GABBR1 and cancer: (v) Besides the decreased expression of GABBR1 and that of the neuron adhesion molecule gene (NRCAM), three other genes in Table 1 with the highest scores were also found to be downregulated: the dihydrolipoamide dehydrogenase (DLD) [23] and the mineralocorticoid receptor (NR3C2) [24] in the prefrontal cortex of schizophrenic patients, whereas the mitogen-activated protein kinase 10 (MAPK10) was found to be silenced in several types of cancer [25].
