Crosstalk Relationship Histone modification  →  m6A Enhancement
Crosstalk Mechanism histone modification directly impacts m6A modification through modulating the level of m6A regulator
Crosstalk Summary The transcription factor ETS1 recruited p300 and WDR5 which separately mediated Histone H3 lysine 27 acetylation (H3K27ac) and H3K4me3 histone modification in the promoter of METTL3 and induced METTL3 transcription activation. Furthermore, we identified TXNDC5 as a target of METTL3-mediated m6A modification through MeRIP-seq, and revealed that METTL3-mediated TXNDC5 expression relied on the m6A reader-dependent manner. METIL3 is believed to enhance the expression of Long intergenic non-protein coding RNA 426 (LINC00426) through m6A methylation modification.The LINC00426/miR-200a-3p/ZEB1 axis plays a crucial role in regulating E-cadherin, N-cadherin and vimentin during EMT in CC.Overexpression of LINC00426 in CC cells caused resistance to Cisplatin and Bleomycin, but sensitivity to imatinib.
Responsed Disease Cervical cancer ICD-11: 2C77
Responsed Drug Cisplatin
In-vitro Model
HeLa Endocervical adenocarcinoma Homo sapiens CVCL_0030
C-33 A Cervical squamous cell carcinoma Homo sapiens CVCL_1094
SiHa Cervical squamous cell carcinoma Homo sapiens CVCL_0032
In-vivo Model HeLa cells were stably transfected with LINC00426 overexpression lentivirus. Subsequently, for subcutaneously implanted tumor model, mice were randomly divided into two groups, and cells (1 × 107/100 μ l) mixed with the same volume of matrix gel were injected subcutaneously into the right abdomen of mice. One month later the mice were executed and the tumors were stripped and weighed, measured for volume, and used for further analysis. For tumor metastasis assay, mice were randomly grouped, and 5 × 105/100 μ l HeLa cells transfected with NC and LINC00426 overexpression lentivirus were intravenously injected into the tail vein of BALB/c nude mice which were sacrificed after 1 month.
