| Model Scope | in_vitro |
| Model Type | in vitro 3D spheroid |
| Cell Lines Or Primary Cells | H1299 3D tumor spheroids |
| Animal Model | |
| Administration Route | |
| Output Type | Spheroid penetration and HIF-1α mRNA knockdown |
| Output Value | NNA penetrated spheroid core and produced greater HIF-1α knockdown than soluble ASO |
| Output Units | |
| Output Notes | 3D spheroid uptake was shown by confocal Z-stacks and flow cytometry; activity measured by RT-qPCR. |
| Toxicity Notes | No major toxicity emphasized for NNA scaffold; cell viability reduction relates to HIF-1α knockdown in cancer cells. |
