TranscriptomicsWhiA and WhiB of Streptomyces venezuelae depend on each other for binding DNA
WhiB regulon, as determined by ChIP-Seq turned out to be identical to the WhiA regulon leading to the speculation that the two proteins might be required to work together to bind DNA. In this experiment WhiA ChIP-Seq was done in a whiB deletion background and, WhiB ChIP-Seq was done in a whiA deleti...

TranscriptomicsTranscription profiling of human primary human macrophages over the course of HIV-1 infection reveals HIV-1 activates macrophages independent of Toll-like receptors
Macrophages provide an interface between innate and adaptive immunity and are important long-lived reservoirs for Human Immunodeficiency Virus Type-1 (HIV-1). Multiple genetic networks involved in regulating signal transduction cascades and immune responses in macrophages are coordinately modulated ...

TranscriptomicsChIP-Seq to determine the binding sites of the transcription factor WhiB in the genome of Streptomyces venezuelae
WhiB is the founding member of a family of proteins (the WhiB-like [Wbl] family) that carry a [4Fe-4S] iron-sulfur cluster. It is essential for the process of developmentally controlled cell division leading to sporulation in Streptomyces species. This ChIP-Sea was carried out to determine unambiguo...

TranscriptomicsTranscriptional profiling of the developmental gene whiB deletion mutant of Streptomyces venezuelae ATCC 10712 at 7 time points from 8 to 20 hours of growth
WhiB is the founding member of a family of proteins (the WhiB-like [Wbl] family) that carry a [4Fe-4S] iron-sulfur cluster and play key roles in diverse aspects of the biology of actinomycetes, including pathogenesis, antibiotic resistance, and the control of development. In Streptomyces, WhiB is es...

TranscriptomicsMutation of the cysteine residues that coordinate the WhiB [4Fe-4S] cluster prevents in vivo DNA binding by both WhiB and WhiA
The purpose of this experiment was to show that the iron-sulphur cluster ([4Fe-4S]) of whiB is essential for the DNA binding by WhiB and WhiA. The \\"serine version of whiB\\" mentioned below is a whiB in which the 4 cysteine residues which coordinate the [4Fe-4S] cluster were mutated to serines. Ch...

TranscriptomicsTranscription profiling of mouse activin treated MEKK1 wild type and KO keratinocytes
MEKK1 wildtype and knockout keratinocytes were compared both with and without activin (10 ng/ml) treatment for 12 hours, and control vs activin treated cells were compared both for wildtype and knockout. This was performed in a square design.

TranscriptomicsOncogenic SDH mutation underlies global epigenomic instability in gastrointestinal stromal tumor
We have discovered a striking connection between mitochondrial dysfunction and epigenomic instability, manifested by global biallelic DNA cytosine 5-methylation and loss of 5-hydroxymethycytosine within succinate dehydrogenase (SDH)-null gastrointestinal stromal tumors (GIST) relative to those beari...

TranscriptomicsMurine: papillary thyroid cancer vs. poorly differentiated thyroid cancer
Mice with thyroid-specific expression of oncogenic BRAF (Tg-Braf) develop papillary thyroid cancers (PTC) that are locally invasive and have well-defined foci of poorly differentiated thyroid carcinoma (PDTC). To investigate the PTC-PDTC progression, we performed a microarray analysis using RNA fro...

TranscriptomicsT cell UTX promotes Tfh-mediated clearance of persistent virus infection
Epigenetic changes, including histone methylation, control T cell differentiation and memory formation, though the enzymes that mediate these processes are not clear. We show that UTX, a histone H3 lysine 27 (H3K27) demethylase, promotes the generation of T follicular helper (Tfh) cells, a CD4+ T ce...
