This article has been retracted at the request of the authors, because they found that beta-actin, as the loading control, did not match with SOCS2, as shown in Fig. 7, depicting western blot for SOCS2 protein. The authors therefore request that the paper be retracted, although this result was unintentional and the conclusions in this paper hold valid.
