The Circadian Protein Period2 Suppresses mTORC1 Activity via Recruiting Tsc1 to mTORC1 Complex.

Cell Metab 2018 Dec 6. Epub 2018 Dec 6.

Key Laboratory of Metabolism and Molecular Medicine, the Ministry of Education, Department of Biochemistry and Molecular Biology, School of Basic Medical Sciences, Fudan University, Shanghai 200032, China. Electronic address:

Although emerging evidence indicates an important role of the circadian clock in modulating the diurnal oscillation of mammalian target of rapamycin complex 1 (mTORC1) signaling, the underlying molecular mechanism remains elusive. Here we show that Period2 (Per2), a core clock protein, functions as a scaffold protein to tether tuberous sclerosis complex 1 (Tsc1), Raptor, and mTOR together to specifically suppress the activity of mTORC1 complex. Due to the loss of its inhibition of mTORC1, Per2 deficiency significantly enhances protein synthesis and cell proliferation but reduces autophagy. Read More

Division of Neuroscience & Experimental Psychology, School of Biological Sciences, University of Manchester, Manchester, United Kingdom; Manchester Academic Health Science Centre, Manchester University NHS Foundation Trust, Greater Manchester Mental Health NHS Trust, Manchester, United Kingdom. Electronic address:

This chapter approaches the early development in autism spectrum disorder (ASD) through comparative study of some key monogenic syndromic models of ASD in humans. Using this method, as well as referring to relevant work in idiopathic ASD, we address three complimentary areas: (i) patterns of ASD behavioral phenotype expression across genetic syndromes, as a way of addressing gene-phenotype correlations; (ii) longitudinal developmental trajectories toward autism in early childhood, as a way of addressing developmental specificity; and (iii) experimental intervention trials, for treatment and mechanism discovery. The comparative approach does not highlight striking phenotypic specificity, but early studies were often limited and more methodologically sophisticated recent studies may suggest subtle distinctions.

Invasive monitoring after resection of epileptogenic neocortical lesions in multistaged epilepsy surgery in children.

Epilepsy Res 2018 Dec 19;148:48-54. Epub 2018 Sep 19.

Division of Pediatric Neurosurgery, Department of Surgery, Texas Children's Hospital and Department of Neurosurgery, Baylor College of Medicine, Houston, TX, USA.

Objective: Incomplete resection of neocortical epileptogenic foci correlates with failed epilepsy surgery in children. We often treat patients with neocortical epilepsy with a staged approach using invasive monitoring to localize the focus, resect the seizure onset zone, and, in select cases, post-resection invasive monitoring (PRM). We report the technique and the outcomes of children treated with staged surgery including PRM. Read More

The mTOR Independent Function of Tsc1 and FNIPs.

Trends Biochem Sci 2018 Dec 22;43(12):935-937. Epub 2018 Oct 22.

Department of Urology, SUNY Upstate Medical University, Syracuse, NY 13210, USA; Upstate Cancer Center, SUNY Upstate Medical University, Syracuse, NY 13210, USA; Department of Biochemistry and Molecular Biology, SUNY Upstate Medical University, Syracuse, NY 13210, USA. Electronic address:

New roles for Tsc1 and FNIP1/2 as regulators of the molecular chaperone Hsp90 were recently identified, demonstrating a broader cellular impact outside of AMPK-mTOR signaling. In studying the function of these proteins we must take a holistic view of the cell, instead of maintaining our focus on a single pathway. Read More

Using Bayesian methodology to explore the profile of mental health and well-being in 646 mothers of children with 13 rare genetic syndromes in relation to mothers of children with autism.

Orphanet J Rare Dis 2018 Oct 25;13(1):185. Epub 2018 Oct 25.

Cerebra Centre for Neurodevelopmental Disorders, School of Psychology, University of Birmingham, Birmingham, B15 2TT, UK.

Background: It is well documented that mothers of children with intellectual disabilities or autism experience elevated stress, with mental health compromised. However, comparatively little is known about mothers of children with rare genetic syndromes. This study describes mental health and well-being in mothers of children with 13 rare genetic syndromes and contrasts the results with mothers of children with autism. Read More

Mechanistic target of rapamycin (mTOR) promotes cell proliferation, growth, and survival and is overactivated in many tumors and central nervous system disorders. PQR620 (3) is a novel, potent, selective, and brain penetrable inhibitor of mTORC1/2 kinase. PQR620 (3) showed excellent selectivity for mTOR over PI3K and protein kinases and efficiently prevented cancer cell growth in a 66 cancer cell line panel. Read More
