SCN8A activates MCF2L2. 9 / 9
| 9

reach
"All these results suggested that activation of STAT3 signaling was involved in TNF-α-induced Nav1.6 upregulation in DRG neurons."

reach
"TNF-alpha promotes the combination of p-STAT3/p300 and Scn8a promoter in DRG."

reach
"Here, to determine whether the activated STAT3 signaling transcriptionally regulated the expression of Nav1.6, we first observed the binding of STAT3 in the Scn8a promoter in DRG using a ChIP-PCR assay."

reach
"Moreover, our recent study shows that upregulation of Nav1.6 increased the DRG neuron excitability and contributed to the development of neuropathic pain [7]."

reach
"Moreover, IP and ChIP assays showed that L5-VRT enhanced the interaction between p-STAT3 and p300 and increased the recruitment of p-STAT3 and histone H4 acetylation on the Scn8a promoter in DRG."

reach
"However, it remains unknown whether activation of the TNF-α/STAT3 pathway mediates the Nav1.6 upregulation in DRG following lumbar 5 ventral root transection (L5-VRT)."

reach
"Suppression of STAT3 activation with local knockdown or inhibitor S3I-201 significantly attenuated H4 acetylation, and Nav1.6 upregulation in DRG, and relieved mechanical allodynia induced by L5-VRT."

reach
"Intraperitoneal injection of the TNF-α inhibitor thalidomide reduced the phosphorylation of STAT3 and decreased the recruitment of STAT3 and histone H4 hyper-acetylation in the Scn8a promoter, and subsequently attenuated Nav1.6 upregulation in DRG neurons and mechanical allodynia induced by L5-VRT."

reach
"The STAT3 activation mediated by TNF-alpha participates in Nav1.6 upregulation in DRG."
