Correction to: Acta Pharmacologica Sinica https://doi.org/10.1038/s41401-019-0268-y, published online 17 July 2019

The authors are very sorry for two inadvertent mistakes in the figures: the images of immunoblot showing PDEδ expression and the corresponding GAPDH loading control in H1792 and H441 cells in Fig. 2a were provided incorrectly. These errors were made due to our carelessness during the stage of figure preparation.

The conclusion of the original article or the context of the article was not affected. The corrected figures are presented as follows. The authors deeply apologize for any inconvenience caused to the journal and readers.

It should read:

Fig. 2a KRAS mutant cell viability upon PDEδ depletion. KRAS-dependent cells were treated with PDEδ siRNAs (siPDE6D #1, #2) for 96 h. Cell viability was measured by crystal violet staining assay (upper panel). siRNA interference efficiency was measured by immunoblotting (lower panel). The error bars represent the mean ± SD of four replicates. *P < 0.05; **P < 0.01; ***P < 0.001, n.s., not significant.
