Experiment 1 Reporting the m6A-centered Disease Response by This Target Gene				[1]
Response Summary	Theses findings reveal an epigenetic interplay mechanism in NPC senescence and IVD degeneration, presenting a critical pro-senescence role of ALKBH5 and m6A hypomethylation, highlighting the therapeutic potential of targeting the m6A/DNA (cytosine-5)-methyltransferase 3B (DNMT3B)/E4F1 axis for treating IVD degeneration.
Responsed Disease	Intervertebral disc degeneration [ICD-11: FA80]
Target Regulator	RNA demethylase ALKBH5 (ALKBH5)		ERASER	Regulator Info
Target Regulation	Down regulation
In-vitro Model	Nucleus pulposus cell (The NP tissues were cut into pieces after collection during surgery)

Experiment 1 Reporting the m6A-centered Disease Response by This Target Gene				[2]
Response Summary	Subsequent loss- and gain-of-function experiments reveal WTAP is increased in senescent nucleus pulposus cells, and significantly promotes Long intergenic non-protein coding RNA 657 (NORAD) m6A modification. This study shows interruption of NORAD m6A modification or the NORAD/PUMILIO/E2F3 axis could serve as a potential therapeutic target to inhibit the senescence of NPCs and development of intervertebral disc degeneration(IVDD).

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.
