Abstract

To explore whether microRNA-377 could participate in the development of Alzheimer's disease (AD) by regulating CDH13. In this research, AD model was constructed by the SH-SY5Y cells. The expression levels of microRNA-377 and CDH13 in the AD model were detected by quantitative Real-time polymerase chain reaction (qRT-PCR). The cell viability and apoptosis after knockdown of microRNA-377 and CDH13 were measured by cell counting kit-8 (CCK-8) assay and flow cytometry, respectively. The regulatory mechanism of microRNA-377 on CDH13 was confirmed by dual-luciferase reporter gene assay, qRT-PCR and Western blot. Downregulated microRNA-377 and upregulated CDH13 were observed after successful construction of the AD model. Cell viability in the AD model group was significantly reduced compared with that of the control group. Moreover, downregulated microRNA-377 could further inhibit the cell viability, which was reversed by CDH13 knockdown. Cell apoptosis in the AD model group was enhanced after microRNA-377 knockdown, which was rescued by decreasing the expression level of CDH13. MicroRNA-377 was confirmed to regulate the expression level of CDH13 by dual-luciferase reporter gene assay, qRT-PCR and Western blot. MicroRNA-377 could regu...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
