Article Title: In vitro and in vivo interactions between glioma and marrow-isolated adult multilineage inducible (MIAMI) cells.

doi: 10.1016/j.brainres.2012.07.030

Figure Lengend Snippet: Fig. 1 – Direct co-culture assay of MIAMI cells and aneuploid glioma cell lines. The DNA contents of glioma cells and MIAMI cells were analyzed by flow cytometry and the PI of aneuploid cells alone or co-cultured with MIAMI cells was calculated. (A) Example of flow cytometry histograms showing the DNA content of a co-culture of MIAMI cells (DI¼1) with aneuploid glioma cells (HS683, DI¼1.79). (B) Bar graph showing the PI of aneuploid cells alone or co-cultured with MIAMI cells. The proliferation of A172 and U118MG cell lines co-cultured for 72 h with MIAMI cells was significantly higher, and the proliferation of Lab2 and U138MG cell lines was significantly lower than control cultures. No significant differences were observed for the HS683 and Lab1 cell lines (mean7SEM from triplicate wells). n, Po0.05 versus glioma cells alone.

Article Snippet: Five human glioma cell lines were obtained from the ATCC (A172, HS683, U118MG, U138MG, U87MG; LGC Promochem, Molsheim, France) and two (Lab1 and Lab2) were generated from patients undergoing surgery for GB in the Department of Neurosurgery from CHU Angers (Table 1).

doi: 10.3390/cancers13205113

Figure Lengend Snippet: Hypermethylation and histone modifications account for transcriptional downregulation of DIRAS-1 and DIRAS-2. ( A ) Increase in DIRAS-1 and DIRAS-2 mRNA expression in U251MG and Hs683 cells after treatment with 5-azacytidine, ( B ) after treatment with trichostatin A (TSA), and ( C ) after combinational treatment with 5-azacytidine and trichostatin A. ( D ) Increase in DIRAS-1 and DIRAS-2 promoter DNA bound to acetylated H3, indicating DIRAS-1 and DIRAS-2 promoter euchromatinization after TSA treatment in U251MG and Hs683 cells (n.s.: not significant, * p ≤ 0.05, ** p ≤ 0.002, *** p ≤ 0.001).

Article Title: The Potential Significance of the EMILIN3 Gene in Augmenting the Aggressiveness of Low-Grade Gliomas is Noteworthy

doi: 10.2147/CMAR.S463694

Figure Lengend Snippet: EMILIN3 gene function experiment in LN229. qRT-PCR transfected LN229 human glioma cells efficiently (A) . The CCK-8 experiment and live/dead staining findings demonstrated that overexpression of the EMILIN3 gene may increase LN229 cell line proliferation and vitality ( B and C ). Overexpression of the EMILIN3 gene enhances the migration, invasiveness, and colony formation of the LN229 cell line (D-F ).

Article Snippet: The LN229 and HS-683 human glioma cell line were purchased from iCell Bioscience Inc, and grown in DMEM media (Gibco, USA) with 10% foetal bovine serum (BI, USA) and 1g/mL penicillin/streptomycin (Hyclone, USA) at 37 degrees Celsius and 5% carbon dioxide.
