Immunomodulatory effect of Myrtenol on benzo (a) pyrene‐induced lung cancer in Swiss albino mice via modulation of tumor markers, cytokines and inhibition of PCNA expression

Abstract

AbstractLung cancer is one of the most common cancers in men. Although many diagnostic and treatment regimens have been followed in the treatment for lung cancer, increasing mortality rate due to lung cancer is depressing and hence requires alternative plant based therapeutics with with less side‐effects. Myrtenol exhibits anti‐inflammatory and antioxidant properties. Hence we intended to study the effect of Myrtenol on B(a)P‐induced lung cancer. Our study showed that B(a)P lowered hematological count, decreased phagocyte and avidity indices, nitroblue tetrazolium (NBT) reduction, levels of immunoglubulins, antioxidant levels, whereas Myrtenol treatment restored them back to normal levels. On the other hand, xenobiotic and liver dysfunction marker enzymes and pro‐inflammatory cytokines were elevated on B(a)P exposure, which retuned back to normal by Myrtenol. This study thus describes the immunomodulatory and antioxidant effects of Myrtenol on B[a]P‐induced immune destruction.
