Upregulated conserved circRNA cRps6kb1 in dorsal root ganglion neurons is linked to diabetic neuropathic pain, with blocking it reducing Nt3/proNT3 and CCL2.
- Why it matters: Conventional analgesics poorly manage diabetic neuropathic pain, and the mechanism connecting diabetes to DRG neurotrophin and chemokine changes is unclear.
- What they did: They measured cRps6kb1 in multiple mouse models of type 1 and type 2 diabetes and in human donors with DNP, then used cRps6kb1 inhibition or mimicry and high-glucose DRG neuron cultures.
- The result: cRps6kb1 inhibition attenuated DRG Nt3, proNT3, CCL2 expression and nociceptive hypersensitivity in streptozotocin type 1 DM and high-fat diet type 2 DM, while mimicry induced DNP-like symptoms; mechanistically, cRps6kb1 competes with the Nt3 3′-UTR for PUM2 binding to enhance Nt3 translation and stability.
