CDH5 (ANCOVA: RIN F(2,62) = 5.783, p = 0.005) and OCLN (F(2,64) = 4.552, p = 0.014) mRNA expression levels in the “high inflammation schizophrenia” subgroup were significantly increased relative to the “low inflammation schizophrenia” subgroup (CDH5: 49%; OCLN: 63%) and the “low inflammation” control subgroup (CDH5: 69%; OCLN: 27%). This evidence concerns the gene OCLN and schizophrenia.
