Introduction
+
This notebook contains the code used to generate the results and plots of the ExPECT study. The code is fully reproducable using the data from the github repo. You can navigate through this page by using the bar on the right side. Code chunks are collapsed by default. To look at the code that generated a certain figure, click on the greyed out Code titles. Like the one below this text, that chunk contains all packages and some helper functions/utilities that were used.

Data loading
+
A bsseq object and .Rds file containing normalized and clustered methylation values for the samples included is first loaded along with the annotation files. Both methylation data objects are generated by running the smooth_and_cluster.R script from the Scripts folder of this repo on bismark.cov files, which are generated with the nf-core/methylseq pipeline. The pre-processing performed by the aformentioned script creates CpG clusters from the CpGs present in at least 50% of the samples. Methylation values are normalized and smoothed after which they are mapped to the clusters. Methylation values are then averaged across each cluster.
+
+
+Code
+
#Load bsseq object
+bs_expect <-loadHDF5SummarizedExperiment(dir ="Data/Methylation")
+
+#Load clustered methylation data
+clusters_expect <-readRDS("Data/Methylation/clusters_expect.Rds")
+
+#Load study annotation
+annotation <-read_csv("Data/expect_annotation.csv")
+long_samples <-read_table("Data/longitudinal_samples.txt")
+
+
+#Split up annotations for ease of use
+
+long_annotation <- annotation %>%filter(Sample_id %in% long_samples$Sample_id)
+presympt_annotation <- annotation %>%filter(Group =="Pre-symptomatic")
+sympt_annotation <- annotation %>%filter(Group =="Symptomatic") %>%
+filter(Sample_id %nin% long_annotation$Sample_id)
+
+#Split up clusters for ease of use
+clusters_presympt <- clusters_expect %>%select(all_of(presympt_annotation$Sample_id))
+clusters_sympt <- clusters_expect %>%select(all_of(sympt_annotation$Sample_id))

Box-plots showing the mean genomic methylation level of controls and preeclampsia cases (PE). Methylation levels from presymptomatic samples, sampled between 11 and 20 weeks of gestation, show no significant difference. Methylation levels between cases and controls sampled after 20 weeks of gestation show a significantly lower methylation level of cases compared to controls. Significant methylation differences between pre-symptomatic and symptomatic groups can be observed for both preeclampsia cases and controls.
+
+
+
+
DMR calculation
+
To define the methylation difference between PE and control samples DMR’s are calculated in two ways. In the first method the ad hoc defined CpG clusters are used and a limma model is generated to calculate clusters that are DMR’s. Clustering based on these DMR’s can be seen below, use the tabs to select the number of DMR’s used for clustering. As seen in the the largest difference can be observed between early pre-symptomatic samples and later symptomatic samples, therefore these two groups are also used separately for DMR calculation. DMR calculation on the entire dataset does not yield any significant DMR’s between PE and control groups.
+
+
+Code
+
#DMR calculation with limma
+dmr_design <-model.matrix(~Category + Batch + Sex, annotation)
+dmr_clusters_limma <-train_limma(clusters_expect, dmr_design) #This function is defined in the first code block
+#DMR calculation on the entire set does not yield any significant DMR's
+
+#Pre-symptomatic DMRs
+
+dmr_design_presympt <-model.matrix(~Category + Batch + Sex, presympt_annotation)
+dmr_presympt_limma <-train_limma(clusters_presympt, dmr_design_presympt)
+#DMR calculation on the presymptomatic set does not yield many significant DMR's
+
+#Symptomatic DMRs
+
+dmr_design_sympt <-model.matrix(~Category + Batch + Sex, sympt_annotation)
+dmr_sympt_limma <-train_limma(clusters_sympt, dmr_design_sympt)
+dmrs_sympt_limma<- dmr_sympt_limma$CategoryPE %>%filter(abs(logFC) >0.1) %>%filter(adj.P.Val <0.01) %>%rownames()
+
+
+
+
Clustering
+
Heatmap plots are made to show the significance of the discovered DMR’s, switch between the amount of DMR’s used to generate the heatmap by using the tabset. The rows of the heatmaps represent samples, while columns represent the DMR’s. Methylation values are shown on a gradient from blue to white to purple (with blue hues being <50% methylated regions and purple hues meaning >50% methylated regions).
As finding significant DMR’s in the pre-symptomatic cohort proved unsuccesfull with the ad hoc clustering method, a second approach using DMRfinder is tried. This approach yields a set of significant DMR’s for the early sampling period.
Heatmap plots are made to show the significance of the discovered DMR’s, switch between the amount of DMR’s used to generate the heatmap by using the tabset. The rows of the heatmaps represent samples, while columns represent the DMR’s. Methylation values are shown on a gradient from blue to white to purple (with blue hues being <50% methylated regions and purple hues meaning >50% methylated regions)
To explore enriched GO terms the goana package is used to perform a gene ontology analysis on the discovered DMR’s. This is done three separate times, once on the genes in the presymptomatic set of DMR’s, once on the genes in the symptomatic set of DMR’s and a final time on the set of overlapping genes that are present in both sets of DMR’s.

Mean whole genome methylation follows a similar trend for preeclampsia patients and controls across pregnancy duration. At 11-13 weeks of GA, a lower global methylation is noted for preeclampsia cases (A) . Methylation of two preeclampsia related genes, sFLT-1 (B) and PIGF (C) follows slightly different patterns for controls and preeclampsia patients, ending at a lower methylation level in preeclampsia patients compared to controls.
+
+
DMR’s in the longitudinal cohort
+
Due to the small overlap between DMR’s calculated on the pre-symptomatic and symptomatic cohorts, we hypothesize that these DMR’s also undergo significant changes throughout the pregnancy duration. To investigate this groups of DMR’s are extracted from the hierarchical clusterings made in the heatmap figures of the DMR section. The average methylation of these groups is then investigated over time.

A total of 73 DMR’s are found to be significant between cases and controls that are independent of the gestational age of the sample. These DMR’s arent able to fully make a destinction between cases and controls for all included samples.
