#heterochromatin — Public Fediverse posts

Why do #StemCells have lower levels of facultative #heterochromatin, defined by H3K27me3, compared to differentiated cells? By artificially lengthening G1 phase, @4everbiochemist &co show that G1 length is an essential determinant of H3K27me3 landscape @PLOSBiology https://plos.io/4lKfztO

CFDP1 regulates cell proliferation & higher-order #chromatin structure. This study shows that CFDP1 is essential for structural stability of centromeric #heterochromatin, so influencing #microtubule nucleation during #MitoticSpindle formation #PLOSBiology https://plos.io/3W5eFhc

Surprises from #FLIM-#FRET studies of nanometer-range distances between #nucleosomes in living, non-fixed cells:

Claire Dupont, Robert Feil, David Lleres et al show that constitutive #heterochromatin is in fact less compacted than bulk #chromatin
