Protein expression levels of spindle and kinetochore associated complex subunit 2 (SKA2) in the prefrontal cortext (PFC) of normal controls, and suicide victims and nonsuicidal subjects from different diagnostic groups. The data are shown as percent of controls. Values are mean ± SD. (A) Mean protein expression levels of SKA2 in normal controls, depressed suicide victims, nonsuicidal depressed subjects, schizophrenic suicide victims, nonsuicidal schizophrenic subjects, and other (mainly substance abuse and/or conduct disorders) suicide victims. (a) Normal controls vs all suicides: P < .001. (b) All nonsuicidal vs all suicides: P < .05. (B)

Mean protein expression levels of SKA2 in normal controls, depressed suicide victims, nonsuicidal depressed subjects, schizophrenic suicide victims, nonsuicidal schizophrenic subjects, and other (mainly substance abuse and/or conduct disorders) suicide victims. *P < .05.
