive disorder that is caused by mutations in the WFS1 gene and is characterized by juvenile-onset diabetes, optic atrophy, hearing loss and a number of other complications. Here, we describe the creation and phenotype of Wfs1 mutant rats, in which exon 5 of the Wfs1 gene is deleted, resulting in a loss of 27(More)
IgLON family is composed of five genes: Lsamp, Ntm, Opcml, Negr1, and Iglon5; encoding for five highly homologous neural adhesion proteins that regulate neurite outgrowth and synapse formation. In the current study we performed in silico analysis revealing that Ntm and Opcml display similar genomic structure as previously reported for Lsamp, characterized(More)
