Table 4. Protein and gene expression of transient receptor potential ankyrin 1 and transient receptor potential vanilloid 4 in normal and knee osteoarthritis groups.
Group (n=15) | TRPA1 (protein) | TRPV41 (protein) | TRPA1 (mRNA) | TRPV4 (mRNA) |
Mean±SEM | Mean±SEM | Mean±SEM | Mean±SEM | |
Normal | 0.138±0.071 | 0.494±0.074 | 1.020±0.237 | 1.058±0.089 |
Knee osteoarthritis | 0.560±0.283** | 0.729±0.130** | 4.418±1.886** | 3.679±0.754** |
SEM: Standard error of the mean; * p<0.05, ** p<0.01, compared with normal group; TRPA1: Transient receptor potential ankyrin 1; TRPV4: Transient receptor potential vanilloid 4; mRNA: Messenger ribonucleic acid. |
