Amyloid Transthyretin Cardiomyopathy in Elderly Patients With Aortic Stenosis Undergoing Transcatheter Aortic Valve Implantation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023
Background The prevalence of calcific aortic stenosis and amyloid transthyretin cardiomyopathy (ATTR‐CM) increase with age, and they often coexist. The objective was to determine the prevalence of ATTR‐CM in patients with severe aortic stenosis and ...

Amyloid polyneuropathy caused by wild‐type transthyretin [PDF]

, 2015
IntroductionAmyloidosis derived from transthyretin (TTR) molecules is typically caused by mutations of the TTR gene.MethodsWe describe an elderly patient with a severe length-dependent polyneuropathy that unexpectedly proved to be caused by wild-type ...

Transthyretin Stabilizers and Seeding Inhibitors as Therapies for Amyloid Transthyretin Cardiomyopathy

Pharmaceutics, 2023
Transthyretin (TTR) amyloid cardiomyopathy (ATTR-CM) is a progressive and increasingly recognized cause of heart failure which is associated with high mortality and morbidity. ATTR-CM is characterized by the misfolding of TTR monomers and their deposition within the myocardium as amyloid fibrils.

Nonviral Gold Nanoparticle‐Mediated Delivery of CRISPR‐Cas9 Ribonucleoprotein and Long DNA Transgenes Into Primary Blood Cells

Advanced NanoBiomed Research, EarlyView.
CRISPR/Cas9 has revolutionized the field of gene therapy, but delivery remains an outstanding issue. We propose a nonviral gold‐nanoparticle platform for co‐delivery of CRISPR/Cas9 ribonucleoprotein and long 2.1 kilobase dsDNA transgene constructs. This CRISPR‐AuNP is inexpensive to produce and mediate gene editing and DNA delivery in T cells and CD34+

Decoding RNA regulation: Challenges and opportunities for RNA‐based therapies in Europe

British Journal of Clinical Pharmacology, EarlyView.
Abstract RNA‐based medicinal products represent a promising frontier in personalised medicine, offering sequence‐specific disease targeting at various molecular levels, yet their clinical translation in the European Union (EU) may be hindered by regulatory uncertainty around definitions and evidence requirements; this study therefore aims to identify ...

Early Progression of Aortic Stenosis Associated With Iatrogenic Variant Transthyretin Amyloidosis After Domino Liver Transplantation

JACC: Case Reports, 2020
We report a 65-year-old man who underwent aortic valve replacement because of severe aortic stenosis associated with de novo iatrogenic variant transthyretin amyloidosis derived from a liver graft extracted from a patient with hereditary transthyretin ...

Fibroblasts endocytose and degrade transthyretin aggregates in transthyretin-related amyloidosis [PDF]

Laboratory Investigation, 2013
Transthyretin (TTR)-related amyloidosis is a fatal disorder characterized by systemic extracellular deposition of TTR amyloid fibrils. Mutations in the TTR gene cause an autosomal dominant form of the disease-familial amyloidotic polyneuropathy (FAP). Wild-type (WT) TTR can also form amyloid fibrils in elderly patients with senile systemic amyloidosis.

IMACulate(DE3), an E. coli Strain for High Purity His‐Tagged Protein Purifications

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Immobilised Metal Affinity Chromatography (IMAC) is widely used to purify his‐tagged recombinant proteins from Escherichia coli. However, endogenous contaminants with histidine clusters, such as GFAT and PDH E1 proteins, are often co‐purified with the target protein.

Case Report: Transthyretin Glu54Leu—a rare mutation with predominant cardiac phenotype

Frontiers in Cardiovascular Medicine, 2023
We report two unrelated Bulgarian families with hereditary transthyretin (ATTR) amyloidosis due to a rare p.Glu74Leu (Glu54Leu) pathogenic variant found in seven individuals—three of them symptomatic.

Cerebrovascular Events in Aortic Stenosis: From Native Valve Disease to TAVR‐Specific Risk and Prevention

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Aortic stenosis (AS) is associated with a heightened burden of cardiovascular comorbidities, atrial fibrillation (AF), and progressive valvular calcification, all of which may contribute to cerebrovascular events across the disease continuum.
