LncRNA RMST activates TAK1-mediated NF-κB signaling and promotes activation of microglial cells via competitively binding with hnRNPK.

This study aimed to explore the biological role and molecular mechanism of long noncoding RNA (lncRNA) rhabdomyosarcoma 2-associated transcript (RMST) in regulating microglial activation. Mouse microglial BV2 cells were cultured to establish the cell model of cerebral ischemic stroke by oxygen-glucose deprivation (OGD). We observed highly expressed RMST, increased expression of M1, and decreased expression of M2 markers in BV2 microglial cells stimulated with OGD.
