Genome-wide profiling of histone H1 variants and H3K9me3 in T47D-MTVL cells upon multiple H1 depletion

Project description:Human somatic cells may contain up to seven members of the histone H1 family contributing to chromatin compaction and regulation of nuclear processes, apparently with certain subtype specificities. In breast cancer cells, the combined depletion of H1.2 and H1.4 has a strong deleterious effect, deregulates many genes, promotes the appearance of accessibility sites genome-wide, and triggers an interferon response via activation of heterochromatic repeats. We have further analyzed the consequences of multiple H1 variants depletion by profiling the occupancy of five somatic histone H1 variants and H3K9me3 post-translational modification in T47D-MTVL cancer cells. Specifically, stable breast cancer-derived cell lines expressing an shRNA against multiple histone H1 isoforms in response to doxycycline (Dox) were grown for six days in the presence or absence of Dox. ChIP-Seq experiments were subsequently performed to analyze the genome-wide localization of histone H1 variants and H3K9me3.

Genome-wide profiling of histone H1 variants in T47D-MTVL cells

Project description:Human somatic cells may contain up to seven members of the histone H1 family contributing to chromatin compaction and regulation of nuclear processes, apparently with certain subtype specificities. Previous studies in T47D breast cancer cells determined that H1 variants are distributed in a variant-specific manner throughout the genome, although only H1.2 and H1X endogenous variants were mapped. Now, we performed ChIP-seq of five endogenous H1 variants (H1.0, H1.2, H1.4, H1.5, H1X) in T47D cells.

Mapping of somatic linker histone H1 variants in T47D-MTVL cells

Project description:At least six histone H1 variants exist in mammalian somatic cells that bind to the linker DNA and stabilize the nucleosome particle contributing to higher order chromatin compaction. In addition, H1 seems to be involved in the active regulation of gene expression. It is not well known whether the different variants have specific roles, are distributed differentially along the genome, or regulate specific promoters. By taking advantage of specific antibodies to H1 variants and HA-tagged recombinant H1 variants expressed in a breast cancer-derived cell line, we have investigated the distribution of the different somatic H1 variants (H1.2 to H1.5, H1.0 and H1X) in particular promoters and genome-wide.

Analysis of the DNA topology upon multiple histone H1 variants depletion by Hi-C experiments

Project description:The combined depletion of histones H1.2 and H1.4 in T47D-MTVL human breast cancer cells has a strong deleterious effect, deregulates gene expression, promotes the appearance of genome-wide accessibility sites, and triggers the interferon response. We have further analyzed the consequences of multiple H1 variants depletion at the topological level by performing Hi-C experiments on T47D-MTVL cancer cells expressing a Dox-inducible shRNA against multiple H1 variants.
