Figure 3. DSS-induced colitis alters L-Arg metabolic pathway protein levels.

7-week-old C57BL/6 mice received 4% DSS in the drinking water or water alone (Ctrl) for 7 days. At sacrifice on day 7, the colon was removed and tissues were obtained for protein isolation and assessment by Western blotting. Each lane represents a different mouse. There were two separate blots that were used, so the appropriate β-actin housekeeping gene control is placed under the blots for the proteins of interest that were performed on those same membranes.
