Description
Technical advances have enabled the collection of genome and transcriptome data sets with single-cell resolution. However, single-cell characterization of the epigenome has remained challenging. Furthermore, because cells must be physically separated prior to biochemical processing, conventional single-cell preparatory methods scale linearly. We applied combinatorial cellular indexing to measure chromatin accessibility in thousands of single cells per assay, circumventing the need for compartmentalization of individual cells. We report chromatin accessibility profiles from over 15,000 single cells and use these data to cluster cells on the basis of chromatin accessibility landscapes. We identify modules of coordinately regulated chromatin accessibility at the level of single cells both between and within cell types, with a scalable method that may accelerate progress toward a human cell atlas. Overall design: 3 replicates from GM12878 and HL-60 cell lines collected for differential gene expression analysis.

Description
Here we describe sci-CAR, a combinatorial indexing strategy to jointly profile chromatin accessibility and mRNA in each of thousands of single cells. As a proof-of-concept, we apply sci-CAR to 4,825 cells comprising a time-series of dexamethasone treatment, as well as to 11,233 cells from the mouse kidney. Overall design: single cell RNA-seq and ATAC-seq co-profiling for HEK293T cells, NIH/3T3 cells, A549 cells across three treatment conditions (DEX 0 hour, 1 hour and 3 hour treatment), and wild type mouse kidney.

Description
The PI3K/Akt signaling pathway impacts various aspects of CD8 T cell homeostasis, such as effect versus memory cell differentiation, during viral infection. We used microarrays to determine which downstream molecules were affected and what other signaling pathways were interconnected with the Akt pathway by constitutive activation of Akt in LCMV-infected CD8 T cells.

Description
The insulin-like growth factor-I (IGF-IR) and androgen (AR) receptors are important players in prostate cancer biology. Functional interactions between the IGF-I and androgen signaling pathways seem to have crucial roles in the progression of prostate cancer from early (benign) to advanced (metastatic) stages. DNA methylation is a major epigenetic alteration affecting gene expression. Hypermethylation of tumor suppressor promoters is a frequent event in human cancer, leading to inactivation and repression of specific genes. The aim of the present study was to identify the entire set of methylated genes (methylome) in a cellular model that replicates prostate cancer progression.

Global methylation analysis identifies PITX2 as an upstream regulator of the androgen receptor and IGF-I receptor genes in prostate cancer.

Description
Dermal fibroblasts (dFB) resist infection by locally differentiating into adipocytes and producing the antimicrobial peptide cathelicidin in response to S. aureus. We found that neonatal dFB were highly adipogenic whereas this adipogenic function was lost during adulthood. To better understand the molecular nature of the change in antimicrobial and adipogenic function of dFB, we profiled the transcriptomes of primary dFB isolated at different ages by RNA-seq. RNA-seq identified the pro-adipogenic to pro-fibrotic gene signature switch in dFB during aging, and identified TGF-beta as the top up-regulated pathway that was activated in 2M dFB compared to neonatal P1 dFB. Overall design: Examination of differentially expressed genes in cultured primary dermal fibroblasts/pre-adipocytes isolated from mouse skin with various ages.

Expression profiles of Drosophila melanogaster in response to ionizing radiation, formaldehyde, toluene, and 2,3,7,8-tetrachlorodibenzo-p-dioxin. Overall design: RNA-seq analysis on 25,415 transcripts to measure the change in gene expression in males and females separately. An analysis of the genes unique to each treatment yielded a list of genes as a gene expression signature. In the case of radiation exposure, both sexes exhibited a reproducible increase in their expression of the transcription factors sugarbabe and tramtrack.
