| Prediction | Predicted | Observed | Status | Conf |
|---|---|---|---|---|
| IF SIRT3 is pharmacologically activated (e.g., with SIRT3 agonist CP-473041) in primary cortical neurons during metabolic stress (20h glucose deprivation), THEN hub neurons identified by viral labelin | Hub neurons will maintain higher ΔΨm (25-40% improvement) relative to non-hub neurons following SIRT3 activation under metabolic stress | — no observation — | pending | 0.45 |
| IF SIRT3 is knocked down using CRISPR interference (sgSIRT3) specifically in hub neurons in vivo, THEN hub neurons in the mouse medial prefrontal cortex will show accelerated dysfunction under chronic | SIRT3 knockdown in hub neurons will cause 40-60% reduction in hub neuron survival and 25-35% reduction in hub-hub functional connectivity | — no observation — | pending | 0.38 |
