Effect of NF - κB inhibitor on renal expression of apolipoprotein M in rats with acute renal failure / 中国病理生理杂志

ABSTRACT

AIM: To investigate the expression pattern of apolipoprotein M (apoM) protein in renal cortex of a-cute renal failure ( ARF) rats with reperfusion. METHODS: Seventy - five male rats were randomly divided into sham operation group (re =25) , ARF group (n =25) and pyrrolidine dithiocarbamat (PDTC) group (n =25) , five subgroups at time points of 3 h, 6 h, 12 h, 24 h and 48 h after reperfusion were set up in each group. The expressions of apoM in cytoplasm and NF - κB p65 in nucleus of renal cortex were detected at the indicated time points. RESULTS: The expression of apoM in ARF group was obviously higher than that in sham operation group ( P <0.01 ) , and two peaks were detected, the first peak was at 6 h after reperfusion, while the second one was from 24 h to 48 h. The tendency of apoM expression in PDTC group was similar to that in ARF group, while the expression in every subgroup was prevalently lower than that in ARF group (P < 0.01). Otherwise, a significant correlation ( r = 0.852, P < 0.01) was found between the expression of apoM and NF -κB p65.CONCLUSION: The results indicate that apoM feasibly take part in the pathogenesis of ARF through the inflammatory reaction mediated by NF - κB.
