To understand immune suppression in mice with genetically distinct pregnancies, the researchers examined
gene expression patterns in immune cells during infection.
The research also showed that
gene expression patterns of individual tumors varied considerably, and could exceed the variation observed between different cancer types.
She and her colleagues propose that other replication inhibitors to fight cancer will also produce unique double strand break profiles,
as gene expression patterns would dictate the locations of replication - transcription conflicts.
At each developmental stage, the researchers conducted single - cell RNA sequencing to identify
unique gene expression patterns and assess the purity of individual cell populations.
This work shows the power of using the tools of computational genomics to analyze
gene expression patterns for the purpose of elucidating the evolution of behavior.
Since regeneration recapitulates in broad strokes embryonic development, during which a complex multi-cellular organism develops from a handful of embryonic stem cells, the researchers began by
comparing gene expression patterns between the two processes.
Comparison of the transcripts revealed that breast cancer cells with knockdown of ABL2 alone shared a
similar gene expression pattern with that of the ABL1 / ABL2 double - knockdown cells (Fig. 6A and fig.
Recent advances in the understanding of cancer have led to more personalized therapies, such as drugs that target particular proteins and tests that
analyze gene expression patterns in tumors to predict a patient's response to therapy.
Collectively, these results suggest that increased rates of DNA turnover have had little impact on
altering gene expression patterns, since the majority of DNA turnover in these regions surrounding developmental genes has likely not interrupted regulatory element architecture.
Dr. Hardison noted that the opposite is also true: researchers need to take into account systematic differences in
gene expression patterns between the species when considering the mouse as a model for humans.
«This is the first demonstration, to our knowledge, of successful quantitative predictions of the individual behavioral state
from gene expression patterns in the brain of a mammal,» says Miyakawa.
A further 25 days in medium containing FGF2 and Noggin mediated the derivation and expansion of RPCs which had a similar
global gene expression pattern to cells of the embryonic day 14 (E14) mouse retina.
By
examining gene expression patterns, the new study found that parrot brains are structured differently than the brains of songbirds and hummingbirds, which also exhibit vocal learning.
Analysis of
liver gene expression patterns of the exposed rats found that the endocrine disruptors induced developmental reprogramming of the animals» epigenomes.
For Helicobacter pylori, a pathogenic bacterium that colonizes over 40 percent of the world population and is associated with gastric cancer, the team discovered that epigenetic heterogeneity can quickly emerge as a single cell divides, and different subpopulations with distinct methylation patterns have
distinct gene expressions patterns.
Results show that one night of partial sleep deprivation
activates gene expression patterns in peripheral blood mononuclear cells (PBMCs) consistent with increasing accumulation of damage that initiates cell cycle arrest and increases susceptibility to senescence.
«Gene analysis adds layers to understanding how our livers function:
Tracking gene expression patterns for 20,000 gene in 1,500 cells revealed a mosaic of activities.»
Their microbial exposures varied and
gene expression patterns varied, but the parts of the genome that were open at each location in the gut remained consistent, Crawford said.
We're now able to recapitulate that process and begin to study things
like gene expression patterns and the distinct steps involved in this process.»
The «gene expression in tooth database»
contains gene expression patterns of different cells and compartments of the tooth at distinct time points, as determined by in situ hybridization or by immunostaining.
Now researchers at the Salk Institute for Biological Studies have identified an essential cellular pathway in zebrafish that paves the way for limb regeneration by
unlocking gene expression patterns last seen during embryonic development.
IMPRINTOME STOP SIGNS:
Gene expression patterns for 42 imprinted genes (y axis) vary across diverse tissues (x axis), with redder boxes denoting stronger skewing towards just one allele.
In collaboration with Yi Xing from UCLA, the team catalogued and analyzed
how gene expression patterns in skin cells differed among the Esrp knockouts and found hundreds of significant changes.
