Sentence examples for based on mean expression from inspiring English sources

Kaplan-Meier survival functions and log-rank test were used to assess progress-free survival and overall survival time based on mean expression levels of 6 miRNAs.

For the given data sets, Affymetrix did not show as prominent variation in expression levels as the cDNA data set, yet the method represents a useful control in absence of a gold standard and a valuable alternative to the standard method based on mean expression levels.

Here, e.g. genes 7 and 8 were each measured by two probe sets showing opposite regulation with unequal probe set p-values, and both spots show similar intensity levels; for these genes Stouffer's method returns p-values similar to those determined based on mean expression values.

For all genes represented by at least 2 spots (sub-plot a), Stouffer's method yields results that are most similar to the chi-square method and the variant thereof while p-values based on mean expression values are rather similar to the minimum of the underlying spot p-values.

CXCL9, CXCL10, CXCL11 and CCL5 were co-expressed and, when used for hierarchical clustering analysis based on mean-centered expression values, segregated melanoma metastases into three main groups: cluster 1 included samples with low CXCR3 and CCR5 ligand gene expression; cluster 2 and cluster 3 with intermediate and high expression, respectively.

Gene expression profiles were measured by expression breadth (taking into account the number of tissues in which each gene is expressed) and expression level (based on mean microarray hybridization signals measured for the probe sets corresponding to each locus).

In this part, we perform analyses for the proposed LTVFF-DRLS and LCTVFF-DRLS algorithms based on mean square performance and derive expressions for the steady-state MSD and EMSE, which are defined as begin{aligned} {MSD}_{k}^{ss}&={lim}_{itoinfty}Eleft[|widetilde{mathbf{w}}_{k,i}|^{2}right] {EMSE}_{k}^{ss}&={lim}_{itoinfty}Eleft[|mathbf{u}_{k,i}^widetilde{mathbf{w}}_{k,i-1}|^{2}right].

A Friedman test based on means of HKG expression for each oxygen concentration indicates that HKG variation is statistically significant between different oxygen concentrations in PNT2 (P=0.0006), LNCaP (P<0.0001) and HEK (P<0.0001) cell lines.

The analysis of differential gene expression is based on the mean expression change of individual genes.

'Corvina' expression atlas, which were normalized based on the mean expression value of each gene in all tissues/organs analysed, all other expression data were calculated as log2 fold change in treated vs. untreated samples.

Each patient's tumour sample was classified using a correlation coefficient based on the mean expression value of each selected gene for the pCR and non-pCR subsets.
