Our study also confirmed that there is suppression of GABAgeric markers (that is, downregulation in NPY, SST and RELN expression) and showed that gene networks involving 'synaptic transmission', 'behavior', 'neuropeptide signaling pathway' and 'calcium ion-binding' pathways were also significantly downregulated in schizophrenia. The gene discussed is NPY; the disease is schizophrenia.
