We check the scree plot to choose ten dimension as the intrinsic dimensions to reconstruct the developmental trajectory for the Paul dataset (cells used in Figure 1 of the original study9 (link)). Five branch points and six terminal lineages (monocytes, neutrophils or eosinophil, basophils, dendritic cells, megakaryocytes, and erythrocytes) are revealed. We ordered the cells using genes Paul et al. used to cluster their data rather than the genes from dpFeature, for the sake of consistency with their clusetering analysis. Similarly, we reconstruct Olsson datasets in four dimensions. The major bifurcation between the granulocyte and monocyte branch (GMP) as well as the intricate branch between GMP and megakaryocyte/erythrocyte (Ery/Meg) are revealed. Top 1, 000 genes from dpFeature based on WT cells are used in both of the WT and full datasets. The distribution (related to confusion matrix) of percentages of cells in each cluster from the original papers over each segment (state in Monocle 2) of the principal graph are calculated and visualized in the heatmap.
We applied BEAM analysis to identify genes significantly bifurcating between Ery/Meg and GMP branch on the Olsson wildtype dataset. We then calculate the instant log ratios (ILRs) of gene expression between Ery/Meg and GMP branch and find genes have mean ILR larger than 0.5. The ILRs are defined as:
ILRt=log(Y1tY2t)
So
ILRt is calculated as the log ratio of fitted value at interpolated pseudotime point
t for the Ery/Meg lineage and that for the GMP lineage. Those genes are used to calculate the lineage score (simply calculated as average expression of those genes in each cell, same as stemness score below) for both of the Olsson and the Paul dataset which is used to color the cells in a tree plot transformed from the high dimensional principal graph (see Supplementary Notes). The same genes are used to create the multi-way heatmap for both of the Paul and Olsson dataset (see plot multiple_branches_heatmap function). Critical functional genes from this procedure are identified. Car1, Car2 (important erythroid functional genes for reversible hydration of carbon dioxide) as well as Elane, Prtn3 (important proteases hydrolyze proteins within specialized neutrophil lysosomes as well as proteins of the extracellular matrix) are randomly chosen as example for creating multi-lineage kinetic curves in both of the Olsson and Paul dataset (see plot_multiple_branches_pseudotime function).
In addition, pseudotime dependent genes for the Ery/Meg and GMP branch are identified in the Olsson wildtype dataset. All genes that always have lower expression from both lineages than the average in the progenitor cells are selected. Those genes are used to calculate the stemness score for both of the Olsson and the Paul dataset which is used to color the cells in the tree plot.

Soft clustering has been implemented using the fuzzy c-means algorithm. [5 ] It is based on the iterative optimization of an
objective function to minimize the variation of objects within clusters. Poorly clustered objects have decreased influence on the resulting clusters making the clustering process less
sensitive to noise. Notably this is a valuable characteristic of fuzzy c-means method as microarray data tends to be inherently noisy. As a result, fuzzy c-means produces gradual membership
values µij of a gene i between 0 and 1 indicating the degree of membership of this gene for cluster j. This strongly contrasts
hard clustering e.g. the commonly used k-means clustering that generates only membership values µij of either 0 or 1. Thus, soft clustering can effectively reflect
the strength of a gene's association with a cluster. Obtaining gradual membership values allows the definition of cluster cores of tightly co-expressed genes. Moreover, as soft clustering displays
more noise robustness, the commonly used procedure of filtering genes to reduce noise in microarray data can be avoided and loss of the potentially important information can be prevented. [4 (link)]

The Mendelian Randomization procedure consists of two steps: i) identification of proper instrumental variables or genetic predictors, e.g. variants independently associated with the exposure factor, and ii) calculation of causal estimates. For each GWAS summary statistic, we first selected independent SNPs using the clumping procedure in PLINK v1.9 (see URLs) and setting a linkage disequilibrium threshold of r2 < 0.1 in a 500-Kb window. Linkage disequilibrium was calculated using the LL-DEEP cohort when running the clumping procedure on the GWAS of microbiome features and short chain fatty acids, whereas for GWAS of anthropometric and glycemic traits we used the linkage disequilibrium estimates from the 1000 Genomes phase 3 European samples.
Furthermore, since the majority of the downloaded GWAS were based on the HapMap2 genetic map, for each independently associated variant, we identified the best HapMap2 proxy (r2 > 0.8) or discarded that variant if no proxy was available.
Finally, we selected only variants that showed association at P < 1 × 10−5. We identified this as the optimal P-value threshold to use for selection of genetic predictors associated with microbiome features because this threshold led to a larger variance explained, on average, of the same microbiome features in the 500FG cohort (Supplementary Figure 1). For consistency, we used the same threshold and procedure for selecting genetic predictors from the downloaded GWAS on anthropometric and glycemic traits.
To calculate causal estimates, we used the inverse-variance weighted (IVW) method32 (link) as a two-sample MR analysis of summary association statistics of the exposure and the outcome. Specifically, we estimated the causal effect in a fixed-effect meta-analysis framework, i.e. as a sum of single-SNP causal effects (derived as a ratio of the SNP-effect on the outcome by the SNP-effect on the exposure) weighted by the inverse of their variance (derived as a squared ratio of the SNP-standard deviation on the outcome on SNP-effect on the exposure). The P-value was calculated as P = 2* (1- Φ(Z)), where Φ(Z) is the standard normal cumulative distribution function and Z is ratio of the combined (using inverse variance weights) causal effect and its standard error. Of note, the causal estimate is equivalent to that obtained as a weighted linear regression of the outcome SNP-effects on the exposure SNP-effects with a fixed intercept of 0 and with the inverse of the variance of the effect sizes on the outcome as weights. For analyses, we set the effect allele of the genetic predictors to be the allele with the positive direction. We also calculated causal estimates using additional MR methods: MR-PRESSO30 (link), which removes pleiotropy by identifying and discarding influential outlier predictors from the IVW test and uses a t-test to calculate P-values; the weighted-median test31 (link), which uses a statistical estimator that is robust to the presence of pleiotropy in a subset (< 50%) of the predictors; and the MR-Egger32 (link), which adjusts for average horizontal pleiotropy and assumes that > 50% of the predictors have pleiotropy. Furthermore, we specifically evaluated presence of pleiotropy using MR-PRESSO Global test30 (link) and the modified Rücker’s Q’ test33 .

Notes:

The procedure for phage propagation is largely specific for each phage and bacterial host. Here we use propagation conditions for T4 phage and Escherichia coli B bacterial host. It is recommended to use appropriated growth and propagation conditions for your choice of phage and host.

Once a sufficiently high titer phage lysate is obtained please proceed to step 3.

It is recommended to only propagate and purify one phage at a time to prevent cross-contamination.

1| Phage plaque assay for determination of titer (Adams, 1959 )
2A| Phage isolation and propagation via plate lysate
2B| Phage propagation via liquid lysate
3| Phage cleanup (0.22 μm filtering and chloroform)
4| Phage concentration and wash via ultrafiltration
5| Endotoxin removal (Morrison & Leive, 1975 (link); Szermer-Olearnik & Boratyński, 2015 (link))
Notes:

This method is adapted from Szermer-Olearnik & Boratyński (2015) (link), which demonstrates the efficient removal of endotoxins from bacteriophage lysates using water immiscible solvents that are subsequently removed via dialysis. For detailed explanation of the methodology please see Morrison & Leive (1975) (link) and Szermer-Olearnik & Boratyński (2015) (link).

Our adapted method uses a speed vacuum to remove residual organic solvent from phage lysates, instead of the lengthy dialysis washes with similar efficiency.

This step is optional. If you do not require removal of bacterial endotoxins from your phage preparations please go to step 7.

6A| Dialysis removal of organic solvent (Szermer-Olearnik & Boratyński, 2015 (link))
Notes:

This method is adapted from Szermer-Olearnik & Boratyński (2015) (link) and describes the removal of residual organic solvents from phage lysates by dialysis.

Residual organic solvents disable downstream Pierce™ LAL Chromogenic Endotoxin Quantitation assays and must be removed in order to accurately quantify endotoxin concentrations.

Due to the ionic concentration of phage SM buffer used you may end up with greater than the starting volume.

6B| Speed vacuum removal of organic solvent
Notes:

This method is a faster alternative to the dialysis method for the removal of residual organic solvents from phage concentrates.

The search strings were created by SB and AEB, together with librarians from the University of Queensland, Australia, and the University of Skövde, Sweden. Searches were performed in September 2017 in the following databases: PubMed, Scopus, CINAHL (Cumulative Index of Nursing and Allied Health Literature), and PsycInfo. Additional literature searches using the same search strings were completed in March 2020 and June 2022. The search terms comprise synonyms and database-specific terms for oxytocin AND levels AND blood/plasma AND labour/birth/breastfeeding/interventions/newborns. The full search strings are available in Additional file 1.
In total, 3847 articles were identified via database searches (PubMed n = 1598, Scopus n = 1769, CINAHL n = 247, and PsycInfo n = 233). The reference lists of all eligible publications were also hand searched and eight additional articles were found (total 3855). After the removal of 613 duplicates, the remaining 3242 articles were screened on title and abstract and 2914 were excluded. After the full-text screening of the remaining 328 articles, 35 articles were identified that met the inclusion criteria. These 35 publications are based on 31 clinical studies, as four publications reported findings from other included studies.
At each stage, articles were screened by at least two authors, working independently in pairs, based on the inclusion and exclusion criteria (Table 1). Initial title and abstract screening were performed using the Covidence© online platform by AEB, CM, GDB, KL, KUM, SB and ZP. In case inclusion was unclear, a third expert author (KUM) was involved. Subsequent screening, hand searches, full-text review, final inclusion, and data extraction were done by SB and KUM. The selection process is illustrated in Fig. 2, based on the PRISMA (Preferred Reporting Items for Systematic reviews and Meta-Analyses) protocol, including reasons for exclusion at full-text screening [37 (link)].

To engineer gene-centric features of protein binding events and gene annotation and sequence composition features as predictors in our machine learning models we obtained transcript annotations for protein-coding genes and non-coding RNAs from the GENCODE (41 (link)) database for the hg19 (GrCH37) genome build. We obtained 81 745 annotated protein-coding transcripts for 20 167 genes. Of these transcripts, 30 186 (18 889 genes) were supported by RefSeq (42 (link)) annotations and selected as high-confidence transcripts for the analysis. From the annotations, we obtained 5-prime, intronic, coding exonic and 3-prime genomic regions for each transcript which served to capture interpretable binding sites when integrating CHIP-seq and eCLIP-seq data sets (see CHIP-seq data integration & eCLIPseq data integration). HUGO gene nomenclatures (HGNC) (43 (link)) from GENCODE were used to further annotate the transcripts with their respective gene symbols.
A set of non-coding transcripts was obtained through appropriate filtering of the GENCODE transcript annotation set for transcripts that were annotated as one of miscRNA, miRNA, snoRNA, snRNA and lincRNA which represent miscellaneous, micro, small nucleolar, small nuclear and long intervening RNA biotypes, respectively. These non-coding transcripts were used to engineer features for the machine learning task as well as other downstream analyses, especially in the context of the 7SK non-coding RNA (see Identification of 7SK Interacting Proteins). Analogous to the protein-coding transcripts, the genomic regions (5-prime, intronic, exonic, and 3-prime) of non-coding transcripts were used to create binding site features based on CHIP-seq and eCLIP-seq data sets.

Based on the trained NN model, we build a gene regulatory network by identifying for each predicted gene at the output of the NN, the genes at the input that contribute to the predicted value. Let F denote the function implemented by our NN model, and (y1, …, yN) = F(x1, …, xN, xct, xpid) the computation of the N output genes from the N input genes plus the ‘ct’ and ‘pid’ variables, we would like to identify for each data point a matrix of ‘relevance scores’ of size N × N containing the contribution of each input gene i to each output gene l.
The problem of computing these scores for some function F evaluated at some data point x is known as attribution. Many approaches have been proposed for attribution, e.g. (11 (link),24 ,25 ). Here, we use the Layer-wise Relevance Propagation (LRP) (11 (link)) approach for its robustness and advantageous computational properties as it lets us extract for each output yl the collection of scores in the order of a single forward/backward pass. The LRP procedure starts at the output of the NN with a particular predicted gene value yl and redistributes this score to the input of the NN in an iterative layer-wise manner. Let j and k be indices for neurons at two adjacent layers, and let aj and ak denote their respective activations. Activations at these two layers are related via the neuron equation: where jk, bk are the neuron parameters learned from the data, where ρ is a ReLU or linear activation function, and where ∑0, j sums over all input neurons j plus a bias (represented as a constant activation a0 = 1 and weight 0k = bk). Denote by Rk the relevance score that has been attributed on neuron k by propagation of yl from the top-layer back to the layer of neuron k. To propagate relevance scores one layer below (i.e. onto the layer of neuron j), we use the propagation rule: where ( · )+ and ( · ) are shortcut notations for max (0, ·) and min (0, ·). This rule is known as ‘generalized LRP-γ’, and used in (19 (link),26 ). The parameter γ is a hyperparameter that needs to be selected to maximize explanation quality. When reaching the input layer, we get 2 · N explanation scores representing gene contributions (each gene being represented as a pair of two values at the input of the NN), plus a few more scores associated to ‘ct’ and ‘pid’ features. We reach the desired N explanation scores by ignoring the ‘ct’ and ‘pid’ scores, and then reducing (i.e. summing) the remaining 2 · N scores into a N-dimensional vector representing the contribution of each gene.
The LRP procedure is repeated K =100 times for random sets of predicting genes and the ‘raw’ LRP score (which we denote by LRPr) is then defined as the average over these random sets of genes. LRPr scores are then computed for all predicted genes which leaves us with a N × N matrix of LRP scores representing gene-to-gene interactions. Subsequently, self-loops are excluded and the absolute undirected LRPau scores for every pair of genes A and B are calculated as .

scRNA-seq datasets of human atherosclerotic plaques were downloaded from GEO database and re-analysed using Cellranger (v6.1.2) [54 (link)]. The raw gene-expression matrix was transformed into a Seurat object using the Seurat package (v4.0.5) of R (v4.1.1) [55 ]. In order to exclude low-quality cells, cells with greater than 25,000 unique molecular identifiers (UMIs) were removed and only expressing between 200 and 4500 genes and genes expressed in at least 3 cells were used for further analysis. The doublet cells were further identified and removed from the remaining cells by R package DoubletFinder (v2.0.3) [56 ]. After the above quality control, the integration workflow recommended by Seurat 4 (v4.0.5) is followed [57 ]. We identified the “anchors” in the different batches to construct a reference. First, we used the “SplitObject” function to divide the combined object into a list. Before finding the anchors, log-normalisation was performed, and 2000 highly variable genes (HGVs) were identified using the “vst” method. Next, we used the “FindIntegrationAnchors” function with default parameters to identify the anchors. The “IntegrateData” function, which returns a Seurat object with a batch-corrected expression matrix for all cells, was used to integrate the batches using the anchors. All of these cells were subsequently dimensionally reduced based on HGVs and top 20 principal components estimated by an Elbow plot. The data clustering was done using the graph-based clustering approach implemented in the Seurat package’s “FindNeighbor” function with the top 20 principal components and “FindClusters” function with the “resolution” parameter set to 0.5. The “RunTSNE” function was used for the visualisation plot with the two-dimensional t-distributed stochastic neighbour embedding (t-SNE) model, setting “dims” to 1:30. And known cell lineages were assigned to major cell clusters projected in the t-SNE model using well-known marker genes. Cell clusters were then manually assigned to the major cell types in accordance with these established markers. Any cluster that had multiple markers for two different cell types was manually eliminated as a doublet. The “FindAllMarkers” function with default parameters was used to list the markers of all cell populations. For subclustering of the major cell populations (CD45+ cells, myeloid cells and T/NK cells), the same procedure of finding HGVs, removing batch effects, dimensionality reduction, and clustering were repeated. Any cluster with an extraordinarily high number of detected genes or UMI count was manually discarded as a doublet.
