m6A Modification:
m6A Regulator YTH domain-containing family protein 2 (YTHDF2) READER
m6A Target Circ_GPATCH2L
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type Non-coding RNA (ncRNA)
Epigenetic Regulator Circ_GPATCH2L circRNA View Details
Regulated Target Tripartite motif containing 28 (TRIM28) View Details
Crosstalk Relationship m6A  →  ncRNA Inhibition
Crosstalk Mechanism m6A regulators directly modulate the functionality of ncRNAs through specific targeting ncRNA
Crosstalk Summary m6A-methylated Circ_GPATCH2L is recognised and endoribonucleolytically cleaved by a YTHDF2-RPL10-RNase P/MRP complex to maintain the physiological state of nucleus pulposus cells, and then regulates DNA damage and apoptosis through Tripartite motif containing 28 (TRIM28) in intervertebral disc degeneration.
Responsed Disease Spinal pain ICD-11: ME84.2
Cell Process Cell apoptosis
In-vivo Model Briefly, the spine was exposed through an anterior midline transperitoneal approach, and L4/5 were punctured by a 33-gauge needle (Hamilton, Reno, NV). A total of 2 ×108 viral genome particles per mouse of Adv-sh-Scramble (5 ×1011 pfu/ml) or Adv-sh-circGPATCH2L (1 ×1011 pfu/ml) were injected into the indicated discs. After the operation, the incision was closed in a layered fashion, and the animals were allowed to move freely around their cages.
