Author Correction Differential action of steroid hormones on human endothelium Hans Oberleithner, Christoph Riethmüller, Thomas Ludwig, Victor Shahin, Christian Stock, Albrecht Schwab, Martin Hausberg, Kristina Kusche and Hermann Schillers Journal of Cell Science 120, 2467 (2007) doi:10.1242/jcs.017467 There was an error published in J. Cell Sci. 119, 1926-1932. A labelling error occurred in Fig. 5, showing a western blot with incorrect kDa values. The correct Fig. 5 is shown below. Fig. 5. Identification of ENaC in human endothelial cells (HUVEC; representative experiment). Membrane proteins were separated by SDS- PAGE and stained with Coomassie brilliant blue (lane 1). ENaC was detected by using an anti-ENaC antibody (lanes 2-4). The amount of ENaC in the aldosterone-treated sample (A) is about twice that in the control (C) and about six times higher than that of aldosterone and spironolactone (A+S)-incubated HUVEC. As positive control (PC), we used ENaC-expressing oocytes. The molecular mass standard is given on the left. The upper band in the range of 95 kDa most likely represents a glycosylated form of ENaC. Owing to the labelling error, a sentence in the Results section (p. 1928, right column) refers to the incorrect kDa values: The ENaC antibody recognises a specific band with an apparent molecular mass of about 67 kDa (Fig. 5), which is the same as that reported for the ENaC subunit (Hughey et al., 2003). The correct sentence is given below: The ENaC antibody recognises a specific band with an apparent molecular mass of about 95 kDa and a second band of about 55 kDa (Fig. 5), which is the same as that reported for the ENaC subunit (Hughey et al., 2003).
