| Annotation description: | Prickle1 (PK1) and Prickle2 (PK2) are involved in synapse formation and maintenance. Figure 1, S2: "To address whether PK1 and PK2 are also engaged in regulating the number of glutamatergic synapses in adulthood, we injected sgRNA viruses into the same brain regions of the Cre-dependent Cas9 mice at the age of 8 to 9 weeks. At 12 weeks, we found PK1 deletion led to an average of 41.5% reduction, and PK2 deletion resulted in an average of 57.5% reduction. Thus, PK1 and PK2 are critical not only for the assembly of glutamatergic synapses but also for their maintenance in adulthood. To examine whether PK1 and PK2 are functionally overlapping, we performed double knockout by injection of both the PK1 sgRNA virus and the PK2 sgRNA virus to the dorsal HPC and mPFC of the Cre-dependent Cas9 knock-in mice. Double knockout caused an average reduction of 72.5 and 75% during development and adulthood, respectively." These findings were confirmed using conditional knockouts in Figure 2. |
