Correction: Betaine is accumulated via transient choline dehydrogenase activation during mouse oocyte meiotic maturation (Journal of Biological Chemistry (2017) 292 (13784-13794) DOI: 10.1074/jbc.M117.803080)

Abstract

The authors recently became aware that the measurements reported in Fig. 7 had been provided to the authors with the incorrect units stated. The units stated by the laboratory that had been contracted to do the measurements were ng/ml (in 200 μl of sample), whereas the actual units for the values that were provided were total pmoles in each sample. This resulted in the calculated amounts of betaine per oocyte that were reported (in pmoles/oocyte) in Fig. 7 being approximately 48% higher than the amounts calculated using the correct units. This error did not affect the betaine measurements reported in Fig. 1, which were done in a different laboratory. Fig. 7 has been revised to show the corrected amounts of betaine, and the y axis ranges have been adjusted accordingly. The error does not affect the statistical analyses or the conclusions of the article in any way. The authors regret any inconvenience this error may have caused.
