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 δNp63α enhance the oncogenic phenotype of osteosarcoma cells by inducing the expression of GLI2?
Answer: Here, we report that GLI2 is the novel target gene of ΔNp63α and that ΔNp63α-GLI2 crosstalk in osteosarcoma cells is a necessary event in osteosarcoma progression. Defining the exact mechanisms involved in this interaction that mediate the pathogenesis of osteosarcoma promises to identify targets for drug therapy.
[EX A]: yes

[EX Q]: Question: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?

[EX A]: yes

[EX Q]: Question: Are cognitive-behavioral phenotypes of Williams syndrome associated with genetic variation in the GTF2I gene , in a healthy population?
