Oligoadenylate synthetase-like (OASL) aggravated newcastle disease virus (NDV)-induced necroptosis in glioma cells

Project description:Newcastle disease virus (NDV) has emerged as an oncolytic agent in several cancers. Previous study has shown that NDV exerts cytolytic activity in glioma, however, the underlying mechanism has not been fully uncovered. Here the cytolytic activity of NDV in glioma and the associated mechanisms have been demonstrated. Infection with NDV inhibits cell proliferation and promotes cell apoptosis in LN229 cells. Further investigation showed that cytoplasmic organelle damage and cytoplasmic vacuolation were observed in LN229 cells after NDV infection. JC-1 staining assay proved that NDV caused cell apoptosis of LN229 cells by inducing mitochondrial dysfunction. We next speculated that NDV caused LN229 cells death through inducing necroptosis, but not ferroptosis, since the Fe2+ level did not alter after NDV infection. Furthermore, the NDV-caused cell death in LN229 cells was blocked by necroptosis inhibitor Nec1. Besides, RNA-seq analysis identified the different expression genes in NDV-infected LN229 cells. OASL, an antiviral gene, has been found to be directly induced by NDV infection. We also found that knockdown of OASL enhanced NDV infection-induced LN229 cells necroptosis. In summary, two aspects about cytolytic activity of NDV in glioma have been demonstrated. NDV presented cytolytic activity in glioma cells through inducing necroptosis. Additionally, targeting OASL may provide new strategy for enhancing necroptosis of glioma cells after NDV infection.

miR-139-5p induced gene expression alteration in glioma cells

Project description:To evaluate gene expression alteration following miR-139-5p transfection in glioma cells. We find a significant downregulation of two transcriptional factors, E2F3 and HoxA9. Total RNA were extracted from U87, LN229 and U251 glioma cells transfected with miR-139-5p or miRNA negative control.
