Molecular and cellular characterization of a zebrafish optic pathway tumor line implicates glia-derived progenitors in tumorigenesis.

open access: yesPLoS ONE, 2014
In this study we describe the molecular and cellular characterization of a zebrafish mutant that develops tumors in the optic pathway. Heterozygous Tg(flk1:RFP)is18 transgenic adults develop tumors of the retina, optic nerve and optic tract.

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

open access: yesAdvanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

Whole-body MRI evaluation in neurofibromatosis type 1 patients younger than 3 years old and the genetic contribution to disease progression

open access: yesOrphanet Journal of Rare Diseases, 2022
Background Neurofibromatosis type 1 (NF1) is a common human genetic disease with age-dependent phenotype progression. The overview of clinical and radiological findings evaluated by whole-body magnetic resonance imaging (WBMRI) in NF1 patients  3 cm in ...

A Multidimensional Engineering Strategy Reprograms Microglia via Targeted and Sustained‐Release Extracellular Vesicles for Spinal Cord Injury Repair

open access: yesAdvanced Science, EarlyView.
A multifunctional EV‐based nanoplatform (Ang‐TEVs@Gel) was engineered via preconditioning, surface targeting, and ROS‐responsive hydrogel encapsulation to reprogram microglia. This system restored autophagy via miR‐664a‐3p/PIK3CA axis, cleared myelin debris, resolved neuroinflammation, and promoted axon remyelination, ultimately achieving robust motor ...

Loss of CYLD on Chromosome 16q Impairs Homologous Recombination and Genomic Stability Through TIRR Degradation

open access: yesAdvanced Science, EarlyView.
Chromosome 16q loss drives genomic instability through disruption of the CYLD–TIRR–53BP1 axis. CYLD preserves homologous recombination by stabilizing TIRR and limiting 53BP1 accumulation at DNA double‐strand breaks. CYLD deficiency redirects repair toward error‐prone non‐homologous end joining, promotes mutational burden and homologous recombination ...

Sporadic Optic Nerve Glioma Causing Bitemporal Hemianopia

open access: yesTNOA Journal of Ophthalmic Science and Research
Primary tumours of the optic nerve are relatively rare. Optic nerve gliomas are usually seen in children under the age of 10 and present with gradual vision loss followed by proptosis. A 19-year-old female presented to our neuro-ophthalmology clinic with

Estrogen Induces IL-1β to Mediate Retinal Ganglion Cell Loss in Murine Optic Glioma

open access: yes, 2023
Optic pathway glioma (OPG) is a low-grade astrocytoma seen in 15-20% of children with the neurofibromatosis type 1 (NF1) cancer predisposition syndrome. While not fatal, 30-50% of children with NF1-OPG exhibit retinal ganglion cell (RGC) death and vision

Natural Product Toosendanin Suppresses the Malignant Development of Skin Melanoma by Targeting BNC2 for Degradation

open access: yesAdvanced Science, EarlyView.
BNC2 exhibits context‐dependent opposing functions across multiple cancer types. This study reveals BNC2 as an oncogenic driver of melanoma proliferation and metastasis through transcriptional activation of PIK3CA. The natural compound TSN simultaneously degrades BNC2 and its oncogenic partner SMAD3 via CRBN‐dependent ubiquitination.

Serial MRIs provide novel insight into natural history of optic pathway gliomas in patients with neurofibromatosis 1

open access: yesOrphanet Journal of Rare Diseases, 2018
Background Optic pathway gliomas (OPGs) are present in 20% of children with neurofibromatosis 1 (NF1) but are less frequently observed in adults. Our goal was to determine the natural history of OPGs in children and adults with NF1.
