Therapeutic Strategies in Fragile X Syndrome: From Bench to Bedside and Back.

ABSTRACT: Fragile X syndrome (FXS), an inherited intellectual disability often associated with autism, is caused by the loss of expression of the fragile X mental retardation protein. Tremendous progress in basic, preclinical, and translational clinical research has elucidated a variety of molecular-, cellular-, and system-level defects in FXS. This has led to the development of several promising therapeutic strategies, some of which have been tested in larger-scale controlled clinical trials. Here, we will summarize recent advances in understanding molecular functions of fragile X mental retardation protein beyond the well-known role as an mRNA-binding protein, and will describe current developments and emerging limitations in the use of the FXS mouse model as a preclinical tool to identify therapeutic targets. We will review the results of recent clinical trials conducted in FXS that were based on some of the preclinical findings, and discuss how the observed outcomes and obstacles will inform future therapy development in FXS and other autism spectrum disorders.

Therapeutic Strategies in the Fight against COVID-19: From Bench to Bedside.

Project description:In December 2019, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in China. This virus rapidly spread worldwide and was declared a global pandemic by the World Health Organization (WHO) in March 2020. High incidence, long incubation period, and diverse clinical signs of the disease posed a huge challenge globally. The efforts of health systems have been focused on repurposing existing drugs or developing innovative therapies to reduce the morbidity and mortality associated with SARS-CoV-2. In addition, most of the large pharmaceutical companies are intensely working on vaccine development to swiftly deliver safe and effective vaccines to prevent further spread of the virus. In this review, we will discuss the latest data on therapeutic strategies undergoing clinical trials. Additionally, we will provide a summary of vaccines currently under development.

Long QT syndrome - Bench to bedside.

Project description:Long QT syndrome (LQTS) is a cardiovascular disorder characterized by an abnormality in cardiac repolarization leading to a prolonged QT interval and T-wave irregularities on the surface electrocardiogram. It is commonly associated with syncope, seizures, susceptibility to torsades de pointes, and risk for sudden death. LQTS is a rare genetic disorder and a major preventable cause of sudden cardiac death in the young. The availability of therapy for this lethal disease emphasizes the importance of early and accurate diagnosis. Additionally, understanding of the molecular mechanisms underlying LQTS could help to optimize genotype-specific treatments to prevent deaths in LQTS patients. In this review, we briefly summarize current knowledge regarding molecular underpinning of LQTS, in particular focusing on LQT1, LQT2, and LQT3, and discuss novel strategies to study ion channel dysfunction and drug-specific therapies in LQT1, LQT2, and LQT3 syndromes.

Bedside to bench and back to bedside: Translational implications of targeted intervertebral disc therapeutics.

Project description:Spinal pain and associated disability is a leading cause of morbidity worldwide that has a strong association with degenerative disc disease (DDD). DDD can begin in early-late adolescence and has a variable course. Biologically based therapies to treat DDD face significant challenges posed by the unique milieu of the environment within the intervertebral discs. Many potential promising therapies are still in the early stages of development with a hostile microenvironment within the disc presenting unique challenges. The translational potential of this article: Patient selection, reasonable therapeutic goals, approach, and timing will need to be discerned in order to successfully translate potential therapeutics.

Has retinal gene therapy come of age? From bench to bedside and back to bench.

Project description:Retinal gene therapy has advanced considerably in the past three decades. Initial efforts have been devoted to comprehensively explore and optimize the transduction abilities of gene delivery vectors, define the appropriate intraocular administration routes and obtain evidence of efficacy in animal models of inherited retinal diseases (IRDs). Successful translation in clinical trials of the initial promising proof-of-concept studies led to the important milestone of the first approved product for retinal gene therapy in both US and Europe. The unprecedented clinical development observed during the last decade in the field is however highlighting new challenges that will need to be overcome to bring gene therapy to fruition to a larger patient population within and beyond the realm of IRDs.

Rett syndrome from bench to bedside: recent advances.

Project description:Rett Syndrome is a severe neurological disorder mainly due to de novo mutations in the methyl-CpG-binding protein 2 gene ( MECP2). Mecp2 is known to play a role in chromatin organization and transcriptional regulation. In this review, we report the latest advances on the molecular function of Mecp2 and the new animal and cellular models developed to better study Rett syndrome. Finally, we present the latest innovative therapeutic approaches, ranging from classical pharmacology to correct symptoms to more innovative approaches intended to cure the pathology.

From Bench to Bedside and Back: Improving the Safety of GalNAc-siRNA Conjugates Using GNA-Destabilized Seed-Pairing

Project description:Preclinical mechanistic studies have pointed towards RNAi-mediated off-target effects as a major driver of hepatotoxicity for GalNAc-siRNA conjugates. Here we demonstrate that a single glycol nucleic acid (GNA) modification can substantially reduce siRNA seed-mediated binding to off-target transcripts while maintaining on-target activity. In siRNAs with established off-target effects leading to hepatotoxicity, these Enhanced Stabilization Chemistry plus (ESC+) designs exhibit a substantially improved therapeutic window in rat. We utilized this strategy to improve the safety of ALN-HBV, which exhibited dose-dependent, transient, and asymptomatic alanine aminotransferase elevations in healthy volunteers.

Bedside Back to Bench: Building Bridges between Basic and Clinical Genomic Research.

Project description:Genome sequencing has revolutionized the diagnosis of genetic diseases. Close collaborations between basic scientists and clinical genomicists are now needed to link genetic variants with disease causation. To facilitate such collaborations, we recommend prioritizing clinically relevant genes for functional studies, developing reference variant-phenotype databases, adopting phenotype description standards, and promoting data sharing.

Insights From Atrial Fibrillation Genomics: From Bedside to Bench and Back Again.

Project description:From the bedside of patients contributing samples to large genome-wide association studies for atrial fibrillation (AF), over 100 AF risk loci have been identified. The top locus is near a gene implicated in pulmonary vein formation; the ostia of the pulmonary veins harbor initiating triggers of AF, and isolation of these areas is the cornerstone of ablation therapies for AF. Transcriptomic studies suggest that AF is associated with impaired or overwhelmed responses to cell stress. A dual risk model proposes that in genetically-susceptible individuals, inadequate transcriptional responses to stress predispose to AF in later life. Drugs targeting metabolic, oxidative, or protein handling stress may be novel upstream agents to bring back to the bedside for study in the prevention of AF.
