ReviewCell-cycle arrest and acute kidney injury: the light and the dark sides.
Acute kidney injury (AKI) is a common consequence of systemic illness or injury and it complicates several forms of major surgery. Two major difficulties have hampered progress in AKI research and clinical management. AKI is difficult to detect early and its pathogenesis is still poorly understood. ⋯ Cell-cycle arrest is known to be involved in the pathogenesis of AKI and this 'dark side' may also involve progression to chronic kidney disease. However, cell-cycle arrest has a 'light side' as well, since this mechanism can protect cells from the disastrous consequences of entering cell division with damaged DNA or insufficient bioenergetic resources during injury or stress. Whether we can use the light side to help prevent AKI remains to be seen, but there is already evidence that cell-cycle arrest biomarkers are indicators of both sides of this complex physiology.
