Previous investigations suggest that the different embryonic origins of the calvarial tissues (neural crest or mesoderm) may account for the different molecular mechanisms underlying sutural development. The aim of this study was to evaluate the differences in the gene expression of human cranial tissues and assess the presence of an expression signature reflecting their embryonic origins. Using microarray technology, we investigated global gene expression of cells from the frontal and parietal bones and the metopic and sagittal intrasutural mesenchyme (ISM) of four human fetal calvaria.
Transcriptional analysis of human cranial compartments with different embryonic origins.

View SamplesSeven novel and potent Raf small molecule kinase inhibitors were evaluated in 7-day oral repeat-dose rat toxicity studies. All compounds tested induced hyperplasia in multiple tissues. Microarrays were used to investigate transciptional changes associated by treatment with a single compound to gain insight into the cellular changes that may contribute to the tissue hyperplasia.

View SamplesUterine receptivity implies a dialogue between the hormonally primed maternal endometrium and the free-floating blastocyst. Endometrial stromal cells proliferate, avert apoptosis, and undergo decidualization in preparation for implantation; however, the molecular mechanisms that underlie differentiation into the decidual phenotype remain largely undefined. The Notch family of transmembrane receptors transduce extracellular signals responsible for cell survival, cell-to-cell communication, and trans-differentiation, all fundamental processes for decidualization and pregnancy. Using a murine artificial decidualization model, pharmacological inhibition of Notch signaling by gamma-secretase inhibition resulted in significantly decreased deciduoma. Furthermore, a progesterone receptor (PR)-Cre Notch1 bigenic (Notch1d/d) confirmed a Notch1-dependant hypomorphic decidual phenotype.
Notch1 mediates uterine stromal differentiation and is critical for complete decidualization in the mouse.

View SamplesWe used PacBio data to identify more reliable transcripts from hESC, based on which we can estimate gene/transcript abundance better from Illumina data. Overall design: PacBio long reads and Illumina short reads were generated from the same hESC cell line H1. PacBio reads were error-corrected by Illumina reads to identify transcripts. rSeq is used to estimate gene/transcript abundance of the identified transcriptome.

View SamplesTo understand the differentiation of effector Tregs in more detail, we have performed transcriptional profiling of central Tregs and effector Tregs, based on Blimp1 expression. We performed RNA-sequencing of Foxp3+ regulatory T cells, comparing Blimp1/GFP+ and Blimp1/GFP- cells Overall design: Three biologically independent samples for each condition were sequenced (condition 1: CD4+ CD25high Blimp1/GFP+; condition 2: CD4+ CD25high Blimp1/GFP-); cells were sorted from pooled spleens and lymphnodes of Blimp1/GFP reporter mice
