Circ-Bnc2 alleviates neuroinflammation in LPS-stimulated microglial cells to inhibit neuron cell apoptosis through regulating miR-497a-5p/HECTD1 axis.

ABSTRACT:

Background

Neuroinflammation caused by microglia cells activation and the apoptosis of neuron cells are associated with the occurrence of depression. Circ-Bnc2 has been shown to be significantly downregulated in depression mice, but its role in the progression of depression remains unclear.

Methods

Lipopolysaccharide (LPS) was used to treat BV2 microglial cells to induce neuroinflammation. The expression of circ-Bnc2, microRNA (miR)-497a-5p, and HECT domain E3 ubiquitin protein ligase 1 (HECTD1) was measured by quantitative real-time PCR. The protein levels of neuroinflammation markers, apoptosis markers, and HECTD1 were determined by western blot analysis. ELISA assay was used to examine the concentrations of inflammatory factors. After HT22 cells were cultured with the con
