    The genomic landscape of tuberous sclerosis complex.
    Nat Commun 2017 Jun 15;8:15816. Epub 2017 Jun 15.
    Center for Cancer and Cell Biology, Van Andel Research Institute, 333 Bostwick Avenue NE, Grand Rapids, Michigan 49503, USA.
    Tuberous sclerosis complex (TSC) is a rare genetic disease causing multisystem growth of benign tumours and other hamartomatous lesions, which leads to diverse and debilitating clinical symptoms. Patients are born with TSC1 or TSC2 mutations, and somatic inactivation of wild-type alleles drives MTOR activation; however, second hits to TSC1/TSC2 are not always observed. Here, we present the genomic landscape of TSC hamartomas. Read More

    Genomic rearrangements in sporadic lymphangioleiomyomatosis: an evolving genetic story.
    Mod Pathol 2017 Jun 23. Epub 2017 Jun 23.
    Departments of Pulmonary and Critical Care Medicine, Mayo Clinic, Rochester, MN, USA.
    Sporadic lymphangioleiomyomatosis is a progressive pulmonary cystic disease resulting from the infiltration of smooth muscle-like lymphangioleiomyomatosis cells into the lung. The migratory/metastasizing properties of the lymphangioleiomyomatosis cell together with the presence of somatic mutations, primarily in the tuberous sclerosis complex gene (TSC2), lead many to consider this a low-grade malignancy. As malignant tumors characteristically accumulate somatic structural variations, which have not been well studied in sporadic lymphangioleiomyomatosis, we utilized mate pair sequencing to define structural variations within laser capture microdissected enriched lymphangioleiomyomatosis cell populations from five sporadic lymphangioleiomyomatosis patients.

    Hum Mol Genet 2017 Jun 14. Epub 2017 Jun 14.
    Department of Chemistry, Biology and Biotechnology, University of Perugia, Via del Giochetto, 06122 Perugia, Italy.
    Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disorder caused by mutations in either of two genes, TSC1 or TSC2, resulting in the constitutive activation of the mammalian target of rapamycin complex 1 (mTORC1). mTOR inhibitors are now considered the treatment of choice for TSC disease. A major pathological feature of TSC is the development of subependymal giant cell astrocytomas (SEGAs) in the brain. Read More

    Primary cilia arebiophysically-sensitive organelles responsible for sensing fluid-flow and transducing this stimulus into intracellular responses. Previous studies have shown that the primary cilia mediate flow-induced calcium influx, and sensitivity of cilia function to flow is correlated to cilia length. Cells with abnormal cilia length or function can lead to a host of diseases that are collectively termed as ciliopathies. Read More

    [Epileptic encephalopathies in infancy. How do we treat them? Does the aetiology influence the response to treatment?]
    Rev Neurol 2017 May;64(s03):S71-S75
    Hospital Universitario Virgen de las Nieves, 18013 Granada, Espana.
    Introduction: Resistance to treatments is a common feature of Ohtahara, Aicardi, West and Dravet syndromes, as well as malignant migrating epilepsy in infancy.

    Aims: To update the therapeutic management and to analyse whether the aetiology somehow determines the treatment.

    Development: Convulsive seizures in the first year of life may be due to a potentially treatable aetiology, which makes it essential to carry out a complete evaluation so as to be able to begin, as early as possible, the most suitable and the non-specific symptomatic treatments to control the seizures, which prevents or minimises their deleterious effects.

    [Epileptic encephalopathies].
    Rev Neurol 2017 May;64(s03):S45-S48
    Hospital Torrecardenas, 04009 Almeria, Espana.
    According to the International League Against Epilepsy's (ILAE) Commission on Classification and Terminology, the term 'epileptic encephalopathy' reflects the notion that epileptic activity in itself can contribute to the genesis of severe cognitive or behavioural disabilities, beyond what could be expected from the pathology underlying the epilepsy. However, in many cases it is difficult to define the boundary between the relative contribution of the epileptic seizures and the underlying cause in the genesis of cognitive deficits. Some epileptic syndromes, such as those of West, Lennox-Gastaut or Dravet, are associated to a high probability of encephalopathic traits. Read More

    Assembly of the U5 snRNP component PRPF8 is controlled by the HSP90/R2TP chaperones.
    J Cell Biol 2017 Jun 17;216(6):1579-1596. Epub 2017 May 17.
    Institut de Génétique Moléculaire de Montpellier, Centre National de la Recherche Scientifique, University of Montpellier, 34293 Montpellier, France
    Splicing is catalyzed by the spliceosome, a complex of five major small nuclear ribonucleoprotein particles (snRNPs). The pre-mRNA splicing factor PRPF8 is a crucial component of the U5 snRNP, and together with EFTUD2 and SNRNP200, it forms a central module of the spliceosome. Using quantitative proteomics, we identified assembly intermediates containing PRPF8, EFTUD2, and SNRNP200 in association with the HSP90/R2TP complex, its ZNHIT2 cofactor, and additional proteins.

    p62/SQSTM1 Cooperates with Hyperactive mTORC1 to Regulate Glutathione Production, Maintain Mitochondrial Integrity, and Promote Tumorigenesis.
    Cancer Res 2017 Jun 16;77(12):3255-3267. Epub 2017 May 16.
    Pulmonary and Critical Care Medicine, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School, Boston, Massachusetts.
    p62/sequestosome-1 (SQSTM1) is a multifunctional adaptor protein and autophagic substrate that accumulates in cells with hyperactive mTORC1, such as kidney cells with mutations in the tumor suppressor genes tuberous sclerosis complex (TSC)1 or TSC2. Here we report that p62 is a critical mediator of TSC2-driven tumorigenesis, as Tsc2(+/-) and Tsc2f/f Ksp-CreERT2(+) mice crossed to p62(-/-) mice were protected from renal tumor development. Metabolic profiling revealed that depletion of p62 in Tsc2-null cells decreased intracellular glutamine, glutamate, and glutathione (GSH). Read More

    Division of Neurology, Department of Pediatrics, Cincinnati Children's Hospital Medical Center, Cincinnati, Ohio. Electronic address:
    Background: Subependymal giant cell astrocytomas (SEGA) are slow-growing tumors, which can cause obstructive hydrocephalus in patients with tuberous sclerosis complex (TSC). These tumors require routine surveillance with magnetic resonance imaging. Current consensus guidelines recommend treatment of asymptomatic SEGAs with an mechanistic target of rapamycin (mTOR) inhibitor because these medications have demonstrated efficacy and safety in multiple prospective clinical trials.

    Background: Seizures are a common early presentation in infants with tuberous sclerosis complex (TSC) and can be preceded by electrographic changes on electroencephalography (EEG) before clinical seizure onset. A limited number of studies have addressed the initial EEG findings in TSC and the outcome of early treatment with antiepileptic medication prior to clinical seizure onset.

    Methods: We describe two infants with tuberous sclerosis complex whose surveillance EEG showed focal seizures that were not previously recognized by caregivers. Read More

    Chordoma Occurs in Young Children With Tuberous Sclerosis.
    J Neuropathol Exp Neurol 2017 Jun;76(6):418-423
    From the Department of Pediatrics, University of Colorado Denver, Aurora, Colorado (NAD, TL, ML, JMM-L); Morgan Adams Foundation Pediatric Brain Tumor Research Program, Children's Hospital Colorado, Aurora, Colorado (NAD, JMM-L); Department of Neurology (TL, BKK-D); Department of Radiology (IN); Department of Neurosurgery (MHH, BKK-D); and Department of Pathology, University of Colorado Denver, Aurora, Colorado (BKK-D).
    Chordomas are rare bony neoplasms usually unassociated with a familial tumor predisposition syndrome. The peak incidence of this midline axial skeletal tumor is in adulthood but when very young children are affected, consideration should be given to occurrence within the tuberous sclerosis (TS) complex, especially when presenting in neonates <3 months of age. To call attention to this association, we present a brachyury-immunopositive chordoma occurring in the skull base of a 2-month-old male infant who was later realized to have metastases to the subcutaneous tissues and lungs, as well as rhabdomyoma of the heart and renal cysts/angiomyolipomas, that is, characteristic features of the TS complex.
