MetabolomicsLactiplantibacillus plantarum PS128 restores microbiota-driven polyamine homeostasis to alleviate autism-like behaviors in Fmr1 knockout mice

Background Autism spectrum disorder (ASD) is biologically heterogeneous and has limited mechanism-informed interventions targeting core behavioral symptoms. Emerging evidence suggests that gut microbial metabolism shapes neurobehavioral outcomes, yet the specific metabolic pathwa...

ProteomicsUncovering the metabolic pleiotropy of FMR1-deficiency in Fragile X Syndrome
ene pleiotropy defines the capacity of a gene to impact multiple phenotypic characters. The Fragile X Mental Retardation 1 (FMR1) gene is a candidate for pleiotropy, as it controls protein synthesis through its product, the translational regulator FMRP. As FMR1 loss-of-function leads to neurodevelop...

TranscriptomicsFMRP-associated MOV10 facilitates and antagonizes miRNA-mediated regulation
The fragile X mental retardation protein FMRP is an RNA binding protein that regulates translation of its bound mRNAs through incompletely defined mechanisms. FMRP has been linked to the microRNA pathway and we show here that it is associated with MOV10, a putative helicase that is also associated w...

TranscriptomicsFMR1 targets distinct mRNA sequence elements to regulate protein expression [Affymetrix]
Fragile-X Syndrome (FXS) is a multi-organ disease leading to mental retardation, macro-orchidism in males, and premature ovarian insufficiency in female carriers. FXS is also a prominent monogenic disease associated with autism spectrum disorders (ASD). FXS is typically caused by the loss of FRAGILE...

TranscriptomicsThe 3’UTR of FMR1 mRNA is a target of miR101, miR129-5p and miR-221: implications for the molecular pathology of FXTAS at the synapse.
While FMR1 is silenced in Fragile X syndrome (FXS), its expression is elevated (2-8 fold) in premutated individuals. These people may develop the Fragile X-associated Tremor Ataxia Syndrome (FXTAS), a late onset neurodegenerative disorder characterized by ataxia and parkinsonism. In addition, people...

TranscriptomicsGenome-wide analysis identifies aberrant methylation in Fragile X syndrome is specific to the FMR1 locus
Fragile X syndrome (FXS) is a common form of inherited intellectual disability and is caused by an expansion of CGG repeats located in the 5Õ untranslated region (UTR) of the FMR1 gene, leading to hypermethylation and silencing of this locus. While the dramatic increase in DNA methylation (DNAm) of ...
