Hypothesis
Transcriptome-wide competition determines functional selectivity after direct binding is established
lncRNA-0021 may not be uniquely specific at the physical binding level; instead, its apparent selectivity for mmu-miR-6361 could emerge from stoichiometry, transcript abundance, and superior free energy relative to other cellular decoys.

🧪 Overview
lncRNA-0021 may not be uniquely specific at the physical binding level; instead, its apparent selectivity for mmu-miR-6361 could emerge from stoichiometry, transcript abundance, and superior free energy relative to other cellular decoys. This is best viewed as a functional-selectivity hypothesis that modulates the impact of binding rather than fully explaining the molecular recognition event itself.

⚖️ Evidence Matrix3 supports2 contradicts
Supports
ceRNA crosstalk depends on relative abundance and affinity across competing transcripts rather than single-pair binding alone.
Supports
High-affinity lncRNA sponges can dominate miRNA sequestration under favorable stoichiometric conditions.
Supports
Exosomal lncRNAs can achieve concentrations compatible with competitive effects in recipient cells.
Contradicts
This addresses network-level functional selectivity, not the molecular basis of how lncRNA-0021 physically recognizes mmu-miR-6361.
Contradicts
Quantitative ceRNA effects are often weak or controversial in physiological settings.

IF we transfect synthetic decoy RNAs with comparable binding affinity for mmu-miR-6361 at equimolar or higher concentrations than lncRNA-0021 in mouse hippocampal neurons, THEN the functional impact of lncRNA-0021 on mmu-miR-6361 target gene expression will be significantly reduced (≥40% attenuation
Predicted outcome: Reduction in lncRNA-0021-mediated repression of mmu-miR-6361 targets (e.g., predicted target genes from ArrayExpress E-MTAB-XXXX or similar transcript
Falsification: lncRNA-0021 maintains equivalent functional selectivity on mmu-miR-6361 targets even when synthetic decoys are present at 5-fold excess, indicating that binding affinity alone does not determine funct

IF we simultaneously knockdown lncRNA-0021 and six predicted competing decoy transcripts (identified by transcriptome-wide free energy ranking) in mouse cortical neurons, THEN the phenotypic impact on mmu-miR-6361 activity will not differ significantly from lncRNA-0021 knockdown alone within 72 hour
Predicted outcome: No additional change in mmu-miR-6361 target expression or downstream neuronal phenotypic markers (e.g., neuronal viability, dendritic complexity marke
Falsification: Combined knockdown of lncRNA-0021 plus competing decoys produces significantly stronger phenotype (e.g., ≥30% difference in target repression) than lncRNA-0021 knockdown alone, indicating that lncRNA-
