AlphaFold and protein structure prediction in aging research
The CRISPR/Cas9 method facilitates targeted disruption of gene sequences, providing a reliable means to analyze gene-dependent regulatory pathways. This study aims to investigate melanogenesis in p21-knockout B16F1 cells generated by the CRISPR/Cas9 system. The mutation …
Researchers used computer simulations to map how a NAD+ analog activates SIR2, an enzyme linked to aging, by triggering a cascade of conformational changes that act like an internal relay system. They identified a previously …
Researchers discovered that naked mole rats—which live 10x longer than similar-sized rodents—have undergone massive evolutionary changes in protein structure, particularly in regions that handle stress and prevent cancer. These changes appear to stabilize certain proteins …
The clinical utility of nanobodies in solid tumor therapy is constrained by a fundamental biophysical trade-off: rapid renal clearance necessitates half-life extension, which in turn demands ultrahigh affinity to prevent dissociation from the target under …
Proteostasis and the gut microbiota are two major determinants of host health and longevity. Proteostasis ensures proper protein folding and degradation thereby preventing the accumulation of unwanted proteins. Similarly, microbiota contribute to host metabolism, immunity, …
Telomeres are protective DNA-protein structures at chromosome ends that play a crucial role in maintaining genome stability and regulating cellular aging. Their progressive shortening during cell division is counteracted by telomerase, a ribonucleoprotein enzyme composed …
Researchers used advanced imaging and mass spectrometry to map how insulin receptors behave in muscle cells, discovering they travel via two different cellular pathways—one involving caveolin and one involving clathrin. This fundamental understanding of insulin …
