Figure 6. Comparative gene expression ratios in ARF kidneys of MSC- and vehicle-treated animals. Data were generated by referencing each gene to p-actin as internal control. A MSC treatment cansed significant (P < 0.05) suppression (> 10 fold) of proinflammatory IL-ip, TNF a, and IFN-y (above bars actnal valnes). Anti-inflammatory lL-10 was robustly expressed in MSC-and not in vehicle treated animals. Filled bars on all panels depict gene expression ratio of 1, i.e., a value obtained when gene expression ratios between MSC- and vehicle-treated animals are "equal. B MSC treatment cansed increased gene expression of bFGF and TGF-a, whereas that of HGF was suppressed. C antiapoptotic Bcl-2 expression was robnstly indnced, whereas that of inducible nitric oxide synthase (iNOS) was snppressed in MSC- vs. vehicle-treated animals. eNOS, endothelial NOS.

In addition we have shown that IL-1 also induces the expression of c-jun in both islets and RINm5F cells, and have obtained preliminary evidence for nuclear factor RB (NF-kB) activation (J. A. Corbett and M. L. McDaniel, unpublished observation). TTiese three transcriptional regulators alone or in combination are believed to participate in IL-1-induced expression of nitric oxide synthase by the islet j8 cell. Importantly, Nathan and co-workers have shown the presence of NF-kB response elements upstream of the mouse macrophage iNOS gene (Xie et cd., 1993).
