We also measured miR-1197 and AK2 levels in the blood of schizophrenia patients and healthy controls, observing a decrease in miR-1197 levels in schizophrenia patients (p = 0.001, Fig. 4C), with medians levels of 0.011 in schizophrenia patients and 4.195 in controls (Table 4). The gene discussed is AK2; the disease is schizophrenia.
