RNA sequencing in untreated (UN), sodium arsenite (SA) and heat shock (HS) stressed HeLa,HUVEC and THP-1 cells

Mammalian cells activate diverse defense mechanisms in response to stresses. Nuclear stress bodies (nSBs) are transient membraneless organelles in primates that only form upon severe stresses. Little is known on how their formation contributes to cellular homeostasis or whether nSBs have any pathophysiological roles. We observed that the de novo formation of nSBs accompanies enlarged pericentromeric SatⅢ DNA chromatin loci, prompting us to investigate whether such an acute alteration impacts regional chromatin accessibility and gene expression.
