Rb-mediated heterochromatin formation and silencing of E2F target genes during cellular senescence.

TL;DR: A distinct heterochromatic structure that accumulates in senescent human fibroblasts is described, which is designated senescence-associated heterochROMatic foci (SAHF) and is associated with the stable repression of E2F target genes.
Journal ArticleDOI

Senescence of activated stellate cells limits liver fibrosis

TL;DR: In this paper, the authors show that senescent cells accumulate in murine livers treated to produce fibrosis, a precursor pathology to cirrhosis, derived primarily from activated hepatic stellate cells, which initially proliferate in response to liver damage and produce the extracellular matrix.
Journal Article

Senescence of Activated Stellate Cells Limits Liver Fibrosis

TL;DR: It is shown that senescent cells accumulate in murine livers treated to produce fibrosis, a precursor pathology to cirrhosis, and natural killer cells preferentially kill senescent activated stellate cells in vitro and in vivo, thereby facilitating the resolution of fibrosis.
Journal ArticleDOI

Regulating Gene Expression through RNA Nuclear Retention

TL;DR: A role of the cell nucleus in harboring RNA molecules that are not immediately needed to produce proteins but whose cytoplasmic presence is rapidly required upon physiologic stress is revealed.
