Purpose:
To study the effect of the modulation of inositol hexaphosphate (IP6) in the biological immunohistochemistry expression of cellular signaling marker apoptosis, in model of carcinogenesis of colon induced by azoxymethane (AOM).
Methods:
Wistar rats (N=112) distributed in 4 groups (n=28): Control; B, AOM (5 mg kg-1, 2x, to break week 3); C, IP6 (in water 1%, six weeks); D, IP6+AOM. Weekly euthanasia (n=7), from week three. Immunohistochemistry of ascendant colon with biological marker inositol 1,4,5 triphosphate receptor type III (Itpr3). Quantification of the immune-expression with use of computer-assisted image processing. Analysis statistics of the means between groups, weeks in groups, groups in weeks, and established significance when p
Results:
One proved significant difference between groups in the expression of Itpr3, p<0.0001; with Itpr3 reduction of BxD group, p<0.001.
Conclusion:
Inositol hexaphosphate promotes modulation of biological markers with reduction of Itpr3 in carcinogenesis of colon.
