LHX9 and glioma: In our CCK-8 assay, we also observed that LHX9 expression had little effect on the growth of glioma cells in the first 72 hours, but within a time window of 96 hours (4 days), we observed that LHX9 had inhibitory effects on cell growth and that downregulation of LHX9 expression promoted the growth of glioma cells.
