title: The GABA<sub>A</sub> Receptor is an FMRP Target with Therapeutic Potential in Fragile X Syndrome

description: ABSTRACTPrevious research indicates that the GABA<sub>A</sub>ergic system is involved in the pathophysiology of the fragile X syndrome, a frequent form of inherited intellectual disability and associated with autism spectrum disorder. However, the molecular mechanism underlying GABA<sub>A</sub>ergic deficits has remained largely unknown. Here, we demonstrate reduced mRNA expression of GABA<sub>A</sub> receptor subunits in the cortex and cerebellum of young <i>Fmr1</i> knockout mice. In addition, we show that the previously reported underexpression of specific subunits of the GABA<sub>A</sub> receptor can be corrected in YAC transgenic rescue mice, containing the full-length human <i>FMR1</i> gene in an <i>Fmr1</i> knockout background. Moreover, we demonstrate that FMRP directly binds several GABA<sub>A</sub> receptor mRNAs. Finally, positive allosteric modulation of GABA<sub>A</sub> receptors with the neurosteroid ganaxolone can modulate specific behaviours in <i>Fmr1</i> knockout mice, emphasizing the therapeutic potential of the receptor.

It has a cosmopolitan distribution and has been reported from Australia based on morphological studies, but this has not been confirmed with molecular data. To address this knowledge gap and explore the phylogenetic diversity within the group, we investigated the species delimitation of <i>P. echinospora </i>and related species from southern Australia, using multilocus phylogenetic analyses of nuclear rDNA internal transcribed spacer ITS1-5.8S-ITS2 (ITS), partial 28S rRNA, and <i>rpb2 </i>(second largest subunit of RNA polymerase II) and morphological examination of fungarium specimens. Based on these analyses, we confirm the occurrence of <i>P. echinospora </i>in Australia and formally describe two new species, <i>P. austroechinospora </i>and <i>P. meridionalis</i>. <i>Peziza austroechinospora </i>is 20 typically found on burnt ground and has spiny ascospores that are larger and proportionately longer than those of <i>P. echinospora</i>. <i>Peziza meridionalis </i>has smooth ascospores, similarly to the closely related species <i>P. subvesiculosa </i>from the Northern Hemisphere, but with smaller ascospores and an ecology not associated with burnt soil. The occurrence of <i>Peziza meridionalis </i>as an endophyte on orchid roots is also discussed.
