“…One common population variant (R280H) had no pronounced effect on the interactions with POLβ, PARP-1, LIG3α and PCNA, but did reduce DNA-binding ability. When expressed in HeLa cells, the XRCC1 variants—excluding E98K, which was largely nucleolar, and C389Y, which exhibited reduced expression—exhibited normal nuclear distribution. …”

“…Here we have used siRNAs and time-lapse epifluorescence microscopy to examine the roles of various candidate mitotic cyclins in chromatin condensation in HeLa cells. Knocking down cyclin A2 resulted in a substantial (∼7 h) delay in chromatin condensation and histone H3 phosphorylation, and expressing an siRNA-resistant form of cyclin A2 partially rescued chromatin condensation. …”

“…Moreover, in presence of FAs, the E(2)-induced recruitment of the EAB1 co-activator peptide to ERα is masked and the E(2)-induced estrogen response element (ERE)-mediated transactivation is inhibited. In HeLa cells, in absence of E(2), FAs inhibited the ERE-mediated transactivation by ERβ but not ERα, while in presence of E(2), FAs inhibited ERE-activity by both ERβ and ERα. …”

“…Accordingly, the HEAT repeat clusters in two non-SMC Condensin II subunits, N-CAPD3 and N-CAPG2, are capable of recognizing H4K20me(1), and ChIP-seq. analysis demonstrate a significant overlap of Condensin II and H4K20me(1) sites in mitotic HeLa cells. Thus, the identification and characterization of the first H4K20me(1) demethylase, PHF8, has revealed an intimate link between this enzyme and two distinct events in cell cycle progression.…”

Our data indicate that Letm1 and UCP2/3 independently contribute to two distinct, mitochondrial Ca(2+) uptake pathways in intact endothelial cells.…”
