Fig. 5From: Synthetic CRISPR/dCas9-KRAB system driven by specific PSA promoter suppresses malignant biological behavior of prostate cancer cells through negative feedback inhibition of PSA expressionPSA 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)Back to article page
