Input: Consider Input: Question: Is cDK10 a target for aberrant DNA methylation in breast cancer?
Answer: CDK10 is not a target for aberrant DNA methylation in breast cancer.

Output: no

Input: Consider Input: Question: Does expression microarray identify the unliganded glucocorticoid receptor as a regulator of gene expression in mammary epithelial cells?
Answer: This work presents the first identification of targets of unliganded GR. We propose that the balance between targets of liganded and unliganded GR signaling is responsible for controlling differentiation and apoptosis, respectively, and suggest that gene regulation by unliganded GR may represent a mechanism for reducing the risk of breast tumourigenesis by the elimination of abnormal cells.

Output: yes

Input: Consider Input: Question: Is the risk of atrial fibrillation after pneumonectomy impaired by preoperative administration of dexamethasone . A cohort study?
Answer: AF is a frequent complication after pneumonectomy associated with increased mortality. Whereas corticosteroids have been documented as preventing AF following cardiac surgery, no such effect was found after pneumonectomy.
Output: no
