The reelin signaling protein and its downstream components have been associated with synaptic plasticity and neurotransmission. The reelin signaling pathway begins with the binding of reelin to the transmembrane lipoprotein receptor apolipoprotein E receptor 2 (ApoER2), which in turns induces the sequential cleavage of ApoER2 by the sequential action of α- and γ-secretases. Using conditional-kn...

Reelin is an extracellular matrix-associated protein important in the regulation of neuronal migration during cerebral cortical development. Point mutations in the RELN gene have been shown to cause an autosomal recessive human brain malformation termed lissencephaly with cerebellar hypoplasia (LCH). Recent work has raised the possibility that reelin may also play a pathogenic role in other neu...

This paper reviews our present knowledge of the role of the one-carbon cycle in mood disorder and schizophrenia with particular attention to S-adenosyl methionine (SAM). After an historical introduction the clinical data is first reviewed of the anti-depressant action of SAM, in particular a survey of double blind placebo-controlled trials. Then follows an account of the biochemical parameters ...

The reelin gene is a strong candidate in the etiology of several psychiatric disorders such as schizophrenia, major depression, bipolar disorders, and autism spectrum disorders. Most of these diseases are accompanied by cognitive and executive-function deficits associated with prefrontal dysfunctions. Mammalian prefrontal cortex (PFC) development is characterized by a protracted postnatal matur...

Cryptorchidism refers to incomplete descend of the testes into the scrotum with the testes located in the normal tracts. The incident is 3-5% among infants born at term. The complications are infertility and testicular cancer. Cryptorchidism has a multifactorial aetiology and the role of exon 13 lgr8 gene polymorphism remains unclear. This study aims to find the frequency polymorphism of exon 1...

Introduction Reelin, a gigantic extracellular glycoprotein, plays a central role in cortical layer formation during mammalian brain development. Reelin was originally identified as a gene product absent in reeler mice exhibiting malformations of the cerebral cortex. Reelin acts on migrating neuronal precursors, and regulates correct cell positioning in the cortex and other brain structures. It ...

die-back disease caused by paecilomyces variotti is one of the most destructive diseases of pistachio in iran. in this study, genetic diversity of paecilomyces variotti isolates was investigated with ssr marker, using six primers pairs. sampling was done from pistachio gardens in different geographical zones of kerman province during summer 2013. various fungal isolates were isolated from infec...

Reelin is an extracellular signaling protein synthesized by Cajal-Retius cells in utero and early after birth, its presence being signaled in adult life too. Reelin acts on its receptors, VLDLR and ApoER2, acting on cytoskeleton, controlling migration and subsequently positioning and stabilizing the cortical neurons. We investigated the reelin presence and its receptors, VLDLR and ApoER2, in me...

Abstract. Aguilar KEV, Vivas AYS, Acosta-López C. 2023. Genetic variation of Limnophora marginata Stein, 1904 (Diptera: Muscidae), associated with an altitudinal gradient in Pedro Moncayo Canton, Pichincha, Ecuador. Biodiversitas 24: 269-275. Analyzing heterogeneity insect populations is relevant to understanding its biology. Thus, we analyzed the genetic variability two “hunter-flies”, Tocachi...

background : the main function of the pineal hormone melatonin which is mediated via its two receptors, mtnr1a and mtnr1b, is to mediate dark signals in addition to anti-oxidation, immune system enhancement, protection from radiation, and anti-cancer functions. a common single nucleotide polymorphism in the mtnr1b gene is rs#10830963, which is well known as a risk factor for type 2 diabetes mel...
