Epigenetics—Innovations and Misconceptions

Natural Sciences, Volume 6, Issue 2, April 2026.
ABSTRACT Epigenetics is a scientific field whose definition has changed over time. Established in the 1940s by C.H. Waddington by synthesis from embryology and genetics, the term “epigenetics” is now mainly used to describe the role of chromatin modifications in the regulation and perpetuation of gene activity states.

Functions of J‐domain proteins in mitochondrial protein biogenesis

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Mitochondrial biogenesis and functions depend on the import and assembly of more than 1000 proteins that are made as precursors on cytosolic ribosomes. The majority of these precursor proteins are transported from the ribosome to the translocase of the outer membrane (TOM complex), which constitutes the main entry site for mitochondrial ...

Toxic mechanisms of amyloid oligomers and therapeutic strategies

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Amyloid oligomers are increasingly recognized as the major toxic contributors across protein‐misfolding disorders. In this review, we cover mechanistic evidence showing how these transient and structurally heterogeneous oligomers disrupt cellular homeostasis by: (i) permeabilizing lipid membranes and forming ion‐conducting pores; (ii ...

In vitro, cellular and in vivo studies of amyloid oligomers structure and toxicity: Challenges and advances

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Oligomeric assemblies of amyloidogenic proteins, such as Aβ, tau, α‐synuclein, amylin, transthyretin, and TDP‐43, are increasingly recognized as key drivers of cellular dysfunction across a range of neurodegenerative and systemic disorders.
