PG - e13470 LID - 10.1111/1753-0407.13470 [doi] LID - e13470 AB - AIM: Both the activation of glycogen synthase kinase-3beta (GSK-3beta) and the presence of ApoE epsilon4 genotype have been found to respectively correlate with cognitive decline in patients with type 2 diabetes mellitus (T2DM), who further show a high incidence of developing Alzheimer's disease. However, the relationship between ApoE epsilon4 and GSK-3beta in the cognitive impairment of T2DM patients remains unclear. METHODS: ApoE genotypes and platelet GSK-3beta level were measured in 1139 T2DM patients recruited from five medical centers in Wuhan, China. Cognitive functions were assessed by Mini-Mental State Examination (MMSE). The association and the relationships among apolipoprotein E (ApoE) genotypes, GSK-3beta activity and cognitive function were analyzed by regression and mediating effect analyses, respectively. RESULTS: T2DM patients with ApoE epsilon4 but not ApoE epsilon2 haplotype showed poorer cognitive function and elevated platelet GSK-3beta activity, when using ApoE epsilon3 as reference. The elevation of GSK-3beta activity was positively correlated the diabetes duration, as well as plasma glycated hemoglobin (HbA1c) and glucose levels. Moreover, correlation and regression analysis also revealed significant pairwise correlations among GSK-3beta activity, ApoE gene polymorphism and cognitive function. Lastly, using Baron and Kenny modeling, we unveiled a mediative role of GSK-3beta activity between ApoE epsilon4 and cognitive impairment. CONCLUSION: We reported here that the upregulation of GSK-3beta activity mediates the exacerbation of cognitive impairment by ApoE epsilon4-enhanced cognitive impairment in T2DM patients, suggesting GSK-3beta inhibitors as promising drugs for preserving cognitive function in T2DM patients, especially to those with ApoE epsilon4 genotype.
