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.
