We present a method for deconvoluting expression from a heterogeneous sample into components that reflect the contributions to the observed expression attributable to each component cell or tissue type.
Consistent with this is the observed expression of genes to obtain and metabolize all available nitrogen sources.
The figures show quantile-quantile plots (Q-Q plots), comparing the observed expression values to the corresponding values of the inverse normal cumulative distribution.
While acknowledging the genetic evidence for precocious X inactivation [ 3, 7], the authors interpret the observed expression pattern to be inconsistent with the predictions of MSCI.
The peak around PCC = 0.2 observed in MAS5 and PLIER was derived from genes with low expression level (data not shown), where noises in microarray experiments may strongly affected the observed expression patterns to calculated gene coexpression.
However, cell proliferation along the anterior posterior axis is relatively uniform in the E13.5 palate (Bush and Jiang, 2012), complicating assignment of the observed expression patterns to a spatially restricted proliferation program.
As mRNA levels are not only known to be regulated by 5'UR TFBSs, but also post-transcriptionally by regulatory elements in the 3'untranslated region (UTR), we were interested in relating the observed expression differences to putative 3'UTR regulatory sequences.
Since the cultivation parameters, such as the employed carbon source, are closely linked to the actual molecular signals that are detected by the cell, it may be possible to also relate transporters and signaling cascades to the observed expression under different environmental conditions.
Contrary to the observed expression of Cnr1 in small intestinal L cells, we observed no effect of the CB1 ligands on IBMX-stimulated GLP-1 secretion from the small intestine (Fig. 5b, c).
In addition, it is impossible to attribute observed differential expression to individual cell types.
Possibly, the activation of MPCs may contribute to the observed expression of this alternative splice variant.
