The glomerular circadian clock temporally regulates basement membrane dynamics and the podocyte glucocorticoid response

Kidney physiology shows diurnal variation, and a disrupted circadian rhythm is associated with kidney disease. However, it remains largely unknown whether glomeruli, the filtering units in the kidney, are under circadian control. Here, we investigated core circadian clock components in glomeruli, together with their rhythmic targets and modes of regulation. With clock gene reporter mice, cell-autonomous glomerular clocks which likely govern rhythmic fluctuations in glomerular physiology were identified.
