Chlorogenic Acid Exerts Beneficial Effects in 6-Hydroxydopamine-Induced Neurotoxicity by Inhibition of Endoplasmic Reticulum Stress.

BACKGROUND Chlorogenic acid (CGA), a dietary polyphenol derived from many plants, has been previously reported to exert neuroprotective properties. However, its pharmacological role in Parkinson's disease (PD) and the underlying mechanisms are unclear. MATERIAL AND METHODS In the present study, we investigated the beneficial effects of CGA against the toxicity of 6-hydroxydopamine (6-OHDA) in animal and cellular models.

MicroRNA-93 inhibits inflammatory responses and cell apoptosis after cerebral ischemia reperfusion by targeting interleukin-1 receptor-associated kinase 4.

The present study aimed to investigate changes in the expression of interleukin (IL)-1 receptor-associated kinase 4 (IRAK4) and microRNA (miRNA or miR)-93 in mice with cerebral ischemia reperfusion (CIR) injury, as well as the association and regulatory mechanism between IRAK4 and miR-93. The CIR mouse model was constructed and mouse microglia BV2 cells were transfected with miR-93 mimic or miR-93 inhibitor. Quantitative polymerase chain reaction was used to measure the expression of mRNA and miR-93.
