Meaghan J. library consisting of 300 CpGs (Additional file 5: Table S3) performed favorably both with respect to its average ranging from as low as 0.97 % for monocytes to 1 1.37 % for CD4T cells (Fig. ?(Fig.33?3c).c). Across the six leukocytes, the average between the predicted and flow cytometry cell type proportions were estimated at 0.99 and 1.15 %, respectively. When compared to the results obtained from the application of both the EstimateCellCounts and TopANOVA libraries to training set (Fig. ?(Fig.11?1dd,?,e,e, Additional file 2: Figure S1), the IDOL library resulted better Beclometasone dipropionate prediction performance for all cell types except B cells, whose predictions from EstimateCellCounts exhibited slightly lower (0.98 % versus 1.04 %). Upon further comparison, the greatest improvements in prediction performance associated with the IDOL library occurred for monocytes and among lymphocyte subtypes. Specifically, the IDOL library resulted in monocyte predictions that explained approximately 70 %70 % more variation in the flow cytometry measurements of monocytes compared to EstimateCellCounts (Figs. ?(Figs.11?1ee and ?and33?3c).c). Rabbit Polyclonal to MC5R Similarly, predictions of CD4T, CD8T, and NK cell type fractions obtained from the IDOL library explained an average of 17 % more variation in the flow cytometry derived fractions of these cell types compared to EstimateCellCounts, and were associated with =0.038) (Fig. ?(Fig.33?3f).f). Furthermore, a comparison of the DSC values computed between each pair of leukocytes showed that the IDOL library Beclometasone dipropionate resulted in larger DSC values in 14 out of the 15 comparisons, of which 4 were associated with computed across Beclometasone dipropionate the testing sets showed that in 4 out of Beclometasone dipropionate the 6 cell types, predictions were, on average, within 2.0 % of their true reconstructed mixture proportions. The two exceptions being NK cells (=2.5 =3.4 ranged between [0.86, 1.00] and [1.09 %, 4.11 %] with mean values of 0.96 and 2.14 %, respectively. Similarly, in the MethodB data set, cell-specific ranged between [0.82, 0.98] and [1.44 %, 2.52 %] with mean values of 0.91 and 1.68 %. Furthermore, there appeared to be no association between the prediction performance of a given cell type and its true underlying fraction in the MethodA and MethodB reconstructed mixture samples (Additional file 7: Figure S3, Additional file 8: Figure S4 and Additional file 9: Figure S5). The prediction performance obtained using the IDOL library compared favorably to the performance associated with EstimateCellCounts, the predictions of which explained, on average, 2 % less variation in the underlying reconstructed mixture fractions compared to the IDOL library (Additional file 6: Table S4 and Fig. ?Fig.44?4c).c). The largest difference in performance was observed for CD4T cells, whose IDOL associated predictions explained an estimated Beclometasone dipropionate 12 % more variation in the reconstructed mixture proportions of CD4T cells and were associated with a 2-fold lower compared to EstimateCellCounts (Additional file 6: Table S4 and Fig. ?Fig.44?4cc). Implications of cell composition adjustment methodology for EWAS In the overwhelming majority of the studies using CMD, estimates of immune cell fractions are first obtained for each study sample, followed by their inclusion as additional covariate terms in statistical models to control for the potential confounding effects of cellular heterogeneity [26C28]. For this reason, metrics such as Bioconductor package (http://bioconductor.org). Every beta-value on the HumanMethylation450 array platform is accompanied with a detection principal components (determined using a previously described approach ) were examined in terms of their association with plate and BeadChip. If plate and/or BeadChip was found to be.
