Reversible dysregulation of renal circadian rhythm in lupus nephritis.

Project description:BackgroundWe have found disruption of expression of major transcriptional regulators of circadian rhythm in the kidneys of several mouse models of lupus nephritis. Here we define the consequence of this disturbance with respect to circadian gene expression and renal homeostatic function in a mouse model of lupus nephritis.MethodsMolecular profiling of kidneys from 47 young and 41 nephritic female NZB/W F1 mice was performed at 4 hourly intervals over a 24 h period. Disruption of major circadian transcriptional regulators was confirmed by qPCR. Molecular data was normalized and analyzed for rhythmicity using RAIN analysis. Serum aldosterone and glucose and urine sodium and potassium were measured at 4 hourly intervals in pre-nephritic and nephritic mice and blood pressure was measured every 4 h. Analyses were repeated after induction of complete remission of nephritis using combination cyclophosphamide and costimulatory blockade.ResultsWe show a profound alteration of renal circadian rhythms in mice with lupus nephritis affecting multiple renal pathways. Using Cosinor analysis we identified consequent alterations of renal homeostasis and metabolism as well as blood pressure dipper status. This circadian dysregulation was partially reversed by remission induction therapy.ConclusionsOur studies indicate the role of inflammation in causing the circadian disruption and suggest that screening for loss of normal blood pressure dipping should be incorporated into LN management. The data also suggest a potential role for circadian agonists in the treatment of lupus nephritis.

Kidney gene expression profiles from a lupus nephritis mouse model: SNF1 (SWR X NZB F1) mice treated with pristane

Project description:We characterized the longitudinal gene expression profiles of kidneys from a novel lupus model nephritis: SNF1 (SWR X NZB F1) mice treated with pristane. Genes from biological processes such as IFN response, complement, Fc gamma receptors, immune recruitment, innate immune pattern recognition, antibody response and fibrosis,were upregulated in diseased kidneys.

Effect of Sirolimus treatment on lupus nephritis in NZB/W F1 female mice

Project description:NZB/WF1 female mice spontaneously develop autoimmune lupus nephritis. Expression profiling of kidney tissue from (a) 12 week NZB/W F1 female mice defined as asymptomatic for lupus nephritis, (b) 36 and 42 week NZB/W F1 female mice defined as diseased/symptomatic for lupus nephritis and (c) 36 and 42 week NZB/W F1 female mice that are diseased/symptomatic for lupus nephritis and treated with Sirolimus was carried out. The goal of the study was to identify genes associated with lupus nephritis and modulated by Sirolimus, an inhibitor of mTOR. In addition, lupus nephritis genes resistant to Sirolimus therapy were also identfied This series of samples comprises of kidney tissue from (a) 12 week old NZB/W F1 female mice defined as asymptomatic for lupus nephritis (N=4), (b) 36 (N=3) and 42 week (N=3) old NZB/W F1 female mice defined as diseased/symptomatic for lupus nephritis and (c) 36 (N=3)and 42 (N=3) week old NZB/W F1 female mice that are asymptomatic for lupus nephritis on treatment with Sirolimus
