Outline of Final Research Achievements |
Cellular Mg2+ plays an important role in various cellular functions, such as energy metabolism, channel activity, and enzyme activity. Therefore, various diseases are caused by abnormal Mg2+ regulation. Recently, several Mg2+ transporters are cloned, but their functional roles are still well unknown. We first observed that the expression levels of SLC41 transporters in aorta were dependent on the Mg2+ intake (low, normal, or high). In addition, we found that phenylephrine-induced contraction was reduced in isolated aorta from low-magnesium-fed mice. Furthermore, we next generated SLC41A1/A2-knockout mice. Interestingly, phenylephrine-induced contraction was reduced in isolated aorta from SLC41A2-knockout mice fed with normal-magnesium diet. These results suggest that SLC41A1/A2 play an important role in vascular function. Further work will be required to define the pathological role of SLC41A1/A2 in cardiovascular diseases.
