Project description:Amorphous silica nanoparticles induce malignant transformation and tumorigenesis of human lung epithelial cells. We used microarrays to detail the global programme of gene expression underlying the cellular malignant transformation induced by amorphous silica nanoparticles and identified distinct classes of up-regulated and down-regulated genes during this process.

Project description:Amorphous silica nanoparticles induce malignant transformation and tumorigenesis of human lung epithelial cells. We used microarrays to detail the global programme of gene expression underlying the cellular malignant transformation induced by amorphous silica nanoparticles and identified distinct classes of up-regulated and down-regulated genes during this process. The human lung epithelial cells, Beas-2B were continuously exposed to 5 μg/mL amorphous silica nanoparticles for 40 passages, and named as BeasSiNPs-P40 (shortly as P40-5 during the further microarray detection). Meanwhile, the passage-matched control Beas-2B cells, named as Beas-P40 (shortly as NC during the further microarray detection).

Project description:Titanium is a common implant material. However, in some patients titanium implants fail. Macrophages are key cells involved in foreign body response. To identify macrophage response to titainum, primary human macrophages were cultured on porous titanium discs for 6 days We used microarrays to determine the global expression pattern induced by porous titanium in macrophages and identify potential genes involved in implant failure.

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to amorphous Silica nanoparticles on Human hepatoma (HepG2) cells. We performed whole genome DNA microarray experiments using HepG2 cells exposed to for 24h. We used whole genome microarrays to screen for global changed in HepG2 transcription profiles and with subsequent quantitative analysis conducted on selected genes.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.

Project description:In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to amorphous Silica nanoparticles on Human hepatoma (HepG2) cells. We performed whole genome DNA microarray experiments using HepG2 cells exposed to for 24h. We used whole genome microarrays to screen for global changed in HepG2 transcription profiles and with subsequent quantitative analysis conducted on selected genes. 24h SiO2-NP (100 mg/L) exposed HepG2 cells were used for total RNA extraction and hybridization on Affymetrix microarrays.

Project description:Little is known about the global gene expression profile of macrophages in response to changes in size and porosity of silica nanoparticles (SNPs). Spherical nonporous SNPs of two different diameters, and mesoporous spherical SNPs with comparable size were characterized. Reactive oxygen species, mitochondrial membrane potential, lysosome degradation capacity, and lysosome pH were measured to evaluate the influence of nonporous and mesoporous SNPs on mitochondrial and lysosomal function. RNA-sequencing was utilized to generate transcriptional profiles of RAW264.7 macrophages exposed to non-toxic SNP doses. DESeq2, limma, and BinReg2 software were used to analyze the data based on both unsupervised and supervised strategies to identify genes with greatest differences among NP treatments. Utilizing GATHER and DAVID software, possible induced pathways were studied. We found that mesoporous silica nanoparticles are capable of altering gene expression in macrophages at doses that do not elicit acute cytotoxicity, while gene transcription was minimally affected by nonporous SNPs.

Project description:BACKGROUND: Long terminal repeat (LTR) retrotransposons make up a large fraction of the typical mammalian genome. They comprise about 8% of the human genome and approximately 10% of the mouse genome. On account of their abundance, LTR retrotransposons are believed to hold major significance for genome structure and function. Recent advances in genome sequencing of a variety of model organisms has provided an unprecedented opportunity to evaluate better the diversity of LTR retrotransposons resident in eukaryotic genomes. RESULTS: Using a new data-mining program, LTR_STRUC, in conjunction with conventional techniques, we have mined the GenBank mouse (Mus musculus) database and the more complete Ensembl mouse dataset for LTR retrotransposons. We report here that the M. musculus genome contains at least 21 separate families of LTR retrotransposons; 13 of these families are described here for the first time. CONCLUSIONS: All families of mouse LTR retrotransposons are members of the gypsy-like superfamily of retroviral-like elements. Several different families of unrelated non-autonomous elements were identified, suggesting that the evolution of non-autonomy may be a common event. High sequence similarity between several LTR retrotransposons identified in this study and those found in distantly-related species suggests that horizontal transfer has been a significant factor in the evolution of mouse LTR retrotransposons.
