 A corrigendum on A Novel Role of Connexin 40-Formed Channels in the Enhanced Efficacy of Photodynamic Therapy By Deng-Pan Wu, Li-Ru Bai, Yan-Fang Lv, Yan Zhou, Chun-Hui Ding, Si-Man Yang, Fan Zhang, Yuan-Yuan Wang, Jin-Lan Huang, Xiao-Xing Yin (2019).

In the original article, there was a mistake in Figure 5 as published. After confirmation, we found that the representative images of the flow cytometer of Dox-untreated and Dox-treated control group (panel A) and Photofrin group (panel E) in Figure 5 were misused due to our carelessness in the selection of representative images for image combination using software of flow cytometer. The corrected Figure 5 appears below.

Ca2+ release and influx were increased by Cx40-formed channels. After incubation with Fluo-3-Am, Dox-treated and Dox-untreated cells were irradiated with or without Photofrin. Flow cytometry was performed to measure the fluorescence intensity of Ca2+ after PDT. (A) control; (B) 2.5mg/mL Photofrin; (C) The fluorescence intensity of Ca2+. For (A–C), the cells were incubated in fresh BBS in the absence of Ca2+ during irradiation. (D) control; (E) 2.5mg/mL Photofrin; (F) The fluorescence intensity of Ca2+. For (D–F), the cells were incubated in fresh BBS in the presence of Ca2+ during irradiation. Data points are mean ± SD from 3 experiments. t test was used to assess statistically significant differences between groups. *P < 0.05, **P < 0.01, significantly different from Dox-untreated group.
