Moderate the MAOA-L Allele Expression with CRISPR/Cas9 System

Nelwan 4 Department of Animal Science – Other 5 Nelwan Institution for Human Resource Development 6 Jl. A. Yani No. 24 7 Palu, Sulawesi Tengah, Indonesia 8 Email: [email protected] 9 Abstract: Antisocial behavior is a behavior disorder inherited according to the inheritance of X-linked 10 chromosome. Mutations in the MAOA gene can cause different behaviors in humans. These can comprise 11 violent behavior or antisocial behavior. Low MAOA (MAOA-L) allele activity can cause antisocial 12 behavior in both healthy and unhealthy people. Antisocial from healthy males can originate from 13 maltreatment during childhood. There are no drugs for the treatment of antisocial behavior permanently 14 at this time. MAOA inhibitor can reverse antisocial behavior in animal models. To cure antisocial 15 behavior in the future, the CRISPR/Cas9 system in combination with iPSCs or ssODN methods for 16 instance can be used. This system has succeeded to correct erroneous segments in the F8 gene and F9 17 gene. Both genes occupy the X chromosome. The MAOA gene also occupies the X chromosome. It seems 18 that CRISPR/Cas9 system may be a beneficial tool to edit erroneous segments in the MAOA gene to treat 19 antisocial behavior. 20 Keywords: advanced therapy, aggressive, antisocial, behavior, MAOA. 21 22 1.

Abstract The increased speed and decreasing cost of sequencing, along with an understanding of the clinical relevance of emerging information for patient management, has led to an explosion of potential applications in healthcare. Cur- rently, SNP arrays and Next-Generation Sequencing (NGS) technologies are relatively new techniques used to scan genomes for gains and losses, losses of heterozygosity (LOH), SNPs, and indel variants as well as to perform com- plete sequencing of a panel of candidate genes, the entire exome (whole exome sequencing) or even the whole ge- nome. As a result, these new high-throughput technologies have facilitated progress in the understanding and diagnosis of genetic syndromes and cancers, two disorders traditionally considered to be separate diseases but that can share causal genetic alterations in a group of developmental disorders associated with congenital malformations and cancer risk. -

A major diagnostic clue is the characteristic neuroinflammatory parieto-occipital white matter lesions on magnetic resonance imaging. This study reports a 5-year 10-month old boy presenting with generalized skin hyperpigmentation since 3 years of age. Over the past 9 months, he had developed right-sided hemiparesis and speech and behavioral abnormalities, which had progressed over 5 months to bilateral hemiparesis. Retrospective analyses of serial brain magnetic resonance images revealed an unusual pattern of lesions involving the internal capsules, corticospinal tracts in the midbrain and brainstem, and cerebellar white matter. The clinical diagnosis of childhood cerebral adrenoleukodystrophy was confirmed by elevated basal levels of adrenocorticotropin hormone and plasma very long chain fatty acid levels. Additionally, sequencing of the ABCD1 gene revealed a novel mutation. -

Clinical Issues in Neonatal Care

Chapman , MD, PhD ABSTRACT Background: Inherited metabolic disorders (IMDs) are individually rare but collectively common disorders that frequently require rapid or urgent therapy. Purpose: This article provides a generalized approach to IMDs, as well as some investigations and safe therapies that may be initiated pending the metabolic consult. Methods/Search Strategy: An overview of the research supporting management strategies is provided. In addition, the newborn metabolic screen is reviewed. Findings/Results: Caring for infants with IMDs can seem difficult because each of the types is rarely seen; however, collectively the management can be seen as similar. Implications for Practice: When an IMD is suspected, a metabolic specialist should be consulted for expert advice regarding appropriate laboratory investigations and management. Because rapid intervention of IMDs before the onset of symptoms may prevent future irreversible sequelae, each abnormal newborn screen must be addressed promptly. Implications for Research: Management can be difficult. Research in this area is limited and can be difficult without multisite coordination since sample sizes of any significance are difficult to achieve. Key Words: -

Liver Glucose Metabolism in Humans
Biosci. Rep. (2016) / 36 / art:e00416 / doi 10.1042/BSR20160385 Liver glucose metabolism in humans Mar´ıa M. Adeva-Andany*1, Noemi Perez-Felpete*,´ Carlos Fernandez-Fern´ andez*,´ Cristobal´ Donapetry-Garc´ıa* and Cristina Pazos-Garc´ıa* *Nephrology Division, Hospital General Juan Cardona, c/ Pardo Bazan´ s/n, 15406 Ferrol, Spain Synopsis Information about normal hepatic glucose metabolism may help to understand pathogenic mechanisms underlying obesity and diabetes mellitus. In addition, liver glucose metabolism is involved in glycosylation reactions and con- nected with fatty acid metabolism. The liver receives dietary carbohydrates directly from the intestine via the portal vein. Glucokinase phosphorylates glucose to glucose 6-phosphate inside the hepatocyte, ensuring that an adequate flow of glucose enters the cell to be metabolized. Glucose 6-phosphate may proceed to several metabolic path- ways. During the post-prandial period, most glucose 6-phosphate is used to synthesize glycogen via the formation of glucose 1-phosphate and UDP–glucose. Minor amounts of UDP–glucose are used to form UDP–glucuronate and UDP– galactose, which are donors of monosaccharide units used in glycosylation. A second pathway of glucose 6-phosphate metabolism is the formation of fructose 6-phosphate, which may either start the hexosamine pathway to produce UDP-N-acetylglucosamine or follow the glycolytic pathway to generate pyruvate and then acetyl-CoA. Acetyl-CoA may enter the tricarboxylic acid (TCA) cycle to be oxidized or may be exported to the cytosol to synthesize fatty acids, when excess glucose is present within the hepatocyte. Finally, glucose 6-phosphate may produce NADPH and ribose 5-phosphate through the pentose phosphate pathway. -

These disorders can be divided into metabolic and developmental categories based on their molecular etiologies. Metabolic megalencephalies are mostly caused by genetic defects in cellular metabolism, whereas developmental megalencephalies have recently been shown to be caused by alterations in signaling pathways that regulate neuronal replication, growth, and migration. These disorders often lead to epilepsy, developmental disabilities, and Keywords behavioral problems; specific disorders have associations with overgrowth or abnor- ► megalencephaly malities in other tissues.
