Task: Answer Verification
Input (English): Question: Is transient receptor potential ankyrin 1 ( TRPA1 ) functionally expressed in primary human osteoarthritic chondrocytes?
Answer: The TRPA1 cation channel was found to be functionally expressed in primary human OA chondrocytes, which is an original finding. The presence and inflammatory and catabolic effects of TRPA1 in human OA chondrocytes propose a highly intriguing role for TRPA1 as a pathogenic factor and drug target in OA.
Output (English): yes
