🔮 Falsifiable Predictions (2)

IF pharmacological activator of BMAL1/CLOCK heterodimers is administered to primary mouse microglia during inflammatory stimulation THEN a ~24-hour circadian oscillation in inflammatory gene expression (IL-1β, TNF-α, IL-6) will be restored AND peak cytokine levels will be suppressed by >50% compared
Predicted outcome: Restoration of rhythmic inflammatory gene expression with significant oscillation amplitude (>2-fold change between peak and trough) and reduced absol
Falsification: Inflammatory genes remain arrhythmic (no significant oscillation detected by cosinor analysis) OR cytokine levels are unchanged/increased compared to vehicle control, indicating BMAL1/CLOCK activation
