OXT and cancer: Pathway annotations (KEGG) for genes with proximal promoter epigenetic activity are Pathways in cancer (p = 2.5 × 10−16), several pathways involved in neurotransmitter signaling and neurological pathogenesis, such as cholinergic synapse (p = 1.5 × 10−7), oxytocin signaling (p = 6.8 × 10−7), glutamatergic synapse (p = 9.4 × 10−7), dopaminergic synapse (p = 3.9 × 10−6), cAMP signaling (p = 5.6 × 10−5), amphetamine addiction (p = 1.2 × 10−5), serotoninergic synapse (p = 9.4 × 10−4), morphine addiction (2.7 × 10−3) and endocannabinoid signaling (p = 2.5 × 10−3).
