Research team from Daegu Gyeongbuk Institute Of Science And Technology (DGIST) has performed a high-throughput screening method to identify drug candidates that promote dopaminergic neuronal cell activation by inducing the expression of the parkin protein, the cell protection gene which can inhibit the death of dopaminergic neurons. The results of study are published in Scientific Reports.
Results of the study identified that cortisol induces the expression of the parkin protein and prevents dopaminergic neuronal death by eliminating the accumulation of cell death factors through ubiquitin proteasome system.
In addition, the team has demonstrated the mechanism by which cortisol induces the expression of the parkin protein and CREB (cAMP response element-binding protein) transcriptional regulator through the hormone receptor regulates the expression of the parkin protein through the cell and animal model experiments.
