Definition: 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.
Input: Question: Does nitric oxide inhibit IFN regulatory factor 1 and nuclear factor-kappaB pathways in rhinovirus-infected epithelial cells?
Answer: Nitric oxide blocks rhinovirus-mediated activation and nuclear translocation of both NF-kappaB and IRF-1. NO also directly inhibits the binding of each of these transcription factors to their respective recognition sites in the CXCL10 promoter. In addition, the ability of HRV-16 to induce epithelial expression of IRF-1 is dependent, at least in part, on viral activation of NF-kappaB.
Output:
yes
