Description
Drought is an important environmental factor affecting plant growth and biomass production. Despite this importance little is known on the molecular mechanisms regulating plant growth under water limiting conditions. The main goal of this work was to investigate, using a combination of growth and molecular profiling techniques, how stress arrests CELl proliferation in Arabidopsis thaliana leaves upon osmotic stress imposition.

Description
We performed RNAseq with Saccharomyces cerevisiae cells under both transient and steady-state conditions to study the regulation of genes by two pulsatile transcription factors, Msn2 and Mig1. The transient data allowed us to identify combinatorial targets while the steady-state data was used to study target expression dependence on the relative pulse timing between the two TFs. Overall design: For transition experiments, 18 samples (3 different strains x 3 dfferent conditions x 2 biological replicates) were analyzed. For steady-state experiments, one strain was analyzed at 9 different glucose concentrations and the other strain was analyzed at one glucose condition.

Description
We develop a theoretical-computational framework for inferring cell state transition dynamics, and apply it to mouse embryonic stem cells states defined by expression levels of Esrrb, Tbx3, and Zscan4. RNA-seq was performed to characterize the larger transcriptional differences between states expressing combinations of these three specific genes, and proceed to explore their dynamic interconversion. Overall design: A double knock-in reporter for Esrrb and Tbx3 with distinct fluorescent proteins was constructed to enable purification of substates defined by their relative expression levels (Esrrb-/Tbx3-; Esrrb+/Tbx3-; Esrrb+/Tbx3+). A second line was constructed using a promoter-fragment reporter to isolate Zscan4+ from Zscan4- cells. Following FACS isolation, the subpopulations were sequenced on an Illumina HiSeq2500. Biological replicates were collected on different days.

Description
We report the application of single-cell and bulk RNA sequencing technology to examine the noncoding transcriptome of cells undergoing reprogramming to the pluripotent state. Overall design: Examination of noncoding RNAs in reprogrammming cells. We examined iPS cells grown in standard ES cell culture conditions, as well as iPS cells grown in "2i" conditions (small molecule inhibition of Mek and Gsk3). We also compared our iPS samples to male and female ES cells (mES, fES).

Description
During T cell development, multipotent progenitors relinquish competence for other fates and commit to the T cell lineage by turning on Bcl11b, which encodes a transcription factor. To clarify lineage commitment mechanisms, we followed developing T cells at the single-cell level using Bcl11b knock-in fluorescent reporter mice. Notch signaling and Notch activated transcription factors collaborate to activate Bcl11b expression irrespectively of Notch-dependent proliferation. These inputs work via three distinct, asynchronous mechanisms: an early locus ‘poising’ function dependent on TCF-1 and GATA-3, a stochastic-permissivity function dependent on Notch signaling, and a separate amplitude-control function dependent on Runx1, a factor already present in multipotent progenitors. Despite their necessity for Bcl11b activation, these inputs act in a stage specific manner, providing a multitiered mechanism for developmental gene regulation. Overall design: Two sets of samples were generated from DN T-cell sub-populations derived from culture of bone marrow progenitors from mice containing a knock-in Bcl11b-YFP reporter

Asynchronous combinatorial action of four regulatory factors activates Bcl11b for T cell commitment.

Description
Special AT-rich binding protein 1 (SATB1) is a global chromatin organizer and a transcription factor induced by interleukin-4 (IL-4) during the early T helper 2 (Th2) cell differentiation. In this study, we investigated the role of SATB1 in T helper cell differentiation by performing gene expression profiling of human differentiating Th cells in which expression of SATB1 was downregulated by RNA interference (RNAi). Our results indicate that SATB1 is involved in the regulation of more than three hundred genes in primary human CD4+ T cells, including several IL-12 and/or IL-4 regulated factors, suggesting a role in the development or function of Th subtypes.
Publication Title
SATB1 dictates expression of multiple genes including IL-5 involved in human T helper cell differentiation.
