RETRACTED: Apoptosis of CT26 colorectal cancer cells induced by Clostridium difficile toxin A stimulates potent anti-tumor immunity

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Authors.After extensive discussions with the lead author and several coworkers, the authors concluded that several experimental results, especially results regarding toxin-induced apoptosis and dendritic cell maturation, need further repeats before the authors can make final conclusions. The authors therefore believe that the article published in its current form is too preliminary and potentially misleading to BBRC readers in this field and would like to apologize for this error.
