Correction to: Scientific Reports https://doi.org/10.1038/s41598-019-50380-0, published online 27 September 2019


This article contains an error in Figure 5, where panel ‘PNA-30/HepG2 Day 7’ is a duplication of panel ‘PNA-0/HepG2 Day 14’, and ‘PNA-10/HepG2 Day 14’ is a duplication of ‘PNA-50/HepG2 Day 1’.


The corrected Figure 5 and its accompanying legend appear below:
