In conclusion, the present study suggested that curcumin post-treatment

augments B(a)P-induced apoptosis, and this eventually resulted in increased loss of adducts containing cells in mice evaluated at 24-120 h, suggesting the role of apoptosis in removal of adduct containing cells. Curcumin-mediated enhanced loss in BPDE-DNA adduct containing cells probably results Enzalutamide ic50 in reduction in the numbers of initiated cells in respective tissues, and this, along with curcumin-mediated inhibition of cell proliferation in these tissues leads to decrease in tumor multiplicity/tumor area/volume.

“Lectins

include a group of proteins from non-immune origin that share the property of binding specifically and reversibly to carbohydrates [1]. Many plant lectins have attracted the attention due to their effects on proliferation and differentiation of animal cells, including lymphocytes and cancer cells. The in vitro and the in vivo antitumor effects of plant lectins are apparently associated with their ability to modulate growth, differentiation, proliferation and apoptosis ( [2], [3] and [4]). Toxicity of lectins must be considered before used as medical tools, mainly because they are considered antinutritional factors. It has been shown that binding lectins to intestinal epithelium can interfere others with nutrient absorption, reduction of

nitrogen retention, increased urine nitrogen excretion and reduction of insulin production in rats ([5], [6], [7] and [8]). Antinutritional and negative effects on digestion and absorption have been described for lectins from different sources ([9], [10], [11] and [12]). Studies with common bean (Phaseolus vulgaris L) lectins show that they can interfere with bowel function, causing changes in systemic metabolism and affecting the growth in rats, decrease in glucose, lipids, vitamin B12 and nitrogen uptake ( [13] and [14]). Adverse effects in organs are produced by some diet lectins, which included Phaseolus vulgaris. Rats fed with navy beans showed morphological changes that include increased weight of kidney and heart, pancreatic acinar atrophy, fatty liver and multiple histological lesions as thymus atrophy respect to control healthy rats.
