[HTML][HTML] Aberrant RNA translation in fragile X syndrome: From FMRP mechanisms to emerging therapeutic strategies

A Banerjee, MF Ifrim, AN Valdez, N Raj, GJ Bassell - Brain research, 2018 - Elsevier
Research in the past decades has unfolded the multifaceted role of Fragile X mental
retardation protein (FMRP) and how its absence contributes to the pathophysiology of Fragile X …

Single-molecule imaging of PSD-95 mRNA translation in dendrites and its dysregulation in a mouse model of fragile X syndrome

MF Ifrim, KR Williams, GJ Bassell - Journal of Neuroscience, 2015 - Soc Neuroscience
Fragile X syndrome (FXS) is caused by the loss of the fragile X mental retardation protein (FMRP),
an RNA binding protein that regulates translation of numerous target mRNAs, some of …

A native function for RAN translation and CGG repeats in regulating fragile X protein synthesis

…, JM Haenfler, BN Flores, Y Liu, MF Ifrim… - Nature …, 2020 - nature.com
Repeat-associated non-AUG-initiated translation of expanded CGG repeats (CGG RAN)

MF Ifrim, A Janusz-Kaminska, GJ Bassell - Cell reports, 2022 - cell.com
The ubiquitination/proteasome system is important for the spatiotemporal control of protein
synthesis and degradation at synapses, while dysregulation may underlie autism spectrum …

A 3′ untranslated region variant in FMR1 eliminates neuronal activity-dependent translation of FMRP by disrupting binding of the RNA-binding protein HuR

…, BR Anderson, MF Ifrim… - Proceedings of the …, 2015 - National Acad Sciences

[HTML][HTML] Conditional knockout of tumor overexpressed gene in mouse neurons affects RNA granule assembly, granule translation, LTP and short term habituation

E Barbarese, MF Ifrim, L Hsieh, C Guo, V Tatavarty… - PloS one, 2013 - journals.plos.org
In neurons, specific RNAs are assembled into granules, which are translated in dendrites,
however the functional consequences of granule assembly are not known. Tumor …
