Human Embryonic Stem Cells Polysomes

ABSTRACT: H1s are induced to differentiate into the trophoblast (TE) lineage, and polysome analysis performed at 0hr (Undifferentiated), 12hr TE and 24hr TE. The whole cell extract (WCE) is a cytoplasmic lysate of the cell . G1-G4 represent RNAs that were found in different fractions of a sucrose gradient, which represents monosomes, polysomes, etc. Thus the WCE is used as the denominator so that for a particular transcript, we can express G1, for example, as a fraction of the total RNA.

LIN28 function is fundamental to the activity and behavior of human embryonic stem cells (hESCs) and induced pluripotent stem cells. Its main roles in these cell types are the regulation of translational efficiency and let-7 miRNA maturation. However, LIN28-associated mRNA cargo shifting and resultant regulation of translational efficiency upon the initiation of differentiation remain unknown. An RNA-immunoprecipitation and microarray analysis protocol, eRIP, that has high specificity and sensit ...[more]

Mouse cardiac tissue, polysomes and monosomes: Vehicle treated control vs. 25mg/kg DMNQ

Project description:Translational profiling of mouse cardiac tissue treated with 25mg/kg DMNQ in 10 ml/kg arachis oil over an acute time course (0.5-120 hours) compared to time matched control animals treated with 10ml/kg saline Two colour microarrays with time matched controls vs 25mg/kg DMNQ cardiac tissue. Before microarray analysis RNA separated on a sucrose density gradient into those mRNAs activitly undergoing translation (polysomes) and those not (monosomes) with control monosomes and treated monosomes on one set of arrays, and polysome control and polysome treated on another set of microarrays. The normalized Log2 of the monosomes was subtracted from the respective Log2 of the polysomes (on Series record). Time points studied were 0.5, 1, 2, 12, 24 and 120 hours following dosing, biological replicates n=3 independent animals at each time point, technical replicates (reverse labelling) n<1. One array printed onto two slides (A and B), one replicate per array.

Characterization of G-quadruplexes in the rice genome

Project description:DNA G-quadruplex (G4) is a non-canonical four-stranded nucleic acid structure functioning in various biological processes in mammals. G4 ChIP-seq assay, In this study, we developed a robust BG4-DNA ChIP-seq for global identification of DNA G4 in rice..We found that G4s harbored some functional motifs for binding of certain trans-factors, were co-localized with R-loops and DHSs in the rice genome. Importantly, G4s exhibited differential effects on DNA methylation between TE and non-TE genes in rice. Especially, G4 intensity-dependent enrichment occurred between DNA 5mC and 6mA.These DNA-related features suggest potential regulatory roles of G4 in rice. Thus, our study will pave the way for prompting intensive characterization towards identifying novel functions of G4 in plants, especially for agronomic important crops.

RNA-seq of Trypanosoma brucei polysomes in response to ZC3H5 RNAi knockdown

Project description:ZC3H5 was knocked down in bloodstream form T.brucei by RNAi for 0h and 12h. WT bloodstream form cells were used as control. Polysome fractionation was performed, RNA was purified from each fraction and fractions were pooled the following: F=free fraction; M=monosomes; L=light polysomes; H=heavy polysomes. RNA was depleted and RNA-Seq was performed.

Gene Expression data from Mouse Balb/c Bone marrow derived macrophages infected by the promastigote form of Leishmania major parasite (P) or Killed parasite (Kp) during a time course of infection [Balb/c]

Project description:We analyzed the transcriptional signatures of mouse bone marrow-derived macrophages (BMDM) at different times after infection with promastigotes of the protozoan parasite Leishmania major. GeneChip Mouse Gene 1.0 ST arrays were used to analyse global changes in gene transcripts to generate a pool of genes that was statistically significant (p-value < 0.05) and a fold change cut-off of 1.5 in at least one of the five infected samples versus non-infected samples. Three independent biological replicates for each biological condition (Non infected "NI", infected with lived parasite "P" or "heat inactivated parasite "Kp") at 1h (T1), 3(T3), 6(T6), 12 (T12) and 24hours (T24) were performed. The Non infected (NI) at 0 hour (T0) biological condition were used as an additional control.

H2A.Z Mapping During G0/G1 and Mitosis

Project description:We report genome wide mapping of the histone variant H2A.Z during G0/G1 and mitosis in T24 bladder cancer cells. The results show that the broad enrichment pattern of H2A.Z near transcription start sites of active genes is maintained during mitosis. Furthermore, using H2A.Z localization to visualize nucleosome positioning near the start site, we see that the +1 nucleosome of active genes shifts upstream to occupy the transcription start sites during mitosis and the nucleosome depleted region is shortened. H2A.Z is also maintained on the -2 nucleosome which also shifts towrds the transcription start site during mitosis, further contributing to the shorteneing of the nucleosome depleted region. Examination of H2A.Z duing G0/G1 and mitosis in bladder cancer cells
