Effects of inhibiting stearoyl-CoA desaturase (SCD) on the spatial transcriptome in a mouse model of Alzheimer's disease (AD)
Here, the effects of a stearoyl-CoA desaturase inhibitor (SCDi) on the mouse brain spatial transcriptome was investigated. More precisely, wild-type and 3xTg-AD female mice were infused in the brain left lateral ventricle with control (DMSO) or SCDi during 28 days (after the implantation of electrodes for electrocorticography and electromyography). Brains were sampled on the morning of Day 31 after the beginning of treatment, and immediately frozen. Brains were treated and libraries were prepared according to 10x Genomics protocols for Visium Spatial Gene Expression. Sequencing was conducted by Genome Quebec (Montreal, QC, Canada).
