PTEN -siRNA nanoparticle transfection enables efficient gene silencing with minimal impact on neuron health (A) PTEN -siRNA nanoparticles (100 nM) demonstrated highly efficient knockdown of target PTEN mRNA in differentiated <t>NSC34</t> neurons, with peak knockdown on Day 3 for the delivered siRNA [t(2) = −4.840, p = 0.02007; one-tailed] with expression levels returning to baseline by Day 7 [t(2) = 0.05373, p = 0.5190; one-tailed]. RNA fold change and associated error was assessed using the 2 −ΔΔCt method and normalized to GAPDH as per (B) Treatment of neurons with PTEN- siRNA nanoparticles at 100 nM had a non-significant effect on the metabolic activity at 3 [t(2) = 0.6370, p = 0.5893, 95 % CI 74.4820<x <134.3874] and 7 days [t(2) = −3.390, p = 0.07708, 95 % CI -66.21<x<104.0] post-transfection. (C – F) Transfection of PTEN -siRNA nanoparticles does not affect neuronal morphology. Control and PTEN -siRNA nanoparticle treated neurons have a similar distribution, density, and morphology compared to control neurons (C, D). Higher magnification images showed that all neurons (control and treated) possessed a typical neuronal morphology with several neurites extending from each cell body (E, F). All cells were stained for F-actin (green = phalloidin) and nuclei (blue = DAPI). Scale Bar in (C, D): 100 μm; Scale Bar in (E, F): 50 μm.

Article Snippet: NSC34 neuronal culture and transfections: NSC34 neurons (Cedarlane Cat No. CLU140), a hybrid cell line produced by the fusion of motor neuron enriched embryonic mouse spinal cord cells with mouse neuroblastoma cells, were cultured in growth medium Dulbecco's Modified Eagle Medium (DMEM; Sigma-Aldrich, Ireland) supplemented with 10 % fetal bovine serum (FBS; Labtech UK), 1 % (v/v) L-Glutamine (Sigma-Aldrich, Ireland), and 1 % (v/v) Penicillin- Streptomycin Solution (Sigma-Aldrich, Ireland) in a T-175 cell culture flask (37 °C, 5 % CO 2 ).

Scaffold-mediated siRNA delivery does not affect the viability of neurons, results in prolonged downregulation of PTEN, and stimulates increased expression of BCL2 and GAP43 mRNA . (A) The metabolic activity of NSC34 neurons cultured on PTEN -siRNA activated scaffolds peaked by day 3 post-transfection [t(2) = 4.0599, p = 0.05565, 95 % CI 93.954<x<308.3], decreased by day 7 [t(2) = −15.068, p = 0.004375, 95 % CI 49.7157<x<72.05] and was similar to control levels by day 21 [t(2) = −0.1042, p = 0.9265, 95 % CI 83.23<x<116.0]. Metabolic activity normalization was performed relative to the untreated cells. (B) LDH assay revealed a consistent but small increase in cell stress over a span of 21 days. (C – D) Analysis of PTEN gene expression in scaffold transfected neurons over 21 days showed a significant decrease in expression levels [t(4) = −3.2927, p = 0.01507; one-tailed] 3 days after transfection that was then followed by a gradual return toward untreated control levels denoted by the blue regression line which approaches the red untreated control line after 21 days. (E – F) The change in BCL2 expression 3-, 7-, and 21-days post-transfection showed a significant initial elevation [t(4) = 2.092, p = 0.05227, one-tailed], followed by a gradual reduction converging toward untreated control levels. (G – H). Similarly, GAP43 expression was characterised by of an initial significant rise [t(4) = 2.1748, p = 0.04765, one-tailed] in levels that was followed by a decrease over the 21-day culture period.
