Response Summary	FTO contributes to neuropathic pain through stabilizing nerve injury-induced upregulation of Histone-lysine N-methyltransferase EHMT2 (G9a), a neuropathic pain initiator, in primary sensory neurons.

In-vivo Model	After the animal was anesthetized with isoflurane, a midline incision in the lower lumbar back region was made and the lumbar articular process was exposed and then removed. The exposed DRG was injected with viral solution (1-1.5 ul in rats and 0.5-1 ul in mice) through a glass micropipette connected to a Hamilton syringe. The pipette was retained for 10 min after injection. Animals showing signs of paresis or other abnormalities were excluded. The injected DRGs were stained with hematoxylin/eosin to examine the integrity of their structure and whether they contained visible leukocytes.

Response Summary	FTO was colocalized with Matrix metalloproteinase-24 (MMP24) in spinal neurons and shown increased binding to the Mmp24 mRNA in the spinal cord after SNL. SNL promoted the m6A eraser FTO binding to the Mmp24 mRNA, which subsequently facilitated the translation of MMP24 in the spinal cord, and ultimately contributed to neuropathic pain genesis.

In-vivo Model	Mice were anesthetized with Nembutal. The lower back was dissected until the transverse lumbar process was exposed. After the process was removed, the underneath L4 spinal nerve was ligated with a silk 6-0 thread. A slight distal location was chosen for transection around the ligation site. Subsequent layers of muscle and skin were closed. The sham groups undertook identical procedures, but without the transection or ligature of the corresponding nerve. The intraspinal injection was performed as described previously. In short, after anesthetized with Nembutal, mice underwent hemilaminectomy at the L1-L2 vertebral segments. The intraspinal injection was carried out ipsilaterally on the left side. By using a glass micropipette, each animal received two injections (5 × 105 TU per injection, 0.8 mm from the midline, 0.5 mm apart in rostrocaudal axis, 0.5 mm deep) of lentivirus following the L3-L4 dorsal root entry zone after exposure of spinal cord. The tip of glass micropipette should reach a depth of lamina II-IV of the spinal cord. Finally, the dorsal muscle and skin were sutured layer by layer.

Response Summary	Enhanced METTL3 promoted the m6A methylation in total RNAs and inhibited neuropathic pain (NP) progression. Mechanistically, METTL3 accelerated microRNA 150 (MIR150) maturation via mediating m6A methylation of primiR-150 at locus 498, cooperating with the "m6A reader" YTHDF2. Therefore, the METTL3/miR-150/BDNF pathway is a promising therapeutic target for NP patients.

In-vitro Model	RN-sc (The rat neuron cell line RN-sc was purchased from ScienCell (ScienCell Research Laboratories Inc. catlog. #R1590, Carlsbad, CA).)
In-vivo Model	Based on our study design, the enrolled animals were blindingly grouped and received the following treatments: (1)Sham-NC vectors, (2)Sham-sh-METTL3, (3)Sham-sh-METTL3 + miR-150, (4)Sham-sh-METTL3 + Lv-YTHDF2, (5)Sham-sh-METTL3 + sh-BDNF, (6)Sham-anti-miR150, (7)Sham-anti-miR150+sh-BDNF, (8)SNI-Lv-METTL3, (9)SNI-Lv-METTL3 + anti-miR-150, (10)SNI-Lv-METTL3 + sh-YTHDF2, (11)SNI-Lv-METTL3 + Lv-BDNF, (12)SNI-miR150, (13)SNI-miR150+Lv-BDNF. The pain behaviors were detected in the respective time points and the expressions of METTL3 and miR-150 were determined at day 14 after the rats were sacrificed.
