Crosstalk ID
M6ACROT05813
[1]
m6A modification KCNQ1OT1 KCNQ1OT1 METTL14 Methylation : m6A sites Direct Enhancement Non-coding RNA KCNQ1OT1 miR-7-5p  lncRNA       miRNA   circRNA
m6A Modification:
m6A Regulator Methyltransferase-like 14 (METTL14) WRITER
m6A Target KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type Non-coding RNA (ncRNA)
Epigenetic Regulator KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1) LncRNA View Details
Regulated Target hsa-miR-7-5p View Details
Crosstalk Relationship m6A  →  ncRNA Enhancement
Crosstalk Mechanism m6A regulators directly modulate the functionality of ncRNAs through specific targeting ncRNA
Crosstalk Summary METTL14 promotes doxorubicin-induced cardiomyocyte ferroptosis by regulating the KCNQ1 opposite strand/antisense transcript 1 (KCNQ1OT1)-hsa-miR-7-5p-TFRC axis.
Responsed Drug Doxorubicin
Cell Process Ferroptosis
In-vitro Model
AC16 [Human hybrid cardiomyocyte] Normal Homo sapiens CVCL_4U18
In-vivo Model Male Sprague-Dawley rats (6-8 weeks old; weighed from 210 to 230 g) were purchased from HFK Bioscience Co. Ltd. They were housed under standard laboratory conditions. Rats were randomly assigned to four groups (n = 6 per group). The first was the control group, which were treated daily with 0.5 ml of 0.9% saline by intraperitoneal injection for 14 days, and there were three DOX model groups, which were treated three times weekly with 2.5 mg/kg of DOX by intraperitoneal injection for 14 weeks. At day 14, mice in the DOX model groups were infected through an intramyocardial injection of either control shNC or shMettl14 (1 × 109 titer) at three distinct locations in the left ventricular free wall three times a week for 2 weeks, and they were treated daily with 30 mg/kg of ferroptosis inducer erastin (MedChemExpress, USA) through intragastric administration or vehicle control (Saline) for 2 weeks.
