Description
Alu elements are major contributors to lineage-specific new exons in primate and human genomes. Recent studies indicate that some Alu exons have high transcript inclusion levels or tissue-specific splicing profiles, and may play important regulatory roles in modulating mRNA degradation or translational efficiency. However, the contribution of Alu exons to the human proteome remains unclear and controversial. The prevailing view is that exons derived from young repetitive elements, such as Alu elements, are restricted to regulatory functions and have not had adequate evolutionary time to be incorporated into stable, functional proteins. We adopt a proteotranscriptomics approach to systematically assess the contribution of Alu exons to the human proteome. Using RNA sequencing, ribosome profiling and proteomics data from human tissues and cell lines, we provide evidence for the translational activities of Alu exons and the presence of Alu exon derived peptides in human proteins. These Alu exon peptides represent species-specific protein differences between primates and other mammals, and in certain instances between humans and closely related primates. In the case of the RNA editing enzyme ADARB1, which contains an Alu exon peptide in its catalytic domain, RNA sequencing analyses of A-to-I editing demonstrate that both the Alu exon skipping and inclusion isoforms encode active enzymes. The Alu exon derived peptide may fine tune the overall editing activity and, in limited cases, the site selectivity of ADARB1 protein products. Our data indicate that Alu elements have contributed to the acquisition of novel protein sequences during primate and human evolution. Overall design: Comparing the A-I RNA editing levels of HEK293 cells transfected with empty vector (CV) control, Alu exon inclusion (long) isoform of ADARB1, and Alu exon skipping (short) isoform of ADARB1. Each group has 3 replicates.

Description
Glyphosate (GLY) is an effective antimetabolite that acts against the shikimate pathway 5-enolpyruvylshikimate 3-phosphate (EPSP) synthase, However, little is known about the genome-scale transcriptional responses of bacteria after glyphosate shock. To investigate further the mechanisms by which E. coli response to a glyphosate shock, a DNA-based microarray was used for transcriptional analysis of E. coli exposed to 200 mM glyphosate.

Description
Induced pluripotent stem cells (iPSCs) can be derived from somatic cells through ectopic expression of transcriptional factors or chemical cocktails. Chemical reprogramming might be safe than transcriptional factors since there is no integration of exogenous genes. However, there is still little direct evidence to prove this hypothesis. In this study, we have performed whole genome profiling of the DNA methylomes of mouse chemical iPSCs (CiPSCs), transcriptional factors induced iPSCs (TF-iPSCs) and embryonic stem cells (ESCs). We find that the methylation levels of high-CpG-density promoters (HCPs) and intermediate- CpG-density promoters (ICPs) have no significant difference among them, but low-CpG-density promoters (LCP) and three retrotransposons (LINEs, LTRs and SINEs) show preference to different methylation levels. Surprisingly, CiPSCs are hypomethylated than TF-iPSCs and the major difference of methylation levels lies in the intergenic regions while two iPSCs lines are generally hypermethylated compared to ESCs. Moveover, we find the methylation states of imprinting control regions (ICRs) and the expression of imprinted genes of CiPSCs are more resemble ESCs than TF-iPSCs. Our data first provide the epigenetic states of chemical induced pluripotent stem cells and compare the difference of mouse CiPSCs, TF-iPSCs and ESCs. These observations might affect ongoing choices of reprogramming methods for disease modeling and give some guides for potential therapeutic applications. Overall design: Comparison of DNA methylation and genes expression patterns in 3 cell types
