Just ask a group of Spanish researchers who published a 2011 paper in Proteome Science, then lost it this past April because they’d stolen text and a figure from previously published work — some, but not all of it, their own.
The retraction notice for “Clinical and technical phosphoproteomic research” tells the story:
This article  has been regretfully retracted by the Editors because of significant overlap with a figure and text from previously published articles [2-4]. We apologise to all affected parties for the inconvenience caused.
