IF LTN1 is pharmacologically inhibited (via CB-5083 or equivalent proteasome inhibitor) in patient-derived iPSC neurons carrying pathogenic polyglutamine repeats, THEN nascent seed-templated proteins accumulate within 48 hours, measurable by flow cytometry with ubiquitin-specific antibodies and nasc
Predicted outcome: 2-fold or greater increase in ubiquitylated nascent protein aggregates in LTN1-inhibited neurons versus vehicle control, detectable by high-content im
Falsification: No significant increase in nascent protein aggregation (<1.2-fold change, p>0.05) despite >80% LTN1 knockdown verified by qPCR; any observed aggregates are not nascent (negative for S35 incorporation)

IF Ltn1 is genetically ablated in 5xFAD amyloidogenic mice using CRISPR-Cas9, THEN behavioral deficits (measured by Morris water maze and contextual fear conditioning) worsen by 15% or more and cerebral amyloid burden increases by 20% or more by 6 months of age, compared to 5xFAD;Ltn1+/+ littermates
Predicted outcome: Ltn1-/-;5xFAD mice exhibit significant cognitive decline (escape latency >40 seconds vs <30 seconds in controls) and elevated insoluble Aβ42 (ELISA) i
Falsification: No difference in amyloid plaque density (Thioflavin-S quantification) or behavioral performance between Ltn1-/- and Ltn1+/+ mice in 5xFAD background (p>0.1); any cognitive decline is not attributable
