Methotrexate induces apoptosis and cytotoxicity, upregulates the expression of iNOS and COX-2, suppresses hippocampal neurogenesis, and induces pulmonary fibrosis. Methotrexate is used in the research of various immune and inflammation-related diseases such as arthritis, psoriasis, systemic lupus erythematosus, as well as pulmonary fibrosis and breast cancer.
