CPD10-interacting GRK2 (lanes 3 and 4; left) was eluted from the CPD10-containing affinity matrix and detected by immunoblot (IB). TOMM6 did not interact and was below detection limit (lanes 3 and 4; right). Lanes 1 and 2 show a control affinity matrix (AP: Con). (B) Enrichment of p-S670-GRK2(K220R) (lanes 7 and 8; left) and co-enrichment of TOMM6 (lanes 7 and 8; right) by CPD10 ligand affinity chromatography (AP:C10) from brains from 12-month-old Tg2576- GRK2K220R mice.

The S670 phosphorylation is shown in green (CPK model). Right panels show the docking site of CPD10 in the large lobe of GRK2 (upper) and in the ATP-binding site of p-S670-GRK2 (middle). (F) Binding energies (kcal/mol) of CPD10 (S-isomer) docking to GRK2 and phospho-S670-GRK2. Data are mean of top five poses ± SD: −389.1 ± 12.1; +40.3 ± 32.7; −81.2 ± 30.3. (G) IC 50 values of CPD10 for inhibition of TOMM6 phosphorylation by p-S670-GRK2 and GRK2-S670A (S670A). Data are mean ± SD; n = 4 independent experiments with four technical replicates each. (H) CPD10 (10 μM) did not substantially inhibit GRK2-related kinases. (I) Conceptual model and molecular dynamics simulation of GRK2 function modulation by CPD10. CPD10 could stabilize the GRK2 monomer (cyan, right) and prevent phospho-S670-GRK2 and TOMM6 aggregation (left); OMM: outer mitochondrial membrane; IMS: intermembrane space. Potential energies (E) of GRK2 (lower right) and phospho-S670-GRK2 (p-S670; lower left) without (w/o) and with CPD10 (+C10) interaction are given after energy minimization without (w/o MD sim) and with MD simulation (MD sim).

Data are mean ± SD ( n = 6 mice per group); unpaired, two-tailed t test; df = 10; t = 12.73, 13.34 (M); 4.822, 3.117 (N). (O) Proteasome activities of brains from 18-month-old Tg2576 (AD) mice after 6 months of treatment with the indicated doses of CPD57. (P) Contents of insoluble Aβ1-40 in brains of 18-month-old Tg2576 (AD) mice after 6 months of treatment with the indicated doses of CPD57. (O and P) Data are mean ± SD ( n = 6 mice per group); one-way ANOVA and Tukey’s test; F(3,20) = 34.26 (Suc-LLVY-AMC), 32.49 (Boc-LRR-AMC), 27.87 (Z-LLE-AMC), 40.90 (P). See also .

    Intrathoracic ABE treatment corrects Tnni3 R193H mutation in cardiac tissue (A and B) Schematic illustration of the dual AAV9 vector construction strategy and ABE treatment, administered via intrathoracic injections in 6-week-old Tnni3 R193H/R193H mice. (C and D) Efficient correction of Tnni3 mutation in the heart. Assessment of gene editing efficiency in the hearts of Tnni3 R193H/R193H mice 12 weeks after the AAV treatment. A>G editing efficiencies were measured in genomic DNA and mRNA using high-throughput sequencing. Each point represents an individual mouse. ∗∗∗∗ p < 0.0001 based on Student’s unpaired t test analysis. Data are presented as mean ± SEM. (E and F) Lack of liver editing following the AAV9-ABE treatment. As in (C), gene editing efficiency in the livers of Tnni3 R193H/R193H mice after 12 weeks of dual AAV treatment. A>G editing efficiency was also assessed in the genomic DNA and mRNA extracted from liver tissue, demonstrating diminished delivery and expression of the ABE system in the hepatic tissue. Each point represents an individual mouse. ns, not statistically significant (Student’s unpaired t test analysis). Data are presented as mean ± SEM.
