CREB1-Induced lncRNA-9969 Selectively Binds miR-6361 Through Dual Seed-Structure Recognition in PV Interneurons
🧪 Overview
This hypothesis proposes that lncRNA-9969, when upregulated by CREB1 activation in parvalbumin (PV) interneurons, employs a sophisticated two-factor recognition mechanism to selectively sequester miR-6361 and enhance autophagy. The mechanism operates through canonical seed complementarity paired with favorable local RNA secondary structures that distinguish miR-6361 from other seed-sharing microRNAs. Upon gamma oscillation entrainment via transcranial focused ultrasound, PV interneurons undergo calcium influx leading to CREB1 phosphorylation at Ser133. This drives transcriptional upregulation of lncRNA-9969, which contains multiple miR-6361 binding sites characterized by both perfect seed complementarity and specific hairpin loop structures that create high-affinity binding pockets. The dual recognition system explains why lncRNA-9969 can function as an effective competing endogenous RNA (ceRNA) despite the presence of other microRNAs with overlapping seed sequences. Importantly, the local secondary structure requirement ensures that only miR-6361, among seed-sharing candidates, achieves sufficient binding affinity to be sequestered effectively.
