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: Is cytoglobin upregulated by tumour hypoxia and silenced by promoter hypermethylation in head and neck cancer?
Answer: We conclude that the CYGB gene is regulated by both promoter methylation and tumour hypoxia in HNSCC and that increased expression of this gene correlates with clincopathological measures of a tumour's biological aggression.
[A]: yes


[Q]: Question: Does combination of dehydroepiandrosterone and orthovanadate administration reduce intestinal leukocyte recruitment in models of experimental sepsis?
Answer: Our results indicate that DHEA is able to reduce intestinal leukocyte recruitment induced by experimental sepsis. Combination of DHEA with OV inhibits leukocyte adherence to intestinal endothelium, similar to what is achieved by the single administration of DHEA but with significantly improved FCD. These findings suggest a potential role for DHEA and OV in clinical sepsis.
[A]: yes


[Q]: Question: Is gOLP3 a predictor of survival in patients with hepatocellular carcinoma?
Answer: GOLPH3 was overexpressed in HCC at both the mRNA and protein levels, and the presence of high levels of expression of GOLPH3 could serve as a novel and potential prognostic biomarker for liver cancer patients.
[A]:
yes
