MicroRNA-155 contributes to plexiform neurofibroma growth downstream of MEK

Oncogene, 2020
MicroRNAs (miRs) are small non-coding RNAs that can have large impacts on oncogenic pathways. Possible functions of dysregulated miRs have not been studied in neurofibromatosis type 1 (NF1) plexiform neurofibromas (PNFs).

Neurodevelopmental and Psychiatric Studies in Children and Adolescents With Neurofibromatosis Type I: A Comprehensive Scoping Review

American Journal of Medical Genetics Part B: Neuropsychiatric Genetics, EarlyView.
ABSTRACT A comprehensive synthesis of the broad range of neurodevelopmental and psychiatric manifestations in NF1 is needed to identify knowledge gaps and future directions for NF1 research. In the following scoping review, we identify and summarize the scope of research that examines neurodevelopmental and psychiatric manifestations, both as ...

Trametinib in Adults with Neurofibromatosis Type 1‐Related Symptomatic Plexiform Neurofibromas

Annals of Neurology, EarlyView.
Objective Mitogen‐activated protein kinase kinase inhibitors have shown promising results in treatment of plexiform neurofibromas in neurofibromatosis type 1 patients, but data in adults are limited. The aim of this phase 2 study was to investigate the efficacy and safety of trametinib in adults with neurofibromatosis type 1.

The Plexiform Neurofibroma Microenvironment [PDF]

Cancer Microenvironment, 2012
Dynamic interactions between tumorigenic cells and surrounding cells, including immunomodulatory hematopoietic cells, can dictate tumor initiation, progression, and transformation. Hematopoietic-stromal interactions underpin the plexiform neurofibroma, a debilitating tumor arising in individuals afflicted with Neurofibromatosis type 1 (NF1), a common ...

A case of portal hypertension by presumed as plexiform neurofibroma at the hepatic hilum [PDF]

Clinical and Molecular Hepatology, 2016
Neurofibromas can occur anywhere in the body, but they usually involve the head, neck, pelvis, and extremities. Abdominal visceral involvement is rare, and intrahepatic involvement is even less common.

A phase 2 study of trametinib for patients with pediatric glioma or plexiform neurofibroma with refractory tumor and activation of the MAPK/ERK pathway: TRAM-01

BMC Cancer, 2019
Pediatric low-grade gliomas (PLGG) are the most frequent brain tumors in children. Up to 50% will be refractory to conventional chemotherapy. It is now known that the majority of PLGG have activation of the MAPK/ERK pathway.

Meflin/ISLR is a meningeal cell‐specific marker involved in the development of meninges and meningioma progression

Brain Pathology, Volume 36, Issue 2, March 2026.
Mesenchymal stromal cell‐and fibroblast‐expressing Linx paralogue (Meflin) is expressed in embryonic meninges and contributes to meningeal homeostasis. In meningiomas, elevated Meflin correlates with higher grade and recurrence. Single‐cell RNA sequencing revealed a Meflin‐high tumor cell subset marked by reduced proliferation, WNT6 expression, and ...

Outcomes following definitive treatment of malignant peripheral nerve sheath tumor are significantly worse for patients with neurofibromatosis type 1: A Canadian Sarcoma Research and Clinical Collaboration study

Cancer, Volume 132, Issue 3, 1 February 2026.
Abstract Background Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas with a 5‐year survival rate of approximately 50%, secondary to their metastatic potential and resistance to therapy. MPNSTs can arise sporadically, as a late toxicity from therapeutic radiotherapy, or in patients with neurofibromatosis type 1 (NF1).
