Description
Transciptomic analysis of germline tumor cells to understand the role of autophagy and neuronal differentiation in lifespan extension. Overall design: Methods: Worms were grown on control L444 seeded plates or gld-1 RNAi seeded plates and subjected to RNA isolation and sequencing using standard Illumina protocols. Conclusions: Fasting of animals expressing tumors increases their lifespan two-fold through autophagy and modular changes in transcription as well as metabolism.

Affymetrix Yeast Genome 2.0 Array (yeast2)
Description
We undertook an inter-laboratory effort to generate high-quality quantitative data for a very large number of cellular components in yeast using transcriptome and metabolome analysis. We ensured the high-quality of the experimental data by evaluating a wide range of sampling and measurement techniques. The data were generated for two different yeast strains, each growing under two different growth conditions and based on integrated analysis of the high-throughput data we hypothesize that differences in growth rates and yields on glucose between the two strains are due to differences in protein metabolism.

Description
We examined the effects of TNFa and Spt5, the major DSIF subunit, on nascent and mature transcripts using RNA-Seq of chromatin-associated and cytoplasmic transcripts. Overall design: RNA was extracted from the cytosolic and chromatin fractions of control and Spt5 KD cells that were treated with TNFa for 1 hour

Description
Autophagy is a membrane-trafficking process that directs degradation of cytoplasmic material in lysosomes. The process promotes cellular fidelity, and while the core machinery of autophagy is known, the mechanisms that promote and sustain autophagy are less well defined. Here we report that the epigenetic reader BRD4 and the methyltransferase G9a repress a TFEB/TFE3/MITF-independent transcriptional program that promotes autophagy and lysosome biogenesis. We show that BRD4 knockdown induces autophagy in vitro and in vivo in response to some, but not all, situations. In the case of starvation, a signaling cascade involving AMPK and histone deacetylase SIRT1 displaces chromatin-bound BRD4, instigating autophagy gene activation and cell survival. Importantly, this program is directed independently and also reciprocally to the growth-promoting properties of BRD4 and is potently repressed by BRD4-NUT, a driver of NUT midline carcinoma. These findings therefore identify a distinct and selective mechanism of autophagy regulation. Overall design: RNA-Seq of KP-4 pancreatic adenocarcinoma cells transfected with control, BRD4 #1 or BRD4 #2 siRNA for 72hrs (n=3 independent sample preparations)

Description
HEK293T cells were transfected with the Rbp1-amr or slow (R729H-amr) -amanitin resistant subunit of RNA Pol II and selected with -amanitin 24 hours after transfection for additional 24 hours. Total RNA was extracted and global changes in gene expression were determined using microarray chips.

Description
Thymic Treg cells, mature non-Treg CD4+ single positive thymocytes, peripheral (spleen) resting and activated Treg cells were sorted from Foxp3-gfp reporter (wid type, WT) mice or Foxp3 enhancer CNS3 knockout (KO, carrying the same GFP reporter) mice. Total RNA was extracted and used for RNA sequencing to assess gene expression profiles. Overall design: Two 6-8 week old littermates of male Foxp3-gfp and Foxp3?CNS3-gfp mice were used to sort Treg cells and conventional CD4+ T cells. Lymphocyte preparation and electronic sorting were performed at the same time. RNA extraction, SMART amplification, library preparation were conducted in parallel.

Description
To gain more insight into initiation and regulation of T cell receptor (TCR) gene rearrangement during human T cell development, we analyzed TCR gene rearrangements by quantitative PCR analysis in nine consecutive T-cell developmental stages, including CD34+ lin- cord blood cells as a reference. The same stages were used for gene expression profiling using DNA microarrays.
