In the current study, the researchers show that Sirt3 knockout mice have decreased MnSOD activity despite normal levels of protein.Gius and colleagues determined that the MnSOD was altered in abnormal Sirt3 knockout mice at a specific amino acid tamoxifen for men http://www.nolvadex.biz .This anomalous MnSOD modification reduces the ability of the enzyme, To detoxify superoxide and appeared to to increase ROS in Sirt3 knockout mouse tumors explain. – These results suggest that aberrant regulation of MnSOD plays a role in receptor-positive breast cancer, said Gius. – Gius and colleagues to also even an antibody that can check the status of acetylation of MnSOD, which he says are used potentially screening breast tissue samples, which are a risk to women for the recurrence of cancer or assess due to developed this dysregulation of MnSOD. .
Previously, while the National Cancer Institute, created Gius and colleagues mice lacking some of these sirtuins They reported in the. Last January in Cancer Cell, they knocked out Sirt3 – locates a sirtuin in the mitochondria, the cellular ‘power plants ‘ – the mice ER / PR positive breast tumors, the most common form of breast cancer in postmenopausal women develops.
