In Figure 5 in the paper titled “Synergistic Effects of Toxic Elements on Heat Shock Proteins,” we cited wrong reference, K. S. Ali, L. Dorgai, M. Ábrahám, and E. Hermesz, “Tissue- and stressor-specific differential expression of two hsc70 genes in carp,” Biochemical and Biophysical Research Communications, vol. 307, no. 3, pp. 503–509, 2003. The correct citation of Figure 5 is “A. Ali, P. H. Krone, D. S. Pearson and J. J. Heikkila “Evaluation of stress-inducible hsp90 gene expression as a potential molecular biomarker in xenopus laevis,” Cell Stress and Chaperones, vol. 1, no. 1, pp. 62–69, 1996.”
