Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

[EX Q]: 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.
[EX A]: yes

[EX Q]: Question: Does oxidative status in the macula densa modulate tubuloglomerular feedback responsiveness in angiotensin II-induced hypertension?
Answer: Under physiological conditions, TGF response is mainly controlled by the NO generated in the macula densa; in Ang II induced hypertension, the TGF response is mainly controlled by the O2- generated by the macula densa.
[EX A]: yes

[EX Q]: Question: Are lipid levels in HIV-positive men receiving anti-retroviral therapy associated with copy number variation of reverse cholesterol transport pathway genes?
Answer: Whole gene CNV is uncommon in RCT pathway genes, and not a major factor in the development of highly active antiretroviral therapy (HAART) associated dyslipidemia.
[EX A]:
no
