Project description:Skeletal muscle C2C12 cells were treated with or without trichostatin A (TSA), which induces differentiation. Total RNA was extracted and profiled at 5 time points after induction of differentiation (0, 4h, 12h, 24h, 48h). Keywords: other
Project description:Human pluripotent stem cells (hPSC) offer a unique cellular model to study the molecular details underpinning embryonic development. We profiled single-cell RNA-seq (scRNA-seq) on 957 single cells collected at 6 time points over a 30-day period of non-directed differentiation of human neural progenitor cells (NPC) generated from hESC. Computational and experimental analyses of this comprehensive data set enabled us to: 1) define distinct subpopulations of developing neurons and their specific gene expression patters; 2) elucidate alternative cell developmental trajectories within discrete time points of the differentiating populations; and 3) decipher gene regulatory networks and validated key regulators (transcription factors and lincRNAs) that dictate alternative cell fate specifications. In this submission, 957 bam files are provided: 1) 573 single cells from time course profiling (day 0, 1, 5, 7, 10, 30) as first batch and 2) 384 single cells from time course profiling (day 0, 3, 7, 14) as second batch.
Project description:Young adult C57 mice were exposed to chronic hypoxia for up to 2 weeks. Control mice were maintained under normoxic conditions To capture the temporal effect of reduced oxygen tension on gene regulation, we sampled and gene profiled the soleus hindlimb muscle (n=4) at 4 different time-points (day 0, 3, 7 and 14) following initiation of the gradual hypoxic insult (i.e. the O2 level was gradually lowered to 10% over the first week and kept stable during the second week).
Project description:The experiment shows the transcriptional changes between mouse trophoblast stem cells transduced with non-targeting single-guide RNA (NT-sgRNA) or sgRNA against the promoter of the Bap1 gene (sgRNA1) at two different time points, 0 days (0d) -stem cell conditions- and after 3 days (3d) of differentiation
Project description:We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). At each stage, the fetal placenta and maternal decidual tissues were dissected and profiled separately Keywords: time course
Project description:During human pregnancy, cytotrophoblasts (CTBs) from the placenta differentiate into specialized subpopulations that play crucial roles in proper fetal growth and development. A subset of these CTBs differentiate along an invasive pathway, penetrating the decidua and anchoring the placenta to the uterus. A crucial hurdle in pregnancy is the ability of these cells to migrate, invade and remodel spiral arteries, ensuring adequate blood flow to nourish the developing fetus. Although advances continue in describing the molecular features regulating the differentiation of these cells, assessment of their global proteomic changes at mid-gestation remain undefined. Here, using sequential window acquisition of all theoretical fragment-ion spectra (SWATH), which is a data-independent acquisition strategy, we characterized the protein repertoire of second trimester human CTBs during their differentiation towards an invasive phenotype. This mass spectrometry-based approach allowed identification of 3026 proteins across four culture time points corresponding to sequential stages of differentiation, confirming the expression dynamics of established molecules and offering new information into other pathways involved. The availability of a SWATH CTB global spectral library serves as a beneficial resource for hypothesis generation and as a foundation for further understanding CTB differentiation dynamics.
Project description:Mass spectrometry analysis was carried out to investigate the protein expression landscape of RNA-binding proteins (RBPs) during a time-course of spontaneously differentiating human embryonic stem cells (hESCs). Mass spectrometry was performed on whole-cell extracts of differentiating TE03 (I3) hESCs at four time-points (days 0, 23, 39, and 54), each with two biological replicates.
Project description:We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). For these samples, at each stage the fetal placenta and maternal decidual tissues were dissected and profiled separately (See series 1). For this experiment (Series 2), placental and decidual timecourse samples were normalized and modeled with two undissected (including placental and decidual tissue) e17 placentas to allow for scaling of values for comparison to the undissected placenta samples used in the publicly available mouse GeneAtlas dataset Keywords: time course
Project description:We used full genome microarrays to profile the full lifetime of the mouse placenta from embryonic day 8.5 (e8.5), at the time of chorioallantoic fusion, until postnatal day 0 (P0). At each stage, the fetal placenta and maternal decidual tissues were dissected and profiled separately Experiment Overall Design: Mouse placentas were obtained from timed pregnant female mice at each timepoint, and fetal tissues were used to confirm embryo staging. Fetal placenta and maternal decidual tissues were dissected and pooled separately for each litter prior to RNA extraction and hybridization on Affymetrix microarrays.
Project description:These are the 94 microarray experiments that are published in the paper: John Wang and Stuart K. Kim. Global analysis of dauer gene expression in Caenorhabditis elegans, Development 2003 130: 1621-1634. There are 94 individual microarray experiments divided into 3 broad experiments. The first experiment is a time course of dauer exit; each time course is labeled as "Dauer MTC#". The second experiment is a time course of L1 development after starvation arrest; each time couse is labeled "L1 MTC#". The final experiment is a comparison of pure dauers (0 hours) versus 12 hours after dauer exit and are labeled "Dauer Adjust". Every time course was repeated 4 times (#N)however for the dauer 4 and 7 hour time points there are only 3 replicates. For instance, all the time points labeled as "Dauer MTC#1" are from the same starting pool of dauer worms that were aliquoted into 10 fractions and analyzed at the time indicated. Every sample is compared to a common reference RNA that is used throughout all the hybridizations. In some cases there is a "-2" after the hour designation; this means the first hybridization failed for some technical reason and thus the second hybridization (same RNA) is reported.
