Crosstalk Relationship Histone modification  →  m6A Inhibition
Crosstalk Mechanism Histone modification indirectly regulates m6A modification through downstream signaling pathways
Crosstalk Summary LncRNA Long intergenic non-protein coding RNA 657 (NORAD) could be modified by m6A due to an increase in WTAP, which was regulated by KDM5A-mediated Histone H3 lysine 4 trimethylation (H3K4me3) modification of the promoter. YTHDF2-mediated decay of NORAD is enhanced in senescent NPCs, and then deficiency of NORAD results in less sequestraion of PUMILIO proteins, contributing to the augmented activity of PUM1 and PUM2, thus repressing the expression of target E2F3 mRNAs and promoting the cellular senescence.
Responsed Disease Intervertebral disc degeneration ICD-11: FA80
In-vitro Model
Nucleus pulposus cells (NPCs) (Nucleus pulposus cells)
In-vivo Model After 50g male NORAD-KO or C57 mice at age of 8 weeks were anesthetized with 3% (w/v) pentobarbital (2 ml/kg) and grouped randomly, investigators blinded to the group allocation performed the experiment. The disc levels in rat tail (Co6/7, 7/8, and 8/9) were located by palpation on the coccygeal vertebrae and confirmed by trial radiography. Needles (33-G) were used to puncture the annulus fibrosus layer though the tail skin, in parallel to the end plates. To ensure that the needle did not penetrate too deeply , the length of the needle was pre-determined according to the dimensions of annulus fibrosus and the NP , which were measured in a preliminary experiment and found to be approximately 4 mm. Five kinds of solution were prepared for intradisc injection, including AA V vector, AAV containing shPUM1, AAV containing shPUM2 for Norad KO mice, AAV vector, AAV containing shE2F3, AAVcontaining OE-E2F3 for WT mice.
