PSA promoter-driven CRISPR-dCas9-KRAB suppresses the colony-forming ability and transwell transmembrane migration ability of prostate cancer cells. A The colony formation assay revealed that PSA-dCas9-KRAB significantly inhibited the colony-forming ability of prostate cancer cells. B Transwell assay revealed that PSA-dCas9-KRAB significantly inhibited the migration number of prostate cancer cells. **P < 0.01 (Student’s t-test, n = 3 replicates)
