Differential response of normal and tumor cells to nucleosome depletion

ABSTRACT: Gene-expression in siRNA treated U2OS and hTERT-RPE1 cells showed that CASP8AP2, NPAT and HINFP do not regulate expression of each other, and do not have any common target genes, except histones. Most histone genes are downregulated in U2OS cells following loss of CASP8AP2, NPAT or HINFP. In normal cells, highly-expressed histone genes were downregulated, albeit less than in tumor cells following loss of CASP8AP2. The p53 target genes were upregulated relatively late, clearly after the changes in expression of histone genes were observed.

The p53 target genes were upregulated relatively late, clearly after the changes in expression of histone genes were observed. U2OS and hTERT-RPE1 cells were treated with CASP8AP2, NPAT, HINFP or control siRNA in duplicates or triplicates and collected for RNA purification on 1st, 2nd and 3d days.

Histone genes transcription regulators binding in human cancer (U2OS) and normal (hTERT-RPE1) cells

Project description:The regulation of replication-dependent histone genes by CASP8AP2 and NPAT is likely direct, based on ChIP-seq. CASP8AP2 and NPAT ChIP-Seq peaks were enriched near transcription start sites (TSSs) of replication-dependent, but not replication-independent histone genes on chromosomes 1, 6 and 12 in both cell lines. HINFP ChIP-Seq peaks were enriched near transcription start sites (TSSs) of replication-dependent histone genes H4 and H2B and replication-independent histone genes H1FX and H1F0 in both cell lines. Another histone gene regulator, E2F1 also bound to TSSs of many histone genes mainly replication-independent.

Long-range genomic contacts and spatiotemporal chromatin landscape of human histone gene clusters at Histone Locus Bodies during the cell cycle in breast cancer [cHiC]

Project description:Cell cycle controlled mechanistic remodeling of chromatin architecture at HLBs as non-membranous phase-separated nuclear domains represents a novel dimension to regulation of cell proliferation. Therefore, we sought to resolve a gap in our understanding of how 3D higher-order genomic organization supports the activation of multiple clustered histone genes. Our findings are consistent model that the HINFP/NPAT complex controls the formation and dynamic remodeling of higher-order genomic organization of histone gene clusters at HLBs in early to late G1 phase to support production of histone mRNAs in S phase. that the two principal histone gene regulators HINFP and NPAT are located at anchor-points for chromatin loops reflecting their obligatory functions in remodeling the spatiotemporal genomic organization at HLBs during the G1 phase to accommodate histone gene expression in S phase.

hTERT promotes cell adhesion and migration independent of telomerase activity

Project description:We sequenced mRNA from 6 human cell lines stably over-expressed specific gene or empty vector, and searched for differently expressed genes after gene over-expression as compared to empty vector. mRNA levels were compared as following pairs: U2OS+hTERT vs U2OS+vector; U2OS+hTERTmut vs U2OS+vector; VA-13+hTERT vs VA-13+vector; VA-13+hTERTmut vs VA-13+vector.
