CVD increases with age, 11 as does mitochondrial dysfunction. 12 Many lines of evidence from animal models and human studies implicate mitochondrial DNA (mtDNA) heteroplasmy 13 and mitochondrial ...

This study reveals how SV40 helicase unwinds DNA, highlighting ATP hydrolysis's role in translocation and offering insights ...

Using SPARXS, scientists gain new insights into how the structure and function of DNA depend on sequence. It can also quickly find the best sequence for applications ranging from nanotechnology to ...

BACKGROUND: Heart failure (HF) is a leading cause of morbidity and mortality worldwide. RNA-binding proteins are identified as regulators of cardiac disease; DDX5 (dead-box helicase 5) is a master ...

The receptor tyrosine kinase ROR2 mediates noncanonical WNT5A signaling to orchestrate tissue morphogenetic processes, and dysfunction of the pathway causes Robinow syndrome, brachydactyly B, and ...

The process starts when a signal, also called an action potential, is sent from the neuron's cell body towards the axon. Along the surface of the axon membrane are channels that allow ions like sodium ...

The thyroid cartilage is a cartilage structure that sits above the thyroid gland in front of the larynx. Learn more about its structure and function.

CMG (Cdc45‐MCM‐GINS) helicase assembly at the replication origin is the culmination of eukaryotic DNA replication initiation. This process can be reconstructed in vitro using defined factors in ...
