Azacitidine 55-66 paired box 5 Homo sapiens 99-116 21779426-5 2010 They then show that expression of all 3 genes is restored in T98 GBM cells by treatment with the histone deacetylase inhibitor Trichostatin A (TSA), but only DKK1 expression is restored by treatment with the demethylating agent 5-azacytidine. Azacitidine 228-241 paired box 5 Homo sapiens 34-39 27029827-2 2017 Our previous study showed that DNA demethylating agent Azacitidine (Aza) demethylated CpG sites in paired box gene 5 (pax5) promoter region, but did not induce pax5 mRNA or protein expression. Azacitidine 55-66 paired box 5 Homo sapiens 118-122 27029827-2 2017 Our previous study showed that DNA demethylating agent Azacitidine (Aza) demethylated CpG sites in paired box gene 5 (pax5) promoter region, but did not induce pax5 mRNA or protein expression. Azacitidine 55-58 paired box 5 Homo sapiens 99-116 27029827-2 2017 Our previous study showed that DNA demethylating agent Azacitidine (Aza) demethylated CpG sites in paired box gene 5 (pax5) promoter region, but did not induce pax5 mRNA or protein expression. Azacitidine 55-58 paired box 5 Homo sapiens 118-122 27029827-4 2017 We treated pax5- silenced NSCLC H460 cells with Aza+SAHA combination at sub-toxic concentration and detected the re-expression of pax5 mNRA and protein. Azacitidine 48-51 paired box 5 Homo sapiens 11-15 27029827-4 2017 We treated pax5- silenced NSCLC H460 cells with Aza+SAHA combination at sub-toxic concentration and detected the re-expression of pax5 mNRA and protein. Azacitidine 48-51 paired box 5 Homo sapiens 130-134 27029827-5 2017 RESULTS: The results showed demethylation of CpG sites in pax5 promoter region by Aza treatment and increased DNA accessibility for protein binding by SAHA treatment. Azacitidine 82-85 paired box 5 Homo sapiens 58-62 27029827-6 2017 The combination of Aza+SAHA significantly increased p53 protein binding to DNA in pax5 promoter region (p<0.01). Azacitidine 19-22 paired box 5 Homo sapiens 82-86 27029827-7 2017 More efficient binding of the transcription factor p53 to pax5 promoter region is likely because SAHA increased accessibility of the chromatin conformation and Aza-demethylated DNA was more permissive, allowing transcription factors to bind. Azacitidine 160-163 paired box 5 Homo sapiens 58-62 27029827-8 2017 CONCLUSION: Our study not only explained an underlying mechanism, that pax5 re-expression was induced by Aza+SAHA combination in H460 cells via p53, but also demonstrated a pattern showing that the combination of demethylating agent and HDAC inhibitor can re-activate tumor suppressor gene (TSG) which is associated with the enhancement of transcription factors binding to the promoter region of the TSG.
