An early meeting abstract reported increased bladder contractions in mouse and rat by a non‐specific TRPV4 activator and proposed an interesting idea that TRPV4 contributes to bladder overactivity.81 However, this was a simple contraction of normal bladder tissue and bladder overactivity was not substantiated, and no human tissue or pathological overactive bladder was examined. The gene discussed is TRPV4; the disease is overactive bladder.
