Background:

• Alpha-cyclodextrin/Moringin (α-CD/MOR) is an isothiocyanate with known neuroprotective and antioxidant effects.
• Understanding the molecular mechanisms underlying α-CD/MOR's action is crucial for its therapeutic development.

Purpose of the Study:

• To investigate the molecular pathways activated by prolonged α-CD/MOR treatment in a motor neuron cell line.
• To identify specific cellular components and biological processes affected by α-CD/MOR.

Main Methods:

• Differentiated NSC-34 motor neurons were treated with α-CD/MOR (0.5, 5, 10 μM) for 96 hours.
• Comparative transcriptomic analysis identified differentially expressed genes (DEGs).
• DEGs were mapped to synaptic genes using the SynGO database and analyzed for pathway enrichment (KEGG, SPIA).

Main Results:

• Prolonged α-CD/MOR treatment significantly modulated pathways related to synaptic organization and axon guidance.
• The KEGG pathway 'Regulation of actin cytoskeleton' was overrepresented, particularly at the highest dose.
• SPIA analysis confirmed activation of the actin cytoskeleton pathway.
• α-CD/MOR modulated transcription factors like Creb1, involved in synaptic plasticity.

Conclusions:

• α-CD/MOR influences synaptic functions and organization in motor neurons.
• The compound's effects are linked to the modulation of actin dynamics and synaptic plasticity.
• These findings highlight α-CD/MOR's potential in modulating neuronal structure and function.
