Abstract EN
Peroxisome proliferator-activated receptor α (PPARα) is a member of the nuclear hormone receptor superfamily and functions as a transcription factor.
Previous work showed that PPARα plays multiple roles in lipid metabolism in tissues such as cardiac and skeletal muscle, liver, and adipose tissue.
Recent studies have discovered additional roles for PPARα in cell proliferation and metabolism, as well as tumor progression.
PPARα is aberrantly expressed in various cancers, and activated PPARα inhibits the proliferation of some tumor cells.
However, there have been no studies of PPARα in human gliomas.
Here, we show that PPARα is expressed at lower levels in anaplastic gliomas and glioblastoma multiforme (GBM) tissue compared with low-grade gliomas tissue, and low expression is associated with poor patient prognosis.
PPARα activates transcription of dynamin-3 opposite strand (DNMO3os), which encodes a cluster of miR-214, miR-199a-3p, and miR-199a-5p microRNAs.
Of these, miR-214 is transcribed at particularly high levels.
PPARα-induced miR-214 expression causes downregulation of its target E2F2.
Finally, miR-214 overexpression inhibits glioma cell growth in vitro and in vivo by inducing cell cycle arrest in G0/G1.
Collectively, these data uncover a novel role for a PPARα-miR-214-E2F2 pathway in controlling glioma cell proliferation.
