We firstly found and confirmed that miR-19b-3p could act on FXR1.
3′ UTR and reversely be regulated by FXR1.
Both FMR1 and FXR1 are important genes for the process of FXS.
FXR1, USP32, RAB18 and Dusp6 are target genes of miR-19b-3p.
We, for the first time, demonstrated that miR-19b-3p was involved in the proliferation, apoptosis and cycle of SH-SY5Y cells.
