Blood expression profiles of fragile X premutation carriers identify genes involved in neurodegenerative and infertility phenotypes [SHSY5Y]

ABSTRACT: Fragile X premutation carriers (fXPC) of the CGG expansion in the 5M-bM-^@M-^Y-UTR of the fragile X mental retardation 1 (FMR1) gene are at high risk of Fragile X Tremor/Ataxia Syndrome (FXTAS), and females might undergo Premature Ovarian Failure (POF1). We have evaluated the peripheral blood gene expression profiles of fXPC and detected a strong deregulation of genes enriched in FXTAS-relevant biological pathways, including inflammation, and neuronal homeostasis and survival. More than 30% of differentially expressed correspond to long non-coding RNAs (lncRNAs). Several deregulated genes (CASP3, DFFA, APP, AKT1, COX6C, COX7B, SOD1, RNF10, HDAC5, ATXN7, ATXN3 and EAP1) were validated in brain samples of a mouse model of FXTAS and in neuronal cells expressing the expanded FMR1 5M-bM-^@M-^Y-
