View SamplesPeak bone mass (PBM) is an important determinant of osteoporosis. Circulating monocytes may serve as early progenitors of osteoclasts and produce important molecules for bone metabolism. To search for genes functionally important for osteoclastogenesis, we performed a whole genome gene differential expression study of circulating monocytes in human subjects with extremely low vs. high peak bone mass.

View SamplesIn this study, we analyzed transcriptome gene expression microarray, epigenomic miRNA microarray and methylome sequencing data simultaneously in PBMs from 5 high hip BMD subjects and 5 low hip BMD subjects. Through integrating the transcriptomic and epigenomic data, firstly we identified BMD-related genetic factors, including 9 protein coding genes and 2 miRNAs, of which 3 genes (FAM50A, ZNF473 and TMEM55B) and one miRNA (hsa-mir-4291) showed the consistent association evidence from both gene expression and methylation data, and 3 genes (TMEM55B, RNF40 and ALDOA) were confirmed in the meta-analysis of 7 GWAS samples and GEnetic Factors for OSteoporosis consortium (GEFOS-2) GWAS results. Secondly in network analysis we identified an interaction network module with 12 genes and 11 miRNAs including AKT1, STAT3, STAT5A, FLT3, hsa-mir-141 and hsa-mir-34a which have been associated with BMD in previous studies. This module revealed the crosstalk among miRNAs, mRNAs and DNA methylation and showed four potential regulatory patterns of gene expression to influence the BMD status, including regulation by gene methylation, by miRNA and its methylation, by transcription factors and co-regulation by miRNA and gene methylation. In conclusion, the integration of multiple layers of omics can yield more in-depth results than analysis of individual omics data respectively. Integrative analysis from transcriptomics and epigenomic data improves our ability to identify causal genetic factors, and more importantly uncover functional regulation pattern of multi-omics for osteoporosis etiology.

View SamplesThe recovery of liver mass is mainly mediated by proliferation and enlargement of hepatocytes after partial hepatectomy. Studying the gene expression profiles of hepatocytes after partial hepatectomy will be helpful in exploring the mechanism of liver regeneration.

View SamplesThe liver has extraordinary powers of regeneration after partial hepatectomy (PH). Changes of gene expression play a key role in cell proliferation and differentiation during liver regeneration (LR). To understand the molecular mechanisms underlying LR, this study was designed to assess the changes of rat hepatic gene expression in a timely manner.

View SamplesAllopolyploidy, entailing whole genome duplication (WGD) of merged divergent genomes of different species, often instigates transcriptome shock, whereby both total gene expression level and homeolog expression partitioning can be disrupted and remodeled. Little is known about the extent to which the parental expression-conserved genes will be disrupted/remodeled by allopolyploidization, nor the evolutionary relevancy of shock-induced expression repatterning. Here, by microarray-based gene expression profiling and gene-specific cDNA-pyrosequencing, we assessed transgenerational transcriptome shock in a synthetic allotetraploid wheat (AT2) with karyotype and basic morphology mimicking those of natural tetraploid wheat, Triticum turgidum. We show that the transcriptome shock in AT2 is exceptionally strong that it disrupted intrinsically conserved parental gene expression, and resulted in extensive expression nonadditivity in the newly formed allotetraploid plants. At total expression level, a substantial proportion of shock-induced novel expression, especially over-transgressive expression, was rapidly stabilized already in early generations of AT2. Extensive remodeling of homeolog expression occurred in AT2, including those genes that showed additive total expression, and which generated subgenome expression dominance, a pattern that mirrors T. turgidum. Thus, the shock-induced new patterns of gene expression at both the total expression level and subgenome homeolog partitioning showed evidence of evolutionary persistence. Complex relationships between homeolog expression remodeling and nonadditive total expression were observed in a tissue-specific manner.

View SamplesBackground: Signaling by receptor tyrosine kinases (RTK) is frequently dysregulated in gliomas. Inter-individual variability in the causes for dysregulated RTK signaling may have hampered the efficacy of targeted therapies. Using gene expression modules around key regulators in the RAS-RAF-MEK-MAPK cascade and in the phosphatidylinositol 3-kinase-AKT pathways, we developed a RMPA clustering scheme to distinguish gliomas with varying extents of RTK signaling.
