HDGFR2 regulates osteogenic differentiation by balancing histone crotonoylation and acetylation modifications [RNA-Seq]

Project description:Epigenetics regulates the expression of osteogenic genes and mediates the osteogenic differentiation of MSCs. It was found that hepatoma-derived growth factor (HDGFR2) is a histone methylated reader protein, which can recognize histone methylation modification and play an important "switch" role in gene transcriptional regulation. It is unclear whether HDGFR2 is involved in bone formation studies. Our study aims to investigate the effect of HDGFR2 on osteogenic differentiation and provide evidence for BMSCs as seed cells for tissue regeneration. We found that compared with the wild-type (WT) mice, the bone mass of the femur and the root furcation bone in HDGFR2-KO mice was significantly elevated to attenuate age-related bone loss. Compared with the BMSCs in WT mice, the cloning and osteogenic differentiation of BMSCs in HDGFR2-KO mice were significantly accelerated, and vice versa when HDGFR2 was overexpressed. GO analysis suggested that differential genes were mainly involved in osteoblast differentiation, ossification, collagen fiber tissue and mineralization. The bone defect repair ability of HDGFR2-KO mice was significantly enhanced compared to the control group. Moreover, the depletion of HDGFR2 suppressed periodontal bone loss. The HDGFR2 interacts with the active regulator of SIRT1 (AROS) and sirtuin family deacetylases to form a chromatin remodeling complex, and AROS regulated osteogenesis through combining with HDFGR2. The decreased ratio of H3K18 crotonylation to acetylation improved the transcription of osteogenic genes in HDGFR2 knockout BMSCs. Taken together, these data demonstrated that the knockdown of HDGFR2 could promote osteogenic differentiation and bone repair, providing a new theoretical basis for bone tissue regeneration.

Fast single-cell joint analysis of histone modifications and transcriptome by Droplet Paired-Tag

Project description:Analysis of histone modifications at single-cell resolution can provide insights into the cellular heterogeneity in activity states of regulatory elements. However, current methods are hindered by lengthy procedures and insufficient sensitivity. Here we present Droplet Paired-Tag, a microfluidic cell barcoding-based method for fast and robust joint analysis of histone modifications and gene expression from single cells. We applied Droplet Paired-Tag to mouse brain and demonstrated its utility in accurately identifying active or repressive regulatory elements, and resolving the dynamic interactions between candidate regulatory elements and putative target genes.

CUT&Tag recovers up to half of ENCODE ChIP-seq histone acetylation peaks

Project description:We comprehensively benchmarked CUT&Tag for H3K27ac and H3K27me3 against published ChIP-seq profiles from ENCODE in K562 cells. Combining multiple new and published CUT&Tag datasets, there was an average recall of 54% known ENCODE peaks for both histone modifications. To optimize data analysis steps, we tested peak callers MACS2 and SEACR and identified optimal peak calling parameters. Considering both precision and recall of known ENCODE peaks, the peak callers were comparable in their performance, although peaks produced by MACS2 match ENCODE peak width distributions more closely. We found that reducing PCR cycles during library preparation lowered duplication rates at the expense of ENCODE peak recovery. Despite the moderate ENCODE peak recovery, peaks identified by CUT&Tag represent the strongest ENCODE peaks and show the same functional and biological enrichments as ChIP-seq peaks identified by ENCODE. Our workflow systematically evaluates the merits of methodological adjustments, providing a benchmarking framework for the experimental design and analysis of CUT&Tag studies, and will facilitate future efforts to apply CUT&Tag in human tissues and single cells.

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.
