Figure 2. Dietary zinc supplementation reversed age-related decline in serum zinc and reduced whole blood MCP1 levels in old mice.

Figure 2.

Young (2 mo) and old (24 mo) C57BL/6 mice were fed a zinc adequate (ZA) diet or zinc supplemented (ZS) diet for 6 wks. Serum zinc levels were measured by ICP-OES at the end of the study (A). Whole blood were collected at the beginning (wk 0) (B) and end of study (wk 6) (C) to determine MCP1 response in unstimulated whole blood. Data represent mean ± SEM (n = 7–10 per treatment group). Two-way ANOVA was used to test for main effects of zinc status and age and their interaction. NS = not significant.
