RETRACTED ARTICLE: Hypoxia-induced autophagy of stellate cells inhibits expression and secretion of lumican into microenvironment of pancreatic ductal adenocarcinoma (Cell Death & Differentiation, (2019), 26, 2, (382-393), 10.1038/s41418-018-0207-3)

Retraction to: Cell Death & Differentiationhttps://doi.org/10.1038/s41418-018-0207-3, published online 3 October 2018 The Editor in Chief has retracted this article. After publication, concerns were raised over the following issues: The HE staining images in Figs. 1A and 4A appear to partially overlap; the magnification seems to be different, but not the scale bars; In Figs. 2C and 3F, the HPSC b-actin bar appears to be very similar but the time stamps are different; The HIG-1 bands in Figs. 1E and 2E seem to partially overlap; they appear to be cropped differently. The HE staining images in Figs. 1A and 4A appear to partially overlap; the magnification seems to be different, but not the scale bars; In Figs. 2C and 3F, the HPSC b-actin bar appears to be very similar but the time stamps are different; The HIG-1 bands in Figs. 1E and 2E seem to partially overlap; they appear to be cropped differently. The authors did not provide the original images on request but stated that these issues were a result of mistakes. The Editor-in-Chief has, therefore, lost confidence in the integrity of the article’s findings. The authors did not state explicitly whether they agree to this retraction.
