Task: Answer Verification
Input (English): Question: Does the transcription factor Ap-1 regulate monkey 20α-hydroxysteroid dehydrogenase promoter activity in CHO cells?
Answer: Our results indicate that the Ap-1 site (-281 → -274) (5'-TGTCTCAT-3') plays a crucial role in the activation of the monkey 20α-HSD gene. Thus, we demonstrated that monkey 20α-HSD promoter activity is regulated by the transcription factor Ap-1 in CHO-K1 cells.
Output (English): yes
