Unfortunately, after publication, we found that the image in Figure 5a of the above article [1] is identical to the image from Figure 6a, which is due to an inadvertent replacement during the final submission of figures for the publication of the article. The published version of Figure 5a is therefore incorrect. The corrected version of the Figure 5 is shown below. The only change is in the panel of Figure 5a. The rest of the figure is identical to the published version. We traced back our original data and found that the analysis of the data and the conclusion were not influenced.

Cx26-composed GJIC increases intracellular Ca2+ release after PDT. The cells were treated with Dox or GJIC inhibitor, 18α-GA, incubated with Fluo-3-Am and irradiated with or without 1 μg/mL Photofrin in Ca2+- free BBS. After irradiation, the fluorescence intensity of Ca2+ was detected using flow cytometry. A: control; B: 1 μg/mL Photofrin; C: The fluorescence intensity of Ca2+. The data in different groups were expressed as the mean ± SD from 3 experiments. Statistical difference between groups was assessed by one way ANOVA using SPSS 20.0. *: P < 0.05,**: P < 0.01, significantly different from control group (Dox-treated); #: P < 0.05, significantly different from control group (Dox-untreated); ※※: P < 0.01, significantly different from Photofrin group (Dox-treated)
