(A) Butyrate-supplemented diets enhanced apoptosis only in rats consuming fish oil. All animals were injected with AOM. Apoptosis was measured in the distal colon only. The apoptotic index represents number of apoptotic cells/total number of cells per crypt column × 100. Data are means ± SEMs for 10 rats per diet per treatment group. For each rat, 50 well-oriented crypt columns were assessed. Bars with different letters are significantly different (P < 0.02). (B) Inverse relationship between the apoptotic index and the number of ACF per animal (r = −0.63228; P < 0.05). No relationship between AOM-injected rats fed corn oil + butyrate diets (r = −0.2873; P > 0.05) was observed. Refer to Figure 1 for legend details.
