Theta-Alpha Oscillation Entrainment Enhances lncRNA-9969-Mediated Mitochondrial Biogenesis Through SST Interneuron-Specific Epigenetic Networks
🧪 Overview
Molecular Mechanism and Rationale This therapeutic mechanism centers on a distinct circuit-RNA regulatory network that integrates theta-alpha oscillation dynamics (4-12 Hz) with mitochondrial biogenesis-mediated neuroprotection through somatostatin (SST) interneuron-specific long non-coding RNA networks. The hypothesis posits that closed-loop transcranial focused ultrasound (cl-tFUS) selectively activates hippocampal SST interneurons, which constitute approximately 30-35% of GABAergic interneurons and serve as primary generators of theta-alpha oscillations. Upon ultrasonic stimulation at theta frequencies, SST interneurons undergo sustained hyperpolarization-activated cyclic nucleotide-gated (HCN) channel activation, leading to rhythmic calcium oscillations and subsequent activation of CREB1 through calcineurin-mediated dephosphorylation pathways. CREB1 activation drives transcriptional upregulation of lncRNA-9969 through SST-specific enhancer regions containing CREB response elements.
