Transcriptional landscape of neuronal and cancer stem cells [PDF]

, 2013
Tumor mass is composed by heterogeneous cell population including a subset of “cancer stem cells” (CSC). Oncogenic signals foster CSC by transforming tissue stem cells or by reprogramming progenitor/differentiated cells towards stemness.

A Smo/Gli multitarget hedgehog pathway inhibitor impairs tumor growth [PDF]

, 2019
Pharmacological Hedgehog (Hh) pathway inhibition has emerged as a valuable anticancer strategy. A number of small molecules able to block the pathway at the upstream receptor Smoothened (Smo) or the downstream effector glioma-associated oncogene 1 (Gli1)

FTY720 Decreases Tumorigenesis in Group 3 Medulloblastoma Patient-Derived Xenografts

Scientific Reports, 2018
Group 3 tumors account for 28% of medulloblastomas and have the worst prognosis. FTY720, an immunosuppressant currently approved for treatment of multiple sclerosis, has shown antitumor effects in several human cancer cell lines.

PRC2 disruption in cerebellar progenitors produces cerebellar hypoplasia and aberrant myoid differentiation without blocking medulloblastoma growth

Acta Neuropathologica Communications, 2023
We show that Polycomb Repressive Complex-2 (PRC2) components EED and EZH2 maintain neural identity in cerebellar granule neuron progenitors (CGNPs) and SHH-driven medulloblastoma, a cancer of CGNPs.

The cell of origin dictates the temporal course of neurofibromatosis-1 (Nf1) low-grade glioma formation. [PDF]

, 2017
Low-grade gliomas are one of the most common brain tumors in children, where they frequently form within the optic pathway (optic pathway gliomas; OPGs).

Citron Kinase Deficiency Leads to Chromosomal Instability and TP53-Sensitive Microcephaly [PDF]

, 2017
Mutations in citron (CIT), leading to loss or inactivation of the citron kinase protein (CITK), cause primary microcephaly in humans and rodents, associated with cytokinesis failure and apoptosis in neural progenitors.

The miR-139-5p regulates proliferation of supratentorial paediatric low-grade gliomas by targeting the PI3K/AKT/mTORC1 signalling [PDF]

, 2018
Paediatric low-grade gliomas (pLGGs) are a heterogeneous group of brain tumours associated with a high overall survival: however, they are prone to recur and supratentorial lesions are difficult to resect, being associated with high percentage of disease

Recurrent Cerebellar Desmoplastic/Nodular Medulloblastoma in Cerebrospinal Fluid (CSF) in the Elderly. A Cytologic Diagnosis

Romanian Journal of Internal Medicine, 2016
Desmoplastic medulloblastoma is a rare subtype of medulloblastoma in childhood and more rare in adults. Cerebrospinal fluid (CSF) occurrence is frequent and important for treatment and prognosis.
