PSA promoter-driven CRISPR-dCas9-KRAB promotes the apoptosis of prostate cancer cells. A ELISA experiment results found that PSA-dCas9-KRAB significantly promoted the apoptosis of prostate cancer cells. B Flow cytometry analysis found that PSA-dCas9-KRAB significantly promoted the apoptosis of prostate cancer cells. **P < 0.01 (Student’s t-test, n = 3 replicates)
