Across TCGA patient cohorts, RNA activity of the Serotonin receptor signaling pathway pathway is significantly associated with the protein abundance of multiple proteins, with the UCEC cohort showing a particularly strong set of associations.
The most reproducible pathway-associated proteins across cancer lineages are HRH1_S233, HRH1_S230, and CHRM1_S322, each associated with the pathway in up to 7 cancer types. Since the analysis shows associations rather than directional relationships, both pathway-to-partner and partner-to-pathway views are reported.
Each partner is linked to its corresponding Q-omics profile. The scatter plot shows the strongest association, Serotonin receptor signaling pathway activity versus HRH1_S233 in UCEC (Pearson r = 0.32).
