Affymetrix Yeast Genome S98 Array (ygs98)
Description
The conserved multi-subunit Ccr4-Not complex regulates gene expression in diverse ways. In this work, we characterize the suppression of temperature sensitivity associated with a mutation in the gene encoding the scaffold subunit of the Ccr4-Not complex, NOT1, by the deletion of SPT3.
Publication Title
A SAGA-independent function of SPT3 mediates transcriptional deregulation in a mutant of the Ccr4-not complex in Saccharomyces cerevisiae.

Description
Positive selection occurs in the thymic cortex, but critical maturation events occur later in the medulla. We defined the precise stage at which T cells acquire competence to proliferate and emigrate. Transcriptome analysis of late gene changes suggested roles for NF-B and interferon signaling. Mice lacking the IKK kinase TAK1, showed normal positive selection, but a specific block in functional maturation. NF-B signaling provided protection from TNF, and was required for proliferation and emigration. Alternatively, the interferon signature was independent of NF-B, and IFNR deficient thymocytes showed reduced STAT1 levels and phenotypic abnormality, but were competent to proliferate. Thus, both NF-B and tonic IFN signals are involved in the final maturation of thymocytes into nave T cells.
Publication Title
Late stages of T cell maturation in the thymus involve NF-κB and tonic type I interferon signaling.

Description
The function and retention/reprogramming of epigenetic marks during the germline-to-embryo transition is a key issue in developmental and cellular biology, with relevance to stem cell programming and trans-generational inheritance. In zebrafish, DNAme patterns are programmed in transcriptionally-quiescent early cleavage embryos; paternally-inherited patterns are maintained, whereas maternal patterns are reprogrammed to match the paternal pattern. Here we show that a 'placeholder' nucleosome, containing the histone H2A variant H2A.Z(FV) and H3K4me1, occupies virtually all regions lacking DNAme in both sperm and cleavage embryos – residing at promoters encoding housekeeping and early embryonic transcription factors. Upon genome-wide transcriptional onset, genes with the Placeholder become either active H3K4me3-marked or silent H3K4me3/K27me3-marked (bivalent). Importantly, functional perturbation causing Placeholder loss confers DNAme acquisition, whereas acquisition/expansion of Placeholder confers DNA hypomethylation and improper gene activation. Thus, during transcriptionally quiescent stages (gamete-zygote-cleavage), an H2A.Z(FV)/H3K4me1-containing Placeholder nucleosome deters DNAme, poising parental genes for either gene-specific activation or facultative repression. Overall design: Transcript abundance was analyzed for zebrafish sperm, and cleavage stage embryos that were either wild type or mutant for the anp32e gene.

Description
Epithelial cells provide an initial line of defense against damage and pathogens in barrier tissues such as the skin; however this balance is disrupted in obesity and metabolic disease. Skin gamma delta T cells recognize epithelial damage and release cytokines and growth factors that facilitate wound repair. To determine the impact of obesity and metabolic disease on skin gamma delta T cells, we isolated skin gamma delta T cells from 10-week old C57BLKS/J lean db/+ and obese db/db animals for further study. Due to a deficiency in the leptin receptor (db), homozygous db/db animals do not process satiety signals, continually eat and develop severe obesity and metabolic disease. Skin gamma delta T cells isolated from these animals were compared for changes in mRNA expression using microarray. We have determined that obesity and metabolic disease negatively impacts homeostasis and functionality of skin gamma delta T cells, rendering host defense mechanisms vulnerable to injury and infection.
Publication Title
Gammadelta T cells are reduced and rendered unresponsive by hyperglycemia and chronic TNFalpha in mouse models of obesity and metabolic disease.

Description
Primary micromass cultures derived from 11.5 day old mouse embryo limb buds were cultured for 15 days in differentiating conditions (beta-glycerophosphate and ascorbic acid). Total RNA from differentiating chondrocytes was isolated every three days i.e. days 3,6,9,12 and 15 and hybridized to MOE430A chips. Objective: Gain a view of the temporal gene expression changes occuring during chondrocyte differentiation.
