It is widely accepted that genetic mutation plays an important role in the development of cancers. However, accumulating evidence suggests that more than 60% of human cancers are attributable to environment and lifestyles, including air pollution, drinking water contamination, some special work settings, and smoking. Even for some types of cancers that have strong association with genetic abnormalities, such as BRCA1 or BRCA2 gene mutations for breast cancer and ovarian cancer, certain environmental factors had been viewed as environmental modifiers that alter the metabolisms of hormone and DNA repair capacity of the cells to trigger or facilitate tumorigenesis, which explains why only certain portion of the people with inherited genetic mutation developed cancers. Accordingly, it is very likely that cancers are caused by a web of interacting factors, including environmental exposure, genetic predisposition and lifestyle.
The state of Michigan, especially in the Detroit tri-county area of Macomb, Oakland and Wayne, exhibits a unique cancer epidemiological pattern, which provides the strongest support for the importance of environmental exposure on the increased or sustained cancer incidence and mortality rates. During the past three decades, the lung cancer incidence rate in Michigan is above the national average, while the prevalence of tobacco smoking is comparable to the national average at the same or the previous period. In the Detroit tri-county area, the Wayne County, in which the air quality is the poorest due to the presence of many chemical, refinery and manufacture industries, shows the highest rate of lung cancer, colorectal cancer and prostate cancer relative to Macomb county and Oakland County in the past several years.
The members in this focused group are leaders in their field and actively involved in cutting edge projects that range from discovery of basic biological mechanisms to clinical concepts and application of healthcare on cancers associated with environmental exposure. The objectives of this research interest group is to determine whether a given environmental factor is able to activate a specific carcinogenic or tumorigenic process in addition to DNA damage, such as altering the epigenetic landscape of the genome to reduce the genomic stability, inducing self-renewal and clone expansion of the cancer stem cells, preventing apoptosis of the transformed or tumor cells, and enhancing angiogenesis and tumor cell metastasis. Additional objectives include but not limited to translating knowledge of a carcinogenic effect of environmental risk factors into preventive strategies for the exposed population; assessing carcinogenic potentials for those newly identified environmental risk factors through both epidemiological and laboratory settings; determining the key windows of vulnerability of individuals in response to environmental exposure; and developing new research tools or methodologies in assessing cancer risk associated with multiple environmental exposures.
