WebbSHANK family proteins (SHANK1, SHANK2, & SHANK3) have emerged as promising candidates for modeling ASD in mice due to strong genetic evidence showing reproducible genetic mutations of SHANK family genes in ~2% of patients with ASD. We have generated and characterized both isoform specific and complete Shank2 and Shank3 mutant mice. Webb21 mars 2011 · In a 2007 study, Feng showed that another postsynaptic protein found in the striatum, Sapap3, can cause OCD-like behavior in mice when mutated. Communication problems In the new Nature study, Feng and his colleagues found that Shank3 mutant mice showed compulsive behavior (specifically, excessive grooming) and avoidance of social …
Webb9 maj 2012 · Mutations in the synaptic scaffolding protein gene SHANK3 are strongly implicated in autism and Phelan–McDermid 22q13 deletion syndrome. The precise location of the mutation within the Shank3 gene is key to its phenotypic outcomes. Here, we report the physiological and behavioral consequences of null and heterozygous … WebbFör 1 dag sedan · Using just such an experimental setup, Hill-Yardin and her colleagues demonstrated that gut tissue from mice carrying an autism-linked mutation in the gene NLGN3 is more sensitive to drugs that mimic the signaling molecule gamma-aminobutyric acid (GABA) — a result that other researchers had previously shown in brain slices taken …
WebbSHANK3 is a postsynaptic protein, whose disruption at the gen etic level is thought to be responsible for the development of 22q13 deletion syndrome (Phelan–McDermid syndrome) and other non-syndromic ASDs. Here we show that mice with Shank3 gene deletions exhibit self-injurious repetitive grooming and deficits in social interaction.
WebbHere, we disrupted and then restored expression of the ASD-associated gene Shank3 in adult male mice while tracking the encoding dynamics of neurons in the medial …
