[1]
m6A modification miR-20a-5p miR-20a-5p METTL3 Methylation : m6A sites Direct Enhancement Non-coding RNA miR-20a-5p NFIC  lncRNA       miRNA   circRNA
m6A Modification:
m6A Regulator Methyltransferase-like 3 (METTL3) WRITER
m6A Target hsa-miR-20a-5p
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type Non-coding RNA (ncRNA)
Epigenetic Regulator hsa-miR-20a-5p microRNA View Details
Regulated Target Nuclear factor 1 C-type (NFIC) View Details
Crosstalk Relationship m6A  →  ncRNA Enhancement
Crosstalk Mechanism m6A regulators directly modulate the functionality of ncRNAs through specific targeting ncRNA
Crosstalk Summary METTL3 promoted m6A modification and the binding of DGCR8 to hsa-miR-20a-5p to further elevate the miR-20a-5p expression and inhibit Nuclear factor 1 C-type (NFIC) transcription, thus promoting EMT, invasion and migration.

In-vivo Model Male nude mice (age: 4-6 weeks, weight: 22-22 g) provided by the Southern Medical University, were housed in specific pathogen environment at 22-24°C and 50-60% humility under a 12-h light/dark cycle, with ad libitum access to food and water. The nude mice were classified into 3 groups with 18 mice per group: the control group, the sh-NC group, and the sh-METTL3 group. Well-grown ECA109 cells, sh-METTL3-transfected ECA109 cells, sh-NC-transfected ECA109 cells were re-suspended in phosphate buffer saline (PBS) solution and then subcutaneously injected (1 × 107cells/mouse) into the right abdomen (N = 6) or injected into mice via the caudal veins (N = 6). For the subcutaneously injected mice, the tumor volume was evaluated every 7 days according to the following formula: V = ab2/2 (a: the longest diameter of the tumor; b: the shortest diameter of the tumor). After 30 days, the subcutaneously injected mice were euthanatized using an intraperitoneal injection of 1% pentobarbital (200 mg/kg).
