Transcriptome alterations of mitochondrial and coagulation function in schizophrenia by cortical sequencing analysis

Area of Science:

• Neuroscience
• Genetics
• Molecular Biology

Background:

• Schizophrenia (SCZ) is linked to potential dysfunctions in energy metabolism and hemostasis.
• Genetic and protein interactions are implicated in SCZ pathogenesis, potentially affecting mitochondrial and coagulation functions.
• These dysfunctions may explain negative symptoms and antipsychotic-induced venous thromboembolism.

Purpose of the Study:

• To analyze transcriptome sequencing data from schizophrenia brain samples.
• To identify differentially expressed genes and their interactions.
• To evaluate the role of mitochondrial and coagulation pathways in SCZ.

Main Methods:

• Analysis of published BA22 RNA-Seq brain data from 9 SCZ patients and 9 controls.
• Identification of differentially expressed genes as SCZ candidate marker genes (SCZCGs).
• Pathway analysis using the Pathway Interaction Database (PID).

Main Results:

• Genetic interactions between mitochondrial genes and under-expressed SCZCGs suggest mitochondrial dysfunction in SCZ.
• SCZCGs are involved in DNA binding, transcription factor activity, signaling, cancer pathways, coagulation, and cell cycle regulation.
• Analysis revealed potential links between SCZ, energy metabolism, and hemostasis.

Conclusions:

• Energy metabolism and hemostatic processes are crucial in schizophrenia pathogenesis.
• Genetic interactions among co-expressed genes highlight key networks in SCZ pathology.
• Crosstalk analysis of overlapping genes can improve candidate gene identification for SCZ.
