Correction to: Gastric Cancer https://doi.org/10.1007/s10120-019-01010-1

We recently published the priming effect of a DNA demethylating agent in chemotherapy of gastric cancer (original article). Unfortunately, there are errors in the units of some panels in Fig. 2. The units for SN38 (the most upper three panels) and PTX (the second bottom two panels) should be “nM”, instead of “µM”.

The errors were produced when the unit for 5-FU (the two bottom panels) was corrected from “nM” to “µM” during the production stage. Accidentally, the units for SN38 and PTX were also changed. A correct Fig. 2 is shown below.

The publisher sincerely apologize for the error.

Effect of epigenetic priming by 5-aza-dC. Resistant cells were first treated with 5-aza-dC or mock first, and subsequently treated with a cytotoxic drug. The IC50 values were significantly lower for SN38 and CDDP, but not for PTX and 5-FU
