The molecular basis of T cell acute lymphoblastic leukemia [PDF]

open access: yes, 2012
T cell acute lymphoblastic leukemias (T-ALLs) arise from the malignant transformation of hematopoietic progenitors primed toward T cell development, as result of a multistep oncogenic process involving constitutive activation of NOTCH signaling and ...

Optic nerve sheath meningioma exhibits neural niche‐associated transcriptomic features and rare copy number variation‐linked evolution

open access: yesBrain Pathology, EarlyView.
Optic nerve sheath meningiomas are typically NF2‐intact with few copy number alterations and are generally clinically indolent. Rare aggressive recurrences are associated with progressive accumulation of copy number variations, including CDKN2A/B homozygous deletion, 1q gain, and 14q loss.

Somatic neurofibromatosis type 1 (NF1) inactivation characterizes NF1-associated pilocytic astrocytoma [PDF]

open access: yes, 2012
Low-grade brain tumors (pilocytic astrocytomas) arising in the neurofibromatosis type 1 (NF1) inherited cancer predisposition syndrome are hypothesized to result from a combination of germline and acquired somatic NF1 tumor suppressor gene mutations ...

Losartan Enhances Radiosensitivity by Reversing Immunosuppressive Tumor Microenvironment Induced by Radiotherapy in TNBC

open access: yesCancer Science, EarlyView.
Our study demonstrates that the angiotensin receptor blocker losartan enhances the efficacy of radiotherapy in triple‐negative breast cancer by reversing the immunosuppressive tumor microenvironment. Losartan reprograms tumor‐associated macrophages, inhibits myeloid‐derived suppressor cell function, and boosts CD8+ T‐cell activity.

Pheochromocytomas and paragangliomas: clinical and genetic approaches

open access: yesFrontiers in Endocrinology, 2015
Pheochromocytomas (PCCs) and paragangliomas (PGLs) are neuroendocrine tumours derived from the chromafin tissue. Diagnosis of these tumours is extremely important as they are linked to the hypertension syndrome with great cardiovascular morbidity and ...

Deep‐Intronic Variant in RUNX2 Causing Pseudo‐Exon Inclusion in a Family With Cleidocranial Dysplasia

open access: yesClinical Genetics, EarlyView.
A deep‐intronic single nucleotide variant in RUNX2 causes the characteristic clinical features of cleidocranial dysplasia (CCD) in a family via pseudo‐exon inclusion into the mRNA. The pseudo‐exon contains a premature stop codon and triggers mRNA decay, which results in RUNX2 haploinsufficiency, the known disease mechanism.

Isolated Pheochromocytoma in a 73-Year-Old Man With No Clinical Manifestations of Type 1 Neurofibromatosis Carrying an Unsuspected Deletion of the Entire NF1 Gene

open access: yesFrontiers in Endocrinology, 2019
Pheochromocytomas (PHEOs) are a rare cause of endocrine hypertension that requires genetic counseling since at least 30% of PHEOs are associated with a germline mutation in a susceptibility gene.

Neurofibromatosis type 1: Modeling CNS dysfunction [PDF]

open access: yes, 2012
Neurofibromatosis type 1 (NF1) is the most common monogenic disorder in which individuals manifest central nervous system (CNS) abnormalities. Affected individuals develop glial neoplasms (optic gliomas, malignant astrocytomas) and neuronal dysfunction ...

Neonates born at term with periventricular haemorrhagic infarction: Risk factors and clinical presentation

open access: yesDevelopmental Medicine &Child Neurology, EarlyView.
This case series describes infants born near term with periventricular hemorrhagic infarction (PVHI), highlighting seizures as a common early symptom. Neonatal complications during delivery and pro‐thrombotic genetic mutations were slightly more common. MRI‐classified involvement was predominantly in the caudate vein territory.
