LncRNA MALAT1 Facilitates Parkinson's Disease Progression by Increasing SOCS3 Promoter Methylation.

Introduction: Long noncoding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) has been shown to be involved in Parkinson's disease (PD) progression, but its mechanism needs to be further explored.

Methods: Mice were injected with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) to induce PD mice models, and BV2 cells were treated with lipopolysaccharides (LPS) to mimic PD cell models. MALAT1 expression and suppressor of cytokine signaling 3 (SOCS3) protein level were examined using quantitative real-time PCR and Western blot, respectively.

LncRNA SOX21-AS1 Promotes Activation of BV2 Cells via Epigenetical Silencing of SOCS3 and Aggravates Parkinson's Disease.

Background: LncRNAs perform a crucial impact on microglia's activation in Parkinson's disease (PD). Here, our purpose was to probe the function and involved mechanism of lncRNA SOX21-AS1 on microglial activation in PD.

Methods: Mice were treated with MPTP, and BV2 cells were treated with LPS/ATP to build PD animal and cell models.
