The distribution of HP1α in the genome of intrahepatic cholangiocarcinoma cells

Project description:Heterochromatin Protein 1α (HP1α, encoded by the CBX5 gene) is one of the most important HP1 family members and is a nonhistone chromosomal proteins involved in transcriptional silencing via heterochromatin formation and structural maintenance. Many studies have shown that the distribution of HP1α on polytene chromosomes is not restricted to the chromocenters or telomeres. HP1α binds to chromatin mainly through direct interactions with modified histones, especially trimethylated H3K9 (H3K9me3), through the Chromo domain, and by interactions with other proteins through the Chromo shadow domain. In cancerous lesions, HP1α is involved in the regulation of malignant behaviors, such as cell proliferation and cell cycle progression. To study the distribution of HP1α in the genome of intrahepatic cholangiocarcinoma cells, CUT & Tag was performed. We found that HP1α was significantly distributed in the promoter region of proliferation-related encoding genes. No peaks were detected in the normal control sample.

The profiling of methylation and acetylation modification of histone H3 in Intrahepatic cholangiocarcinoma cells

Project description:Abnormal distribution of histone modifications has been confirmed to influence the development and progression of neoplastic diseases. Methylation modifications of histone H3 include H3K9me3, H3K27me3 and H3K4me3. Acetylation modifications of histone H3 include H3K9ac and H3K27ac. Among these modifications in the promoter region, H3K9me3 and H3K27me3 serve as inhibiting factors for transcription, while H3K4me3, H3K9ac and H3K27ac are important promoting factors for transcription. To make sure the distribution of these histone modifications in intrahepatic cholangiocarcinoma (ICCA) cells, CUT & Tag was performed. We found that these modifications were located in the promoter or non-promoter regions (e.g., intergenic, exon and intron regions) of key tumor-associated genes, indicating the potential role of chromatin remodeling complexes in ICCA diagnosis and treatment.
