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 variation in the gene for human peroxisome proliferator activated receptor gamma ( PPARgamma ) play a major role in the development of morbid obesity?
Answer: Variation in the PPARgamma gene is unlikely to play a major role in the development of morbid obesity.

A: no

Q: Question: Does selective pharmacological blockade of the TRPV1 receptor suppress sensory reflexes of the rodent bladder?
Answer: The TRPV1 antagonists JNJ17203212 and JYL1421 increased the threshold for activation of the micturition reflex in the anesthetized rat volume induced micturition reflex model. This effect appeared to be mediated by capsaicin sensitive afferents. JNJ17203212 also inhibited detrusor overactivity induced by intravesical capsaicin and intravesical citric acid. These data extend our understanding of the role of TRPV1 in sensory modulation of the micturition reflex under nonirritant and inflammatory conditions.

A:
yes
