Proteomics analysis of post mortem brains of patients with schizophrenia showed alterations in the levels of energy metabolism-associated proteins, such as aldolase C (ALDOC), enolase 2 (ENO2), and glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (Saia et al., 2015). Here, GAPDH is linked to schizophrenia.
