Schizophrenia is an incurable psychiatric illness that affects about 1% of the world's population. The symptoms usually appear in adult life and are divided into three categories: positive symptoms (hallucinations and delusions); negative symptoms (unsociability, depression and lack of motivation); and cognitive problems (difficulty concentrating, impaired executive functions and long-term memory failure). The treatment is usually performed with antipsychotics that are often inefficient or have many side effects. Clozapine is an antipsychotic known for its efficacy in relieving the symptoms of treatment-resistant patients. However, the drug can cause serious side effects and some patients may develop a metabolic syndrome, the most common symptoms of which include fast weight gain, cardiovascular problems and diabetes. Our project aims to treat human adipocytes with clozapine and to analyze 1) its proteomic profile in order to verify the biochemical pathways altered by the drug and 2) the expression profile of miRNAs, since the last have been described as endocrine signaling in tissue adipose. Our goal is to find molecular signatures that could elucidate the mechanisms of action by which clozapine causes metabolic syndrome in patients and, in the future, use that knowledge to associate the drug with the attenuating components and/or provide insights to improve the drug or even create a new drug.
