Zebularine effect on mouse embryonic stem cells manifested as cardiod-myogenic potential: testable hypothesis generation using microarray data

ABSTRACT: Lineage commitment during Embryonic Stem Cells (ESCs) differentiation is controlled not only by a gamut of transcription factors but also by epigenetic events, mainly histone deacetylation and promoter DNA methylation. Moreover, the DNA demethylation agent 5′-Aza-2′-deoxycytidine (AzadC) has been widely described in the literature as an effective chemical stimulus used to promote cardiomyogenic differentiation in various stem cell types; however, its toxicity and instability complicate its use. Thus, the purpose of this study was to examine the effects of zebularine, a stable and non-toxic DNA cytosine methylation inhibitor, on ESCs differentiation. Herein are the Affymetrix Expression data obtained from RNA of murine ESCs treated with zebularine. 9 control samples (replicates) and 9 zebularine samples (replicates).

Temporal dependency of the transcriptional response to carbohydrate depletion contrasts with conservation of the rapid response to sucrose readdition

Project description:To investigate whether the transcriptional response to carbon (C) depletion and sucrose re-addition depend on the duration of C-depletion, Arabidopsis thaliana seedlings growing in liquid culture in weak continuous light were harvested 3, 6, 12, 24, 48 and 72 h after removing sucrose from the medium, and 30 min after resupplying sucrose at each of these times. After removing sucrose, soluble sugars fell strongly within 3 h, and starch was gradually depleted over 24 h, and hexose phosphates and ATP declined gradually over 72 h. Expression profiling using ATH arrays pointed to Overall the transcriptional response pointed to early transcriptional remodelling of metabolism to conserve C, followed by induction of photosynthesis and pathways that recycle C, and repression of growth-related processes. The time-dependent transcriptional response to C-depletion differed from that during a light/dark cycle and an extended night. Re-supplying sucrose for 30 min led to near-complete recovery of seedling sucrose levels, partial recovery of reducing sugars and phosphorylated intermediates, but no immediate change of starch or ATP. The rapid transcriptional response to sucrose readdition was conserved across the entire C-depletion time course, became larger with time. , and was highly enriched for regulatory genes. Whilst there was a rapid decrease of many C-depletion-induced transcripts, fewer transcripts increased. The majority of the transcripts that responded rapidly after resupplying sucrose also decreased after treating C-depleted seedlings with the transcriptional inhibitor cordycepin A, pointing to an important role for transcript turnover in the rapid response to sucrose.

Gene expression microarray analysis of whole intestine from Kaiso-/- mice

Gene expression during first day of collagen gel culture of rat aortic rings

Project description:Angiogenesis in collagen gel cultures of rat aorta begins with neovessels sprouting from the aortic explant within the first three days of culture. We used microarrays to detail the pattern of gene expression underlying initial 24 hours of growth, prior to the sprouting of visible neovessles, and identified distinct classes of up-regulated genes during this process. Either freshly harvested aortic rings, representing day 0, or collagen gel cultures of rat aorta were grown in serum free medium and used to prepare total RNA.

Gene expression in TNF treated rat aortic rings cultured in collagen or fibrin gels.

Project description:Angiogenesis in cultures of rat aorta begins with neovessels sprouting from the aortic explant within the first three days of culture. We used microarrys to examine the effects of TNF-alpha on gene expression in both fibrin and collagen gels during the first 48 hours or culture. Rat aortic rings were cultured in either collagen or fibrin maticies. Half of the cultures from each matrix group were treated with 10ng/ml recombinant rat TNF-alpha, and half were left untreated. These cultures were used to prepare total RNA

Sugar-dependent gene expression in xylose grown A. thaliana cell suspension culture

Project description:Sugars modulate expression of hundreds of genes in plants. Previous studies on sugar signaling, using intact plants or plant tissues, were hampered by tissue heterogeneity, uneven sugar transport and/or inter-conversions of the applied sugars. This, in turn, could obscure the identity of a specific sugar that acts as a signal affecting expression of given gene in a given tissue or cell-type. To bypass those biases, we have developed a novel biological system, based on stem-cell-like Arabidopsis suspension culture. The cells were grown in a hormone-free medium and were sustained on xylose as the only carbon source. The functional genomics approach was used to identify sugar responsive genes, which rapidly (within 1 h) respond specifically to low concentration (1 mM) of glucose, fructose and/or sucrose. A habituated A. thaliana cell culture grown in a hormone free full strength MS media in the dark was adapted to growth on xylose as the only carbon source in the media.The cells were subjected to a 1 hour treatment with 1 mM of either Fru, Glc, Suc or Xyl (control). The experiments were carried out in 3 biological repeats per treatment. Whole genome expression analysis was conducted by hybridization of the extracted RNA to the Affymetrix Arabidopsis ATH1 Genome Array.

Genome-wide expression analysis of quiescent versus activated muscle stem cells (satellite cells)

Project description:We performed genome-wide gene expression analysis of quiescent/activated muscle stem cells isolated from mouse skeletal muscle by flow cytometry. We analyzed the global changes in gene expression occurring within muscle stem cells (satellite cells) in homeostatic conditions or after cardiotoxin (CTX) injury (3 days). Pure satellite cell populations from dissociated skeletal muscle from mice were isolated using a well-established flow cytometry protocol gating on integrin a7(+) (positive selection) and Lin- (CD31, CD45, CD11b, Sca1) (negative selection).

MKL1-dependent tenascin-C transcription

Project description:The aim of the experiment is to investigate whether megakaryoblastic leukemia factor-1 (MKL1) induces tenascin-C in normal mammary epithelial HC11 and tumor mammary epithelial 4T1 cell lines, as well as to identify other genes that are transcriptionally regulated by MKL1. For this purpose, we compared the transcriptomes of HC11 and 4T1 cell lines stably expressing the full length (FL) MKL1 protein (HC11-FL and 4T1-FL cell lines) to respective control cell lines stably transfected with an empty vector (HC11-control and 4T1-control cell lines).

Investigating epigenetic effects of activation-induced deaminase in chronic lymphocytic leukemia

Project description:Activation induced deaminase (AID) has two distinct and well defined roles, both relying on its deoxycytidine (dC) deaminating function: one as a DNA mutator and another in DNA demethylation. In chronic lymphocytic leukemia (CLL), AID was previously shown to be an independent negative prognostic factor. While there is substantial impact on DNA mutations, effects of AID on gene expression by promoter demethylation of disease related target genes in leukemia has not been addressed. To shed light on this question, we aimed at determining genome wide methylation changes as well as gene expression changes in response to AID expression in CLL. Although we found minor differences in individual methylation variable positions following AID expression, we could not find recurrent methylation changes of specific target sites or changes in global methylation.
