Detailed Instructions: 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.
Q: Question: Does dBD-F induce apoptosis in gastric cancer-derived cells through suppressing HIF2 expression?
Answer: From our findings we conclude that DBD-F (i) is cytotoxic to gastric cancer-derived cells and (ii) can induce apoptosis in these cells via the MEK/ERK signaling pathway. In addition, our findings strongly indicate that DBD-F can inhibit HIF2 expression by affecting the phosphorylation status of MEK/ERK in gastric cancer-derived cells.
A:
yes
