Dystonin/BPAG1 modulates diabetes and Alzheimer's disease cross-talk: a meta-analysis.

Dementia is one of the diabetic complications under intensive study. Alteration of synaptic adhesion protein (SAP) associates with neurological diseases, including Alzheimer's disease. However, the regulation of SAPs in the brain of diabetes mellitus remains elusive. To pinpoint the candidate SAPs underlining the mechanism of diabetic dementia, we investigated expression profiling of SAPs in both streptozotocin (STZ)-induced diabetic mice, AppNL-G-F/NL-G-F mice, and amyloid precursor protein intracellular domain (AICD)-induced human neural cell line from public databases. DST (Dystonin/BPAG1) was identified upregulated in both models. Our finding suggests that DST alteration may involve in the mechanism of diabetic dementia.
