Effects of attenuating astrocytic Ca2+ activity in the medial prefrontal cortex with iβARK on transcriptional profiles in 5xFAD mice

GSE283790 Mus musculus Expression profiling by high throughput sequencing 25 samples 2026/02/12 GPL24247
Summary
We injected adeno-associated viruses (AAV2/5) carrying an inhibitory peptide derived from β-adrenergic receptor kinase 1 (iβARK), tagged with mCherry for identification, into the medial prefrontal cortex (mPFC) of 5xFAD mice. This strategy aimed to attenuate Gq GPCR-induced Ca2+ activity in astrocytes. In the control group, mice were injected with AAV2/5 expressing only mCherry. Subsequently, RNA sequencing analysis was conducted on the mPFC tissue samples from these mice, enabling a comparative assessment of transcriptomic alterations and an exploration of the potential implications resulting from the modulation of Gq-GPCR signaling.
