It has come to our attention that errors were made in measurements of resting blood pressure reported in this article, in Fig. 8 and in the ‘Results’ section entitled ‘Deficiency of baroreceptor function in Trpc5 knockout (Trpc5−/−) mice’. Two of the twelve measurements for Trpc5−/− mice exceeded physiologically realistic values (277.3 and 390.5 mm Hg), and we assume were a result of technical errors in blood pressure recording. Upon removal of these two outliers and their corresponding control measurements, and replacement with resting blood pressure measurements from two additional pairs of mice, we no longer find a statistically significant difference in the resting mean arterial pressure between Trpc5−/− and wild-type mice (121±8 mm Hg, n=12 for Trpc5−/−mice versus 105±4 mm Hg, n=12 for wild-type mice, P>0.05 by Student’s t-test). We can therefore no longer conclude that Trpc5 knockout increases basal blood pressure. However, a statistically significant difference in range of blood pressure variation over 24 h remains (60±6 mm Hg, n=12 for wild-type mice and 114±22 mm Hg, n=12 for Trpc5−/− mice, P<0.05 by Student’s t-test). These errors therefore do not affect our conclusion that Trpc5 knockout results in blood pressure instability.
An updated version of Fig. 8d, which includes the above data, is presented below as Fig. 1. The error has not been corrected in the original version of the Article. Furthermore all resting mean arterial blood pressure data from the two mouse cohorts are presented as Supplementary Data 1 associated with this Author Correction.
