In the original publication, the word “Cystine” was mistakenly misspelled as “Cysteine”. The corrected versions are given below.

In the abbreviations: Cystine instead of Cysteine.

In page 24, line 5 of paragraph “IDH wt glioma cells release Glu” should read as follows: “When intracellular Glu levels rise, excessive Glu is released via the glutamine/cystine antiporter System x c (extensively reviewed by Lewerenz et al. 2013) in exchange for cystine (Cys; Fig. 3).

In page 25, the section title should read as follows: “Methionine–Cystine double deprivation increases ROS levels in glioma cells”.
