Retraction

The article entitled “Targeting PI3KC2β impairs proliferation and survival in acute leukemia, brain tumours and neuroendocrine tumours” by Boller et al. published in Anticancer Research 32(8): 3015-3027, 2012 is retracted due to the similarity of Figure 2C with Figure 1A of the article published in Clinical Cancer Research 14(4): 1172-1181, 2008. Efforts of the Editorial Office of Anticancer Research to communicate with the Authors were unsuccessful.
