A voluminous number of evidence suggests that an increased consumption of fruits and vegetables is a relatively easy and practical strategy to reduce significantly the incidence of cancer. The present study is an effort to identify the chemopreventive role of alkaloid capsaicin against benzo(a)pyrene-induced lung cancer in Swiss albino mice. Benzo(a)pyrene-induced lung cancer-bearing animals showed abnormal changes in body weight, lung weight, tumour incidence and alterations in the activities of marker enzymes adenosine deaminase, aryl hydrocarbon hydroxylase, gamma-glutamyl transpeptidase, 5'-nucleotidase and lactate dehydrogenase. On capsaicin pre-co-treatment, all the above alterations were returned to near normal. Immunohistochemical analysis of proliferating cell nuclear antigen together with lung histological examination further supported our biochemical findings that demonstrated the chemoprotective role of capsaicin against benzo(a)pyrene-induced experimental lung cancer.

The nutrition condition of earlier life has a long-term influence on health of its later period. In order to the explore effects of in ovo feeding of vitamin C on splenic development, splenic metabolism and apoptosis were detected in embryo, adult chickens and in vitro. A total of 360 fertile eggs were selected and randomly assigned to 2 treatments: the control group (CON) and vitamin C group (VC) were injected with saline and vitamin C on embryonic day 11, respectively. Functional enrichment of differentially expressed genes by transcriptome on embryonic day 19 suggested that purine nucleotide metabolism might be a potential pathway for the in ovo feeding of vitamin C to regulate spleen development. Additionally, the in ovo feeding of vitamin C significantly increased splenic vitamin C content on post-hatch day 21. Meanwhile, the splenic expression of adenosine deaminase, serine/threonine kinase 1 and proliferating cell nuclear antigen were down-regulated, whereas the expression of cysteinyl aspartate specific proteinase 9 was up-regulated in VC group. On post-hatch day 42, the in ovo feeding of vitamin C significantly down-regulated the splenic expression of B-cell lymphoma 2, and increased the mRNA level of cysteinyl aspartate specific proteinase 9. The in ovo feeding of vitamin C could regulate the expression of genes related to adenylate metabolism and increased the apoptosis rate in vitro, which consistent with the result in vivo. Together, these results illustrated that the in ovo feeding of vitamin C regulated splenic development and maturation by affecting purine nucleotide metabolism pathway and promoting apoptosis.
