This article has been withdrawn by the authors. After reviewing the data, the authors informed the journal of several issues in their article. The modifications include the following. The CIITA immunoblots from Fig. 3, C and D, were duplicated. The GAPDH immunoblot from Fig. 3C was reused as β-actin in Fig. 6E. The GAPDH immunoblots in Fig. 5I were reused in Fig. 6F. The p-p38 immunoblot from Fig. 6C was reused as CIITA in Fig. 6E and H3K9me2/3 in Fig. 6F. In Fig. 6F, the first two lanes of the CIITA immunoblot on the left were reused in lanes 2 and 3 of the CIITA immunoblot on the right. As these figures were not prepared according to the publication policy of the journal, the authors wish to withdraw this article and sincerely apologize to the readers.
