[Q]: Context: Expression of CINCs was regulated differentially in lipopolysaccharide-stimulated rat macrophages. We examined whether the expression of CINCs in lipopolysaccharide-stimulated rat macrophages is similarly inhibited by anti-inflammatory drugs.', 'Rat peritoneal macrophages were stimulated by lipopolysaccharide in the presence of anti-inflammatory steroids (dexamethasone, prednisolone and hydrocortisone) or non-steroidal anti-inflammatory drugs (indomethacin and piroxicam). The production and mRNA expression of three types of CINCs were measured using enzyme-linked immunosorbent assay and northern hybridization.', 'Anti-inflammatory steroids; dexamethasone, prednisolone and hydrocortisone, dose-dependently inhibited the production of CINC-1, -2 and -3, whose inhibitory patterns were similar to each other. Furthermore mRNA expression of each CINC was inhibited by dexamethasone in a dose-dependent manner. In contrast, non-steroidal anti-inflammatory drugs, indomethacin and piroxicam were without effect. Expression of each CINC was regulated differently; the production of CINC-1 reached a maximum at 12 h and then slightly decreased after lipopolysaccharide stimulation, whereas that of CINC-2 and CINC-3 increased up to 24 h. Dexamethasone inhibited the CINCs production and mRNA expression at 9 h after lipopolysaccharide stimulation.
Answer: These results indicate no difference among CINC-1, -2 and -3 in the inhibition of production and mRNA expression of CINCs by anti-inflammatory steroids, although lipopolysaccharide differentially induces expression of each CINC expression in culture of rat macrophages.
[A]: Is the expression of three types of CINCs by lipopolysaccharide-stimulated rat macrophages inhibited similarly by anti-inflammatory steroids?

[Q]: Context: Renal ischemia-reperfusion (I/R) injury is a major cause of acute renal failure (ARF). The transcription factor nuclear factor-kappaB (NF-kappaB) has been implicated as a key mediator of reperfusion injury. Activation of NF-kappaB is dependent upon the phosphorylation of its inhibitor, IkappaB, by the specific inhibitory kappaB kinase (IKK) subunit, IKKbeta. We hypothesized that ischemic preconditioning (IPC) reduces acute renal damage following I/R injury by inhibiting activation of IKKbeta. As neutrophil gelatinase-associated lipocalin (NGAL), an early predictive biomarker of acute kidney injury, is regulated by NF-kappaB, we approached the relationship between NGAL and IKKbeta.', 'Thirty male Sprague-Dawley rats were randomly divided into 3 groups after right kidney nephrectomy. Group A rats were sham-operated controls. Group B rats were 45-min ischemic in the left renal artery while Group C rats were pre-treated with 3 cycles of 2-min ischemia and 5-min reperfusion. All the rats were sacrificed at 24 h after reperfusion. We harvested kidneys and serum to do further analysis, including histological and functional parameters, expressions of NGAL and IKKbeta in renal tissues.', 'Compared with rats subjected to I/R injury, pre-treated rats had a significant decrease in serum creatinine level (Scr) and tubulointerstitial injury scores (Scr, 86.79 +/- 12.98 vs. 205.89 +/- 19.16 mircomol/l, p < 0.01; tubulointerstitial injury scores, 1.3 +/- 0.48 vs. 3.8 +/- 0.79, p < 0.01). In addition, expressions of IKKbeta (0.95 +/- 0.21 vs. 1.74 +/- 0.17, p < 0.05) and NGAL (1.71 +/- 0.032 vs. 2.66 +/- 0.078, p < 0.05) at renal tubule in pre-treated rats were attenuated significantly compared with rats subjected to ischemia-reperfusion injury. Moreover, our study showed that IKKbeta and NGAL were in positive correlation (R = 0.965 > R(0.01)(30) = 0.448, p < 0.01).
Answer: The evidence suggests that IKKbeta may play a role in renal I/R injury and give rise to the generation of NGAL. It appears that IPC may attenuate renal injury and the expression of NGAL following acute I/R injury. IKKbeta may offer a clinically accessible target for preventing renal injury following I/R.
[A]: Does ischemic preconditioning attenuate renal ischemia-reperfusion injury by inhibiting activation of IKKbeta and inflammatory response?

[Q]: Context: Reduced levels of free and total insulin-like growth factor 1 (IGF-I) have been observed in type-1 diabetes (T1D) patients. The bioavailability of IGF-I from the circulation to the target cells is controlled by multifunctional IGF-binding proteins (IGFBPs). The aim of this study was to profile serum IGFBPs in T1D and its complications.', 'We measured the IGFBP levels in 3662 patient serum samples from our ongoing Phenome and Genome of Diabetes Autoimmunity (PAGODA) study. IGFBP levels of four different groups of T1D patients (with 0, 1, 2, and 3 complications) were compared with healthy controls.', 'Three serum IGFBPs (IGFBP-1, -2, and -6) are significantly higher in T1D patients, and these alterations are greater in the presence of diabetic complications. IGFBP-3 is lower in patients with diabetic complications. Analyses using quintiles revealed that risk of T1D complications increases with increasing concentrations of IGFBP-2 (fifth quintile ORs: 18-60, p<10(-26)), IGFBP-1 (fifth quintile ORs: 8-20, p<10(-15)), and IGFBP-6 (fifth quintile ORs: 3-148, p<10(-3)). IGFBP-3 has a negative association with T1D complications (fifth quintile ORs: 0.12-0.25, p<10(-5)).
Answer: We found that elevated serum levels of IGFBP-1, -2, and -6 were associated with T1D, and its complications and IGFBP-3 level was found to be decreased in T1D with complications. Given the known role of these IGFBPs, the overall impact of these alterations suggests a negative effect on IGF signaling.
