Abstract:
Type 2 diabetes (T2D) caused by the complex interplay of both genetic and environmental factors, is a serious public health issue. Compelling evidence from epidemiological studies has highlighted that an unhealthy lifestyle, such as obesity, physical inactivity and poor diet are significant drivers of the epidemic of T2D. Meanwhile, recent genome-wide association studies (GWAS) have identified a large number of T2D and glycemic traits loci. Emerging data emphasize the critical role that gene-environment interactions have played in the development of T2D. Identifying the genetic, environmental factors and their complex interplays may help elucidate the biological pathways of T2D, identify the high-risk groups and characterize heterogeneity in intervention programs. This review summarized the studies investigating gene-environment interactions of T2D.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...
Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
