Research Question¶
The study demonstrates direct binding between lncRNA-0021 and miR-6361 as the key ceRNA mechanism, but doesn't explain the molecular basis for this specific interaction. Understanding binding specificity is crucial for designing targeted RNA therapeutics and predicting off-target effects.
