Malformations in the Murine Kidney Caused by Loss of CENP-F Function

Centromere-binding protein F (CENP-F) is a large and complex protein shown to play critical roles in mitosis and various other interphase functions. Previous studies have shown that the disruption of CENP-F function leads to detrimental effects on human development. Still, it is important to note the lack of studies focusing on the effects that the loss of this essential protein may have on specific adult organs. In the current study, we used a novel global knockout murine model to analyze the potential consequences deletion of CENP-F has on adult kidney structure and function. We discovered several structural abnormalities including loss of ciliary structure, tubule dilation, and disruption of the glomerulus. Along with these structural irregularities, renal dysfunction was also detected suggesting hydronephrosis and acute kidney injury in these knockout organs. Importantly, this is the first study linking CENP-F to kidney disease and hopefully these data will serve as a platform to further investigate the molecular mechanisms disrupted in the kidney by the loss of CENP-F.
