"A total of 39 co-expression modules (M1-M39) were defined, ranging in size from 36 members (M39) as the smallest and 473 members (M1) as the largest (Fig. 2A and supplemental Tables S3 and S4)"
"Four modules were identified as significantly enriched with proteins conferring greater cognitive resilience: M22 Synapse, M5 Synapse, M36 Exocytosis, and M30 Mitochondria/ER (Fig. 3A and supplemental Table S10). In addition, four modules were found to be significantly enriched for proteins conferring less cognitive resilience: M11 Proteosome, M15 MAPK signaling, M32 GPCR signaling, and M16 Gluconeogenesis (Supplemental Table S11).

?)Not a table, we can use biomaRt. If you check in the plasma_proteomics folder I mapped the SomaLogic data to genes, I believe using gene/protein symbols. But Uniprot IDs can also work. Read through the scripts in the baseline
folder to ger a general idea of how that proteomics analysis goes. I think it is script 03
that does the conversion and fixing of proteins. Note that in some cases for SomaLogic, there are measures of a protein complex, that has multiple subunits thay are each a gene (GeneA|GeneB
). That may also be true for Seyfried's TMT data.
Different than orthologs, protein subunits should all be present, and each should be counted (the equivalent of duplicate measures for gene orthologs). However we don't know the absolute ratios other than the previously defined structure of the complex (i.e. A tetramer with two copies of each subunit), so we just have to ascribe the measured value to each subunit, knowing one might be a little higher in quantity by mass because it's bigger, etc.
For 2
, we could do separate plots. BA6 tends to be thw more commonly examined, but if we have both plus TMT-AD, we might try to split them out into a proteomics tab versus a transcriptomics tab if there get to be too many buttons across the top. Although technically TREAT-AD is multiomics. But we are shifting that to the GSEA plot.

Great Job!
We need to generate the overlap enrichment plot for resilience associated proteomics modules in this paper:
