The Mechanism of lncRNA NEAT1 in Alleviating Acute Respiratory Distress Syndrome Through miR-27b Regulated Nrf2 Pathway
16. juni 2021 oppdatert av: Guangfa Zhu, Beijing Anzhen Hospital
The acute respiratory distress syndrome, formerly known as the acute lung injury (ARDS/ALI), is a critical illness with high mortality due to the lack of effective treatment.
The pathogenesis of ARDS/ALI has not been fully elucidated.
Nuclear factor E2-related factor 2 (Nrf2) plays a key role in regulating lung inflammation and oxidative stress which are closely related to lung injury in ARDS/ALI, but its regulatory mechanism remains unclear.
The investigator's provious study shown that microRNA-27b (miR-27b) downregulated Nrf2 to aggravate lung inflammation and histological injury.
Furthermore, in lipopolysaccharide (LPS)-induced cell (J774A.1)
inflammation model, miR-27b was upregulated while the long non-coding RNA (lncRNA) NEAT1 was downregulated, the putative binding sites of lncRNA NEAT1 and miR-27b were successfully predicted by bioinformatics approach.
Thus, the investigators propose that NEAT1 plays as a competing endogenous RNA (ceRNA) to adsorb miR-27b and liberate Nrf2, therefore, to attenuate lung inflammation and related lung injury in ARDS/ALI.
This project aims to explore the role of the lncRNA NEAT1/ mir-27b /Nrf2 signal axis in the development and treatment of ARDS/ALI in patients, as well as in LPS-induced ALI animal and cell models by using bioinformatics, molecular biology, histomorphology and clinical phenotype approaches, and to clarify the new mechanism in ARDS/ALI development and to provide new therapeutic targets.

Detaljert beskrivelse
Collect blood and BALF from 400 ARDS patients at different time (at check-in, 24, 48 and 72 h after check-in the hospital) and 25 gender and age matching healthy controls.
Use RT-PCR to detect the expression of lncRNA NEAT1、miR-27b and Nrf2 in blood and BALF of ARDS patients and health controls.
The expressions of inflammatory and oxidative stress associated factors (NLRP3、NF-κB-P65、 p-P65、IκB、p-IκB、HO-1、NQO1、caspase-1、IL-1β、IL-6、IL-18、TNF-α) will be detected by western blot、ELISA and RT-PCR.
Moreover, flow cytometry will be adopted to measure the numbers and kinds of cells in BALF.
Then, analyze the differences of the expressions of lncRNA NEAT1、miR-27b and Nrf2 in the groups.
To explore the correlation of expressions of lncRNA NEAT1、miR-27b and Nrf2 with inflammation and oxidative stress in the groups.
Finally, to declare the relative of lncRNA NEAT1、miR-27b and Nrf2 with the time of mechanical ventilation, severity and mortality in 28 days of ARDS patients.
