Abstract
The characteristic events in neurodegenerative diseases (NDDs) encompass protein misfolding, aggregation, accumulation, and their related cellular dysfunction, synaptic function loss. While distinct proteins are implicated in the pathological processes of different NDDs, the process of protein misfolding and aggregation remains notably similar across various conditions. Specifically, proteins undergo misfolding into beta-folded (β-folded) conformation, resulting in the formation of insoluble amyloid proteins. Despite advancements in comprehending protein aggregation, certain facets of this intricate process remain incompletely elucidated. In recent years, the concept that long non-coding RNAs (lncRNAs) contribute to protein aggregation has gained recognition. LncRNAs influence the formation of protein aggregates by facilitating protein overexpression through the regulation of gene transcription and translation, inhibiting protein degradation via lysosomal and autophagic pathways, and targeting aberrant modifications and phase transitions of proteins. A better understanding of the relationship between lncRNAs and aberrant protein aggregation is an important step in dissecting the underlying molecular mechanisms and will contribute to the discovery of new therapeutic targets and strategies.
Highlights
NDDs are marked by protein misfolding, aggregation, and accumulation, leading to cellular dysfunction and loss of synaptic function.
Despite different proteins being involved in various NDDs, the process of misfolding into β-folded conformations and forming insoluble amyloid proteins is consistent across conditions.
The role of lncRNAs in protein aggregation has gained attention, as they regulate gene transcription and translation, inhibit protein degradation, and target aberrant protein modifications.
Understanding the link between lncRNAs and protein aggregation is crucial for uncovering molecular mechanisms and developing new therapeutic targets.
