ABSTRACT: Objectives
Long non-coding RNA (lncRNA) MATN1-AS1 is a newfound lncRNA that has been rarely explored in cancers. Herein, we would like to investigate its role in glioma.Materials and methods
qRT-PCR was conducted to examine gene expression in glioma. Then, MTT assay, colony formation assay and flow cytometry analysis were applied to evaluate the function of MATN1-AS1 on glioma cells. Western blot was performed to measure the protein levels of genes. Besides, the luciferase reporter assay, RNA pull-down assay, RIP assay and Spearman's correlation analysis were also performed as needed.Results
Firstly, a data from TCGA showed that MATN1-AS1 might be largely implicated in glioma. Meanwhile, MATN1-AS1 upregulation confirmed in glioma predicted poor clinical outcomes. Functionally, MATN1-AS1 knockdown restrained cell proliferation but stimulated apoptosis in vitro and repressed tumour growth in vivo. Mechanistic investigations validated that MATN1-AS1 functioned as a ceRNA for miR-200b/c/429 to upregulate CHD1 which was also verified to exert a growth-promoting role in glioma cells here. Importantly, both CHD1 overexpression and miR-200b/c/429 inhibition could rescue the obstructive role of MATN1-AS1 silence in glioma cells.Conclusions
MATN1-AS1 promotes glioma progression through regulating miR-200b/c/429-CHD1 axis, suggesting MATN1-AS1 as a probable target for glioma treatment.
