Modulation of Epigenetic Control by Advanced Molecular Tweezers

Chemistry – A European Journal, EarlyView.
Tailored dimeric molecular tweezers recognize the DNA‐binding part of Histone H4 and interrupt the essential histone‐DNA interaction. ABSTRACT This work addresses the question if supramolecular systems can be tailored to interfere with posttranslational modifications (PTM) and epigenetics.

Vibrational Optical Activity of Amyloid Fibrils

ChemPlusChem
Abstract Amyloid fibrils are supramolecular systems showing distinct chirality at different levels of their complex multilayered architectures. Due to the regular long‐range chiral organization, amyloid fibrils exhibit the most intense Vibrational Optical Activity (VOA) signal observed up to now, making VOA techniques: Vibrational ...

Structural polymorphism of α-synuclein fibrils alters the pathway of Hsc70-mediated disaggregation

The EMBO Journal
Pathological aggregation of α-synuclein into amyloid fibrils is a hallmark of synucleinopathies, including Parkinson’s disease. Despite this commonality, synucleinopathies display divergent disease phenotypes that have been attributed to disease-specific

Progression and prognostic significance of electrocardiographic findings in patients with cardiac amyloidosis

ESC Heart Failure, Volume 12, Issue 2, Page 809-818, April 2025.
Abstract Aims This study aimed to evaluate the change of the main electrocardiographic (ECG) characteristics and their prognostic role across the main subtypes of cardiac amyloidosis [light‐chain amyloidosis (AL) and hereditary (ATTRv) and wild‐type transthyretin amyloidosis (ATTRwt)].

Transthyretin amyloid cardiomyopathy: Literature review and red‐flag symptom clusters for each cardiology specialty

ESC Heart Failure, Volume 12, Issue 2, Page 955-967, April 2025.
Abstract Wild‐type transthyretin amyloid cardiomyopathy (ATTRwt‐CM) is a progressive and infiltrative cardiac disorder that may cause fatal consequences if left untreated. The estimated survival time from diagnosis is approximately 3–6 years. Because of the non‐specificity of initial symptom manifestation and insufficient awareness among treating ...

Correlation between Nanomechanics and Polymorphic Conformations in Amyloid Fibrils

, 2016
Amyloid fibrils occur in diverse morphologies, but how polymorphism affects the resulting mechanical properties is still not fully appreciated. Using formalisms from the theory of elasticity, we propose an original way of averaging the second area moment

Real‐world characteristics and treatment of cardiac transthyretin amyloidosis: A multicentre, observational study

ESC Heart Failure, Volume 12, Issue 2, Page 1203-1216, April 2025.
The 366 patients diagnosed with transthyretin amyloidosis cardiomyopathy (ATTR‐CM) were analyzed regarding their clinical characteristics in the first year after approval of tafamidis 61 mg for ATTR‐CM in Germany. Nearly two‐thirds of the patients were in an advanced disease stage and 64% met the key criteria of the “Transthyretin Amyloidosis ...
