Abstract
Cancer is currently the second major cause of mortality globally. It is a collection of disorders categorized as abnormal cell development which can infiltrate and can spread to countless sections of the body. It has been essentially brought about by genetic and environmental sources mainly, countless patients have impacted by ecological factors like polycyclic aromatic hydrocarbons (PAHs). However, many PAHs in the ecosystem are generated from natural factors like direct combustion, petroleum and volcanic activity. Among these, 7,12 dimethylbenz[a]anthracene (DMBA) has been widely recognized for its capability to induce carcinogenesis in animals and humans. The carcinogenic activity of DMBA indicates the impact of well-differentiated tumors and it is recognized for generating DNA-reactive species that increase the oxidative damage in cells through their metabolism. Additionally, the configuration of DNA adducts and oxidative intermediates acquired from DMBA metabolism impairs prominent cellular activities by harming lipid and protein barriers. DNA adduct is made up of highly reactive intermediates. DMBA-induced cancer displayed higher expression of aryl hydrocarbon receptor (AhR), c-Myc, cyclinD1, activation of upstream regulatory mechanisms and frequent detection of NF-κB pathway components. In this study, we emphasized the growth of several cancers and the kinetic impact of DMBA to probable chemical carcinogenic activities.
