While we had intended that these papers offered different research perspectives, we were reminded of the fact that, in submitting the article to International Journal of Molecular Medicine, the work described therein was required to be “original research that has not been published previously, and is not under consideration for publication elsewhere, in whole or in part”. Therefore, owing to the redundancy in the data between these publications, the above paper is to be retracted. All the authors have agreed to the retraction. We sincerely apologize for our misunderstanding, and deeply regret any inconvenience this mistake has caused.
