BDNF and Anxiety: GNNenrich specific results include also several pathways within the three databases associated with the regulation of neuronal processes and various neurological conditions such as: “brain-derived neurotrophic factor (BDNF) signaling pathway” (Murer et al. 2001), “serotonin and anxiety” (Joling et al. 2018) and “neural crest differentiation” (Yang et al. 2017) (more details in Tables 6, 11, and 17, available as supplementary data at Bioinformatics online).
