Erratum: Corrigendum Thymosin α-1 does not correct F508del-CFTR in cystic fibrosis airway epithelia (JCI Insight (2018) 3:3 (e98699) DOI: 10.1172/jci.insight.98699)

The unit for the concentration of peptide in the proliferation study was incorrectly reported in the Results and Methods sections and the Figure 4 legend. The corrected sentences, with sections indicated, are below. Results Evaluation of Tα-1 sequence and its effect on proliferation and apoptosis of MCF-7 breast cancer cells. Therefore, we plated MCF-7 at low density on 96-well plates suitable for confocal high-content imaging and evaluated cell proliferation for 72 hours following treatment with Tα-1 (100 μM) or scrambled peptide (100 μM). Methods Proliferation study. MCF-7 cells were plated at low density (10,000 cells/well) on 96-well plates suitable for high-content imaging. After 6 hours, cells were treated with the scrambled peptide (100 μM) or with Tα-1 (100 μM). Figure 4 legend (A) Dot plot showing proliferation of MCF-7 cells after 72-hour treatment with Tα-1 (100 μM) or scrambled peptide (100 μM, control). (B) Dot plot showing the number of apoptotic MCF-7 cells after 72-hour treatment with Tα-1 (100 μM) or scrambled peptide (100 μM, control). The article has been updated to reflect these changes. The authors regret the errors.
