Input: Question: Does a Her2-let-7-2-AR circuit affect prognosis in patients with Her2-positive breast cancer?
Answer: The mutual and reciprocal interaction between Her2, 2-AR, and let-7f may maintain a high level of 2-AR in breast cancer cells. Our data suggest that 2-AR may be a new useful biomarker for predicting prognosis in Her2-positive breast cancer and may also be a promising selective therapeutic target for the aggressive subtype of breast cancer.
Output:
yes
