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 transcriptome analysis in oak uncover a strong impact of endogenous rhythmic growth on the interaction with plant-parasitic nematodes?
Answer: The results highlight that gene response patterns of plants to biotic interactions, both negative (i.e. plant-parasitic nematodes) and beneficial (i.e. mycorrhiza), are largely modulated by endogenous rhythmic growth, and that such plant traits should be considered as an important driver of these relationships in future studies.
[EX A]: yes

[EX Q]: Question: Does gPR39 activate proliferation and differentiation of porcine intramuscular preadipocytes through targeting the PI3K/AKT cell signaling pathway?
Answer: It indicated that GPR39 was a transducer of Zn(2+), and enhanced proliferation and differentiation of porcine intramuscular preadipocytes through activation of the PI3K/Akt signaling pathway.
[EX A]: yes

[EX Q]: Question: Is cXCR4 highly expressed at the tumor front but not in the center of prostate cancers?
Answer: CXCR4 seems overexpressed at the tumor front of prostate tumors, where it potentially promotes cell migration toward the SDF-1 centrifugal attracting gradient, as well as epithelial-mesenchymal transition. High CXCR4 and low SDF-1 levels at tumor front were both associated with adverse histological features.
[EX A]:
yes
