Article Title: MEG3 in glioma stem cells promotes glioblastoma angiogenesis through FUBP3-mediated VGF expression
doi: 10.1007/s10238-026-02097-4
Figure Lengend Snippet: MEG3 interacts with FUBP3 to regulate VGF expression in GSCs. ( A ) Silver staining of proteins pulled down by MEG3 specific and antisense probes from T4121 GSCs lysates. ( B ) Immunoblotting validation of FUBP3 expression in proteins retrieved via MEG3 probes and antisense probes from T4121 GSCs lysates, with GAPDH serving as the control. ( C ) RT-qPCR analysis of MEG3 levels following RIP experiments on T4121 and T387 cell lysates using FUBP3 antibody, with IgG serving as the control. Data are presented as mean ± SD ( n = 3 per group). * p < 0.05. ( D ) RT-qPCR analysis of FUBP3 and VGF mRNA levels in T4121 and T387 GSCs with FUBP3 overexpression or knockdown. Data are presented as mean ± SD ( n = 3 per group). * p < 0.05, ** p < 0.01, *** p < 0.001. ( E ) Immunoblotting analysis of FUBP3 and VGF protein levels in T4121 and T387 GSCs with FUBP3 overexpression or knockdown
Article Snippet: Biotinylated antisense DNA probes (listed in Supplementary Table 2, synthesised by Sangon Biotech company) targeting MEG3 transcriptswere hybridized to crosslinked chromatin prepared from GSCs, followed by magnetic bead capture of associated nucleic acids.
