BACKGROUND: Solid Ehrlich Carcinoma (SEC) is an undifferentiated tumor used in tumor studies and chemotherapy investigations.
AIM: to assess the anti-tumor potential of luteolin when used either alone or combined to 5-fluorouracil (5-FU) against SEC.
METHOD: SEC was induced in 40 female mice; they were categorized into 4 equal groups; group I (untreated SEC), group II (5-FU treated SEC), group III (luteolin treated SEC) and group IV (5-FU + luteolin treated SEC). Tumor volume and weight were calculated. P53, p21, caspase 3 and damage regulated autophagy modulator (DRAM) were assessed. Biomarkers of oxidant/antioxidant status in addition to immunohistochemistry for cylin D1 were evaluated.
RESULTS: combined administration of luteolin and 5-FU in SEC model increased levels of p53, p21, caspase 3, DRAM and survivability while, tumor volume, weight, thioredoxin reductase one (TR1) activity and cyclin D1 expression showed the reverse with restoration of oxidant/antioxidant indices.
CONCLUSION: current results proved the antitumor therapeutic effects of luteolin alone or combined with 5-FU as a novel strategy for cancer therapy.
