*Reactivity = the intensity of immunoreactivity with proteins on the microarray which were graded from 0 (no reactivity) to 4 (high intensity).

Abbreviations: ARM, ankyrin repeat motif; ARP, actin-related protein; ATP, adenosine triphospate; MAZI, Myc-associated zinc finger protein; NuMA, nuclear mitotic apparatus (NuMA) protein; VDAC1, voltage-dependent anion channel 1.
