🔮 Falsifiable Predictions (2)
pendingconf 55%
IF we administer HMGCS2 agonists (e.g., novel synthetic compounds targeting mitochondrial HMGCS2) to 5xFAD transgenic mice starting at 3 months of age for 6 months, THEN we will observe significantly reduced amyloid plaque burden and improved performance on Morris water maze (≥20% latency reduction)
Predicted outcome: ≥20% reduction in amyloid plaque density and ≥15% improvement in spatial memory retention versus vehicle controls
Falsification: No significant difference in amyloid burden, cognitive performance, or ketone production between HMGCS2 agonist and vehicle groups (p>0.05); OR increased neuronal death/motor dysfunction in treatment

IF we stratify early-stage Alzheimer's disease patients (CDR 0.5-1.0) by baseline HMGCS2 expression in peripheral blood mononuclear cells (qPCR) and follow them for 24 months, THEN patients in the high HMGCS2 expression tertile will demonstrate slower decline on composite cognitive scores (ADAS-Cog1
Predicted outcome: ≥30% slower annual decline in ADAS-Cog13 and ≥25% reduced hippocampal volume loss in high vs. low HMGCS2 expression groups
Falsification: No significant correlation between baseline HMGCS2 expression and 24-month cognitive/structural decline (p>0.05); OR higher HMGCS2 associated with faster decline
