In addition to accelerated brain aging, patients with SZ also exhibit signs of systemic aging. However, the potential causal or biological mechanisms between multisystem aging and schizophrenia remain unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We obtained SZ-associated single-nucleotide polymorphism (SNP) sets, aging gene data, and tissue-specific cis-expression quantitative trait locus (cis-eQTL) data of the cerebral cortex and other tissues from a previous two-stage genome-wide association study (GWAS), GeneCards database, and Genotype-Tissue Expression (GTEx) project. We employed tissue-specific Mendelian randomization (MR) analysis to elucidate the tissue-specific expression patterns of aging-related genes, and used the summary data-based MR (SMR) approach to obtain tissue aging-related genes associated with the risk of SZ development. We identified the potential aging-related pathways through which these tissue-specific cis-eQTLs may affect SZ using enrichment analyses. Finally, we explored the relationship between the identified crucial aging-related genes and predicted age difference (PAD) of the brain in our clinical patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We found that the expression of tissue-specific aging genes, including synuclein alpha (\n                      <jats:italic>SNCA<\/jats:italic>\n                      ), angiotensin I converting enzyme (\n                      <jats:italic>ACE<\/jats:italic>\n                      ), BRCA1 DNA repair-associated (\n                      <jats:italic>BRCA1<\/jats:italic>\n                      ), MutL homolog 1 (\n                      <jats:italic>MLH1<\/jats:italic>\n                      ), vascular endothelial growth factor A (\n                      <jats:italic>VEGFA)<\/jats:italic>\n                      , microtubule-associated protein tau (\n                      <jats:italic>MAPT<\/jats:italic>\n                      ), and age-related maculopathy susceptibility 2 (\n                      <jats:italic>ARMS2<\/jats:italic>\n                      ), may affect SZ.
