Transcriptomic signature of painful human neurofibromatosis type 2 schwannomas
Annals of Clinical and Translational Neurology, 2021 Schwannomas are benign neoplasms that can cause gain‐ and loss‐of‐function neurological phenotypes, including severe, intractable pain. To investigate the molecular mechanisms underlying schwannoma‐associated pain we compared the RNA sequencing profile ...
