KEOPS complex expression in the frontal cortex in major depression and schizophrenia.

ABSTRACT:

Objectives

Recently, the presence of a complete five subunit Kinase, Endopeptidase and Other Proteins of small Size (KEOPS) complex was confirmed in humans. The highly conserved KEOPS protein complex has established roles in tRNA modification, protein translation and telomere homeostasis in yeast, but little is known about KEOPS mRNA expression and function in human brain and disease. Here, we characterise KEOPS expression in post-mortem tissue from subjects diagnosed with major depression (MDD) and schizophrenia and assess whether KEOPS is associated with telomere length dysregulation in neuropsychiatric disorders.

Methods

We assessed mRNA expression of KEOPS complex subunits TP53RK, TPRKB, GON7, LAGE3, OSGEP, and OSGEP mitochondrial ortholog OSGEPL1 in the dorsolateral pre
